I think there could be something wrong with the HPIPM & BLASFEO targets.
Can you try the following, namely recompiling with GENERIC and running a C example:
cd <acados_dir>
rm build/* -rf
cd build
cmake .. -DACADOS_WITH_QPOASES=ON -DACADOS_EXAMPLES=ON -DHPIPM_TARGET=GENERIC -DBLASFEO_TARGET=GENERIC
make -j4
make install -j4
# run a C example, e.g.:
./examples/c/sim_wt_model_nx6
If that works, also try the Python example.
This is outdated. I will update the instructions soon.
Cheers,
Jonathan
