My problem is simple, or so it seems.
I want to compile the software SparForte from the source, here http://www.sparforte.com/downloads/sparforte-1.5.1-src.tar.bz2 . It is a shell and a JIT compiler for a script language wanted to be with the Ada language, once the code a tiny bit reworked.
I think I got all the dependances, yet, two annoyances appeared. First, the compile script don't see the command mysql_config, while it IS here. But let's forget, as I didn't need a database access from the shell or any script. For now, it's true enough, by the way. Second, way much graver : 'make' failed, because the file "/something/gst/gst.h" can't be found. But it is found by 'find / -name gst.h' here : /usr/include/gstreamer-0.10/gst/gst.h and /usr/include/gstreamer-1.0/gst/gst.h
the configure script was intended to work with gmake, so I've used, as hinted, the ' --make=make' option. But after it was just 'make all' or 'make'.
So, for heaven's sake, what happened ? I precise I am in root while doing all of that. I don't care for security.
