[stunnel-users] Visual studio compilation errors

Tue Nov 15 20:42:49 CET 2005

Hi,

After browsing all previous list messages I havent found information about
an error I get compiling stunnel with visual studio. The errors appear in
linking step with undefined symbol message: "undefined symbol: LNK2019
undefined symbol _exit_stunnel referenced in function _main_initialize".

I also attach the Makefile.w32 changed to work with visual studio.

Thanks in advance.

Regards,

Jorge.

Makefile.w32 follows:
# Simple Makefile.w32 for stunnel.exe by Michal Trojnara 1998-2000
#
# Modified by Brian Hatch (bri at stunnel.org)

# This makefile is only tested on the mingw compiler. Mingw
# can successfully compile both openssl and stunnel. If you want
# to use another compiler, give it a shot, and tell us how it went.

# Modify this to point to your actual openssl compile directory
# (You did already compile openssl, didn't you???)
SSLDIR=..\..\openssl-0.9.7g

DEFINES=-DUSE_WIN32 -DHAVE_OPENSSL

# You may want to add some of the following flags
# to the DEFINES definition above.

# Location of default certificate file for -v option
# -DCERT_FILE=\"/stunnel/certs/certs.pem\"

# Location of default certificate directory for -v option
# -DCERT_DIR=\"/stunnel/certs\"

# Default directory for stunnel.pem file
# -DPEM_DIR=\"/stunnel/private\"

# Use the default certificate sources from your ssl library? (0==no, 1==yes)
# -DSSLLIB_CS=0
