Hi,
When configuring on a Solaris 11.4 system I get in 'configure'
checking for PangoCairo libraries... no
******** disabling UnicodePlugin
However pango is installed on Solaris 11.4 :
library/desktop/pango 1.40.4-11.4.0.0.1.14.0 i--
on Solaris 11.3 I have
library/desktop/pango 1.40.4-0.175.3.29.0.3.0 i--
And on Solaris 11.3, the UnicodePlugin compiles and is not disabled.
I think this is related to an issue in the Makefile.inc and configure script.
The configure script is doing a small test with
CPPFLAGS="-I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/lib/arm-linux-gnueabihf/glib-2.0/include -I/usr/lib/i386-linux-gnu/glib-2.0/include"
cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h. */
#include <pango/pangocairo.h>
But the above includes are wrong for Solaris 11.4
For the UnicodePlugin, I've noticed that
platforms/unix/plugins/UnicodePlugin
has two files Makefile.inc and acinclude.m4 (which are possibly related,
by autoconf) that have
XCPPFLAGS= -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/lib/arm-linux-gnueabihf/glib-2.0/include -I/usr/lib/i386-linux-gnu/glib-2.0/include
Note that on Solaris 64bit I think the above is not correct.
On Solaris there is:
# pkg-config --cflags glib-2.0
-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
and
# PKG_CONFIG_PATH=/usr/lib/64/pkgconfig pkg-config --cflags glib-2.0
- -I/usr/include/glib-2.0 -I/usr/lib/amd64/glib-2.0/include
It should somehow include /usr/lib/amd64/glib-2.0/include/ for the Makefile,
and also for the configure script, in the case of a 64 bit build.
So the arm-linux-gnueabihf and i386-linux-gnu stuff is wrong and not needed.
When changing the Makefile.inc to delete the -I/usr/lib/arm-linux-gnueabihf/glib-2.0/include -I/usr/lib/i386-linux-gnu/glib-2.0/include stuff, and add the /usr/lib/amd64/glib-2.0/include this is fixed.
I can also change the 'configure' script and fix the include.
The right fix probably is to regenerate it with 'autoconf' but this requires,
perhaps to have it use the pkg-config --cflags output ?
Also instead of changing Makefile.inc, maybe some trick is
possible to have it use the pkg-config --cflags output ??
Note that for some reason on older versions of Solaris like Solaris 10
and Solaris 11.3, the issue is not happening,
but the includes are still wrong. They just don't break the build there.
Regards,
David Stes
