I am new to Linux, but I am invsetigating a performance issue in a big tomography program developed for Windows. We have made a command line version of this and compiled for 64 bit architecture on Win X64 to evaluate performance improvements. The compilation was done in WinXP (32 bit) using MS VisualStudio 2005 but targeting X64. The questions now are: 1) Is it possible to cross-compile on Linux 32 bit to produce an executable for the 64bit architecture Linux as well as 32 bit? 2) Can we expect an improvement in performance of such a command line (no GUI) program in Linux compared to Windows? The program performs massive math calculations and has been optimized to use the available resources well. 3) The program is written in C++, would there be big porting issues moving it from Windows to Linux, code-wise? I understand that this is not a Fedora question per se, but since Fedora is such a popular distribution I thought that the comparison and development questions may fit here anyway. Sorry if you all disagree... Grateful for any comment though. Bo Berglund
