security/nmap & gcc3.3?

[Charles Swiger]

Hi, all--

On a FreeBSD-4.9 system, nmap-3.50 builds fine using the stock cc (gcc 
version 2.95.4 20020320), but fails using gcc33 (version 3.3.3 
20040126):

	====

I would gather that nmap is setting the linking path in a fashion which 
causes the gcc33 version of libstdc++ to not be found, or to not be 
linked in by default?

Retrying the linking stage by hand as follows produces a working binary:

58-sec# /usr/local/bin/g++33  
-L/usr/local/lib/gcc-lib/i386-portbld-freebsd4.9/3.3.3/ 
-L/usr/local/lib  -rpath=/usr/lib:/usr/local/lib -L/usr/lib -Lnbase 
-Lnsock/src/  -o nmap main.o nmap.o targets.o tcpip.o nmap_error.o 
utils.o idle_scan.o osscan.o output.o scan_engine.o timing.o charpool.o 
services.o protocols.o nmap_rpc.o portlist.o NmapOps.o TargetGroup.o 
Target.o FingerPrintResults.o service_scan.o NmapOutputTable.o -lm  
-lssl -lcrypto -lnbase -lnsock -lpcre -lpcap -lstdc++

[ Other ports I've tried which use g++33 link fine; this problem seems 
specific to security/nmap... ]
