I've now spent quite some time investigating this and finally found the problem: libopenjp2-7-dev (>= 2.1.1) has changed it's /usr/include/openjpeg-2.1/openjpeg.h to include the following lines: #if defined(OPJ_STATIC) || !defined(_WIN32) /* http://gcc.gnu.org/wiki/Visibility */ # if __GNUC__ >= 4 # if defined(OPJ_STATIC) /* static library uses "hidden" */ # define OPJ_API __attribute__ ((visibility ("hidden"))) # else # define OPJ_API __attribute__ ((visibility ("default"))) # endif This makes all API symbols hidden if '-DOPJ_STATIC' is passed to GCC; as it happens to be passed in base/lib.mak : $(GLOBJ)sjpx_openjpeg.$(OBJ) : $(GLSRC)sjpx_openjpeg.c $(AK) \ $(memory__h) $(gserror_h) $(gserrors_h) \ $(gdebug_h) $(strimpl_h) $(sjpx_openjpeg_h) $(LIB_MAK) $(MAKEDIRS) $(GLJPXOPJCC) $(GLO_)sjpx_openjpeg.$(OBJ) \ $(C_) -DOPJ_STATIC $(GLSRC)sjpx_openjpeg.c Patching this -DOPJ_STATIC out fixes the FTBFS; patch attached.

Descrtiption: Don't pass -DOPJ_STATIC when compiling the OpenJPEG code, as it makes the symbols hidden when including /usr/include/openjpeg-2.1/openjpeg.h .
