Hi, I have obtained a set of open-source programs from http://petertoft.dk/PhD/Recon2D.tar.gz uncompressed, etc, and it all goes through fine. When I compile, the programs work fine on my old 32-bit machine (results make sense), however there is a segmentation fault on my 64-bit laptop. I compile using: gcc -c -I../include -O3 -finline-functions -Winline -Wall -falign-loops=2 -falign-jumps=2 -falign-functions=2 -Wstrict-prototypes ..... (Note that I had to fix the makefiles in there.) Btw, I don't know if this could have anything to do with it, but this set of programs were written in 1996 (when 64-bit probably did not even exist at all). Also, all the code uses single-precision (floats) rather than my preferred doubles. (Which makes me ask: is it possible to go into all the many files and convert all the floats into doubles using some command? ) Many thanks, Ranjan ____________________________________________________________ FREE 3D EARTH SCREENSAVER - Watch the Earth right on your desktop!
