I am trying to compile boost against my custom build of python and getting "undefined reference" errors. Here go details:
1) I build python with support unicode=ucs4 as required by autodesk maya
./configure --prefix=/v/pkgs/python/dep/2.7.14 --enable-unicode=ucs4
make
make install
2) Build boost with this command
b2 -j 4 --layout=versioned --build-type=complete --debug-configuration stage
and config file ./tools/build/src/user-config.jam to use my build of python.
using python
: 2.7
: /v/pkgs/python/dep/2.7.14
;
This is part of b2 output, to confirm python selection success:
notice: [python-cfg] Configuring python...

3) To verify I try to build following test.cpp
#include <Python.h>
#include <boost/python.hpp>
int main ()
{
Py_Initialize();
boost::python::object obj;
return 0;
}
with this command (new lines for easier reading):
g++ -g -O2
-I/v/pkgs/python/dep/2.7.14/include/python2.7
-I/v/pkgs/boost/dep/1_61_0
-L/v/pkgs/boost/dep/1_61_0/stage/lib
-lboost_python-gcc48-mt-1_61
-L/v/pkgs/python/dep/2.7.14/lib
-lpython2.7
./test.cpp
I am getting following errors:
/v/pkgs/boost/dep/1_61_0/stage/lib/libboost_python-gcc48-mt-1_61.so: undefined reference to `PyUnicodeUCS4_FromEncodedObject'
/v/pkgs/boost/dep/1_61_0/stage/lib/libboost_python-gcc48-mt-1_61.so: undefined reference to `PyUnicodeUCS4_AsWideChar'
Any tips are welcome, thanks !
