I am unable to reproduce your issue. That said, I am using standard
Makefiles, that is:
XENO_CONFIG = DESTDIR="$(staging)" $(staging)/bin/xeno-config
XENO_NATIVE_CPPFLAGS = $(shell $(XENO_CONFIG) --skin=native --cflags)
XENO_NATIVE_LIBS = $(shell $(XENO_CONFIG) --skin=native --ldflags)
Where staging would be "/" in your case.
If I want static libraries, I prepend -static to XENO_NATIVE_LIBS, I do
not try to link both with static and dynamic libraries. I suspect this
is the cause of your problem, either that or the fact that you have some
ulimit.
Note that my toolchain does not even allow mixing static and dynamic
libraries. I get this warning when linking:
/usr/local/arm-2010q1/bin/../lib/gcc/arm-none-linux-gnueabi/4.4.1/../../../../arm-none-linux-gnueabi/bin/ld:
/usr/local/arm-2010q1/bin/../arm-none-linux-gnueabi/libc/armv4t/usr/lib/libc.a(dl-tsd.o)(.text+0x18):
R_ARM_TLS_LE32 relocation not permitted in shared object
And a segmentation fault when running (though I do not even access the
mmapped area).
