Linux cc build error #70

Closed rajansaini691 closed 3 years ago

rajansaini691 commented 3 years ago

Getting the following error while building on Arch:

[ 37%] Building C object src/CMakeFiles/zynadds sf/tlsf.c.o
cc: error: unrecognized command-line option ‘--system-header-prefix=FL/’

I know that clang supports this option while gcc doesn't, but I'm not very familiar with the build system here. Any help would be appreciated!

Is this building with the build scripts here or is this building from the zynaddsubfx repo itself?

I wouldn't expect anything related to FLTK given the options set in these build scripts, but it's possible something is leaking through.

I think I used these build scripts; I ran ruby build-linux.rb. Do I need to install fltk?

You shouldn't need to. I'm mostly asking to verify system config for when I try to replicate the issue within docker. As long as I can replicate, then it should be possible to identify the mistake in zyn's CMakeLists.txt file(s).

I'd make sure your system is up to date, then make a new build folder, and hopefully the issue disappears. Using an arch docker (specifically https://github.com/zynaddsubfx/zyn-fusion-build/blob/master/linux-system-testers/arch-zynaddsubfx.dockerfile ) I can not replicate the issue. I see the line in our cmake files which was introducing the compiler argument, but it only gets included if the compiler passes a test indicating it's a usable flag. With all the runs I was able to make the compiler flag was detected as unusable in gcc and thus did not get used.

Let me know if you have a method for replicating, but if I can't repeat the situation within a constrained setup like docker I'm stumped.
