Re: Compiler Errors

[Santhosh Edukulla <santhosh edukulla gmail com>]

Team,

We are using libxml++ and using below entries under Makefile.am as below:

If i dont include them, it throws tons of errors. As mentioned in
other mail to use pkg_config to g++ compiler directly works and  no
issues.

Question1: I wanted to know as how can i include pkg_config directly
under Makefile.am to avoid many includes below?

INCLUDES =  -I${includedir} -I${COMMON}/include
-I${top_srcdir}/appconfig/include
-I/usr/include/libxml++-2.6/libxml++/ -I/usr/include/libxml++-2.6
-I/usr/include/libxml++-2.6/libxml++/exceptions
-I/usr/include/libxml++-2.6/libxml++/parsers
-I/usr/include/libxml++-2.6/libxml++/validators
-I/usr/include/glibmm-2.4 -I/usr/include/glibmm-2.4/glibmm
-I/usr/include/glib-2.0 -I/usr/include/glib-2.0/glib
-I/usr/include/glib-2.0/include
-I${top_srcdir}/sysroot/usr/local/lib64/glib-2.0/include/
-I/usr/lib64/glibmm-2.4/include/ -I/usr/lib64/libxml++-2.6/include/

Question2: Also, we have made a static library which is written using
libxml++ lib. Now, this static library is used by various modules. Do
they also had to refer to pkg-config in their makefile.am to get the
module working? currently, when i have written a test program
consuming this static library, it throws those errors and only when
executed with pkg-config cflags...etc to g++ compiler, it works.

Any thoughts?

Thanks in Advance!
