A long time ago we have developed some software for a system with redhat 6.0. Our development server was also based on RedHat 6.0. A couple of weeks a go we switched to a new development server (dual opteron - 64 bit). the software still compiles fine, but offcourse does not work on the redhat 6.0 based systems any more. I want to be able to use the latest gcc compiler and compile my software with the old libraries (glibc, libstdc++ etc) of the redhat 6.0 based system. I keep getting linker errors. Does someone know a good link with a howto. Is it possible this way or do i need an old compiler version? Thanks in advance. Best regards, Patrick.
