Latest commit 3fc1b40 fails to compile with GCC 8.3.1 on Centos 7.9. about ipxe HOT 8 CLOSED

The R_X86_64_GOTPCRELX et al errors should be resolved by a trivial patch to elf2efi.c to add extra constants to the /* Provide constants missing on some platforms */ section. I'll push a PR for this later this evening, if I get time.

git reset --hard HEAD~2 prior to compiling removes the error messages and allows compilation to finish, so the problem been introduced since 337880d.

The failure to chainload turns out to be DNS not working so well in the building I'm in. Replacing chain tftp://server.domain/menu.ipxe with chain tftp://ipaddress/menu.ipxe solved that problem. The compilation failure remains outstanding.

Thanks for the report!

When was gcc 8.3 released?
If you need to build with old versions of gcc you might need to stay on older commits.
You should be able to use a Docker image or other VM with a never set of build tools to build current master.

It might be harder and harder to stay compatible, not sure how long back we really should (or must?) stay compatible?

https://gcc.gnu.org/gcc-8 says May 2019. The GCC shipped with my CentOS 7 system was 4.something, I had to use https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/ to get 8.3 and there isn't a later devtoolset release.

Would an iPXE compiled on an Ubuntu system work on a CentOS 7 server?

Would an iPXE compiled on an Ubuntu system work on a CentOS 7 server?

That's one of my stupider questions of today. Of course it will, because the laptop under build is executing the iPXE binary, not the server hosting it.

OK, this part at least should be solved in commit 9e92c3989 (and in wimboot in commit ipxe/wimboot@47f6298)

With the current master (commit 9e92c3989) I now get a successful build in a CentOS 7.9 container:

[root@7a3b91da0507 src]# cat /etc/redhat-release 
CentOS Linux release 7.9.2009 (Core)
[root@7a3b91da0507 src]# gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)
