i wrote that manual with many googling and trial.

environment

* Ubuntu 20.04 LTS
* python 3.8.10

1. download and install fbx sdk
   • fbx sdk
     • version
       • 202032
     • tar file download path
       • ./<YOUR_FBXSDK_PATH>/
     • instruction
       • cd <YOUR_FBXSDK_PATH>
       • tar zxvf fbx202032_fbxsdk_linux.tar.gz
       • ./fbx202032_fbxsdk_linux.tar.gz
       • export FBXSDK_ROOT=<YOUR_FBXSDK_PATH>
     • you should check env param
   • fbx python binding
     • version
       • 202032
     • tar file download path
       • ./YOUR_FBX_PYTHON_BINDING_PATH/
     • instruction
       • cd <YOUR_FBX_PYTHON_BINDING_PATH>
       • tar zxvf fbx202032_fbxpythonbindings_linux.tar.gz
       • ./fbx202032_fbxpythonbindings_linux.tar.gz
   • reference
     • [autodesk FBX SDK 202032](https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2020-3.2)
     • no need fbx python sdk
2. sip - build tool
   • version
     • 4.19.3
   • file download path
     • ./<YOUR_SIP_PATH>/
   • install
     • cd <YOUR_SIP_PATH>
     • python configure.py
     • make
     • make install
     • export SIP_ROOT=<YOUR_SIP_PATH>
   • you should check env param
   • reference
     • [sip==4.19.3 archive file download](https://sourceforge.net/projects/pyqt/files/sip/sip-4.19.3/)
     • [how to install sip](https://docs.huihoo.com/pyqt/sip4/installation.html)
3. sdk build
   • cd <YOUR_FBX_PYTHON_BINDING_PATH>
   • python PythonBindings.py Python3_x64 buildsip
   • when get problem with lxml
     • sudo apt insatll libxml2-dev
     • python PythonBindings.py Python3_x64 buildsip
4. modify make file and re-install

   • there is possibility of error when import fbx after first build.

     • fbx undefined symbol: xmlFree
     • that is error about link order related with libxml2.so's
     • you should modify the make file
     • [make file modify](https://forums.autodesk.com/t5/fbx-forum/fbx-python-bindings-fails-on-ubuntu-because-of-undefined-symbol/td-p/9538320)

   • cd <YOUR_FBX_PYTHON_BINDING_PATH>/build/Python38_x64

   • make clean

   • open make file and modify

     from
     
     LIBS = -L/workspace/CALM/fbxsdk/lib/gcc/x64/release -lz -lxml2 /workspace/CALM/fbxsdk/lib/gcc/x64/release/libfbxsdk.a
     
     to
     
     LIBS = -L/workspace/CALM/fbxsdk/lib/gcc/x64/release /workspace/CALM/fbxsdk/lib/gcc/x64/release/libfbxsdk.a -lz -lxml2
     

   • make install

   • files are created in <YOUR_FBX_PYTHON_BINDING_PATH/build/Distrib/site-packages/fbx> after installing

     • fbx.so
     • FbxCommon.py
     • fbxsip.so

   • and file is copied to <YOUR_PIP_PATH>/site-packages

     • fbx.so
5. add sys path to your .py file

   • the package paths are not added to python sys.path, you should add path manually.

   • maybe i should move<YOUR_FBX_PYTHON_BINDING_PATH/build/Distrib/site-packages/fbx> to my python site-package. and maybe don't need this step.

     import sys
     sys.path.append('<YOUR_FBX_PYTHON_BINDING_PATH>/build/Distrib/site-packages/fbx/')
     ...

   • now you can successfully import fbx, FbxCommon packages.

I get /usr/bin/ld: cannot find -lz as well as /usr/bin/ld: cannot find -lxml2 while building pythonbindings. It's caused by the missing of both zlib and libxml2 (not sure if it's common to miss libz). The problem can be solved by sudo apt install zlib1g-dev libxml2-dev.
It took me some time to find out which package -lz stands for, so I comment here for those who may stuck on the same problem as me.

I also encountered the same problem in Ubuntu 22.04. Is there any solution?

after modifying the Makefile, run sudo make before make install
