Hi,
Im trying to fix cross-compiling for arm architecture using clang. I added
following patch:
===================================================================
--- Makefile.inc1 (revision 223085)
+++ Makefile.inc1 (working copy)
@@ -226,6 +226,11 @@
GROFF_TMAC_PATH=${WORLDTMP}/legacy/usr/share/tmac
.endif
+.if ${TARGET_ARCH} != ${MACHINE_ARCH} && ${CC:T:Mclang} == "clang"
+CROSSENV+= CC="${CC} -ccc-host-triple ${TARGET_ARCH}-elf-freebsd" \
+ CXX="${CXX} -ccc-host-triple ${TARGET_ARCH}-elf-freebsd"
+.endif
+
# bootstrap-tools stage
BMAKEENV= INSTALL="sh ${.CURDIR}/tools/install.sh" \
PATH=${BPATH}:${PATH} \
Now it compiles up to stage 4.2 where it fails (). For some reason
-ccc-host-triple is not passed to compiler, but it is defined in CC.
Is CROSSENV right place to add -ccc-host-triple ?
Any hints?
Thanks,
Damjan
