commit 369fdade93adf23ef3da3b5f8e9fcd14a2b3f093

Thanks for the report. When manually extracting the LLVM-4.0.1-win32.exe installer with 7-Zip 16.02:

7z.exe x LLVM-4.0.1-win32.exe

I obtain the following folders in the current directory:

'$PLUGINSDIR'
bin
include
lib
libexec
msbuild-bin
share
tools

with libclang.lib in the lib folder. Could you tell us which folders you are obtaining in your case?

micbou commented 7 years ago

And where the libclang.lib file can be found?

The reason has been found, the installation of lua5.1 with a low version of 7z.exe: 7-Zip 9.10 beta. It appears in the system's path environment variable, it is this version of the 7-zip caused the problem.

Another independently installed 7-zip version is 7-Zip [64] 16.02, able to correctly extract LLVM-4.0.1-win32.exe.

In the build, the use of the wrong 7-zip to extract, resulting in the problem.
