Hi
When enable ccache for ceph, error occurs:
-----------------------------------------------------
ccache: invalid option -- 'E'
...
Unable to determine C++ standard library, got .
-----------------------------------------------------
This is because variable "CXX_STDLIB" was null in CMakeLists.txt line: 637,
The "CXX_STDLIB" come from:
-----------------------------------------------------
execute_process(
COMMAND ./librarytest.sh ${CMAKE_CXX_COMPILER} ${CMAKE_CXX_FLAGS}
WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}
OUTPUT_VARIABLE CXX_STDLIB
)
-----------------------------------------------------
The script librarytest.sh in ceph accept argument: compile and flags,
but when
enable ccache, the compile replace by ccache, so that script failed.
How can I solve it?
