Missing libraries for compilation on Ubuntu 14.04 about pbeam HOT 4 CLOSED

Have you tried building via
python setup.py install
or are you just using
make
?
It looks like your link line does not include lapack (which is why you're missing "dgesv_", etc), and like it does have "main", (which it shouldn't for building the .so).

Subject: [pBEAM] Missing libraries for compilation on Ubuntu 14.04 (#1)

Hi,

I am trying to compile the pBEAM on my Ubuntu 14.04 machine using the makefile scripts. The compilation of the src/pBEAM files works fine. However, there are some issues with the makefile for src/pyBEAM. I modified the makefile script as follows. Still I have the attached error from the compiler.

Do you have any idea which libraries are still missing? It seems to be a python related lib.

Regards,
Malo

src/pyBEAM/makefile:

CXX = clang++
CFLAGS = -O2
PY_FRAMEWORK = /usr/include/python2.7 # /usr/lib/python2.7
BOOST_INCL = /usr/include
BOOST_LIB = /usr/lib/x86_64-linux-gnu
INCL = -I$(BOOST_INCL) -I$(PY_FRAMEWORK) -I../pBEAM
LIB = $(BOOST_LIB)/libboost_python.a $(BOOST_LIB)/libboost_system.a $(BOOST_LIB)/libpython2.7.a -lpthread -lz -ldl -lutil #some python lib?
OBJ = ../pBEAM/Poly.o ../pBEAM/myMath.o ../pBEAM/BeamFEA.o ../pBEAM/Beam.o

pybeam: pyBEAM.o
$(CXX) pyBEAM.o $(OBJ) -Xlinker -E $(LIB) -o _pBEAM.so

.cpp.o:
$(CXX) $(INCL) $(CFLAGS) -c $&lt; -o $@

clean:
rm -f *.o _pBEAM.so

compiler output:

Yes, sorry if you were confused by those makefiles. Those are only there for my own use to run some unit tests. The setup.py files are what you should use to build. You will need to install LAPACK and BLAS first.

should this issue be closed? @andrewning or @pgraf? please do if so

I'm closing this issue after our discussion, but if you are still having issues let us know.
