Re: [Gimp-developer] Gimp "make install" fails with undefined references to fresh-built gegl

I got all of the dependencies (except WebKit) and GIMP 2.10.20 to build on
CentOS.
To make a very long  story short, each dependency, and GIMP, is best built
with no traces of previous builds or out-of-date dependencies. "make clean"
and re-configuring  are inadequate. It's easiest just to re-clone each
repository, or delete each extracted source directory.
Each dependency needs to be installed into whatever build-prefix is
configured, and then the next dependency may be built. Sometimes, Iterating
over multiple versions of a dependency is required. In that case,
delete/uninstall the older version after you have built what needed it, and
then build the newer version.

I simply gave up for webkit. Webkit is gigantic, and has a wilderness of
dependencies. It easier just to use an external browser to access GIMP help.

Subject: [Gimp-developer] Gimp "make install" fails with undefined
references to fresh-built gegl

I built gimp 2.10.18 on CentOS 7 last year on another host, but on a new
host with gimp 2.10.20, I'm stuck with undefined reference errors for GEGL.
I'm not a c++ developer, so this is all a foreign language to me :(

 

CentOS 7 libraries are all very old, so I built them, including latest GEGL
(0.4_24) and configured it with -prefix=/opt/gimp2.10

I deleted all gegl files before rebuilding, and now when I look in the lib64
dir I see the new libs:

 

ls -1 /opt/gimp-2.10/lib64/libgegl-* 
        /opt/gimp-2.10/lib64/libgegl-0.4.so
        /opt/gimp-2.10/lib64/libgegl-0.4.so.0
        /opt/gimp-2.10/lib64/libgegl-0.4.so.0.424.1
        /opt/gimp-2.10/lib64/libgegl-npd-0.4.so
        /opt/gimp-2.10/lib64/libgegl-sc-0.4.so

 

ls -1 /opt/gimp-2.10/lib64/pkgconfig/gegl-*
        /opt/gimp-2.10/lib64/pkgconfig/gegl-0.4.pc
        /opt/gimp-2.10/lib64/pkgconfig/gegl-sc-0.4.pc

 

I set LD_LIBRARY_PATH and PKG_CONFIG_PATH to include my fresh libraries:

 
LD_LIBRARY_PATH=/opt/gimp-2.10/lib64:/opt/gimp-2.10/lib:/usr/local/lib64:/us
r/local/lib:/usr/lib
 
PKG_CONFIG_PATH=/opt/gimp-2.10/lib64/pkgconfig:/opt/gimp-2.10/share/pkgconfi
g:/opt/gimp-2.10/lib/pkgconfig/pkgconfig:/usr/local/share/pkgconfig:/usr/loc
al/lib/pkgconfig

 

But when I try to build gimp, ld fails. The errors start with:

 

make[3]: Entering directory
'/usr/exports/projects/3rd_party/gimp-world/gimp/app'

CCLD gimp-2.10

display/libappdisplay.a(gimpdisplay.o): In function
`gimp_display_update_bounding_box':

gimpdisplay.c:(.text+0x130c): undefined reference to
`gegl_rectangle_subtract'

...

gimp-gegl-utils.c:(.text+0xc7e): undefined reference to
`gegl_rectangle_subtract'

collect2: error: ld returned 1 exit status

make[3]: *** [Makefile:1010: gimp-2.10] Error 1

...

 

Is this a gegl mis-configuration or a gimp one?

How should I fix?

 

Thanks!
