>Why, exactly, do you need gcc-4.1? We have a simulator which is old. I can fix the compiler errors under gcc 4.4 for the code *itself*. However the code uses boost 1.33.1 and this version of boost won't compile on gcc4.4. Since I am not familiar with the complex structure of boost, at this time I have to find a way to *just* run the code.

Problem is, when I run a simple c++ code, I get a crash. I see you put it in /opt/. *Good*, keep it out of the dfault /usr/bin or /usr/local/bin locations. > #include <fstream> > using namespace std; > int main() > { > ofstream fout ("test.txt", fstream::out); > return 0; > } > > [mahmood@localhost ~]$ /opt/gcc-4.1.2-built/bin/g++ -g -ggdb -o test test.cpp > [mahmood@localhost ~]$ gdb test > GNU gdb (GDB) Red Hat Enterprise Linux (7.2-56.el6) > Copyright (C) 2010 Free Software Foundation, Inc. > ... > Reading symbols from /home/mahmood/test...done. > (gdb) r > Starting program: /home/mahmood/test > > Program received signal SIGSEGV, Segmentation fault. > 0x00000037e26f22d0 in ??

Now what I want to do is to install a package like > libgcc.x86_64 which supports g++-4.1. Good luck with that, it's a *lot* of work and likely to cause conflicts with tyour gcc-4.4 components. You can put them in /opt if you like. But why, exactly, do you want to do this? > I couldn't find "compat-libgcc.x86_64". > > Is there anyway to install libgcc-4.1? libgcc and compat-gcc-34 are built from gcc source code, as part of building up all of gcc. Why, exactly, do you need gcc-4.1?
