Re: Library dependencies & make install

[Sander Niemeijer]

I second this. With our toolbox containing both modules and shared 
libraries we have stumbled upon this exact same problem. The modules 
needed to be linked against a shared library but automake was 
installing them before the shared library (which resulted in either 
linking against old libraries that were already installed, or in a 
linking failure). Our current solution is to link the .o files of the 
shared libraries in the modules via an internal library (we had to 
create an extra noinst_LTLIBRARIES target for this), but this results 
in a lot of big module files. I would therefore really welcome it if 
automake would gain support for installing libtool libraries in the 
appropriate order.
