Compiler flags not being passed into some packages' builds #6640
Description
Expected Result
I think my compiler flags should be being passed into my packages and used when compiling.
If I specify:
spack install [email protected]%[email protected] cflags="-g -O0" cppflags="-g -O0" cxxflags="-g -O0" fflags="-g -O0" +optimize+pic+shared arch=linux-rhel7-x86_64`
I then expect the compiler to use -g -O0.
Actual Result
Compilers flags are being ignored by multiple packages and instead developer specified flags are being used.
For the same example , zlib, I specifically see in the build:
icc -fPIC -O2 -D_LARGEFILE64_SOURCE=1 -DHAVE_HIDDEN -I. -c -o example.o test/example.c
