I assume that a shared library is made using object files, in a similar way like a static library. Is there any extra requirements that need to be considered? > 2. Why do you include miniMOPAC?

In the app package, we also still have the built-in copy of OpenBabel. We could use it as a library as well, once OB's library support is ready. Or is it already? > 3. Did you consider using automake? Sorry, I'm not familiar with this either. Could you briefly explain what would be the benefits of automake? I'll shortly write an another mail as well where I explain some plans for v2.00 since it might relate to this question. > that pc file then gets installed in $(DESTDIR)$(libdir)/pkgconfig, so I > guess that could be anywhere you like. Yes, but it must be a place where pkg-config can find the file; I wondered whether it looks both /usr/lib/pkgconfig and /usr/local/lib/pkgconfig. > Well, gchemutils (gcu.pc) e.g. does it like you say above: > > prefix=@prefix@ > exec_prefix=@exec_prefix@ > libdir=@libdir@ > includedir=@includedir@ > > Name: GtkPeriodic > Description: A Mendeleiev table widget for GTK+-2.0 > Version: @VERSION@ > Requires: gtk+-2.0 > Libs: -L${libdir} @GCU_LIBS@ -lgtkperiodic -lgcu @gtkcrystalviewer@ > Cflags: -I${includedir}/gcu @GCU_CFLAGS@ @gl_flags@ Yep, the .pc files are short ones, about a dozen lines like the one above. I thought that perhaps the .pc file could be written in the configure script. I made a following test script: #! /bin/bash rm test.pc echo this is line 1 >> test.pc echo homedir = $HOME >> test.pc echo this is line 3 >> test.pc The script makes a test.pc file: this is line 1 homedir = /home/thassine this is line 3 And since the headers and libs already are stored in env variables in the script, it would be easy to write out a .pc file that contains the settings. It seems to be possible even to take the --enable-mpqc option out of ghemical script, and only keep and maintain it in libghemical script (at the moment there are still duplicates). Regards, Tommi
