Dear sir: I get a pth-1.4.0 from ftp://ftp.gnu.org/gnu/pth/ . I wanna build it in my redhat 7 for my vr4181-pda(linux-kernel-2.4.0-test7). I use cross-compile tools based glibc-2.0.7 . I configure it with CC=mipsel-linux-gcc ./configure and then make follow messages I got: ./shtool scpp -o pth_p.h -t pth_p.h.in -Dcpp -Cintern -M '==#==' pth_compat.c pth_debug.c pth_syscall.c pth_errno.c pth_ring.c pth_mctx.c pth_clean.c pth_time.c pth_tcb.c pth_util.c pth_pqueue.c pth_event.c pth_sched.c pth_data.c pth_msg.c pth_cancel.c pth_sync.c pth_attr.c pth_lib.c pth_fork.c pth_high.c pth_ext.c pth_string.c ./libtool --mode=compile --quiet mipsel-linux-gcc -c -I. -O2 -pipe pth_debug.c ./libtool --mode=compile --quiet mipsel-linux-gcc -c -I. -O2 -pipe pth_ring.c ./libtool --mode=compile --quiet mipsel-linux-gcc -c -I. -O2 -pipe pth_pqueue.c ./libtool --mode=compile --quiet mipsel-linux-gcc -c -I. -O2 -pipe pth_time.c ./libtool --mode=compile --quiet mipsel-linux-gcc -c -I. -O2 -pipe pth_errno.c ./libtool --mode=compile --quiet mipsel-linux-gcc -c -I. -O2 -pipe pth_mctx.c pth_mctx.c:242: #error "unknown mctx stack setup" pth_mctx.c:289: #error "unknown mctx stack setup" make: *** [pth_mctx.lo] Error 1 some message got from config post: ./config.guess: ./dummy-26802: cannot execute binary file ./config.guess: ./dummy-26802: cannot execute binary file Platform: i686-mitac-linux-gnu2.2glibc Machine Context Implementation: checking for ucontext.h...
