Hi all, I've been using the library in a computer with gcc 3.4.4 and boost 1.32 (in knoppix). I'm interested on uBLAS. The problem is that I need my code working in a different machine (robot) with gcc 3.4.1 in RH9. I've proved 1.30 (which generates a warning becouse gcc version is unknown) and 1.31 versions and there are problems when a matrix is resized. The values of the matrix are moved from their original positions. Also I have problems with zero_vector. Are there some difference between boost library versions? Could I do something to fix that problem?. Do I need to install gcc 3.4.4?. I've seen that gcc 3.4.4 is tested for uBLAS.
