Way to use g++2.96 lib in g++3.x compiled app?
Wed Dec 3 20:45:00 GMT 2003
The folks at Lizard Tech have a g++ 2.96 compiled library for decoding
the MrSID image format. I emailed them about getting a g++ 3.3 compiled
library instead and they blew me off.
Anyways, this doesn't fix my problem of having to integrate this
library. I don't want to back port all my code just because of a stupid
My idea to get this to work is:
- Write a 'c' wrapper with the minimal functionality I need.
- Compile 'c' wrapper with g++ 2.96
- Resove the libstdc++ and MrSID library symbols in the 'c' wrapper
using g++ 2.96.
This should leave only 'c' compatible symbols in the wrapper .o file.
I've already written the 'c' wrapper and can compile it no problem.
But what I don't know is how to selectively resolve symbols from just
the 2.96 libstdc++ and MrSID libraries.
Can anyone point me to what options for ld (if any) or some other
binutils type utility that I could use to do this?
Or am I just plain SOL?
