FBX-installation

The following content is copied from https://github.com/nv-tlabs/ASE/issues/61, and fixed errors & added comments in the original texts.

1. download and install fbx sdk & fbx python binding

   • 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 (install it)
       • 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 (install it)
   • reference
     • autodesk FBX SDK 202032
     • 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
     • how to install sip

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

   • cd <YOUR_FBX_PYTHON_BINDING_PATH>/build/Python38_x64

   • make clean

   • open make file and modify line 11, “LIBS”, move “-lz, -lxml2” to the back.

     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

   • [NOTE] then, in the <YOUR_FBX_PYTHON_BINDING_PATH>/build/Python38_x64, a new “fbx.so” was generated.

   • copy the file “fbx.so” to <YOUR_FBX_PYTHON_BINDING_PATH/build/Distrib/site-packages/fbx>. After that, you can see these three files in that directory:

     • fbx.so
     • FbxCommon.py
     • fbxsip.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 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, import FbxCommon packages.

6. other reference

   • env param setting
