[epiar-devel] [configure error]: Is xml2-config in path?

[Christopher Thielen]

  A quick primer on the GNU autotools system. One writes the 
configure.in file which is used to generate the configure script 
(generated by one of the 4-5 simple commands in autogen.sh).

If you can confirm /usr/bin/xml2-config is working, then you've got some 
kind of interesting problem ...

You'll notice in configure.in there's something about libxml2, probably 
a single line that says AC_MACRO(LIBXML2) or something similar. What 
this does is reference a GNU autotools "macro" that was installed by 
libxml2. Various Linux libraries install these macros so developers like 
us can call them in our configure scripts -- essentially letting the 
authors of libxml2 or whatever library write their own installation 
checks so we don't have to (and they should be the ones to write it 
anyway!).

First, check that you have a libxml2-dev or something similar installed. 
Maybe you're missing the dev package (not likely since xml2-config is 
there but check anyway). Rather than that, you can 'brute force' the 
libxml2 config by deleting the macro line in configure.in and taking the 
output of:

xml2-config --cflags

and

xml2-config --libs

and manually inserting them into the CFLAGS and LIBS variables in 
configure.in.

I know that's a dirty solution and I'm throwing you ruthlessly into the 
world of GNU autotools but once you're used to it, it's a very handy 
tool, especially given it's wide usage in the Linux/FLOSS world.
