Hi All, I am working on a project to switch our gcc compiler from version 3.4.6 to 4.4.5. Our current build machines have 3.4.6 as the default c++ compiler and we installed 4.4.5 at a different location (/apps/gcc/......). The new installation of 4.4.5 comes with its own set of c++ headers and libstdc++, thus when I try to run the app built with the newer version of the compiler it does not run. I know one way to get this to work is to update libstdc++ on the system or set LD_LIBRARY_PATH to use the newer libs. I am wondering if it is some how possible to get 4.4.5 to use the old headers and libstdc++? Thanks in advance, Mandeep Deol
