final gcc compiler can't find pthread.h even though it *is* in the include dir

[Vandra Akos <axos88 at yahoo dot com dot au>]

Hello everyone,

I am trying to build a toolchain for arm-linux cross-development from a standard x86 PC. I've successfully build the gcc bootstrap compiler, and built the uClibc libraries with it. However, when I try to build the final gcc compiler, it fails.

It seems it can't find pthread.h even though it *IS* in the include path.

I've checked the makefile, and it reads



prefix = /home/akos/ARM/tools

(...)

includedir=${prefix}/include


akos@akosv:~/ARM/build-tools/build/gcc-final$ ls -l /home/akos/ARM/tools/include/ | grep pthread.h

-rw-r--r-- 1 akos akos  24823 2006-12-08 05:19 pthread.h



So the file exists. Why can't the gcc bootstrap find it?



I configured the final gcc compiler with

export TARGET=arm-linux
export PREFIX=/home/akos/ARM/tools


akos@akosv:~/ARM/build-tools/build/gcc-final$ ../../gcc-4.0.2/configure
--target=${TARGET} --prefix=${PREFIX} --program-prefix=${TARGET}-
--disable-threads --enable-languages=c --disable-libmudflap
--disable-shared



But when I issue make, it gives this error:

                 from ../../../gcc-4.0.2/gcc/gthr.h:114,

Can you help me fiugre out what is wrong?
