Bug ID: 69839
Summary: cross-compiling programs w/-fsanitize=address fails:
ld: warning: libstdc++.so.6, needed by libasan.so, not
found (try using -rpath or -rpath-link)
Product: gcc
Version: 4.9.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: joakim.tjernlund at infinera dot com
Target Milestone: ---
Using gcc 4.9.3 I can using the native gcc build ASAN:
# > gcc -fsanitize=address mmap.c
# >
However, using a ppc32 cross gcc build with crossdev I cannot:
# > powerpc-g2.20-linux-gnu-gcc -fsanitize=address mmap.c
/usr/libexec/gcc/powerpc-g2.20-linux-gnu/ld: warning: libstdc++.so.6, needed by
/usr/lib/gcc/powerpc-g2.20-linux-gnu/4.9.3/libasan.so, not found (try using
-rpath or -rpath-link)
# >
Adding -lstdc++ works though:
# > powerpc-g2.20-linux-gnu-gcc -fsanitize=address mmap.c -lstdc++

# > powerpc-softfloat_4.9.3-linux-gnu-gcc -print-search-dirs
