[uClibc]Compiling problem

[Cedric Aubert]

Hi,

I try to compile uclibc with cross environnement for
ppc (mpc860) (gcc
2.95.4) of the ELDK 2.0.2 toolkit fron Denx.

I have succesfully build uClibc 0.9.19 but without the
C99 math lib option and without the POSIX pthread
option.

If I enable POSIX pthread option this error occur :

	make[1]: Entering directory
`/home/installateur/embedded-ppc/src/uClibc-0.9.19/libpthread'
	make -C  linuxthreads
	make[2]: Entering directory

	fi;

and It's right crtbeginS.o isn't exist. But what is it
??

and the second error with the C99 option :

	make[2]: Entering directory
`/home/installateur/embedded-ppc/src/uClibc-0.9.19/libm/powerpc'

and I don't understand why.

Any idea ?

thanks a lot
