Until recently we have added libmudflap support via gcc-runtime_4.8.bbappend.
Libmudflap is no longer supported in gcc 4.9 and Libsanitizer is the
recommended replacement. I have changed the recipe to produce libsanitizer
instead of libmudflap but I am getting a QA error involving libtool relink with
–L/usr/lib.
I am unable to establish the cause of the problem. Could someone with libtool
expertise please help me
$ cat gcc-runtime_4.9.bbappend
# Addition of Asan address sanitizer (previously Mudflap)
PRINC := "${@int(PRINC) + 1}"
# enable-libmudflap and disable-libmudflap options no longer supported
EXTRA_OECONF_BASE := "${@oe_filter_out('--disable-libmudflap',
'${EXTRA_OECONF_BASE}', d)}"
RUNTIMETARGET += "libsanitizer"
PACKAGES += "libasan libasan-dev libasan-staticdev libasan-preinit libubsan
libubsan-dev libubsan-staticdev"
FILES_libasan = "${libdir}/libasan*.so.*"
