Q - ./configure fails with the message Cannot find gagout in GILDAS libraries A - This means that Gildas libraries were not found on your system. If you did install them, please update the locate database by running sudo updatedb Alternatively, you can try specifying directly the path to the Gildas libraries to ./configure this way: ./configure -with-gildas-dir=/usr/local/gildas-exe-aug08a/lib where, the /usr/local/.../lib will have to be adapted to the actual location of the Gildas libraries. Q - Soas was compiled with Scalc, but it crashes complaining that Scalc cannot be found A - If you have installed Scalc, AND the output of ./configure said "configure: * Scalc: fits with arbitrary functions" AND soas crashes with the message that it can't find libscalc.so, then: as root, edit /etc/ld.so.conf, add the following line /usr/local/lib and run /sbin/ldconfig --- Q - GILDAS-feb08 was compiled with G95. When running ./configure it errors out while checking for a library containing gdf_fris. "configure: error: cannot find gdf_fris in GILDAS libraries" A - This problem was mysteriously solved by building SOAS with gfortran. --- Q - I have installed the mac version of SOAS. I can get neither GREG nor SOAS to work. I am using the X Window System XQuartz. (http://xquartz.macosforge.org/) A - Use XDarwin instead of XQuartz. It is available as an optional install ("X11") on the Mac OS X v10.3 Panther, and Mac OS X v10.4 Tiger install disks. http://developer.apple.com/Darwin/runningX11.html --- Q - configure errors out: configure: error: no suitable getcwd primitive found... A - This might be an issue with g95. Use recent versions of gfortran. gfortran-4.3 is known to compile and link correctly gildas libraries and soas. --- Q - I have installed Gildas from Feb '10. Soas (soas -ffGPES) starts fine, but then the problem starts. Only the 'l' and 'W' seem to give response. Even 'm' and 'h' give errors. When trying to load a data file it seems never to find the file and with 'W' I get a list of files in the directory and then and error saying that no temporary files can be made in this folder. A - Although it is possible to compile soas without the 'readline-dev' package, the generated executable will not actually be able to take any commands.
