Mikołaj Siedlarek 1bed75a590 OS X: Use -iframework for system framework directories
Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.

Stephen Kelly 205215fb8a cmTarget: Add CXX_STANDARD_REQUIRED to control decay. 2014-05-07 12:17:49 +02:00
Stephen Kelly 1df2116bfa Features: Decay language flag if requested is not available.
Use the highest standard compile flags available if requested language
version is too new.

This supports use-cases like

 set(CMAKE_CXX_STANDARD 14)

 # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
 # or equivalent flag
 add_executable(main main.cpp)

This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.

Stephen Kelly 5412deded1 cmTarget: Transitively evaluate compiler features.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.

Use the same pattern of origin-debugging which is used for other
build properties.

Casts from std::string -> cmStdString were high on the list of things

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Brad King fba51b096e MSVC: Add properties to configure compiler PDB files (#14762)
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties.  Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important.  Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.

Brad King d2059d2511 cmVersion: Fix CMake_VERSION_ENCODE for date in patch level
Use a uint64_t to store encoded version numbers so we have plenty of
bits available.  Encode with room for up to 1000 minor releases between
major releases and to encode dates until the year 10000 in the patch
level.  This is necessary because CMake development versions prior to
release 2.8.0 used the date in the patch level, and this practice may be
restored after the 3.0 release.

Rolf Eike Beer c768e398f9 cmMakefile: make some methods take const std::string& instead of const char*
Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.

Stephen Kelly 0bfcb450e6 INTERFACE_LIBRARY: Avoid codepaths which set unneeded properties.
As an INTERFACE_LIBRARY has no direct link dependencies, we can
short-circuit in cmGeneratorExpressionEvaluator and
in cmGlobalGenerator::CheckLocalGenerators.

As they do not generate any output directly, any generate- or install-
related code acn also be short-circuited. Many of the local generators
already do this.

Because only INTERFACE related properties make sense on INTERFACE_LIBRARY
targets, avoid setting other properties, for example via defaults.
2013-11-25 16:17:50 +01:00
Stephen Kelly 7521da2852 Introduce CMAKE_STAGING_PREFIX variable.
This variable can be useful in cross-compiling contexts where the
sysroot is read-only or where the sysroot should otherwise remain
pristine.

If the new CMAKE_STAGING_PREFIX variable is set, it is used instead
of CMAKE_INSTALL_PREFIX when generating the installation rules in
cmake_install.cmake.

This way, the CMAKE_INSTALL_PREFIX variable
always refers to the installation prefix on the target device, regardless
of whether host==target.

If any -rpath paths passed to the linker contain the CMAKE_STAGING_PREFIX,
the matching path fragments are replaced with the CMAKE_INSTALL_PREFIX.
Matching paths in the -rpath-link are not transformed.

The cross-prefix usr-move workaround is assumed not to require extension
regarding CMAKE_STAGING_PREFIX. The staging area is a single prefix, so
there is no scope for cross-prefix symlinks. The CMAKE_INSTALL_PREFIX
is still used to determine the workaround path, and that variable
remains the relevant one even if CMAKE_STAGING_PREFIX is used. If the
generated export files are deployed to the target, the workaround
will still be in place, and still be employed if required.

Stephen Kelly 7cd65c97fa Add CMAKE_SYSROOT variable to set --sysroot when cross compiling.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is

The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.

Stephen Kelly 5096967ecd Allow toolchain files to specify an external toolchain.
Clang can compile code, but uses the gcc tools for other tasks such
as linking. The -gcc-toolchain option can be used for that, but
generalize so that other compilers can be treated the same.

If such a location is specified, use it as a hint for finding
the binutils executables.
2013-11-19 12:39:34 -05:00
Stephen Kelly 76552d595d Add compiler target compile options.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like

 set(triple arm-linux-gnueabihf)
 set(CMAKE_C_COMPILER "/usr/bin/clang")
 set(CMAKE_C_COMPILER_TARGET ${triple})
 set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
 set(CMAKE_CXX_COMPILER_TARGET ${triple})

or

 set(arch gcc_ntoarmv7le)
 set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
 set(CMAKE_C_COMPILER_TARGET ${arch})
 set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
 set(CMAKE_CXX_COMPILER_TARGET ${arch})

Both clang and qcc are inherently cross compiler( driver)s.

When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET
as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils.

When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET
to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.

Stephen Kelly fe732264e9 Add the INTERFACE_LIBRARY target type.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.

The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.

An ALIAS target may be created for an INTERFACE library.

At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.

The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.

Brad King 4bb6e24809 VS,Xcode: Drop incorrect legacy dependency trace (#14291)
Drop the "vsProjectFile" argument from cmTarget::TraceDependencies.  It
appears to be the modern equivalent to a hunk added in commit ba68f771
(...added new custom command support, 2003-06-03):

 +  name = libName;
 +  name += ".dsp.cmake";
 +  srcFilesToProcess.push(name);

but was broken by refactoring at some point.  The current behavior tries
to trace dependencies on a source file named the same as a target, which
makes no sense.  Furthermore, in code of the form

 add_executable(foo foo.c)
 add_custom_command(OUTPUT "${somewhere}/foo" ... DEPENDS foo)

the "vsProjectFile" value "foo" matches source "${somewhere}/foo.rule"
generated to hold the custom command and causes the command to be added
to the "foo" target incorrectly.

Simply drop the incorrect source file trace and supporting logic.

Brad King d221eac812 Refactor target COMPILE_OPTIONS and COMPILE_FLAGS handling
Replace the cmLocalGenerator GetCompileOptions method with an
AddCompileOptions method since all call sites of the former simply
append the result to a flags string anyway.

Add a "lang" argument to AddCompileOptions and move the
CMAKE_<LANG>_FLAGS_REGEX filter into it.  Move the call sites in each
generator to a location that has both the language and configuration
available.  In the Makefile generator this also moves the flags from
build.make to flags.make where they belong.

Brad King b6385cabec Escape target flags taken from COMPILE_OPTIONS
Factor appending of individual flags out into an AppendFlagEscape method
in cmLocalGenerator and teach it to use EscapeForShell.  Update all
COMPILE_OPTIONS handling to use AppendFlagEscape.

Override the method in the Xcode generator to use its custom escape
implementation.

Teach the CompileOptions test to add an option that requires escaping
everywhere instead of just with the GNU tools.

For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like

 set(triple arm-linux-gnueabihf)
 set(CMAKE_C_COMPILER "/usr/bin/clang")
 set(CMAKE_C_COMPILER_TARGET ${triple})
 set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
 set(CMAKE_CXX_COMPILER_TARGET ${triple})

or

 set(arch gcc_ntoarmv7le)
 set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
 set(CMAKE_C_COMPILER_TARGET ${arch})
 set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
 set(CMAKE_CXX_COMPILER_TARGET ${arch})

Both clang and qcc are inherently cross compiler( driver)s.

Stephen Kelly de4da665d3 Use --sysroot when cross compiling.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.

The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.

Stephen Kelly 753b905ec8 Automoc: append implicit includes after user-specified dirs
The commit d2536579 (Automoc: fix regression #13667, broken build in
phonon, 2012-11-19) changed Automoc to try to re-add the Qt header dir
if it was stripped out as an implicit include from the moc command
line. When invoking a compiler, those directories are stripped out
because they are built-in, but for moc, there are no built-in directories.

The follow-up commit acc22400 (Automoc: get include dirs without
stripping implicit include dirs off, 2012-12-07) went further by not
removing the implicit include dirs, if they were specified specifically
by the user.

This had the remaining problem that the implicit include dirs appeared
in a different order of precedence for moc compared to the compiler.
Resolve that by stripping out the include dirs, where specified for
the moc command line to, and then appending them at the end. Note that
the order of the appended implicit include directories is the order
they are specified in the CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, not
the order specified by the user.

Stephen Kelly 1714c27a74 Process generator expressions for 'system' include directories.
Since commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property., 2012-09-18), it is possible to use
generator expressions with the include_directories command.

As that command can also have a SYSTEM argument, ensure that the
result of using that argument with generator expressions gives a
sane result.

Stephen Kelly 3581b96caa Process the INTERFACE_PIC property from linked dependencies
This allows a dependee to inform a target that it should have its
POSITION_INDEPENDENT_CODE property set to ON, or OFF. The value of
the POSITION_INDEPENDENT_CODE property, if set, must be consistent
with any INTERFACE_POSITION_INDEPENDENT_CODE properties on dependees.

Add a test covering the consistency checks on platforms where they run.

Refactoring in commit 8d674e78 (Ninja: move -LIBPATH behind -link

This should finally fix #13667 and #13762.
Instead of adding special handling to guess whether implicit include dirs

without removing the implicit ones.

David Cole 7ae7d66503 NMake: Fix problem with empty DEPENDS args (#13392)
add_custom_command can have empty DEPENDS arguments, which
was triggering invalid makefile generation for the NMake
Makefiles generator. We were mistakenly emitting the build
directory appended with "/" plus the empty string... which
was then translated to a string ending in \" in build.make...
which nmake choked on.

The solution is not to emit any dependency when the input
DEPENDS is the empty string. Return early from GetRealDependency
in this empty input case.

Stephen Kelly 95d590ddba GenEx: Create cmGeneratorTargets for imported targets.
We're going to need to link to them, and all the linking API is moving
to cmGeneratorTarget.

Skip imported targets when iterating over cmGeneratorTargets in places
where we only want targets we build.  The GetGeneratorTargets result now
includes IMPORTED targets where it didn't before.  The GetTargets
result, which was what used to be called in these methods does not
include IMPORTED targets.  This doesn't relate to any known bugs, but in
some future uses of GetGeneratorTargets it will be important, so
starting the convention and being deliberate now is a good idea.
