Summary: CHECK_C_COMPILER_FLAG doesn't work with -march=xlr
option with a MIPS gcc cross compiler
Description:
I 've a CMakeLists.txt file as below.
CHECK_C_COMPILER_FLAG (-march=xlr FLAG_xlr)
CHECK_C_COMPILER_FLAG (-march=xlp FLAG_xlp)
I'm using a gcc MIPS cross compiler. Using this cross compiler I'm able to
compile a simple C program using both -march=xlr and -march=xlp compiler
options. The size of a.out differs with these two options (just to show that
-march option is acted upon by the compiler)
When I invoke cmake on above CMakeLists.txt file, I get the following.
-- Performing Test FLAG_xlr
-- Performing Test FLAG_xlr - Failed
-- Performing Test FLAG_xlp
-- Performing Test FLAG_xlp - Success
It says Test FLAG_xlr failed, but it shouldn't fail since the cross compiler
does support -march=xlr option.
Steps to Reproduce:
As described above.
I cannot provide the gcc cross compiler used since it's not publicly available.
