Hello, I successfully built llvm by hand after trying to do so with ALFS-svn checkout on the Sunday 1st of April with both LFS and BLFS checked out on the same date. The ALFS logs for llvm show this issue:
In file included from /sources/llvm/llvm-6.0.0.src/build/include/llvm/Support/DataTypes.h:33:0, from /sources/llvm/llvm-6.0.0.src/include/llvm/Support/SwapByteOrder.h:19, from /sources/llvm/llvm-6.0.0.src/include/llvm/Support/MathExtras.h:18, from /sources/llvm/llvm-6.0.0.src/include/llvm/ADT/APInt.h:20, from /sources/llvm/llvm-6.0.0.src/include/llvm/ADT/APFloat.h:20, from /sources/llvm/llvm-6.0.0.src/lib/Support/APFloat.cpp:15: /usr/include/c++/7.3.0/cmath:45:15: erreur fatale: math.h : Aucun fichier ou dossier de ce type #include_next <math.h> The error repeat over many files and is at the start of llvm compilation after running cmake. The hand built version compiled successfully so I'm suspecting an issue with the environment variables within ALFS making gcc trip up. Finally, the hand build version was run with stdout and stderr redirected to files and both files I can upload somewhere for closer examination on request. Command used was: make 1>../../compile.log 2>../../error.log The end goal is to build an usb key ramdrive image containing X, lxqt, qupzilla and thunderbird which will be used to bootstrap other system and still be able to carry out work while the system is bootstrapping.
