linker fails building libcarla.obj in make PythonAPI
what could be the reason?

where to show for those unresolved external symbols???

Platform: Windows 10
VS 2017
python 3.7.9 64bit
carla: 0.9.10.1-122-g064760da

make launch OK!
make PythonAPI ERROR!
unresolved LNK2001

Hi,
Usually when we see this error about unresolved external symbol on boost::python, it is caused by a wrong version of Python or a 32 bits version instead of the 64 bits version of Python required. Can you check that?

Yes,
Python 3.7.9 and 3.7.2 checked and both failed. Is there a lib dll or special file in the python package i can or should look for?

Hi
no 32bit version

I've had the exact same issue. I don't know if it will help in your case, but here's what I did:

  1. Delete Build and PythonAPI/carla/build - Directories
  2. Downgrade Python from 3.7.9 to 3.7.7 (it's easiest to completely uninstall python and install the version you need)
  3. make clean
  4. make rebuild

doesn't change anything.
Same errors.
Does anyone have an idea about these errors?
They probably are just correct and a hint ?
" void __cdecl boost::python::converter::registry::insert(struct _object * ( ..."
Where ist this symbol defined?

Hi,

I have exactly the same issue. did you resolve your problem ?

I'm using
Platform: Windows 10
VS 2017 (I also have VS 2019 for other projects)
python 3.9 64bit (but I also have python 3.7 on my computer)
carla: 0.9.10.1

Hi,

Another cause of that problem is that when you build the first time CARLA, when it setup the boost files it takes a python version installed (if you have several it can take one that you don't want), and then later when compiling the PythonAPI the linker is using another version of Python, so it can not link different versions.

So, be sure that by default the same version of Python is found always, and it is 64 bits.

You can check the python that boost was using looking the files here:
CARLA\Build\boost-1.72.0-install\lib\libboost_python37-vc141-mt-x64-1_72.lib
the ..37.. is the version of Python, in this case 3.7

To rebuild, just remove the CARLA\Build\boost-1.72.0-install folder and try to build PythonAPI again with make PythonAPI.

Hi,
I tried the following steps and it works.

  1. Remove all the other versions of Python. (I uninstall Anaconda and reinstall Python 3.7.9 from Python.org.)
  2. Add Python to path variable.
  3. Delete the folders naming with "-install" in CARLA\Build
    image
  4. make clean
  5. make PythonAPI

I hope it will help!

Can you tell us which files are in your CARLA\Build\boost-1.72.0-install\lib\ folder?
That could give us an idea of what version of python was using boost, and which version of python is trying to link CARLA.
If you have the whole .log of the compilation to check, the better.
Thanks

I could solve the problem.

Firstly I was having b2.exe error during "make PythonAPI" which is mentioned in #4534. I downgraded the python version to 3.8.10 from 3.10.xx. I deleted all Carla and python 3.10.xx files and paths then I started from WIndows Build-Part Two: Build CARLA. That solved the b2.exe problem but it starts giving the error of "failed with exit status 1120". After that, I reinstall Make and Cmake. Also don't forget to install python dependencies (setuptools, wheel) again.

Now I am having an "Out of video memory trying to allocate a rendering resource" error when I launch Carla. My PC has 8GB RAM, i5-4210, and Nvidia Geforce 840M. I guess I need a more powerful PC.
Thanks
