[fpc-pascal] is there a ready to use FPC Cross compiler x86-Linux -> MIPS-linux?

[Michael Ring]

The other Michael answering now ;-)

Just for fun I downloaded the deb-file you described below, the deb 
package seems to include the correctly named  binaries at correct places:

x ./usr/bin/
x ./usr/bin/mipsel-linux-gnu-addr2line
x ./usr/bin/mipsel-linux-gnu-c++filt
x ./usr/bin/mipsel-linux-gnu-ld.bfd
x ./usr/bin/mipsel-linux-gnu-gprof
x ./usr/bin/mipsel-linux-gnu-strip
x ./usr/bin/mipsel-linux-gnu-size
x ./usr/bin/mipsel-linux-gnu-ld
x ./usr/bin/mipsel-linux-gnu-nm
x ./usr/bin/mipsel-linux-gnu-elfedit
x ./usr/bin/mipsel-linux-gnu-ar
x ./usr/bin/mipsel-linux-gnu-strings
x ./usr/bin/mipsel-linux-gnu-readelf


So please type:

/usr/bin/mipsel-linux-gnu-as -help

if you see the help text then everything is correctly installed on your 
system.

Now make sure that you have BINUTILSPREFIX=mipsel-linux-gnu-as on your 
commandline whenever you try to compile a binary for mips and you should 
be sure that you are indeed using the right cross-versions of as & friends.

And now I'd start on commandline to see if everything works. Here's an 
example that should also work for you:

STEP1:
<PATHWHEREYOURCROSSCOMPILERIS>/ppcrossmipsel -Tlinux -Pmipsel 
-XPmipsel-linux-gnu- hello.pas

when this works and you get a binary (verify it by doing a: 
mipsel-linux-gnu-objdump -a hello.elf)

then next is:

STEP2:
fpc -Tlinux -Pmipsel -XPmipsel-linux-gnu- hello.pas

this will kick in the magic of fpc that selects the crosscompiler based 
on the fpc config files

If this build fails you will need to find out if fpc looks at the right 
places for your crosscompiler and your tools.

STEP3:

fpc -Tlinux -Pmipsel -XPmipsel-linux-gnu- hello.pas -vt

will help you a lot diagnosing problems with wrong paths.

if this now also works then you should have a look on integrating those 
parameters into lazarus (STEP4), doing it this way instead of starting 
with step four before step one should make your live a lot easier 
because the level of complexity and possible problems rises from step to 
step.
