In targets with no non-header files the linker language cannot be
determined. Since the target project file cannot be generated at all in
this case, give up as soon as it is detected. Otherwise the generation
code may try to run with uninitialized information.
The original implementation of this generator accidentally used
"$(Configuration)/" for source-specific object file names. Correct it
to use "$(IntDir)/" just like the generators for all previous VS
versions. The target-wide output directory is "$(IntDir)/" already.
VS2010 uses IntDir as the location for writing log files for
what happens during custom build steps. With no IntDir settings,
all ExternalProject usage within the same CMakeLists.txt file
would result in multiple utility targets all trying to use the
same custom build log files.
With parallel builds, they would try to use them simultaneously
and result in file access errors, preventing the builds from
completing successfully.
Now each utility target has its own IntDir setting, and so, its
own custom build rule log files.
When none of the options /Z7, /Zi and /ZI are specified in the cmake
project settings, the project will open in the editor with "Program
Database" as the default debug information format, ending up always
generating PDBs regardless of project configuration.
Modify the output project file so that if the debug information format
is not specified in the cmake project settings it will default to no PDB
generated, just like all the previous other Visual Studio versions.
This problem comes from the fact that Microsoft changed the default
setting of the debug information format to be "Program Database" instead
of "Disabled".
Only generate .filters files if they are different than the last time
they were generated. This should prevent the unnecessary reloads
being triggered with Visual Studio 2010 builds.
The list of libraries to be linked into the current target must be
specified using windows slashes to that UNC paths such as
\\server\share\somelibrary.lib
work correctly. See issue #9917.
The reverted commit attempted to preserve the "../" PREFIX work-around
for avoiding per-config build directories in the VS IDE generators.
However, the original reporter has concluded that a "../" PREFIX no
longer works everywhere in VS 10 project files anyway. Rather than set
OutputPath, this commit restores the $(OutDir)$(TargetName)$(TargetExt)
default.
See issue #9768.
This commit teaches the VS 10 generator to detect the -D_UNICODE option
in preprocessor definitions and set the CharacterSet attribute to the
value 'Unicode'. This was already done for other VS IDE versions.
See issue #9769
The default $(OutDir)$(TargetName)$(TargetExt) for this value works in
most cases because we set the three properties. However, if the target
property PREFIX contains a path component (not documented but happens to
work in other VS generators) we drop it from TargetName and do not put
it in OutDir either. This commit corrects the resulting path by setting
the OutputPath property explicitly with the full path.
See issue #9768.
MS changed the location of the Microsoft.Cpp.$(Platform).user.props
file. This commit teaches the VS 10 generator about the new location.
See issue #9759.
In VS 8 and greater this commit implements
add_dependencies(myexe mylib) # depend without linking
by adding the
LinkLibraryDependencies="false"
option to project files. Previously the above code would cause myexe to
link to mylib in VS 8 and greater. This option prevents dependencies
specified only in the solution from being linked. We already specify
the real link library dependencies in the project files, and any project
depending on this to link would not have worked in Makefile generators.
We were already avoiding this problem in VS 7.1 and below by inserting
intermediate mylib_UTILITY targets. It was more important for those
versions because if a static library depended on another library the
librarian would copy the dependees into the depender! This is no longer
the case with VS 8 and above so we do not need that workaround.
See issue #9732.
We recognize .def source files and map them to the /DEF:<file> option in
the MSVC tools. Previously this worked only for shared libraries. This
commit cleans up the implementation and makes it work for executables
too. See issue #9613.
When constructing cmVisualStudioGeneratorOptions to parse options for
tools 'link' and 'lib' the tool type is now Linker, not Compiler. This
tells it not to recognize flags starting in '/D' as preprocessor macros,
such as the '/DEF:<file>' linker option. See issue #9613.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
Visual Studio 10 uses MSBuild to drive the build. Custom commands
appear in MSBuild files inside CustomBuild elements, which appear inside
ItemGroup elements. The Outputs and AdditionalInputs elements of each
CustomBuild element are evaluated according to timestamps on disk.
MSBuild does not use inputs/outputs to order CustomBuild steps within a
single ItemGroup or across multiple ItemGroup elements. Instead we must
put only unrelated CustomBuild elements in a single ItemGroup and order
the item groups from top to bottom using a topological order of the
custom command dependency graph.
This fixes CustomCommand and ExternalProject test failures, so we remove
the expectation of these failures.
Until now the VS 10 generator did no Windows command-line escaping and
just did XML escapes. This commit teaches the generator to use the same
command-line escape addition code used by other generators. The script
construction method cmLocalVisualStudioGenerator::ConstructScript need
not do XML escapes. Each VS generator version adds the XML escapes
necessary for that version.
This passes the build configuration to most GetLinkerLanguage calls. In
the future the linker language will account for targets linked in each
configuration.
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.
