For some shell scripts, it is preferable to have /usr/xpg4/bin at a prominent
position in $PATH.
With the default compiler define _GNU_SOURCE, the CMSG_* macros are not
available, and therefore ancillary messages cannot be used. To enable these try
the following:
After running ./configure, edit Makefile and replace "-D_GNU_SOURCE" with
"-D_XPG4_2 -D__EXTENSIONS__" and run make
platform specifics - hp-ux
--------------------------
Ancillary messages cannot be compiled in with socat: both struct msghdr and
strutc cmsghdr are required. Compiling with -D_XOPEN_SOURCE_EXTENDED provides
struct msghdr but disables struct cmsghdr while -D_OPEN_SOURCE disables struct
msghdr but disables struct cmsghdr. Please contact socat development if you
know a solution.
Shutting down the write channel of a UNIX domain socket does not seem to
trigger an EOF on the other socket. This makes problems with the exec and
system addresses.
