1 year ago Seems zlib symbols provided by the builded zlib and the one shipped in CPLEX are in conflict...
lib/libz.a(gzread.c.o)
/Applications/CPLEX_Studio128/cplex/lib/x86-64_osx/static_pic/libcplex.a(zlib_gzread.o)Try to add a -DBUILD_ZLIB=OFF to disable the build of zlib (in this case it should try to use a dynamic zlib version found in your system) OR try to bump zlib version :shrug:
