Hi all,

I have just compiled the new fpc3.1.1 from svn for mips-linux
platform, when I compile a simple test program I get the following
error.
Here is the test program and the output.

program test;
begin
  writeln('DATE ',{$i %DATE%});
  writeln('FPCTARGET ',{$i %FPCTARGET%});
  writeln('FPCTARGETCPU ',{$i %FPCTARGETCPU%});
  writeln('FPCTARGETOS ',{$i %FPCTARGETOS%});
  writeln('FPCVERSION ',{$i %FPCVERSION%});
end.

fpc -Tlinux -Pmips test.pas
Free Pascal Compiler version 3.1.1 [2016/06/11] for mips

Assembling test
test.pas(7,42) Error: Assembler mips-linux-as not found, switching to

test.pas(7,42) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted
Error: /usr/lib/fpc/3.1.1/ppcrossmips returned an error exitcode

My crosscompiled binutils directory is /usr/mips-linux/bin
and I changed the fpc.cfg just like that.

#IFDEF CPUMIPS
-XP/usr/mips-linux/bin/
-Xr/usr/lib/fpc/3.1.1/units/mips-linux/rtl/
-dmips
-Tlinux
#ENDIF

Could someone point me out the right direction? What could be wrong?
Thanks.

-dmips
-Tlinux
#ENDIF
from fpc -h:
Quote-XP<x>     Prepend the binutils names with the prefix <x>
That means the assembler and linker will be searched as /usr/mips-
linux/bin/as and /usr/mips-linux/bin/ld, respectively, which is wrong.
What you need is:
Quote-e<x>  Set path to executable
-FD<x>     Set the directory where to search for compiler utilities
From the official docs:
Quote-exxx
    Specify xxx as the directory containing the executables for the
programs as (the assembler) and ld (the linker).
-FD
    Same as -e.
while maintaining -XP$FPCTARGET- so that assembler and linker will be
searched as mips-linux-as and mips-linux-ld, respectively, which is
right.

thanks leledumbo , it works perfectly, by the way test example works
in onion-omega device.
