Re: [ANNOUNCE] FisicaLab 0.3.5 release

[Fred Kiefer]

Congratulation for releasing another version of FisicaLab and this time
with video documentation. This will make it easier to start off using
this software.

I tried myself and already failed at using the configure script. There
you have an explicit path name for GNUstep gui and of course it is
installed in a different place for me. Your code reads like this:

   GUI_VERSION=`grep --recursive --no-filename
GSBundleShortVersionString
/usr/GNUstep/Local/Library/Libraries/gnustep-gui/Versions/`

This hardcodes a specific file system layout. You could work around this
by using two calls to gnustep-config:

gnustep-config --installation-domain-for=gnustep-gui

gnustep-config --variable=GNUSTEP_XXX_LIBRARY

Replacing XXX with the result of the first call. But all of this
wouldn't help either. In my case plenty of different version of gui are
installed in that directory

ls /usr/GNUstep/System/Library/Libraries/gnustep-gui/Versions/
0.17  0.19  0.21  0.23  0.24

And it seems unclear which of these your configuration code would choose.

I think you would be a lot better of by dropping this configuration
check and adding something in your source code that checks the values of
GNUSTEP_GUI_MAJOR_VERSION and GNUSTEP_GUI_MINOR_VERSION and prints out
an error or a warning:

#if GNUSTEP_GUI_MAJOR_VERSION == 0 && GNUSTEP_GUI_MINOR_VERSION < 23
#error "fisicalab requires at least gnustep-gui 0.23.0."
#endif

The good thing is that FisicaLab compiles correctly anyway,regardless of
that failed test in the configure file. Perhaps removing it is really
the best solution.
