I am trying to build the tutorial example showing how to call a c++ function from a python script. When I run bjam I get the following message. I am using MSVC++ 2005 Express Edition.

Is the compiler in your path? You can either use the Visual Studio Command Prompt or call vsvars32.bat explicitly. In Christ, Steven Watanabe

In almost every case that should make no difference at all; Boost.Build's msvc toolset is designed to do that for you if necessary. It might be instructive to add --debug-configuration to the bjam command line, though. -- Dave Abrahams BoostPro Computing http://www.boostpro.com

Ok. I found the solution using msvc : 8.0express ; just saying 8.0 doesn't work. Grrr. In Christ, Steven Watanabe

Hi Tony.

...

I don't know how to specify new directories in the include path using bjam.

Use the <include> feature, e.g. from the command line you do it like this: bjam include=/xxx/yyy/zzz but you usually want to do such things from inside your Jamfile. Best regards, Jurko Gospodnetić

The .pyd file is the DLL. Python uses a different naming convention for DLLs used as extension modules. -- Dave Abrahams BoostPro Computing http://www.boostpro.com

Tony, Sorry I can't lead you through the steps here right now. I suggest you post this question on the C++-sig (http://www.boost.org/community/groups.html#cplussig), where more people, who may have more time than I do, know the answers. Better yet, this isn't really a C++-specific question, so you might try the comp.lang.python newsgroup. -- Dave Abrahams BoostPro Computing http://www.boostpro.com

Hi Tony.

...

I am trying to build the tutorial example showing how to call a c++ function from a python script. When I run bjam I get the following message. I am using MSVC++ 2005 Express Edition.

C:/Program Files/boost/boost_1_35_0/tools /build/v2/tools\msvc.jam:263: in confiure-really *** argument error * rule path.make ( native ) * called with: ( ) * missing argument native C:/Program Files/boost/boost_1_35_0/tools/build/v2/util\path.jam:42: see definiton of rule 'make' being called

What I find real strange here is that your log states 'confiure' instead of 'configure'. Where did this typo come from? Boost Build coming with Boost 1.35.0 release does not have it. What version of Boost Build are you using?

...

I created a user-config.jam file in my home directory. Its contents are below.

# MSVC configuration using msvc : 8.0 ;

# Python configuration using python : 2.5 : C:/Program Files/Python25 ;

One thing that could likely go wrong with this is that the python path you listed contains spaces but you do not quote it. You should most likely rewrite that last line as:

...

using python : 2.5 : "C:/Program Files/Python25" ;

Hope this helps. Best regards, Jurko Gospodnetić
