There are informations on how to build a bpy python module from blender source but, it does not work (for me) using Ubuntu x64 16.04LTS.

We need a working guidance !?

Building it up with: https://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Linux/Ubuntu/CMake

but use

sudo ./blender/build_files/build_environment/install_deps.sh

...and at the end:

cd ~/blender-git/blender
make bpy

or: different cmake config: https://wiki.blender.org/index.php/User:Ideasman42/BlenderAsPyModule


  • building blender bin is fine out of the box.
  • but make configs and also "make bpy" throws errors:

    requires dynamic R_X86_64_32 reloc which may overflow at runtime; recompile with -fPIC

some solution for this is to:


build up python on your own with "enable-shared" and copy over libpython3.6m.a

sudo apt install build-essential checkinstall
sudo apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.xz
tar xvf Python-3.6.0.tar.xz
cd Python-3.6.0/
./configure --enable-shared
sudo make altinstall

and copy over libpython3.6m.a from /usr/local/lib/python3.6/config-3.6m-x86_64-linux-gnu/libpython3.6m.a to /opt/lib/python-3.6/lib

BUT the main problem is

sudo ./blender/build_files/build_environment/install_deps.sh

which should behave the way to build python with fPIC right away !


Answered from blendercoders chat: There is a pending fix for it: https://developer.blender.org/D3078 But not in master today.


Question: Is it the purpose not to include folder "2.79" on "make bpy" so there are files missing -- compared to the ^^Ideasman42 config, is there a pending fix or is that "working as designed" - could it be made better!?

  • $\begingroup$ Where did you get the sources? How did you try to build Blender? $\endgroup$ – dr. Sybren Mar 12 '18 at 10:07
  • $\begingroup$ I followed the discription on: wiki.blender.org/index.php/Dev:Doc/Building_Blender/Linux/… ..... ./blender/build_files/build_environment/install_deps.sh $\endgroup$ – sonicdee Mar 12 '18 at 10:42
  • $\begingroup$ That page doesn't describe where to get the sources from. Did you use Git? Which revision/branch did you check out? Add this to your question, so that it's clear in one read for others, without having to require them to read through all the comments. $\endgroup$ – dr. Sybren Mar 12 '18 at 10:45
  • $\begingroup$ as first point says, I used: git clone git.blender.org/blender.git ..and.. git submodule update --init --recursive ..and.. git submodule foreach git checkout master ..and.. git submodule foreach git pull --rebase origin master $\endgroup$ – sonicdee Mar 12 '18 at 10:51
  • $\begingroup$ ..on the error on top - I tried the way to set up pyenv as alexlee posted gist.github.com/alexlee-gk/… but It does not work better I get the "relocation R_386_GOTOFF" errors, still I'ts not out of the box or should it do build up with "make bpy" ? - as I'm not familar on the dependencies and building stuff, It may be worse now ... trying fresh $\endgroup$ – sonicdee Mar 12 '18 at 11:20

This issue should be fixed by commit 0a02c288aa258e18d19eff0be984f214d556b159


"install_deps: Enable PIC in Python static library."

I was discussed here: https://developer.blender.org/D7177
