Description Ambroz Bizjak 2012-09-21 01:06:28 UTC

libcap/Makefile contains this which builds a build tool:

_makenames: _makenames.c cap_names.list.h
        $(BUILD_CC) $(BUILD_CFLAGS) $< -o $@

This fails when BUILD_CFLAGS is not defined. In that case, something makes BUILD_CFLAGS default to CFLAGS, and the native compiler is called with invalid options.

Reproducible: Always

Comment 2 Ambroz Bizjak 2012-09-21 01:10:48 UTC

Working fix:

 src_configure() {
        tc-export BUILD_CC CC AR RANLIB
+       export BUILD_CFLAGS="${BUILD_CFLAGS}"
 }

Note that just "export BUILD_CFLAGS" does not work.
