    copied!<p>I can load Python modules (.py, .pyc, .pyd) from a zip file by calling "import some_module" from a Python interpreter only after sys.path has been extended to include the zip file and only after I have run</p> <pre><code>import zipextimporter zipextimporter.install() </code></pre> <p>The latter is required for .pyd modules.</p> <p>I can also load Python .py and .pyc modules from Python embedded in C++. However, in order to also load .pyd modules from embedded Python I added</p> <pre><code>PyRun_SimpleString("import zipextimporter"); </code></pre> <p>The C++ exe runs beyond this line without error. But the next command</p> <pre><code>PyRun_SimpleString("zipextimporter.install()"); </code></pre> <p>gives me this error:</p> <p><img src="https://i.stack.imgur.com/3iYeR.png" alt="enter image description here"></p> <p>Why does zipextimporter.install() crash when Python is embedded?</p> <p>How can I solve this? </p> <p>Does it perhaps have to do with the way the C++ code is compiled? I use g++:</p> <p><code>g++ embed-simple.cpp -IE:\Python27\include -LE:\Python27\libs -lpython27 -o embed-simple</code></p> <p>I saw a link <a href="https://stackoverflow.com/questions/3402252/how-to-link-against-msvcr90-dll-with-mingw-gcc">How to link against msvcr90.dll with mingw gcc?</a></p> <p>Could that provide a solution? If yes, how should I adjust it, gcc-->g++, since I am running C++ code, not C.</p> <p>I am running Python 2.7.2 on WinXP.</p> <p>I don't get the runtime error after a clean install of Python 2.7.2, just this:</p> <blockquote> <p>Import Error: No module named....</p> </blockquote> <p>Would it matter the way the embedding C++ script is compiled? I used g++. I also compiled with the Intel compiler, but that gave the same runtime error. Perhaps I should try MS Visual C++. </p> <p>Or use ctypes to import the pyd?</p>
