This page explains how to build on Cygwin packages that are not part of the official Cygwin distribution.
Socat
Socat 1.6.0.1
A port of socat 1.6.0.1 on Cygwin is easily obtained (see [1]).
After untar & cd:
./configure
make
make install
make test
Socat 2.0.0 beta 2
!!! Interaction with McAfee Anti-Virus !!! - McAfee AV detects socat 2.0.0-b2 as a potentially unwanted program, and deletes socat.exe at first execution. To prevent this, open McAfee VirusScan Console → Unwanted program policy → Unwanted program exclusions → click Exlusions... → click Add... → click Browse... → select 'Socat' and then click Ok. This should prevent McAfee AV to detect Socat as an unwanted program.
First install the following packages in Cygwin:
- libwrap-devel (optional - to enable tcp wrappers)
- readline (optional - to enable readline)
- minires, minires-devel (optional - to enable resolver)
The following changes must be made to the build & install procedure:
- Add LIBS="-lresolv" to configure call (note that /lib/libresolv.a is a link to /lib/libminires.dll.a on Cygwin). This is only needed if package minires-devel is installed. In that case, HAVE_RESOLV_H is defined, and without this change, we get the compilation error:
gcc -O -D_GNU_SOURCE -Wall -Wno-parentheses -DHAVE_CONFIG_H -I. -o socat socat.o libxio.a -lutil -lssl -lcrypto -lpthread libxio.a(xio-ip.o):xio-ip.c:(.text+0x24): undefined reference to `___res_init' libxio.a(xio-ip.o):xio-ip.c:(.text+0x51): undefined reference to `___res_state' ...
The build & install procedure:
./configure LIBS="-lresolv"
make
make install
Note that a custom config.h and Makefile for Cygwin can also be found in the directory config/.
Tests can be run, but it needs the following changes to test.sh
--- socat-2.0.0-b2/test.sh 2008-11-16 23:33:09.312500000 +0100
