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:
*

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,

Have you tried something like:
echo 'int main() { }' | clang++ -v -xc++ -
The output may contain some clue of what is happening
