==== Build boost_python ==== | |||
When using the bash prompt from 'octave-cli.exe' we could not use the libboost-python that we used octave Msys environment with help of MSYS2. First thing we had to do to build boost-python from source. The steps I used to build boost are: | |||
# Open octave-cli.exe | # Open octave-cli.exe | ||
# cd e:/boost_1_61_0 | # cd e:/boost_1_61_0 | ||
| Line 125: | Line 127: | ||
# ./b2 install --with-python --prefix=/e/boost_build | # ./b2 install --with-python --prefix=/e/boost_build | ||
(Tasuro's b2 command) | |||
# ./b2 install link=static,shared --with-python cflags='-IC:/Python27_32/include' cxxflags='-IC:/Python27_32/include' linkflags='-LC:/Python27_32/libs' \ | |||
--prefix=/d/usr/Tatsu/program/Pytave/PytaveBuild/boost/mingw32/boost_1_16_inst | tee b2_static_shared.log | |||
(cflags, cxxflags, and linkflags are needed when python27 are not installed not to default directory. (default C:/Python27 ) | |||
At this moment building of boost-python with 64 bit tool chain fails at final link stage. Using 32 bit octave 4.1.0+ for windows build of boost_python was successful. | |||
So far octave-4.1.0+ 32 bit has been used. | |||
==== Build Pytave (Procedure and current state) ==== | |||
# Open octave-cli.exe | |||
# cd (Pytave build directoy) | |||
# system bash | |||
# export PATH=$PATH:/c/msys64/usr/bin | |||
# ./configure (with CPPFLAGS LDFLAGS setting ) | |||
# make | |||
There was an error in configure that PYTHON_EXTRA_LIBS was 'None' on windows and hence the configure failed. As per Mike's suggestion I set it to a valid gcc flag for the time being with ''export $PYTHON_EXTRA_LIBS=-g'' | There was an error in configure that PYTHON_EXTRA_LIBS was 'None' on windows and hence the configure failed.

After this too the build failed with undefined references to few symbols. Tatsuro suggested to build boost with ''link=static,shared''. He had successfully built boost with it but I could not build boost with this option on my PC. | After this too the build failed with undefined references to few symbols.
