Sun Studio 12 iropt problem
Hi, I am using Sun Studio 12 C++ compiler on my 64-bit Gentoo with AMD Turion64. So far everything seems to work fine except of IPO. Any attempt to compile even a simple code with -xipo > 0 causes this error:
compiler(iropt) error:Unexpected File IO error when reading IR.
/opt/sunstudio12/prod/bin/ipo: Error inside /usr/local/sunstudio12/prod/bin/iropt
It happens during the linking phase. strace shows that iropt dies just like this. I guess this is problem of incompatibility between linker in RH and Gentoo (the same options work fine on RH 32-bit and 64-bit). Any ideas how to deal with this problem (except of not using IPO)?
Thanks!

I had similar problems with express-2/3.
The 'ipo' executable had /usr/bin/b[un]zip2 hardcoded,
while on Gentoo they are in /bin directory.
To my knowledge, the problem still persists
in Studio-12.
The workaround was/is simple :
ln -s /bin/bzip2 /usr/bin/bzip2
ln -s /bin/bunzip2 /usr/bin/bunzip2
Alternatively, you may want to binary edit
file: [install_dir]/sunstudio12/prod/bin/ipo
and correct the hardcoded strings at
offsets : 68097 and 68186
