Hi,

enjoy your holidays, I have no time pressure switching to the new toolchain!

After learning about logfiles and ptxdist :D, the command-wrapper produces reasonable output on console in the libpng folder. There is no output when I prefix ccache, but calling the compiler directly the output is like this:

<snip>
/opt/OSELAS.Toolchain-2012.12.0/i686-atom-linux-gnu/gcc-4.7.2-glibc-2.16.0-binutils-2.22-kernel-3.6-sanitized/bin/i686-atom-linux-gnu-cpp  -frecord-gcc-switches -isystem /home/gschenk/projects/prodos3_experimental/ptxdist/platform-BB11QA6/sysroot-target/include -isystem /home/gschenk/projects/prodos3_experimental/ptxdist/platform-BB11QA6/sysroot-target/usr/include -DPNG_CONFIGURE_LIBPNG -DPNG_BUILDSYMS ./png.h

# 1 "./png.h"

typedef unsigned char Byte;

typedef unsigned int uInt;
typedef unsigned long uLong;

...

extern PNG_FUNCTION_EXPORT png_save_uint_16 END
   (png_bytep buf, unsigned int i);

</snip>

Attached you find two logfiles, one with ccache enabled, one without. I tried to figure out what is going on, but I need a Guru ... THATS YOU :D. I hope to become more familiar with ptxdist in future.

Maybe it is the order, or parallelization of build process? I have a Multi-CPU system with 8 cores.

Even when I disable ccache the buildprocess does not finish. Next I am bailing out at building gdbserver.
make[1]: Entering directory `/var/projects/prodos3_experimental/ptxdist/platform-BB11QA6/build-target/gdbserver-7.2-build
...
/var/projects/prodos3_experimental/ptxdist/platform-BB11QA6/build-target/gdbserver-7.2/gdb/gdbserver/linux-low.c:4691:40: error: invalid application of 'sizeof' to incomplete type 'struct siginfo'
...

Thanks for your help,
Gavin
