Note: like the /usr/local/lib/*.so* files, the wget and git were built previously to the existence of the ASAN&UBSAN world. chrooted into the world I built with ASAN and UBSAN: # ldd `which wget` /usr/local/bin/wget: libintl.so.8 =3D> /usr/local/lib/libintl.so.8 (0x800edc000) libunistring.so.2 =3D> /usr/local/lib/libunistring.so.2 = (0x80182b000) libidn2.so.0 =3D> /usr/local/lib/libidn2.so.0 (0x801b76000) libssl.so.111 =3D> /usr/lib/libssl.so.111 (0x80229d000) libcrypto.so.111 =3D> /lib/libcrypto.so.111 (0x803a00000) libdl.so.1 =3D> /usr/lib/libdl.so.1 (0x8034ed000) libz.so.6 =3D> /lib/libz.so.6 (0x80585d000) libc.so.7 =3D> /lib/libc.so.7 (0x806e00000) libthr.so.3 =3D> /lib/libthr.so.3 (0x8063fc000) # ldd `which git` /usr/local/bin/git: libpcre2-8.so.0 =3D> not found (0) libz.so.6 =3D> /lib/libz.so.6 (0x801bc5000) libintl.so.8 =3D> not found (0) libthr.so.3 =3D> /lib/libthr.so.3 (0x8009ab000) libc.so.7 =3D> /lib/libc.so.7 (0x804000000) Note the differing results for finding libintl.so.8 . The ldd and which runs get no ASAN reports and no UBSAN reports. SIDE NOTE I will note that attempting to use the wget results in: # wget ld-elf.so.1: /usr/lib/libssl.so.111: Undefined symbol = "__asan_option_detect_stack_use_after_return" END SIDE NOTE Instead chrooted into my normal world built for chrooting into main (no ASAN/UBSAN involvement): % ldd `which wget` /usr/local/bin/wget: libintl.so.8 =3D> /usr/local/lib/libintl.so.8 (0x8022a3000) libunistring.so.2 =3D> /usr/local/lib/libunistring.so.2 = (0x801c69000) libidn2.so.0 =3D> /usr/local/lib/libidn2.so.0 (0x803227000) libssl.so.111 =3D> /usr/lib/libssl.so.111 (0x80372d000) libcrypto.so.111 =3D> /lib/libcrypto.so.111 (0x803a37000) libdl.so.1 =3D> /usr/lib/libdl.so.1 (0x805668000) libz.so.6 =3D> /lib/libz.so.6 (0x804618000) libc.so.7 =3D> /lib/libc.so.7 (0x806aca000) libthr.so.3 =3D> /lib/libthr.so.3 (0x80468a000) % ldd `which git` /usr/local/bin/git: libpcre2-8.so.0 =3D> /usr/local/lib/libpcre2-8.so.0 = (0x801b2d000) libz.so.6 =3D> /lib/libz.so.6 (0x801324000) libintl.so.8 =3D> /usr/local/lib/libintl.so.8 (0x801fe8000) libthr.so.3 =3D> /lib/libthr.so.3 (0x802ed9000) libc.so.7 =3D> /lib/libc.so.7 (0x803d98000) Note that both libintl.so.8 and libintl.so.8 were found, as expected. (wget and git both run just fine as well.) It is the same /usr/local/ file system, used from the two contexts (mounted into the chroot trees). It appears that lots of ports from that /usr/local/ tree get "Shared object not found" messages for one or more /usr/local/lib/*.so* files (matching up with ldd reports of not found). =3D=3D=3D Mark Millard marklmi at yahoo.com
