The error is: gcc -c -O2 -pipe -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -DHAVE_CONFIG_H -I. -I. -I/var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc -I/var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/. -I/var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/config -I/var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/../include /var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/cppspec.c -o cppspec.o In file included from /var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/gcc.c:87: /var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/pie-ssp-chain.h:74:2: warning: suggest hiding #error from traditional C with an indented # /var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/gcc/pie-ssp-chain.h:74:2: #error we need ld w/ -pie support So, it looks like a problem with the binutils package (since ld is part of binutils). I haven't tried cross-compiling with gentoo, so I don't know how to fix this unfortunately...but at least now you know what to google for! -Richard -- gentoo-user@gentoo.org mailing list
