Build cross compile tool chain for PPC

Build cross compile tool chain for PPC

[刘林]

Hi, All,

I am a newby for ppc embedded linux. When trying to build the cross compiling tool
chain, I got some error message in making glibc (binutils and gcc are successfully
built).

Error message is:

{quote}
assert.c: In function ¡®__assert_fail¡¯:
assert.c:54: error: ¡®__libc_pthread_functions_init¡¯ undeclared (first use in
this function)
assert.c:54: error: (Each undeclared identifier is reported only once
assert.c:54: error: for each function it appears in.)
assert.c:54: warning: implicit declaration of function ¡®PTHFCT_CALL¡¯
assert.c:54: error: ¡®ptr_pthread_setcancelstate¡¯ undeclared (first use in this
function)
assert.c:54: warning: left-hand operand of comma expression has no effect

make[1]: *** [assert/subdir_lib] Error 2
make[1]: Leaving directory
`/root/embedded_linux/ppc/build-tools/build-glibc/glibc-2.7'
make: *** [all] Error 2

{quote}

My environments are:

kernel: 2.26.     25
gcc & powerpc-linux-gcc: 4.3.2
binutils:2.18
glibc:2.7, configured with  linuxthreads enabled and nptl disabled.

My question is which packages should be used to build the toolchain for kernel
2.26.25
? Am I choosing the right version of these packages? Where can I find such
information?

Thank you very much in advance for any hints or suggestions.

Best Regards.

Lin

glibc 2.7 does not support linuxthreads.  It is nptl only.  And you
should really be using nptl anyway.

Building cross toolchains is a complicated thing; you may want to have a
look at the existing community build tools, like for example
OSELAS.Toolchain:

http://www.pengutronix.de/oselas/toolchain/index_en.html

The latest beta for 2.0 is here:
http://www.pengutronix.de/oselas/toolchain/download/OSELAS.Toolchain-1.99.0.tar.bz2
(gcc-4.3.2, glibc-2.8, binutils-2.18, kernel-headers-2.6.26)

The more stable 1.x series is here:
http://www.pengutronix.de/oselas/toolchain/download/OSELAS.Toolchain-1.1.1.tar.bz2
(gcc-4.1.2, glibc-2.6, binutils-2.16, kernel-headers-2.6.18)
