I didn't debug the build system too much, a build with ld --as-needed fails
with:
c++ -Xlinker --no-undefined -lm -pthread -lhdf5 -llapack -lcblas -lglpk -lm
-llzo2 -lz -llzma -L../libshogun -lshogun -shared -L /usr/lib/octave-3.2.4
-loctinterp -loctave -lcruft -o Classifier.oct Classifier_wrap.cxx.o
sg_print_functions.cpp.o -L../libshogun -lshogun
Classifier_wrap.cxx.o: In function `SWIG_check_num_args':
/build/buildd/shogun-0.9.3/src/octave_modular/Classifier_wrap.cxx:785: undefined
reference to `error(char const*, ...)'
/build/buildd/shogun-0.9.3/src/octave_modular/Classifier_wrap.cxx:783: undefined
reference to `error(char const*, ...)'
Classifier_wrap.cxx.o: In function `octave_swig_ref::operator new(unsigned
int)':
/build/buildd/shogun-0.9.3/src/octave_modular/Classifier_wrap.cxx:1727:
undefined reference to `octave_allocator::alloc(unsigned int)'
Classifier_wrap.cxx.o: In function
`octave_value_typeinfo::lookup_binary_op(octave_value::binary_op, int, int)':
/usr/include/octave-3.2.4/octave/ov-typeinfo.h:138: undefined reference to
`octave_value_typeinfo::instance'
[further undefined reference messages omitted]
the reason is that objects and local libraries have to appear on the command
line first, like:
c++ -Xlinker --no-undefined -shared \
-o Classifier.oct \
Classifier_wrap.cxx.o \
-L../libshogun -lshogun \
-lm -pthread -lhdf5 -llapack -lcblas -lglpk -lm -llzo2 -lz -llzma \
-L /usr/lib/octave-3.2.4 -loctinterp -loctave -lcruft
any hint where to fix this properly?
