I think you are heading down the wrong path. All of those error messages are normal. That’s just cmake doing feature detection, for example it will test whether your system has pthread.h by compiling a program that includes that header. So an error in your log about is missing pthread.h just means it will set HAVE_PTHREAD_H to false which is fine.<br><br>I’m confused why we’re talking about gcc and libomp if you’re trying to do a Windows build. You should just use msvc to build it. You don’t need any of the things you mentioned to do a build.<br><br>I still haven’t seen the output from cmake (just a paste of stdout). That’s going to tell you the real problem. The pog files I don’t think are very useful and will just lead you in the wrong direction.<br><br>You said you’re using cmake gui, maybe the problem is that the gui can’t find the Visual Studio installation. Did you run vcvarsall first? Try first running vcvarsall from a command prompt and tgen running cmake (command line or gui) from that same command prompt<br><div class="gmail_quote"><div dir="ltr">On Thu, Nov 29, 2018 at 7:55 AM Osman Zakir via llvm-dev <<a href="mailto:llvm-dev@lists.llvm.org">llvm-dev@lists.llvm.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div dir="ltr">I checked your CMakeError.log again. The .h include files it is marking as missing are not LLVM include files, but are OS-related (e.g., malloc/malloc.h), and in some cases appear to be potentially Linux ones (dlfcn.h, sys/ioctl, malloc_np.h).
I can't imagine why your build might be looking for Linux as opposed to Windows include files. That could be a clue to your problem.
<div><br>
</div>
<div>You said you installed the latest version of GCC before this attempt. This confuses me further, since you are using Visual Studio to build with, and that makes no use of GCC. In fact, honestly I am wondering if your GCC implementation libraries are somehow
in your search path wrt environment variables, and your build is actually trying to use the GNU/Linux header files rather than the VS Windows header files, which would certainly blow it up. Again, I am no expert here, so I don't have a definite answer, but
based on what little I know, this setup doesn't sound safe. Maybe get rid of GCC completely, as I am not sure when/how you would even use it on the Windows side.</div>
<div><br>
</div>
<div>Similarly, I don't believe Perl has anything to do with this either, as neither CMake nor VS make any use of it. But I can't imagine it causing any problems for you to have it.</div>
<div><br>
</div>
<div>I don't know anything about <span style="color:rgb(0,0,0);font-family:Calibri,Helvetica,sans-serif;font-size:16px">Backtrace, Libomp, Compiler-RT, so I cannot help you there. As we have discussed before, the source for clang and lld go into the llvm
source folder's "tools" folder by those names. If they are there, after the configure step of the CMake-Gui, options will automatically appear for both clang and lld. You will want to mouse click the checkbox next to CLANG_BUILD_TOOLS and LLD_BUILD_TOOLS prior
to hitting the generate button.</span></div>
