Linux SUMO build problem

[MoMingQimio]

When I build SUMO in ubuntu20.04, I run into an error:

/usr/bin/ld: /lib/x86_64-linux-gnu/libp11-kit.so.0: undefined reference to ffi_type_uint8@LIBFFI_BASE_7.0' /usr/bin/ld: /lib/x86_64-linux-gnu/libp11-kit.so.0: undefined reference to ffi_prep_closure_loc@LIBFFI_CLOSURE_7.0'

the command I used is as below:
cmake --build build -j$(nproc)

how do i do to fix this problem??

[MoMingQimio]

it fixed it using the method below:
@SarveshThakur I was able to solve this problem on Ubuntu 20.04 with rm ${CONDA_PREFIX}/lib/libffi.7.so ${CONDA_PREFIX}/lib/libffi.so.7 The problem is that those are dynamically linked to libffi8, which is incorrect. –

[AhmetNeoSari]

This error is caused by incompatibility of different versions of the libffi library. The error is caused by a version mismatch of the libffi library. In particular, the symbolic linking of libffi.so.7 to libffi.so.8.1.0 causes this error. This is my solution on ubuntu 20.04 and ros2 foxy

Navigate to the lib directory of your Conda virtual environment:

cd ~/anaconda3/envs/<xxx>/lib

Back up the existing libffi.so.7 connection:

mv libffi.so.7 libffi.so.7.bak

Create the new symbolic link:

ln -s /lib/x86_64-linux-gnu/libffi.so.7.1.0 libffi.so.7

Update the connection cache:

sudo ldconfig
