Boost Python quickstart examples give error

Question

when i try running the example under C:\boost_1_50_0\libs\python\example\quickstart i get the following error and my python file gets removed ( which is quite annoying ) . I am using Python 3.3 & Boost 1.50 on a Windows 7 OS .

C:\boost_1_50_0\libs\python\example\quickstart>bjam toolset=msvc --verbose-test test > error_log

error_log:

...patience...

        if %ERRORLEVEL% NEQ 0 EXIT %ERRORLEVEL%

...failed msvc.link bin\test_embed.test\msvc-10.0\debug\threading-multi\test_embed.exe

So there are 2 errors here that need to be fixed :

a ) copy test_extending.py The syntax of the command is incorrect.

b ) LINK : error LNK2001: unresolved external symbol _mainCRTStartup

Any ideas how do i fix this ?

No sorry i could never get it to work .. I hope that you add the solution here in case you are able to solve the problem . — rockstar

I'm not sure what the problem is with a). Problem b) appears to be a bug in the boost example, the jam file is trying to make a test executable from an executable instead of a static lib or cpp file.

I documented what I had to do to get the embed example running.
