Hello,

My environment: Windows 8 running WMQ v7.5.

Goal: To compile the samples (I know the sample program binaries are included - am trying to compile from command line so I can make changes to the samples).

What I have done:
I downloaded MinGW and tried to get gcc to work. Had multiple issues to get gcc recognize the MQ libraries. Researched mqseries.net and learnt horror stories of using "non IBM recommended" compilers. Lesson learnt. Upon further digging, learnt MS Visual Express C/C++ compiler is a good option (ie supported compiler)

Downloaded MS Visual Express 2013. Though all I needed was the commandline C/C++ compiler, endured all the crap (.NET 4.5, SQL Server etc etc) that came as a bundle (took 2 hours to download). The installable by default installed the compiler in c:\Program Files (x86)\Microsoft Visual Studio 12.0\VC. When I try to compile using the "CL" command (am basically a commandline guy - do not fancy the IDEs), had issues getting it to recognize the include files.

Also the commadline command with spaces enclosed in quotes again did not work - mainly due to the spaces. Copied the VC folder under c:\Program Files (x86)\Microsoft Visual Studio 12.0\VC into a separate folder (c:\MyCCompiler\VC) - this time without spaces. Got around the spaces issue.

Next the CL command was unable to find the include files. Solved it using the /I switch.

Next came the libraries - mqm.lib. Included this by listing the libs at the end of the compile command. At this point the linker start complaining about the default libraries - LIBCMT.lib, OLDNAMES.lib and finally kernel32.lib! At this point, my commandline compile command looked like this:

LINK : fatal error LNK1104: cannot open file 'kernel32.lib'

===========

Am unable to figure why kernel32.lib is entering the picure as I am essentially building a 64 bit App. Also shouldn't there be a simpler way of linking the standard libs instead of listing every one of those at the end (I can understand the need to have mqm.lib listed - but the rest???)

Folks - can any one guide me as to how to go about this? Will continue to dig but if someone has already been there, done that, would appreciate a shout-out...this started out a simple task but morphed into a complicated exercise (maybe am getting stupider as time passes!)
