Sorry, I have some more questions. I have added the AC_CONFIG_SUBDIRS macro in configure.in. In my case it looks like AC_CONFIG_SUBDIRS (kbiblio/btparse/configure) (my program is in subdir kbiblio, and the library is in sub-subdir btparse) Now, on ./configure, the configure script of the btparse package is called. So this works as expected. However, the files that the configure of btparse generates are written into the directory ./, not into the directory kbiblio/btparse/ :-(. So in summary, it doesn't work. Another problem arises in the make process. Adding btparse to the subdir line in the Makefile.am of kbiblio doesn't help to compile btparse, because automake is involved, which looks for a Makefile.in in btparse, which is not there because btparse build works differently from the kde-build process. So what I really need is the possibility to simply invoke the command make in the subdir kbiblio/btparse. Any ideas? Thank you very much, Claus (Getting this to run is very important to me, because it would give me BibTex parsing for free :-) ) -- Claus Wilke claus.wilke@gmx.net
