CMake not detecting ${GNUCC_ARCH} on Arch Linux, gcc 9.2
I have just cloned Hyperscan to my machine and am building it. Os is Arch Linux with latest kernel and GCC and I had some trouble with CMake. It repported error with Unix Makefiles generator. It didn't found the right architecture for -mtune flag.
The macro was in CMakeLists.txt, line 196:
set (EXEC_ARGS ${CC_ARG1} -E - -mtune=${GNUCC_ARCH})
Changing this to:
set EXEC_ARGS ${CC_ARG1} -E - -mtune=native)
seems to fix the issue. At least it did for me, Hyperscan seems to have built fine.
Can you show us the output of gcc -c -Q --help=target -march=native -mtune=native on your system?

Thanks. They look find to me.
string(REGEX REPLACE ".*march=[ \t]*([^ \n]*)[ \n].*" "\\1" should be able to extract skylake from the line -march= skylake in your output.
Can you print out the value of ${GNUCC_ARCH}?
Sorry, I am not sure what do you want me to do? ${GNUCC_ARCH}, is that a cmake macro? How do I extract that?
Just for the curiosity, why? Can you not just use -mtune=native and -march=native and let gcc do it on it's own? Why bother to pass it from within cmake? Or am I missing something?
The macro was in CMakeLists.txt, line 196:
set (EXEC_ARGS ${CC_ARG1} -E - -mtune=${GNUCC_ARCH})
As you mentioned that CMake didn't found the right architecture for -mtune flag, then the value of GNUCC_ARCH shouldn't be valid. If so, it'll be good to know its value.
We used to have -mtune=native and -march=native, but the generated instructions by GCC weren't consistent with that of explicitly specifying the CPU architecture, which may impact our performance in some cases.
It was none, empty string. At least what I believe. I have edited back cmakelists.txt and run cmake to generate makefiles, this is what I get:

When I change back from -mtune=${GNUCC_ARCH} to -mtune=native it generates makefiles fine, and I can build hyperscan.
Is there some way I can see what value of GNUCC_ARCH evalutes to in cmake? I am sorry I am not that versatile with cmake. Tried some options I found on SX, but didn't give me anything reasonable.
