SCIP-7.0.3 breaks with zimpl-3.3.6: hidden symbol `xlp_conname_exists' in CMakeFiles/scip.dir/scip/reader_zpl.c.o is referenced by DSO

[yurivict]

/usr/local/bin/ld: ../bin/scip: hidden symbol `xlp_conname_exists' in CMakeFiles/scip.dir/scip/reader_zpl.c.o is referenced by DSO
/usr/local/bin/ld: final link failed: bad value
c++: error: linker command failed with exit code 1 (use -v to see invocation)
*** [bin/scip] Error code 1

It appears that the cause is that xlp_conname_exists is defined in both SCIP and ZIMPL projects.

OS: FreeBSD 13
clang-11

Hey @yurivict can you please add what your compile commands are? Are you using make or cmake? What is the linker call that fails (maybe you need to add VERBOSE=true to the call?)

[leoneifler]

It is intended that this method is defined in the reader_zpl.c. It is declared in xlpglue.h in ZIMPL and the definition inside ZIMPL is only when you build the ZIMPL binary, not when you build the library.
As @fschloesser pointed out, it would be helpful if you could share your build setup (I see that you are using cmake but more information is needed to pinpoint the issue.

@yurivict did you resolve you issue or have some more information here?

This doesn't seem to be an issue now since both FreeBSD ports are at these versions.

Thank you.
