Re: [Gems-users] Compiling problems with transaction.c in Gems 2.0

[Jayaram Bobba <bobba@xxxxxxxxxxx>]

Ruben,

My guess is that this could be
- a bug in gnu assembler (gas) or
- a bug in gcc or
- bad inline assembly.

To rule out the first two cases, could you recompile with a different 
version of gcc / configured to use a different assembler (preferably 
'as'). We have
successfully compiled the TM workloads using the following gcc build...

Configured with: 
/gates/sfwnv/builds/sfwnv-gate/usr/src/cmd/gcc/gcc-3.4.3/configure 
--prefix=/usr/sfw --with-as=/usr/ccs/bin/as --without-gnu-as 
--with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++,f77 
--enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-20050802)

We have also had problems compiling with the following gcc setup (i 
think it uses 'gas')-
Target: sparc-sun-solaris2.10
Configured with: 
/export/home/bldmstr/nightly/20060207_gcc2ir.s10.opt.tarbuild/src/configure 
--prefix=/opt/gcc --enable-languages=c,c++
Thread model: posix
gcc version 4.0.2 (gccfss)
