Trying to crosscompile to win32 from Linux64
lazarus / 1-Linux

Hello,

I am trying to set up my lazarus to both create linux64 and 
crosscompile to win32 executables.

I have managed to follow the instructions here:

http://wiki.lazarus.freepascal.org/Cross_compiling_for_Win32_under_Lin
ux

and here:

http://wiki.lazarus.freepascal.org/Cross_compiling

albeit with some horrible pitfalls which I will later detail so that
others don't fall into them. However now I am stuck with building the
lazarus win32 components and library when I try to in
/usr/lib/lazarus:

sudo make clean all OS_TARGET=win32 CPU_TARGET=i386

I get the following error:

Error: ppc386 can't be executed, error message: Failed to execute
"ppc386", error code: 127

I have ppc386.exe in my /home/x/cross_fpc directory which was created
when compiling fpc for win32 and I tried copying it to /usr/bin where
fpc is (which really doesn't make sense since I think ppc386 is a
windows executable).

What I am missing?

QuoteWhat I am missing?You should have ppcross386 (linux ELF
executable) instead of ppc386.exe (Win32 PE executable). I wonder how
you get that ppc386.exe, if you invoke make clean all OS_TARGET=win32
CPU_TARGET=i386 in FPC source dir while you're on Linux64, you should
get ppcross386 above.

Thanks Leledumbo.

I found ppcross386 in my fpc sources folder and copied it to my
/usr/bin folder

Lazarus now makes and installs fine to the target OS and CPU. I was
able to crosscompile my first application without any problems and it
runs fine in my target computer. What a joy!

Still mistified as to why it would try to use ppc386.exe when
ppcross386 is not present. I guess its a bug?

QuoteI found ppcross386 in my fpc sources folder and copied it to my
/usr/bin folderYou better put in under /usr/lib/fpc/<version>, as that
is where other ppXXX should reside. In /usr/bin, create only its
symlink.

about this, it should actually fail to find it. e.g. emitting message
like:
QuoteError: ppcross386 can't be executed, error message: Failed to
execute ""ppcross386"  dummy.pas ", error code: 2
