Segmentation Fault when trying to build on Mac

[JamesTimothyMeech]

Followed the instructions to install project trellis then
cmake . -DARCH=ecp5 -DTRELLIS_INSTALL_PREFIX=/usr/local
make -j$(nproc)
sudo make install
but failed on "make -j$(nproc)" with this error:

I expect this is a duplicate of: YosysHQ/prjtrellis#185

You can try to apply the workaround and see if that fixes it.

Thanks for the tip. Removing libpython3.11.dylib from prjtrellis/libtrellis/CMakeFiles/pytrellis.dir/link.txt did not help for me

[rowanG077]

The comment did not say but I believe you have remove it prior to rebuilding prjtrellis. Did you do this:

1. Run cmake
2. Delete the libpython3.11.dylib from link.txt
3. Run make and install

And then try to build nextpnr.

[JamesTimothyMeech]

I did as you said and I unfortunately still have the same error.

Seems to be fixed by using the newest nextpnr version
