This function builds a simple test project using a combination of
Fortran and C (and optionally C++) to verify that the compilers are
compatible. The idea is to help projects report very early to users
that the compilers specified cannot mix languages.
This teaches the 'testing' test to try generator expressions in
arguments to add_test(NAME). This test case mimics a common use-case of
passing executables to test driver scripts. We excercise the syntax for
per-configuration target file names.
This is a new FortranCInterface.cmake module to replace the previous
prototype. All module support files lie in a FortranCInterface
directory next to it.
This module uses a new approach to detect Fortran symbol mangling. We
build a single test project which defines symbols in a Fortran library
(one per object-file) and calls them from a Fortran executable. The
executable links to a C library which defines symbols encoding all known
manglings (one per object-file). The C library falls back to the
Fortran library for symbols it cannot provide. Therefore the executable
will always link, but prefers the C-implemented symbols when they match.
These symbols store string literals of the form INFO:symbol[<name>] so
we can parse them out of the executable.
This module also provides a simpler interface. It always detects the
mangling as soon as it is included. A single macro is provided to
generate mangling macros and optionally pre-mangled symbols.
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.
Previously the Fortran test created a single executable containing C,
C++, and Fortran sources. This commit divides the executable into three
libraries corresponding to each language, and two executables testing
Fortran/C only and Fortran/C/C++ together. The result tests more
combinations of using the languages together, and that language
requirements propagate through linking.
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 try_compile command project mode builds an entire source tree
instead of one source file. It uses an existing CMakeLists.txt file in
the given source tree instead of generating one. This commit creates a
test for the mode in the TryCompile test.
This adds sample linker invocation lines for the Intel compiler on
Linux. In particular, this exercises the case when "ld" appears without
a full path.
The Sun Fortran compiler passes -zallextract and -zdefaultextract to the
linker so that all objects from one of its archives are included in the
link. This teaches the implicit options parser to recognize the flags.
We need to pass them explicitly on C++ link lines when Fortran code is
linked.
This extends the Fortran-to-C interface test to add a C++ source file.
The executable can only link with the C++ linker and with the proper
Fortran runtime libraries. These libraries should be detected by CMake
automatically, so this tests verifies the detection functionality.
This hack was created to help the Fortran test executables link to the
implicit C libraries added by BullsEye. Now that implicit libraries
from all languages are detected and included automatically the hack is
no longer needed.
This teaches the SystemInformation test to report the CMake log files
CMakeOutput.log and CMakeError.log from the CMake build tree and from
the SystemInformation test build tree. These logs may help diagnose
dashboard problems remotely.
This extends the Fortran/C interface test to require that the executable
link to the fortran language runtime libraries. We must verify that the
proper linker is chosen.
The commit "Avoid case change in ImplicitLinkInfo test" did not change
all of the paths to mingw, so some case change still occurs. This
changes more of them.
Since "get_filename_component(... ABSOLUTE)" retrieves the actual case
for existing paths on windows, we need to use an obscure path for mingw.
Otherwise the test can fail just because the case of the paths changes.
This tests the internal CMakeParseImplicitLinkInfo.cmake module to
ensure that implicit link information is extracted correctly. The test
contains many manually verified examples from a variety of systems.
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.
The command "set(... PARENT_SCOPE)" should never affect the calling
scope. This improves the Function test to check that such calls in a
subdirectory scope affect the parent but not the child.
When this test was renamed from DumpInformation to SystemInformation the
configured header that points the dump executable to the directory
containing information files was broken. No information has been dumped
by this test for 2 years! This fixes it.
The ExportImport test drives its Export and Import projects using the
same compiler and flags. This converts the ctest --build-and-test
command lines to use an initial cache file instead of passing all
settings on the command line.
We need a shorter command line to pass through VS 6 on Win98.
This approach reduces duplicate code anyway.
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

This extends the ExportImport test. The Export project creates a C++
static library and exports it. Then the Import project links the
library into a C executable. On most platforms the executable will link
only if the C++ linker is chosen correctly.
This test creates a C executable that links to a C++ static library. On
most platforms the executable will not link unless the C++ linker is
chosen correctly.
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.
