Hi, compiling libol-0.3.16 (and syslog-ng-1.6.8) on HP-UX 11.00/11.11 worked without any problems. Today, I tried to compile libol-0.3.17 (and syslog-ng-1.6.9). I got following errors during 'make': Making all in src make all-am source='io.c' object='io.lo' libtool=yes \ depfile='.deps/io.Plo' tmpdepfile='.deps/io.TPlo' \ depmode=hp /bin/sh /tmp/libol-0.3.17/depcomp \ /bin/sh ../libtool --mode=compile cc -DHAVE_CONFIG_H -I. -I/tmp/libol-0.3.17/src -I. -D_GNU_SOURCE -D_XOPEN_SOURCE_EXTENDED -g -Wall -O2 -c -o io.lo `test -f 'io.c' || echo '/tmp/libol-0.3.17/src/'`io.c cc -DHAVE_CONFIG_H -I. -I/tmp/libol-0.3.17/src -I. -D_GNU_SOURCE -D_XOPEN_SOURCE_EXTENDED -g -Wall -O2 -c io.c -Wp,-M.deps/io.TPlo +Z -DPIC -o .libs/io.o cc: "io.c", line 493: error 1588: "MSG_DONTWAIT" undefined. cc: "io.c", line 493: warning 563: Argument #4 is not the correct type. *** Error exit code 1 Stop. *** Error exit code 1 Stop. *** Error exit code 1 Stop. It seems, that there is no MSG_DONTWAIT variable defined in the socket.h file on HP-UX like for example on SUSE 10.0. It seems, that the reference to MSG_DONTWAIT came new with libol-0.3.17. -- Lust, ein paar Euro nebenbei zu verdienen? Ohne Kosten, ohne Risiko!
