I'm trying to compile the top version of LLVM with MinGW, but I'm
getting compilation errors.
They seem to be caused by the changes in rev 66072. Has anyone
compiled on MinGW?
Since I just installed MinGW on this computer it could be my problem.
(I noticed that LLVM 2.5 still doesn't come with binaries for the
libraries on MinGW.)

What kind of errors?
Ciao,
Duncan.
Like this:

The void sys::AddSignalHandler() is outside the llvm namespace, which
seems wrong.
Moving it inside removes the first errors, but still leave KillSigs,
KillSigsEnd, and RegisterHandler undefined.
If I didn't know better I'd think someone had committed code without
compiling first.

Please try r66386.
If I didn't know better I'd think someone had committed code without
compiling first.
I don't have a windows box to test on, I requested windows people to verify that it works when I committed the change, and there are no windows nightly testers or build bots. This is the first I have heard of the breakage.

I know, it's a pain to develop for multiple platforms.
Anyway, r66388 works better. It compiles for quite a while, and then
dies linking Hello:

undefined references.

Commenting out the Hello transformation I get these link errors:

It seems that dbghelp.lib is required for building this.
Which build generator system are you using? cmake or configure?
[snip]
I'm using configure.
Just disable both libhello & liblto - they won't be usable on windows at all.
I'll take care on mingw build pretty soon.
