When I try to use boost on an old Linux system, I get the message:
Compiler not configured - please reconfigure
The version of my gcc is:
gcc version 2.9-gnupro-99r1
And in boost's gcc.hpp file I see:
// versions check:
// we don't know gcc prior to version 2.90:
#if (__GNUC__ == 2) && (__GNUC_MINOR__ < 90)
# error "Compiler not configured - please reconfigure"
#endif
So, are gcc 2.9 and 2.90 actually the same thing? If yes - can I just update the gcc.hpp? And if not, how can I still use boost?
EDIT:
I actually tried to change (__GNUC_MINOR__ < 90) to (__GNUC_MINOR__ < 9).
Seems like 2.9 and 2.90 are not the same because now I get compilation errors.
Seems like the errors are because this compiler doesn't support the \ (line extension) characters in the preprocessor macros. These line breaks are used by boost in many places.
If you can't upgrade the compiler, downgrade the sources. Not really very sensible advice, but still, it might work.
Old Boost releases are found here: http://sourceforge.net/projects/boost/files/
Good luck!
PS: if it's the line breaks that are killing you, maybe you can try to remove them (if there aren't too many)
