I built ubuntu package on sid, and this package ubuntu-sourced but debian-built works ok on impish, so ... What is the difference between the two compilations mode? or, does it link something different?
Doing a ldd -v on libpostfix-tls.so* from @paelzer in comment [#22]( https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1885403/comments/22), we see that in debian-built version appears libpthread.so and it doesn't appear in ubuntu-built version: ---- Debian Version information: ./libpostfix-tls.so.debugdebian: libpthread.so.0 (GLIBC_2.2.5) => /lib/x86_64-linux-gnu/libpthread.so.0 libc.so.6 (GLIBC_2.14) => /lib/x86_64-linux-gnu/libc.so.6 libc.so.6 (GLIBC_2.4) => /lib/x86_64-linux-gnu/libc.so.6 libc.so.6 (GLIBC_2.3) => /lib/x86_64-linux-gnu/libc.so.6 libc.so.6 (GLIBC_2.2.5) => /lib/x86_64-linux-gnu/libc.so.6 libcrypto.so.1.1 (OPENSSL_1_1_0) => /lib/x86_64-linux-gnu/libcrypto.so.1.1 libssl.so.1.1 (OPENSSL_1_1_1) => /lib/x86_64-linux-gnu/libssl.so.1.1 libssl.so.1.1 (OPENSSL_1_1_0) => /lib/x86_64-linux-gnu/libssl.so.1.1 ---- Ubuntu Version information: ./libpostfix-tls.so.debugubuntu: libc.so.6 (GLIBC_2.14) => /lib/x86_64-linux-gnu/libc.so.6 libc.so.6 (GLIBC_2.4) => /lib/x86_64-linux-gnu/libc.so.6 libc.so.6 (GLIBC_2.3) => /lib/x86_64-linux-gnu/libc.so.6 libc.so.6 (GLIBC_2.2.5) => /lib/x86_64-linux-gnu/libc.so.6 libcrypto.so.1.1 (OPENSSL_1_1_0) => /lib/x86_64-linux-gnu/libcrypto.so.1.1 libssl.so.1.1 (OPENSSL_1_1_1) => /lib/x86_64-linux-gnu/libssl.so.1.1 libssl.so.1.1 (OPENSSL_1_1_0) => /lib/x86_64-linux-gnu/libssl.so.1.1 Also, doing a readelf -a , we see libpthread.so also as NEEDED for debian, but not for ubuntu: ---- Debian Dynamic section at offset 0x27120 contains 34 entries: Tag Type Name/Value 0x0000000000000001 (NEEDED) Shared library: [libssl.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libcrypto.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libpthread.so.0] 0x0000000000000001 (NEEDED) Shared library: [libpostfix-dns.so] 0x0000000000000001 (NEEDED) Shared library: [libpostfix-global.so] 0x0000000000000001 (NEEDED) Shared library: [libpostfix-util.so] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] 0x000000000000000e (SONAME) Library soname: [libpostfix-tls.so] 0x000000000000001d (RUNPATH) Library runpath: [/usr/lib/postfix] Version needs section '.gnu.version_r' contains 4 entries: Addr: 0x00000000000053e0 Offset: 0x0053e0 Link: 4 (.dynstr) 000000: Version: 1 File: libpthread.so.0 Cnt: 1 0x0010: Name: GLIBC_2.2.5 Flags: none Version: 6 0x0020: Version: 1 File: libc.so.6 Cnt: 4 ---- Ubuntu Dynamic section at offset 0x28340 contains 33 entries: Tag Type Name/Value 0x0000000000000001 (NEEDED) Shared library: [libssl.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libcrypto.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libpostfix-dns.so] 0x0000000000000001 (NEEDED) Shared library: [libpostfix-global.so] 0x0000000000000001 (NEEDED) Shared library: [libpostfix-util.so] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] 0x000000000000000e (SONAME) Library soname: [libpostfix-tls.so] Version needs section '.gnu.version_r' contains 3 entries: Addr: 0x0000000000005460 Offset: 0x005460 Link: 5 (.dynstr) 000000: Version: 1 File: libc.so.6 Cnt: 4 Apart from the number of entries varies on most of the sections and this section not present on debian (.note.gnu.property is not present in the segment section): Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000010 NT_GNU_PROPERTY_TYPE_0 Properties: x86 feature: IBT, SHSTK Why this libpthread difference?
