Hello, LibreSSL up to version 2.5.0 builds under AIX 5.3, 6.1 and 7.1 with the IBM XLC compiler without any patches.
LibreSSL 2.5.1 introduced use of the -export-symbols linker flag and corresponding symbol files: libressl-2.5.1/crypto/crypto.sym libressl-2.5.1/crypto/crypto_portable.sym libressl-2.5.1/ssl/ssl.sym libressl-2.5.1/tls/tls.sym To build under AIX with the IBM XLC compiler, patches are needed for version 2.5.1, 2.5.2 and 2.6.1 libressl-2.5.1-aix-symbols.patch libressl-2.5.2-aix-symbols.patch libressl-2.6.1-aix-symbols.patch I can submit the patches if the project has interest in these platform/compiler combinations.
