gmic-lib @3.2.3: upgrade fails with link error, when previous version active

[mascguy (Christopher Nielsen)]

Presumably should be a relatively easy fix, by changing the link order:

gmic-lib/work/compwrap/cxx/usr/bin/clang++ -o use_libgmic use_libgmic.cpp -std=c++11 -pedantic -lgmic -L/opt/local/lib -lz -L.
-L/opt/local/lib -Wl,-rpath,. -lpthread -L/opt/local/lib -lfftw3 -lfftw3_threads -L/opt/local/lib -lcurl -L/opt/local/lib -lpng16
-L/opt/local/lib -ljpeg -L/opt/local/lib -ltiff -L/opt/local/lib -lX11 -lpthread -L/opt/local/lib -lIlmImf -lImath -lHalf -lIex
-lIexMath -lIlmThread

Deactivating the current version first works, but not very user-friendly.

Full log attached.

We went through that issue several versions ago. Are you upgrading from the previous version, i.e. 3.2.2 or something older?

Replying to Schamschula:

I'm upgrading from 3.1.6. But ultimately, if the link order is being set correctly, should that matter...?

Let's close for now. If this issue reoccurs, we can reopen.
