To compile fpc 2.7.1 on rpi, I uninstalled the fpc 2.6 that comes with wheezy, and installed a fpc copy from here http://freepascal.thaddy.co.uk/raspberrypi.html > Have you tried/succeeded in building the latest rpi arm version from trunk > eg v2.7.1? Think jonas suggested that it should work (or did he just say > that 2.6.4 doesn't work?) > Using the FPC 2.7.1 from the cited site, I compiled and installed FPC 2.7.1 trunk successful following these steps: http://www.michellcomputing.co.uk/blog/2014/05/freepascal-2-7-1-on-raspberry-pi/ When I used the stock fpc 2.6.4, downloaded from http://sourceforge.net/projects/freepascal/files/Linux/2.6.4/fpc-2.6.4.arm-linux.tar/download It don't works, don't compile my program nor my shared library. I think that the cause of this, is because my distro (wheezy) is ARMHF and fpc stock is ARMEL. Marco warned me about this... > , but don't know if v2.7.1 is used much. Does it work?

It compiles the program and the shared library, like as fpc 2.6.0+armhf patch, but at runtime, my program can't load my shared library. > > TIA john > > > > On 1 July 2014 14:14, Fabio Luis Girardi <fluisgira...@gmail.com> wrote: > >> Hi all!! >> >> First (tests made on ARMHF): I did tests with latest FPC, built from >> trunk.
