I am using the macro AM_PATH_XML2(2.5.0) in my configure.ac which works
fine provided the libxml2-devel package is installed. But when this
package is not installed, I get errors:
aclocal
configure.in:62: warning: macro `AM_PATH_XML2' not found in library
autoheader
automake
autoconf
configure.in:62: error: possibly undefined macro: AM_PATH_XML2
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
So, it looks like I can not use AM_PATH_XML2 before installing
libxml2-devel, so I can not test if it is installed :(
I think I can try the following workarounds:
a) Copy the contents of AM_PATH_XML2 to my acinclude.m4 and redistribute it
b) Create a customized test that checks if AM_PATH_XML2 is installed
But I don't like any of them. I would prefer to have something in
autoconf like
if EXISTS_MACRO( [AM_PATH_XML2] ) ; then
Does anything like this exists yet?
Thanks a lot
