[rabbitmq-discuss] Trouble building rabbitmq-c on windows

Wed Dec 15 20:55:23 GMT 2010

Sorry for the noise, I believe I have gotten to the bottom of this.

By default on our systems, we have the $CL var have a couple of default values that were not playing nice. After clearing this var and restarting everything, things look sane.

I got past my initial error by adding spaces to the start and end of my $CL env variable. For some reason mingw didn't like them, while cygwin is fine either way.

Now stuck on this error:
configure:3128: cl.exe -nologo   conftest.c  >&5
conftest.c

LINK : error LNK2001: unresolved external symbol _mainCRTStartup

conftest.exe : fatal error LNK1120: 1 unresolved externals

I can run the command outside of the configure script and get it to succeed, so I am a little baffled.

Thanks,
Paul

Hello,
  I am unfortunately stuck on Windows and C land and am trying to get the rabbitmq-c client built up on windows using the Visual Studio compiler.

First off, this client is marked as experimental. I am curious how experimental this is... for instance, would I be a fool to use this library for production purposes? If so, is there a different recommended library or should I be looking at a different messaging system with better C support?

I am have gone through the README.windows many times and think I understand the steps, but there is some disconnect.

Here are the steps I took:

1)      Grabbed the recommended mingw package using the given install script

2)      Coped rabbitmq-c and rabbitmq-codegen(though I'm not sure what this one does yet) into the mingw directory.

3)      Start up the bash from my new mingw

4)      Verify that python is available and that /bin is in my path for mingw apps (I actually had to add /bin to my PATH)

5)      Ran the mount command as specified: mount 'C:\mingw' /mingw - this succeeds

6)      Enter the rabbitmq-c directory and kick off the build: etc/build-ms.sh

Below are the outputs from the configure run. I have tried this on a Windows7 machine and a WindowsXP machine and in both cases, I got the same results. It looks to me like the command to verify the compiler isn't being run correctly.

Please let me know if there are any ideas.

Thanks,
Paul
