GCC 10 will enable -fno-common by default. It would break some "legacy" (actually buggy IMO) code. I found some cases in the book with GCC 9 and -fno- common explicitly enabled.
Patches uploaded to http://www.linuxfromscratch.org/~xry111/fno-common-patches/. I hope the upstream can fix these cases before GCC 10 (for SDL2, xorg-server and pipewire the fix is already commited). But if they don't we can grab these patches as needed. -- Xi Ruoyao <[email protected]> School of Aerospace Science and Technology, Xidian University -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
