Progress update (from the Fpc make thread): ------------------------------------------- I proceeded to create a script that rebuilds fpc using the info obtained here. I applied it on the rpi4-dev machine where fpc was installed as ARMv7. Took 10 minutes to complete the three steps. > make clean > make all > make install Then I built the test application and copied it over to the PiZero where it did work just fine! No more exceptions! So I can confirm that this rebuild method works. -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
