I have my project compiler options and "build lazarus" both set to
powerpc, I also have the powerpc cross compiler installed.
Although lazarus uses the powerpc lib dirs, it still uses ppc386 to
compile with!
(I had to build the lazarus powerpc libs with:
su -c "cd /usr/share/lazarus/lcl/ && /usr/bin/make clean all -w
CPU_TARGET=powerpc BINUTILSPREFIX=powerpc-linux-gnu-"
because otherwise "build lazarus" lazarus was trying to write to
/usr/share/lazarus and I don't run lazarus as root. Is there a better
way to manage this?)
When I try and build my project lazarus reports:
/usr/share/lazarus/components/jpeg/lazjpeg.pas(1,1) Fatal: Can't find
unit IntfGraphics used by LazJPEG
Although in fact it CAN find it but it is using the wrong compiler and
so thinks it is compiled for the wrong platform;
stderr/stdout from lazarus says:
...
Target OS: Linux for i386
Compiling jpegforlazarus.pas
Compiling lazjpeg.pas
PPU Loading /usr/share/lazarus/lcl/units/powerpc-linux/intfgraphics.ppu
PPU is compiled for another processor
The full output is below, but why is lazarus calling ppc386 anyway
instead of fpc which might at least call the right ppc. Does this come
down to what my fpc cross packages should have put in /etc/fpc.cfg?

So again, it is now missing the binutils prefix. I really think I'm
missing a spell in my /etc/fpc.cfg which I attach
