Hi,
What is the correct way of setting archiver (and flags) and linker
(and flags) outside the CMakeLists.txt?
1) I am trying to use the following pattern:
cmake -DCMAKE_AR="<path-to-ar>" -DCMAKE_CXX_LINK_EXECUTABLE="<linker
path> <FLAGS> <CMAKE_CXX_LINK_FLAGS> <LINK_FLAGS> <OBJECTS> -o
<TARGET> <LINK_LIBRARIES>" -DSTATIC_LIBRARY_FLAGS="<flags>"
-DCMAKE_SHARED_LINKER_FLAGS="<flags>"
-DCMAKE_EXE_LINKER_FLAGS="<flags>"
Is that in general correct options to pass that information?
Judging by documentation, they are.
2) However, I am getting the following warning:
CMake Warning:
Manually-specified variables were not used by the project:
STATIC_LIBRARY_FLAGS
(Also, in CMakeCache.txt this variable is UNINITIALIZED)
If I am trying to use CMAKE_STATIC_LINKER_FLAGS, I get in the cache:
//Path to a program.
CMAKE_AR:FILEPATH=/usr/bin/ar
...
//Flags used by the linker during the creation of static libraries.
CMAKE_STATIC_LINKER_FLAGS:STRING=rcsD
But the link command looks like:
/usr/bin/ar qc libXXX.a rcsD file1.o .. filen.o
/usr/bin/ranlib libz.a
and I get the error:
/usr/bin/ar: rcsD: No such file or directory
Because the order of ar arguments is wrong, flags should come before "qc".
Thank you in advance
Irina
