Hi everybody, Just thought it would make more sense to reply directly to my original thread since I am still experiencing the same issue as before.
I took the aforementioned advice and followed Thomas's steps for building a multilib LFS system using his most recent 20191207 release with only one variant-- I am using systemd instead of SysvInit. So far, I have not encountered any issues with any packages in the LFS book or using the stable BLFS-9.0-systemd book. However, much like before, I installed LLVM with no build errors before moving on to try and install ICU-64.2 (and then I tried ICU-65.1 with same result). Again, I receive the exact same error message during the configure step: *checking if we have a C++ compiler... no* *configure: error: C++ compiler clang++ does not work or no compiler found* Here are the outputs of a few commands I tried to ensure clang++ was in fact installed on the system: *$ which clang++* */usr/bin/clang++* *$ ldd /usr/bin/clang++* * linux-vdso.so.1 (0x00007ffe575b4000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f91e7448000) libLLVM-8.so => /usr/bin/../lib/libLLVM-8.so (0x00007f91e439c000) libstdc++.so.6 => /usr/bin/../lib/libstdc++.so.6 (0x00007f91e41bc000) libm.so.6 => /lib/libm.so.6 (0x00007f91e4077000) libgcc_s.so.1 => /usr/bin/../lib/libgcc_s.so.1 (0x00007f91e405d000) libc.so.6 => /lib/libc.so.6 (0x00007f91e3e99000) /lib64/ld-linux-x86-64.so.2 (0x00007f91e7475000) libffi.so.7 => /usr/bin/../lib/../lib/libffi.so.7 (0x00007f91e3e8a000) libz.so.1 => /lib/libz.so.1 (0x00007f91e3e6d000) librt.so.1 => /lib/librt.so.1 (0x00007f91e3e63000) libdl.so.2 => /lib/libdl.so.2 (0x00007f91e3e5e000) libncursesw.so.6 => /lib/libncursesw.so.6 (0x00007f91e3def000) libxml2.so.2 => /usr/bin/../lib/../lib/libxml2.so.2 (0x00007f91e3c89000) liblzma.so.5 => /lib/liblzma.so.5 (0x00007f91e3c5f000)* I have no clue what the issue could be or if the issue is related with the build of LLVM messing up somewhere or simply with ICU. I would simply try installing ICU with the GCC compiler instead if it weren't for the fact that both 64.2 and 65.1 versions of ICU fail to detect clang++. This makes me think something messed up in LLVM. If indeed something is messed up with LLVM, I'm afraid I don't have the technical prowess to figure out what that could be since no error message is given throughout the LLVM build process from what I could see. Thanks, -- Jared
