[llvm-dev] llvm-6.0.0rc2: fatal error: clang/Basic/Version.h: No such file or directory

Thu Feb 15 06:45:55 PST 2018

Hi,

today I've tried to build llvm-6.0.0rc2 using Cmake on my "SUSE Linux
Enterprise Server 12.3 (x86_64)" with the following commands (gcc-6.4.0
is necessary for CUDA-9.0).

wget http://prereleases.llvm.org/6.0.0/rc2/llvm-6.0.0rc2.src.tar.xz

Unfortunately, I get the following error, although the missing file is
available.

Is it necessary to unpack the archives in different directories or to set
some environment variables or symbolic links so that Version.h will be found?
Thank you very much for any help in advance.

Kind regards
