Re: [Swarm-Support] Installation on Linux Fedora Core 4

[Paul Johnson]

I posted RPMS for this a while ago.

http://lark.cc.ku.edu/~pauljohn/Swarm/Swarm-2.2X_Fdr4/

Please be warned that the blt in Fedora Extras is not adequate and you 
really do need the one I offer. HDF5 from extras is OK.

My SPEC file applies some patches, the consistentCasts patches I 
mentioned in here about 5 months ago, and also fixes for these FC4 
related problems.

Here's a patch that fixes the signedness problem you mention

diff -rc swarm-2.2-orig/libobjc/mframe.m swarm-2.2/libobjc/mframe.m

! getSizeAndAlignment(const char *typePtr, unsigned *sizep, unsigned 
*alignp)
  {
    NSArgumentInfo        info;
    typePtr = mframe_next_arg(typePtr, &info);
--- 1570,1579 ----
    objc_free(argframe);
  }

  static void
! getSizeAndAlignment(const char *typePtr, int *sizep, unsigned *alignp)
  {
    NSArgumentInfo        info;
    typePtr = mframe_next_arg(typePtr, &info);



After  you fix that signedness problem, and try to compile, you will 
come to some code that uses an inline function that depends on variable 
length arrays and the compile will fail there too, and the only fix I 
found was to comment-out support for unions in mframe. In the mframe 
code, you'll see a place where ther is a definition that depends on 
CHECKER.  This issue with gcc4 has been reported on the redhat bugzilla 
and I'm assured by several experts that they are aware and trying to fix it.

I just chickened out and commented out the whole section because it was 
fastest for me...
