Summary: TI toolchain should not call ranlib
Description:
Currently building static libraries with TI toolchain ends with ranlib call
which apparently does something with the libraries because the linker complains:
...
Linking C static library libfoo.a
/path/to/CMake/2.8.12.2/linux/i386/bin/cmake -P
CMakeFiles/foo.dir/cmake_clean_target.cmake
/path/to/CMake/2.8.12.2/linux/i386/bin/cmake -E cmake_link_script
CMakeFiles/foo.dir/link.txt --verbose=1
/path/to/ar6x -r libfoo.a CMakeFiles/foo.dir/src/foo.c.obj
==> new archive 'libfoo.a'
==> building archive 'libfoo.a'
/usr/bin/ranlib libfoo.a
...
Linking C executable hello
/path/to/CMake/2.8.12.2/linux/i386/bin/cmake -E cmake_link_script
CMakeFiles/hello.dir/link.txt --verbose=1
/path/to/cl6x --run_linker --output_file=hello --map_file=hello.map libfoo.a
CMakeFiles/hello.dir/src/hello.c.obj
<Linking>
warning: archive symbol directory is missing from archive "libfoo.a"
I suggest to set up in TI-C.cmake the following:
set(CMAKE_C_ARCHIVE_FINISH)
to clean up call to ranlib on finishing archive.
I would also suggest to either set CMAKE_C_ARCHIVE_APPEND to
${CMAKE_C_ARCHIVE_CREATE}. Currently, since CMAKE_C_ARCHIVE_CREATE is declared
explicitly in TI toolchain support, but CMAKE_C_ARCHIVE_APPEND is inherited from
CMakeCInformation, it looks inconsistent:
/vob/tetra/tools/CMake/2.8.12.2/linux/i386/share/cmake-2.8/Modules/Compiler/TI-C.cmake(9):
set(CMAKE_C_ARCHIVE_CREATE <CMAKE_AR> -r <TARGET> <OBJECTS> )
/vob/tetra/tools/CMake/2.8.12.2/linux/i386/share/cmake-2.8/Modules/CMakeCInformation.cmake(181):
set(CMAKE_C_ARCHIVE_APPEND <CMAKE_AR> r <TARGET> <LINK_FLAGS> <OBJECTS> )
Similar update should also be performed in TI-CXX.cmake.
Steps to Reproduce:
$ cat CMakeLists.txt
cmake_minimum_required(VERSION 2.8.12.2 FATAL_ERROR)
project(hello C)
# Enable/disable following to observe the issue
set(CMAKE_C_ARCHIVE_FINISH)
add_library(foo src/foo.c)
add_executable(hello src/hello.c)
target_link_libraries(hello foo)
set_target_properties(hello PROPERTIES LINKER_LANGUAGE C)
$ cat src/foo.c
void foo(void)
{
}
$ cat src/hello.c
void foo(void);
int main(int argc, char *argv[])
{
foo();
return 0;
}
$ /path/to/cmake -DCMAKE_C_COMPILER=/path/to/cl6x -DCMAKE_SYSTEM_NAME=Generic .
$ make
Observe that in case that CMAKE_C_ARCHIVE_FINISH is not redefined, ranlib is run
and then linker complains:
warning: archive symbol directory is missing from archive "libfoo.a"
