llvm dev - Feb 2007 - [LLVMdev] Building LLVM and LLVM-GCC4 on Cygwin

Hello,

Well theres not too much to it. A patch for Cygwin's stdint.h. And a patch
for lib/System/Unix/Program.inc.

Despite Cygwin complaining of timing errors both LLVM and LLVM-GCC4 compile
ok'ish.

    make[2]: Warning: File `/dev/null' has modification time 0.0096 s in the
future
    make[2]: warning:  Clock skew detected.  Your build may be incomplete. 

I am getting this on both XP and Vista and am writting to the Cygwin list
regarding this.

In Cygwin's 'include/stdint.h' int32_t and uint32_t have to be
changed from long's to int's.

        http://www.aarongray.org/LLVM/Patches/stdint.h.diff

The alternative is to add some disambiguation functions to LLVM, these would be
inline and transparent with no overhead.

And 'lib/System/Unix/Program.inc' has to have three lines #def'ed
out on the Cygwin build.

        http://www.aarongray.org/LLVM/Patches/Program.inc.diff

This is because Cygwin does not support RLIMIT_RSS.

There are 'make check' results here :-

        http://www.aarongray.org/LLVM/check.txt

The summary :-

  ===  Summary ==
    # of expected passes 1620
    # of unexpected failures         136
    # of unexpected successes         1
    # of expected failures 19

Pritty rag tailed quite a few complaits and it also ended with errors.

There are build instructions here :-

        http://www.aarongray.org/LLVM/BuildingLLVMonCygwin.html

Be aware with these timing errors Cygwin is not a solid development or build
platform at present.

Release build coming soon :)

Regards,

Aaron

This is invalidated as --enable-llvm switch was not included on the LLVM-GCC4
configuration. AND LLVM-GCC4 will not compile with GCC 3.4.4 (under Cygwin). :(
