Re: Cross Compiler Host MinGW Target PowerPC

[Sebastian Ebenbeck <seb at work-gmbh dot de>]

Hello,

I found out something.

The make process try to execute:
/home/seb/build/combined/./gcc/xgcc -B/home/seb/build/combined/./gcc/ 
-nostdinc -B/home/seb/build/combined/powerpc-405-eabi/newlib/ -isystem 
/home/seb/build/combined/powerpc-405-eabi/newlib/targ-include -isystem 
/home/seb/combined/newlib/libc/include 
-B/usr/local/powerpc-405-eabi/bin/ -B/usr/local/powerpc-405-eabi/lib/ 
-isystem /usr/local/powerpc-405-eabi/include -isystem 
/usr/local/powerpc-405-eabi/sys-include -O2 -O2 -g -O2 -DIN_GCC 
-DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes 
-Wmissing-prototypes -Wold-style-definition -isystem ./include 
-specs=ldblspecs -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc 
-I. -I -I../../../combined/gcc -I../../../combined/gcc/ 
-I../../../combined/gcc/../include -I./../intl 
-I../../../combined/gcc/../libcpp/include -mrelocatable-lib -mno-eabi 
-mstrict-align -DL_muldi3 -c ../../../combined/gcc/libgcc2.c -o 
libgcc/./_muldi3.o

This fails because of wrong includes:
-I. -I -I../../../combined/gcc -I../../../combined/gcc/  ...
     ^
There is a "-I" argument without a Path?

If I try to compile it without the -I argument:
/home/seb/build/combined/./gcc/xgcc -B/home/seb/build/combined/./gcc/ 
-nostdinc -B/home/seb/build/combined/powerpc-405-e
abi/newlib/ -isystem

-I../../../combined/gcc/../libcpp/include  -mreloca
table-lib -mno-eabi -mstrict-align -DL_muldi3 -c 
../../../combined/gcc/libgcc2.c -o libgcc/./_muldi3.o

I get the error:
xgcc.exe: _spawnvp: No such file or directory

I have taken a look into the Makefile and it seams that "libgcc2.c" is 
compiled with a wrong set of arguments.

I'm usually writing microcontroller software and I am not very familiar 
with such big makefiles.
Can anybody help me, Please?
