llvm dev - Apr 2006 - [LLVMdev] Building LLVM under Mingw. Part I: tools-only

;) Well. Maybe this library will be included in some next versions of
mingw's win32api package. Anyway, we can make such library just
"on-fly" from the corresponding .dll.

JC> This is what's already there.  What changed?
Maybe this was my bug while trying to remeber, what I've patched ;)

BTW: I've also had to make this change when building tools.
(I'm building right now and noticed that it doesn't come up anymore,
maybe
someone checked it in in the last week or so)

So I've been continuing to work on building LLVM under Mingw.
I've made progress on the CFE build and will perhaps post my results later
today.

Anyway, I just did the tools-only part and had a few questions/comments

First of all, with regards to my setup. I have the following in my notes:

   These are the files I downloaded:
      MinGW-3.1.0-1.exe
      MSYS-1.0.11-2004.04.30-1.exe
      msysDTK-1.0.1.exe (for CVS)
      gcc-core-3.4.2-20040916-1.tar.gz
      gcc-g++-3.4.2-20040916-1.tar.gz
      binutils-2.16.91-20060119-1.tar.gz

      WARNING: llvm-tools wouldn't link with this version of gcc:
            gcc-core-3.4.5-20060117-1.tar.gz
	    gcc-g++-3.4.5-200600117-1.tar.gz

It seems like I had problems with gcc version 3.4.5. But I guess others
didn't see these problems? (I'll have to try it again).

Previously, I was patching X86JITInfo.cpp like this:

   NOTE: I couldn't get llc to link until I made the following change (CVS
diff):
	 Greg Pettyjohn at GREGLAPTOP ~/llvm/lib/Target/X86
	 $ cvs diff X86JITInfo.cppIndex: X86JITInfo.cpp

==================================================================	 RCS file:
/var/cvs/llvm/llvm/lib/Target/X86/X86JITInfo.cpp,v
	 retrieving revision 1.15
	 diff -r1.15 X86JITInfo.cpp
	 51c51
	 < #if defined(__CYGWIN__) || defined(__APPLE__)
	 ---
	 > #if defined(__CYGWIN__) || defined(__MINGW32__) ||
defined(__APPLE__)
	 62c62
	 < #if defined(__CYGWIN__) || defined(__APPLE__)
	 ---
	 > #if defined(__CYGWIN__) || defined(__MINGW32__) ||
defined(__APPLE__)

I noticed that this is no longer necessary in the CVS version, but I had
to do it on the 1.7 tarball version.


I've also been seeing the assertion while linking lc. I've seen it in
both
Mingw and similar behavior in cygwin. But I didn't see it in my most
recent build.

After running the tools-only build, I do a make install.
It chugs along just fine until it gets to the docs and then errors out on
the command guide:

make[2]: *** [install-local] Error 1
make[2]: Leaving directory `/home/llvm_home/llvm-build/docs/CommandGuide'
make[1]: *** [install] Error 1
make[1]: Leaving directory `/home/llvm_home/llvm-build/docs'
make: *** [install] Error 1

I've been assuming that since it has already installed the tools into my
PREFIX directory, that this is OK. Am I OK to ignore this?

So far this list has been very helpful. I'm thankful to see that some
others have decided to do a Mingw build.

Thanks.
