MIPS64: Compilation error on Ubuntu 24.04 #29

When compiling gnu-efi for mips64 on Ubuntu 24.04 (make ARCH=mips64 CROSS_COMPILE=mips64el-linux-gnuabi64-), the following error is produced when building the apps:

This is likely to impact us with automated builds when GitHub Actions switches their ubuntu-latest builder from 22.04 to 24.04 (and this issue was actually discovered when I tested some builds with GitHub Actions on their ubuntu-24.04 builder).

I'm not a big cross compiler.. but I tried and ran into a different issue.

include

Looks like missing glibc-headers

pbatard commented 1 month ago

I'm not seeing this on my platform.

It does look like you invoked the build with a different tuple than what I tested with though: make ARCH=mips64 CROSS_COMPILE=mips64el-linux-gnuabi64- vs make ARCH=mips64 CROSS_COMPILE=mips64-linux-gnu-.

You may want to reinstall the MIP64 toolchain with apt install gcc-mips64-linux-gnuabi64 and then try with the same tuple.

Yes, testing with a different distro - running on RHEL-9.1. I have glibc-headers.. for x86_64.. but not for mips64...

Should be the same (it's arch independent), looks like it's missing /usr/include from system header path, we could force include it using (-isystem)
