Unfortunately, "+" is not a letter in the Roman alphabet, so C++ causes some naming problems.--- End Message --- ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers

[tcpdump-workers] CPPFLAGS in C-only context
--- Begin Message --- Hello all. There is one other thing in Autoconf files of tcpslice and tcpdump that jumped out at me: savedcppflags="$CPPFLAGS" CPPFLAGS="$CPPFLAGS $V_INCLS" AC_CHECK_HEADERS(pcap/pcap-inttypes.h) AC_CHECK_FUNCS(pcap_lib_version) CPPFLAGS="$savedcppflags" It looks like either in a C project context CPPFLAGS works in a non-obvious way, or is a no-op. -- Denis Ovsienko --- End Message --- ___ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
