Hi, I am having a problem moving my boost python extension to a different machine than my development machine. On my development machine everything works great, I can access my C++ classes through python without any problems but when I copy my .pyd (Python_ext.pyd) to my target machine I get the error "DLL Load failed The specified module could not be found" in my Python program when I attempt to import the .pyd (import Python_ext) I am using Boost_1_42. The .pyd was built using BJAM and my compiler is MSVS 2003 and python26. Python26 is on both the development and the target machine. I had similar problem when I moved my python .pyd extension module to a different directory on my development machine but I fixed that by copying the boost dll boost_python-vc71-mt-gd-1_42.dll to the directory with my .pyd module and it ran great there. I tried to do the same thing on my target machine. I copied my python program, the .pyd extension module and the boost DLL (boost_python-vc71-mt-gd-1_42.dll) to the same directory on my target machine and still get the same error. Both machines are windows XP. To test this I am using a simple test C++ class that just receives two numbers and prints out there sum so I do not believe I am bringing in any other dlls. I am sure this is a simple problem and I am just missing it. Any help would be greatly appreciated. Thanks John
