Description piotr5 2019-11-19 07:32:02 UTC

checking for gsapi_new_instance in -lgs... no
configure: error: You need libgs in order to compile libspectre

first off, strangely app-text/ghostscript-gpl wasn't updated beforehand, problem with dependency? however, looking at config.log shows the real culprit: configure compiled the test-program without media-libs/jbig2dec which is needed in my app-text/ghostscript-gpl-9.26 libs. i.e.

/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../lib64/libgs.so: undefined reference to `jbig2_ctx_new'

can be fixed by adding -ljbig2dec to the $LIBS variable. alternatively upgrading to app-text/ghostscript-gpl-9.50 helped too. maybe completely remove the older broken version?

The problem you are looking at was already fixed in this commit where the sub-SLOT operator on the media-libs/jbig2dec dependency was added:

It should probably help to get your system fully up to date before you try to install new packages.
