Clang compilation broken - Win32, MinGW 4.6

Clang Frontend
1

Hi,

I am trying to compile LLVM+Clang on WinXp using MinGW 4.6.

The compilation throws this error.

C:\llvm\tools\clang\include/clang/AST/Attr.h:112:31: fatal error: clang/AST/Attrs.inc: No such file or directory

The “clang/AST/Attrs.inc” does not exists at SVN revision 112179.

Here is an extract of the compilation.

This looks like a dependency issue in the CMake files. Attrs.inc is automatically generated by tblgen. Make sure that your LLVM is up-to-date and try rebuilding. If you can find the missing dependency in CMake, that would be great, too :slight_smile:

Thanks Doug,

I have an up-to-date revision.
I will try to find the missing dependency.

I have the same problem with the trunk.. 2 or 3 weeks ago I did a
complete llvm-clang build using MinGW and it worked 100%

I think that I got the problem. It is mi first time on clang sources. I am working on it.
Let me time!!! :slight_smile:

Fernando.

People,

I got the patch, but I can see that it have different formant than yours.
I am using TortoiseSVN.
What I’m wrong?

Fernando.

The patch looks great to me, thanks! Committed as r112261.

It did come through as an inline attachment rather than a separate attachment, which makes it a little hard to work with, but that doesn’t matter for small changes.

The comment in the log was written by hand. The rest is automatically generated by the script that reports all Subversion commits to the mailing list.
