OT: C programs and architectures (use on Fedora)

[Ranjan Maitra]

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
