Hi,

Host : Ubuntu 18.04.3 LTS
GCC : gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0
uname : Linux vm 5.0.0-27-generic #28~18.04.1-Ubuntu SMP Thu Aug 22 03:00:32 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I have clone the GRUB2 from https://github.com/rhboot/grub2 today and the HEAD points to e7b8856f8be3292afdb38d2e8c70ad8d62a61e10 (linux: Fix integer overflows in initrd size handling).

I followed the below steps to compile after cloning :
$ ./bootstrap
$ ./autogen.sh

$ export EFI_ARCH=x86_64

$ ./configure --with-platform=efi --target=$EFI_ARCH --program-prefix=""

$ make


I get the below error :


Making all in grub-core

Hi,

I figured out that I should add "--disable-werror" to the configure.

After this I was able to build successfully.

Thanks,
Naveen

Hmm, interesting. I also compile on ubuntu (upgrade to 20.04) with no
added CFLAGS and do not have this problem.  In the configure, I see
detection for disabling PIE compiling/linking.

checking whether `gcc' has `-fPIE' as default... yes
checking whether linker accepts -no-pie... yes
checking whether linker accepts -nopie... no
checking whether linker needs disabling of PIE to work... no

And compiler options -fno-PIE and -fno-pie and linker option -no-pie
are used.

I don't think building with PIE is useful nor the norm for grub (maybe
I'm wrong?).  Do you have those configure lines?  Perhaps this is
related to your compiler version?  I'm using gcc version 9.3.0 (Ubuntu
9.3.0-10ubuntu2).

If you're doing development, perhaps you can use CFLAGS="-fno-PIE
-fno-pie" and LDFLAGS='-no-pie' instead of "--disable-werror".
