Dear all, Perhaps slightly off topic but...
I compiled and installed gcc-3.0.4 in /usr/local/gcc-3.0.4 then did export PATH=/usr/local/gcc-3.0.4/bin:$PATH export LD_LIBRARY_PATH=/usr/local/gcc-3.0.4/lib:$LD_LIBRARY_PATH after which I did ./configure in the lyx dir. But then I get this checking whether the C++ compiler (../../gcc-3.0.4/bin/g++ ) works... no configure: error: installation or configuration problem: C++ compiler cannot create executables. configure: error: ./configure failed for sigc++ but a small hello world program compiles fine: g++ hello.C -o hello ldd hello libstdc++.so.3 => /usr/local/gcc-3.0.4/lib/libstdc++.so.3 (0x40018000) libm.so.6 => /lib/i686/libm.so.6 (0x400c0000) libgcc_s.so.1 => /usr/local/gcc-3.0.4/lib/libgcc_s.so.1 (0x400e3000) libc.so.6 => /lib/i686/libc.so.6 (0x400eb000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) Tips from the computer literate are greatly appreciated. Thanks, Ed.
