Hallo,
during winter vacation I had some fun building LFS again; I wanted to dive into UEFI systems. I installed Fedora 27 on a machine with an old-ish i5-3350, 16 GB RAM and 256 GB SSD. Fedora 27 comes with gcc 7.2, and this combination cannot build LFS 8.0 without changes. This information is obviously outdated because LFS 8.1 is out ;), but FYI here's why: gcc 7.2 is strictly conforming to the new ISO C/C++ standards and comes with some new constraints, both for syntax and semantics of source code. For some integer types you need to include the new <stdint.h>, and additionally it will choke on some code that previously was accepted. You cannot compile the LFS 8.0-included gcc 6.3.0, there's a change to ubsan.c required (if you still want to build 8.0 for some reason). src/gcc-6.3.0/gcc/ubsan.c: 1474:23: error: ISO C++ forbids comparison between pointer and integer [-fpermissive] fix is simple: - || xloc.file == '0' || xloc.file[0] == 'xff' + || xloc.file[0] == '0' || xloc.file[0] == 'xff' Tschau...Thomas -- "Do you wanna be a legend or a passing footprint on the sands of time?"
