OK, First of all: I'm from Romania and because I'm speaking a Latin language too, there's no problem for me to understand some basic Spanish, so it's just ok with the command line... ;) Yes, I've used konsole and I think I've choose IceWM-English from KDM. Second: As I read on the INSTALL file of AMS source, you just have to edit the Makefile for the paths and then just use make to get the binaries. There's no configure (or maybe it's just my confusion - I'm not an advanced Linux user). I've attached the whole error message, which is quit long so I didn't past it all on my last reply. I think it would be better, if it's not too much trouble for you, to get the AMS source and inspect the files and maybe to try to install it to see if we get the same result. http://sourceforge.net/project/showfiles.php?group_id=69130 PS: The main issue (which makes the spectrum view to not work) is that at the time when AMS was developed there was only a single version of the libfftw, using just float. Nowadays there are always two versions, one using float (sfftw/sfftw-dev) and one using doubles (fftw/fftw-dev). So, the wrong header files are picked up, and the float data from AMS is passed to the wrong functions (expecting double), resulting in garbage. The solution is to edit "spectrumscreen.cpp" (line 12) and " spectrumscreen.h" (line 15), and in both, change the #include <rfftw.h> to #include <srfftw.h> This is what I found out at the AMS mailing list. All the best, Marius
