Hi there: I installed gcc3.3.6 in Fedora core 5 in order to make some legacy c++ programs to work. The commands of 'configure' and 'make strap' went smoothly except there are lots of warnings about types. My legacy program also worked after I 'make install' and prepended the paths of gcc3.3.6 to PATH and LD_LIBRARY_PATH. However, every time I use 'man' for some command, the following error occured: ------------------------------------------------------------ /usr/bin/gtbl: /usr/local/samPacks/gcc-3.3.6/lib/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6) ------------------------------------------------------------ I am very confused because if I switch to GCC4.1.0 that comes with Fedora Core 5, there are no such errors. Also, the current version is GCC4.1.1, where does this `GCC_4.2.0' come from? Any suggestions for solving this? I really appreciate your help!! Thanks and have a nice day! Qinghai
