CTest runs 'svn status' to identify modified and conflicting files in
the working directory. This commit fixes the interpretation of the 'X'
status, which corresponds to svn eXternals. This status should be
ignored rather than treated as a local modification.
This introduces a new syntax called "generator expressions" to the test
COMMAND option of the add_test(NAME) command mode. These expressions
have a syntax like $<TARGET_FILE:mytarget> and are evaluated during
build system generation. This syntax allows per-configuration target
output files to be referenced in test commands and arguments.
We creates methods IsDLLPlatform() and HasImportLibrary(). The former
returns true on Windows. The latter returns whether the target has a
DLL import library. It is true on Windows for shared libraries and
executables with exports.
We teach cmTestGenerator::GenerateScriptConfigs to use the general
cmLocalGenerator::EscapeForCMake method to write escaped test property
values into test scripts. This eliminates the previous hand-coded
escaping implementation.
The find_package commands looks at the "WhereBuild" registry entries
created by CMakeSetup and cmake-gui hoping that the project was recently
built. CMakeSetup created WhereBuild1..WhereBuild10 but cmake-gui
creates WhereBuild0-WhereBuild9.
This fixes find_package to look at WhereBuild0 so that the most recently
configured project can be found. It is important in the case that the
package to be found was the last one configured in cmake-gui but the
current project that is finding it is configured from the command line.
The try_compile command builds the cmTryCompileExec executable using the
cmTryCompileExec/fast target with Makefile generators in order to save
time since dependencies are not needed. However, in project mode the
command builds an entire source tree that may have dependencies.
Therefore we can use the /fast target approach only in one-source mode.
When building an entire source tree with try_compile instead of just a
single source file, it is possible that the CMakeLists.txt file in the
try-compiled project invokes try_compile. This commit fixes propagation
of language-initialization results from the outer-most project into any
number of try-compile levels.
The commit "Fix get_filename_component ABSOLUTE mode" broke the code
get_filename_component(cwd . ABSOLUTE)
because CTest scripts did not make cmMakefile::GetCurrentDirectory()
available. This commit fixes the problem by setting the proper
information on CTest script instances of cmMakefile.
This also makes CMAKE_CURRENT_SOURCE_DIR and CMAKE_CURRENT_BINARY_DIR
available to CTest scripts. They are set to the working directory at
script startup.
CMake 2.4 generates old-style cmake_install.cmake code including calls
to the file(INSTALL) command with the COMPONENTS argument. We need to
set CMAKE_INSTALL_SELF_2_4 for the whole install tree to prevent the
command from complaining in this special case. Previously this was
needed only in the QtDialog directory, but now it is needed in the
entire tree.
The commit "Consider link dependencies for link language" taught CMake
to propagate linker language preference from languages compiled into
libraries linked by a target. It turns out this should only be done for
some languages, such as C++, because normally the language of the
program entry point (main) should be used.
We introduce variable CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES to tell
CMake whether a language should propagate its linker preference across
targets. Currently it is true only for C++.
This factors the decision logic out of cmTarget::ComputeLinkClosure into
dedicated class cmTargetSelectLinker. We replace several local
variables with a single object instance, and organize code into methods.
All global generator CreateLocalGenerator methods automatically
initialize the local generator instances with SetGlobalGenerator. In
several places we were calling SetGlobalGenerator again after receiving
the return value from CreateLocalGenerator. The double-initializations
leaked the resources allocated by the first call to SetGlobalGenerator.
This fix removes the unnecessary calls.
We list implicit link items of languages linked into a target but filter
them by the implicit libraries known to be passed by the main linker
language. Implicit link flags like "-z..." should not be filtered out
because they are not libraries.
In cmComputeLinkInformation we recognize link options that look like
library file names, but pass flags starting in '-' through untouched.
This fixes the ordering of the check to recognize '-' flags first in
case the rest of the option looks like a library file name, as in the
case of "-l:libfoo.a".
In cmComputeLinkInformation we construct regular expressions to
recognize library file names. This fixes the expressions to not allow a
colon (':') in the file name so that "-l:libfoo.a" is left alone.
Some AIX/gcc version combinations the <cstdio> header breaks when large
file support is enabled. See this GCC issue for details:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20366
We work around the problem by enhancing the configuration check for
large file support to include <cstdio> when available. This will cause
LFS to be disabled when the above problem occurs.
This adds implicit libraries and search directories for languages linked
into a target other than the linker language to its link line. For
example, when linking an executable containing both C++ and Fortran code
the C++ linker is used but we need to add the Fortran libraries.
The variables
CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
contain the implicit libraries and directories for each language.
Entries for the linker language are known to be implicit in the
generated link line. Entries for other languages that do not appear in
the known implicit set are listed explicitly at the end of the link
line.
The "Keep only FinalPass commands in memory" commit caused instances of
this command to be deleted after the InitialPass. Even though the
variable_watch command does not have a final pass, it does need to stay
alive because it owns the callback information.
In cmMakefile we save all invoked commands so that FinalPass can be
called on them later. Most commands have no final pass, so we should
keep only the few that do.
This teaches CMake to detect implicit link information for C, C++, and
Fortran compilers. We detect the implicit linker search directories and
implicit linker options for UNIX-like environments using verbose output
from compiler front-ends. We store results in new variables called
CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
The implicit libraries can contain linker flags as well as library
names.
This teaches the command to recognize full windows paths when built on
UNIX. CollapseFullPath knows when the input path is relative better
than FileIsFullPath because the latter is only meant for paths from the
host platform.
Previously each new variable scope (subdirectory or function call) in
the CMake language created a complete copy of the key->value definition
map. This avoids the copy using transitive lookups up the scope stack.
Results of queries answered by parents are stored locally to maintain
locality of reference.
The class cmDefinitions replaces cmMakefile::DefinitionsMap, and is
aware of its enclosing scope. Each scope stores only the definitions
set (or unset!) inside it relative to the enclosing scope.
Generated makefiles for try-compile projects should never use color
output. On MSYS the color escapes end up in the try-compile output text
because there is no way to identify whether the output is going to a
color-capable terminal. Instead we should just always skip color for
try-compile projects.
This factors code out of cmOrderDirectories::CollectOriginalDirectories
into cmOrderDirectories::AddOriginalDirectories. Later a new call will
be added, and this is more readable anyway.
Add System_Parse_CommandForUnix to the KWSys System interface as a
utility to parse a unix-style command line. Move the existing
implementation out of ProcessUNIX. Add a flags argument reserved for
future use in providing additional behavior.
cmCTestScriptHandler, but have it load the new script CTestScriptMode.cmake
-> that makes it more flexible, also add a simple test that the system name
has been determined correctly

Now that languages are part of the link interface of a target we need to
export/import the information. A new IMPORTED_LINK_INTERFACE_LANGUAGES
property and per-config IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
property specify the information for imported targets. The export() and
install(EXPORT) commands automatically set the properties.
Xcode does not seem to support direct requests for using the linker for
a particular language. It always infers the linker using the languages
in the source files. When no user source files compile with target's
linker language we add one to help Xcode pick the linker.
A typical use case is when a C executable links to a C++ archive. The
executable has no C++ source files but we need to use the C++ linker.
This teaches cmTarget to account for the languages compiled into link
dependencies when determining the linker language for its target.
We list the languages compiled into a static archive in its link
interface. Any target linking to it knows that the runtime libraries
for the static archive's languages must be available at link time. For
now this affects only the linker language selection, but later it will
allow CMake to automatically list the language runtime libraries.
This creates cmCTestHG to drive CTest Update handling on hg-based work
trees. Currently we always update to the head of the remote tracking
branch (hg pull), so the nightly start time is ignored for Nightly
builds. A later change will address this.
See issue #7879. Patch from Emmanuel Christophe. I modified the patch
slightly for code style, to finish up some parsing details, and to fix
the test.
This overload accepts a null-terminated string instead of requiring a
length. It is useful to pass some fake process output before and after
the real process output.
This adds another cast to avoid pointer conversion warnings.
Unfortunately C does not recognize implicit conversions that add
cv-qualifiers as well as C++ does.
The commit "Do not compute link language for LOCATION" was wrong. The
variables
CMAKE_STATIC_LIBRARY_PREFIX_Java
CMAKE_STATIC_LIBRARY_SUFFIX_Java
are used for building Java .jar files. This commit re-enables the
feature and documents the variables:
CMAKE_EXECUTABLE_SUFFIX_<LANG>
CMAKE_IMPORT_LIBRARY_PREFIX_<LANG>
CMAKE_IMPORT_LIBRARY_SUFFIX_<LANG>
CMAKE_SHARED_LIBRARY_PREFIX_<LANG>
CMAKE_SHARED_LIBRARY_SUFFIX_<LANG>
CMAKE_SHARED_MODULE_PREFIX_<LANG>
CMAKE_SHARED_MODULE_SUFFIX_<LANG>
CMAKE_STATIC_LIBRARY_PREFIX_<LANG>
CMAKE_STATIC_LIBRARY_SUFFIX_<LANG>
Instead of making separate, repetitive entries for the _<LANG> variable
documentation, we just mention the per-language name in the text of the
platform-wide variable documentation. Internally we keep undocumented
definitions of these properties to satisfy CMAKE_STRICT mode.
This passes the build configuration to most GetLinkerLanguage calls. In
the future the linker language will account for targets linked in each
configuration.
This simplifies computation of the lastKnownFileType attribute for
header files in Xcode projects. We now use a fixed mapping from
header file extension to attribute value. The value is just a hint to
the Xcode editor, so computing the target linker language is overkill.
The LOCATION property requires the full file name of a target to be
computed. Previously we computed the linker language for a target to
look up variables such as CMAKE_SHARED_LIBRARY_SUFFIX_<LANG>. This led
to locating all the source files immediately instead of delaying the
search to generation time. In the future even more computation will be
needed to get the linker language, so it is better to avoid it.
The _<LANG> versions of these variables are undocumented, not set in any
platform file we provide, and do not produce hits in google. This
change just removes the unused feature outright.
The new method centralizes loops that process raw OriginalLinkLibraries
to extract the link implementation (libraries linked into the target)
for each configuration. Results are computed on demand and then cached.
This simplifies link interface computation because the default case
trivially copies the link implementation.
These member structures are accessed only in the cmTarget implementation
so they do not need to be defined in the header. This cleanup also aids
Visual Studio 6 in compiling them.
The config-to-interface map in cmTarget should use case-insensitive
configuration names. The change avoids repeating work if the given
configuration has a different case than one already computed.
This fixes a dumb logic error introduced by the centralization of link
interface computation. It prevented link directories from alternate
configurations from getting listed by the OLD behavior of CMP0003 for
targets linked as transitive dependencies.
This method previously required the global generator to be passed, but
that was left from before cmTarget had its Makefile member. Now the
global generator can be retrieved automatically, so we can drop the
method argument.
When LINK_INTERFACE_LIBRARIES is not set we use the link implementation
to implicitly define the link interface. These changes centralize the
decision so that all linkable targets internally have a link interface.
This moves code implementing policy CMP0004 into cmTarget::CheckCMP0004.
The implementation is slightly simpler and can be re-used outside of
cmComputeLinkDepends.
This fixes cmTarget::GetLinkInterface to compute and return the link
interface in an exception-safe manner. We manage the link interface
returned by cmTarget::ComputeLinkInterface using auto_ptr.
This teaches the makefile generators to always pass the configuration
name to the cmTarget::GetDirectory method. Later this will allow
per-configuration target output directories, and it cleans up use of the
current API.
This creates cmTarget::GetOutputInfo to compute, cache, and lookup
target output directory information on a per-configuration basis. It
avoids re-computing the information every time it is needed.
Since utility targets have no main output files like executables or
libraries, they do not define an output directory. This removes a call
to cmTarget::GetDirectory from cmLocalVisualStudio{6,7}Generator for
such targets.
This member stores the build configuration for which Makefiles are being
generated. It saves repeated lookup of the equivalent member from
cmLocalUnixMakefileGenerator3, making code shorter and more readable.
Previously tests marked with WILL_FAIL have been reported by CTest as
...............***Failed - supposed to fail
when they correctly failed. Now we just report ".....Passed" because
there is no reason to draw attention to something that works as
expected.
Xcode 2.0 and below supported only one configuration, but 2.1 and above
support multiple configurations. In projects for the latter version we
have been generating a "global" set of buildSettings for each target in
addition to the per-configuration settings. These global settings are
not used by Xcode 2.1 and above, so we should not generate them.
The cmGlobalXCodeGenerator::CreateBuildSettings had the three arguments
productName, productType, and fileType that returned information used by only
one of the call sites. This change refactors that information into separate
methods named accordingly.
Previously we named Xcode targets using the output file name from one of the
configurations. This is not very friendly, especially because it changes with
CMAKE_BUILD_TYPE. Instead we should use the original logical target names for
the Xcode target names. This is also consistent with the way the other IDE
generators work.
CMake previously generated Xcode project files labeled as 2.4-compatible
by recent versions of Xcode (3.0 and 3.1). It is better to generate
native Xcode 3.0 and 3.1 projects. In particular, this can improve
build times by using the "Build independent targets in parallel"
feature.
Patch from Doug Gregor. See issue #9216.
files of the project, i.e. there is now a "CMake Files" folder additionally
to the "Sources", "Headers" and "Others" folders which already existed.

This cleans up the Makefile generator's progress rule code. Instead of
keeping every cmMakefileTargetGenerator instance alive to generate
progress, we keep only the information necessary in a single table.
This approach keeps most of the code in cmGlobalUnixMakefileGenerator3,
thus simplifying its public interface.
The TortoiseCVS version of cvs.exe includes the '.exe' in cvs update
messages for files removed from the repository. This change accounts
for it in the regular expressions that match such lines. Now removed
files are properly reported by ctest_update() when using TortoiseCVS.
