Greetings, After a fair amount of troubleshooting and searching archives/mailing lists/net I have grow weary. I am attempting to build squid 2.6 from src's on a Windows XP pro system. Below is the configure line and the build output around where the build fails. I am using mingw/minsys as a build environment per the instructions found on the acmeconsulting website. Many thanks ... ./configure line: ============================ ./configure \ --enable-win32-service \ --enable-htcp \ --enable-icmp \ --disable-wccpv2 \ --disable-wccp \ --enable-underscores \ --enable-storeio='ufs null' \ --enable-removal-policies='heap lru' \ --enable-snmp \ --enable-win32-service \ --enable-useragent-log \ --enable-referer-log \ --enable-auth='basic' \ --enable-basic-auth-helpers=NCSA \ --with-maxfd=8192 \ --enable-err-languages=English \ --prefix=c:/TotalControl/squid/ Build output: ============================ make[1]: Entering directory `/home/xoneill/squid-2.6.STABLE4-NT/helpers' Making all in basic_auth make[2]: Entering directory `/home/xoneill/squid-2.6.STABLE4-NT/helpers/basic_auth' Making all in NCSA make[3]: Entering directory `/home/xoneill/squid-2.6.STABLE4-NT/helpers/basic_auth/NCSA' gcc -Wall -g -O2 -mthreads -o ncsa_auth.exe ncsa_auth.o crypt_md5.o -L../../../lib -lmiscutil -lpsapi -lws2_32 ncsa_auth.o(.text+0x3d6): In function `main': C:/msys/1.0/home/xoneill/squid-2.6.STABLE4-NT/helpers/basic_auth/NCSA/ncsa_auth.c:143: undefined reference to `crypt' make[3]: *** [ncsa_auth.exe] Error 1 make[3]: Leaving directory `/home/xoneill/squid-2.6.STABLE4-NT/helpers/basic_auth/NCSA' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/xoneill/squid-2.6.STABLE4-NT/helpers/basic_auth' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/xoneill/squid-2.6.STABLE4-NT/helpers' make: *** [all-recursive] Error 1
