Operating System Compatibility ============================== Dovecot is commonly used with Linux, Solaris, FreeBSD, OpenBSD, NetBSD and Mac OS X. The following operating systems have also worked at least at some point in Dovecot's existence: * BSD/OS 4.2 * AIX 4.3 * HP-UX 11i (Dovecot v1.1+) * Tru64 ?.? * UnixWare 7.1.4 * IRIX 6.5 compiles, but SCM_RIGHTS seems to be broken. * Cygwin apparently doesn't work nowadays. * MidnightBSD (ports) If there are compiling problems with any OS, please send a bug report that includes the error messages. SCM_RIGHTS ---------- There is one slightly problematic feature that Dovecot requires for implementing privilege separation:*SCM_RIGHTS*. If it doesn't work correctly, you'll get errors on 'fd_send()' or 'fd_read()' such as: ---%<------------------------------------------------------------------------- imap-login: fd_send(X) failed: Bad file number ---%<------------------------------------------------------------------------- If this happens, you can still use inetd and mailfront [http://untroubled.org/mailfront/], which executes Dovecot's post-login IMAP or POP3 binary. You can also try defining 'BUGGY_CMSG_MACROS' in 'src/lib/fdpass.c' to see if it helps. Compilers --------- Dovecot should compile with any ANSI-C99 compiler. Dovecot has been known to compile (at least once in its lifetime) with the following compilers: * GCC * Clang * Intel CC [http://www.intel.com/software/products/compilers/clin/] * Tiny CC [http://www.tinycc.org] * Sun Studio 11 * Sun Studio 12 * AIX xlC * HP-UX cc (This file was created from the wiki on 2017-05-11 04:42)
