While trying to compile 'firework.pp' under packages/ncurse, for

uclibc support has not been maintained for a long time, so if it works
you're lucky.
Since my target SBC dont have libncursesw.so i did a symlink to
libncurses.so.5.6.
Is its functionality also in that library?
Target file system is uclibc based. ppcrossarm is compiled with
arm-linux-uclibcgnueabi-
I am able to compile on host & execute on target a simple
Helloworld.pas.
Using :-
/software/fpc-uclibc/lib/fpc/2.5.1/ppcrossarm -n -MObjFPC -TLinux
-Parmv5 -gl -Xd -Xs -l -darm -XParm-linux-uclibcgnueabi- -CfSOFT
-CaEABI -darm -gl -O- -CpARMV5 examples/firework.pp -uUSE_LOCALIZE
firework.pp -Fu/software/fpc-uclibc/lib/fpc/2.5.1/units/arm-linux/*
-Fl/usr/br-git-rf/usr/lib -FL/usr/br-git-rf/lib/ld-uClibc.so.0
You should use -XR/usr/br-git-rf (note the uppercase R!) instead of
the -Fl. That will set the "root" directory relative to which all
libraries/object files are searched.
I get the following errors when compiling :-
Free Pascal Compiler version 2.5.1 [2009/10/23] for arm

That may be solved by the -XR

That's because of the previous error.

No idea whether these are part of libc or libgcc. You may also have to
add {$linklib gcc} to your program and -Fl/path/to/libgcc to your
command line.
