[Xenomai-help] Compiler Errors with User Space Tools for 2.4.6.1

Hello,

I am working on getting Xenomai 2.4.6.1 working on a custom board with
an Atmel AT91SAM9260 processor. The IPIPE patch I used was
adeos-ipipe-2.6.25-arm-1.9-02.patch. My kernel patches, compiles, and
runs on the board.

However, when compiling the user space tools, make fails when it gets
the pSOS+ skin with an error of PTHREAD_STACK_MIN being undeclared.
PTHREAD_STACK_MIN is not defined as the include/posix/pthread.h does not
appear correctly included in the path for the src/ programs.

This are the configure and make commands I used:

configure CC="arm-linux-gnueabi-gcc -v" CXX=arm-linux-gnueabi-gcc
AR=arm-linux-gnueabi-ar LD=arm-linux-gnueabi-ld \
        --build=i686-pc-linux-gnu \
        --host=arm-linux \
        --enable-arm-mach=at91sam926x \
        --enable-arm-eabi \
        --enable-arm-tsc
make DESTDIR=/projects/som9260/xenomai/_install install

These options worked correctly with Xenomai 2.4.3 and I did not see any
changes from the current configure help or from README.INSTALL. If
someone could point out what I am doing wrong here, I would appreciate
the assistance.

I already had this bug, and it turned out to be a toolchain bug.
PTHREAD_STACK_MIN was defined in /usr/local/arm-linux/include/limits.h,
whereas the toolchain found the limits.h from its system includes before
this header. The cure was to add a -I/usr/local/arm-linux/include to the
CPPFLAGS.

Note that if you pass --host=arm-linux-gnueabi to configure, configure
guesses the correct values for CC, CXX, AR and LD.
