Errors while making gnatlib

Errors while making gnatlib

[Pee Seeumpornroj]

Dear GCC team,

    I'm trying to build a GNAT cross compiler from host=i686-linux-pc to target=powerpc-elf.  After successfully building binutils, gcc, and newlib, I followed the intruction on GCC website to build gnat tools.  I ran into these errors while doing "make gnatlib":

I have dirent.h in my $prefix/$target/include, but I don't know why gcc cannot find it.  Moreover, in adaint.c and adaint.h, it doesn't recogize a type DIR.  Could you let me know if I'm missing any header file or anything?  Thank you very much for your help.

I'm currently using this configuration:

BINUTILSDISTO=binutils-2.14
GCCDISTO=gcc-3.3.2
LINUXDISTO=linux-2.4.3
NEWLIBDISTO=newlib-1.11.0

Hello,

this is basically what bug 6879
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=6879> is
about.

To work around it, you should be able to modify
/home/pee/XComp_source/CrossGNAT/script/build-ada-tools/gcc/ada/Makefile
changing either ADA_INCLUDES, or INCLUDES to include
the  "-I $prefix/$target/include" (making sure to
substitute appropriately for prefix and target).
Cheers,

Dara
