Hello, brothers and sisters help me. See attached for details. I use Windows 7 64bit OS on ASRock Motherboard, MinGW-5.1.6 + MSYS-1.0.11, msysDTK-1.0.1, other windows platform requirements for squid, squid-2.7.STABLE8, and also squid-2.7.STABLE9 it gives stack.o error, Win64OpenSSL_light-1_0_0a from http://www.slproweb.com/products/Win32OpenSSL.html, vcredist_x64, ActivePerl-5.12.2.1202-MSWin32-x64-293621, openssl-0.9.8h-1-setup (i copied some files from lib and include into MinGW lib and include respectively). I am trying to compile squid-2.7.STABLE8 or squid-2.7.STABLE9 with --enable-ssl has one of the options, after the ./configure command and during the make command it gives error. I sent the above message to squidnt@xxxxxxxxxxxxxxxxx, see reply below: You must use a full 32 bit build environment. 64 bit build tools or libraries are not supported (and never developed) on Windows.

The issue now is that i am trying to compile squid-2.7.STABLE8 or squid-2.7.STABLE9 with --enable-ssl option and i got the error (see attachemts). I have tried the compilation on different environmentg x86 or x64 all give the same error i told you before (could not find lssleay32on squid-2.7.8 and stack.o error on squid-2.7.9). I wanted to install another version of openssl say 10.0.0a but couldn't find a suitable binary that could address the problem but i find a clue somewhere http://old.nabble.com/OpenSSL-code-on-Windows-crashes.-td24003641.html and http://openssl.org/support/faq.html#PROG2 that ask me to do the following: To build, I needed to modify the first lines of the example openssl-10.0.0a.tar.gz source code's Makefile as follows: OPENSSLDIR=c:/openssl32 CFLAGS=-g -I$(OPENSSLDIR)/include MD=-Lc:/openssl32/lib -llibeay32 -lssleay32 Honestly, i dont know how to compile openssl talk less of modify any file in it but later i surmon courage to do something. See the attached again for the error message i got when am trying to compile openssl-1.0.0a. SQUID USERS:Please, what can i do to resolve the error ? OR guide me on how to compile squid-2.7.STABLE9 (squid-2.7.STABLE8) with --enable-ssl in a windows 7 x32 or x64 environments. Regards
