Hi toolchain folk,
I've recently tried using the base system clang as an external
toolchain i.e.
make CROSS_COMPILER_PREFIX=/usr/bin/ buildworld
.. and found that this no longer works after r273755 which split
XFLAGS into XC/XCXXFLAGS. This appears to be because the XFLAGS
definitions that define --sysroot and -B options aren't being passed
through to clang, resulting in using header files from the host system.
My quick hack was
--- Makefile.inc1 (revision 278542)
+++ Makefile.inc1 (working copy)
@@ -374,6 +374,8 @@
TARGET_ABI?= unknown
TARGET_TRIPLE?= ${TARGET_ARCH:C/amd64/x86_64/}-${TARGET_ABI}-freebsd11.0
XCFLAGS+= -target ${TARGET_TRIPLE}
+XCFLAGS+= ${XFLAGS}
+XCXXFLAGS+= ${XFLAGS}
.endif
.endif
However, this doesn't look to be the right way to fix this.
Any opinions on a proper fix ?
later,
Peter.
