sorry if this comes thru twice, I think I used the wrong email address
this might help a little bit...
I am still to complete it, there are some tricks to svn for arm that I
haven't documented yet but it should give you a heads up.
also I noted afterwards you aren't crosscompiling... but its an option
anyways, and lazarus / qt crosscompiles no probs (mostly).
trick from clean svn (from memory) is to run fpcmake -Tall (2.2.0
version only - 2.3.1 doesn't work)) and when compiling fails on ffpkg or
similar when installing to zip change into that folder and do the same.
also although it creates an EABI 4 executable correctly there is a
problem with fpc-svn/compiler/systems/t_linux.pas that sticks the wrong
dynamic linker name in the file. I fixed it with this...
probably wrong but IWFM.
