[LLVMdev] LLVMdev Digest, Vol 61, Issue 25

[Lance de La Haye]

Hi Anton,

The problem is in getting the system configured. Below is the crash I get in 
configure. Your comment regarding gnuwin32 not being needed is interesting - 
I actually installed gnu bison/flex to get past an earlier crash in 
configure.

Thats why I was suggesting that a precompiled OBJ_ROOT for MingW32 would be 
a good idea - configure appears to be inherently fragile, and requires more 
expertise than I have to get past it if it does fail.

Configure looking like a fragile thing, and windows programmers (like 
myself) lacking unix expertise to work arround it if it fails - the 
configure script is 1MB in size - 36000+ lines - which is pretty daunting.

I am getting the exact same crash for the configure script for libjit as 
well by the way, so I know it's my fault. But I'm not sure whats broken. Do 
I have a bad version of 'sed' or something?

I am already using MinGW for my own work, so my basic configuration works 
well enough. I installed msys1.0 so I could build llvm, but have no other 
need for it. If I could get at a pre-built OBJ_ROOT, I still wouldn't need 
it I believe.

NB: The configure script for libjit is 800K

=============================================================
This is what I get when I run configure or make.
