Is this just me or is there a general problem?
It seems your extract is too short to tell something. Were the 2 dependencies correctly generated and installed ? Have you a full Slackware install (maybe without one or other desktop) ?
Since the routines which could not be linked had the namespace `testing::`, I added `-D2GEOM_TESTING=OFF` to the Slackbuild's cmake line. Using this modification, it build (and works) fine.
Not sure what the actual problem was, but since the tests are not run anyway, their building should probably be removed from the Slackbuild script anyway.
No, gtest is installed. I can also link arbitrary objects against it without any problem (so the linker does normally find it). The header files are also found when building 2geom. Just the linking seems to fail.
Although not really understanding why, but sometimes, when compiling inkscape I had to remove the old inkscape package first as 2geom did not get built properly (it was omitted/skipped).
Does it help to remove the old 2geom package first, before compiling the new one?
(hmmm; at my end on current the error does not show up, and compiling works when 2geom is present; so dunno whether this would work)
When compiling Inkscape 1.3.2 with a modified SlackBuild from SBo, it didn't build successfully until I enabled -DWITH_INTERNAL_2GEOM=ON in the cmake options. I forgot what was causing the original to not build though.
