Description Dan Barowy 2022-07-16 15:13:50 UTC 
Attempting to use libtesseract from ports (and packages) yields the following error:

ld-elf.so.1: /usr/local/lib/libtesseract.so.5: Undefined symbol "__kmpc_global_thread_num"

__kmpc_global_thread_num appears to be exported by openmp.

Checking /usr/local/lib/libtesseract.so.5 with ldd revealed that openmp was indeed missing.

It's possible that some CMake magic is supposed to be inserting this flag somewhere, but I was able to solve my problem by adding -lomp to the LDFLAGS variable in the port's Makefile.

Does this apply to port graphics/tesseract?

(In reply to Mark Linimon from comment #1)

Yes, sorry if I was not clear, it applies to graphics/tesseract.
