I’ve compiled Mercurial 1.5.4 for Python 2.6, following this guide, and uploaded it here, since I guess it’ll be useful for later:
mercurial-1.5.4.win32-py2.6.exe
I use it for Trac 0.12 in a multi-repository setting, so we can keep our old SVN repo while having some of the larger projects on Hg.
A quick post today: Using these instructions, I’ve built a statically linked lxml 2.2.4 for Windows.
I used the following versions of the libraries:
1 2 3 4 5 6 | STATIC_INCLUDE_DIRS = [ "..\\libxml2-2.7.6.win32\\include", "..\\libxslt-1.1.26.win32\\include", "..\\zlib-1.2.3.win32\\include", "..\\iconv-1.9.2.win32\\include" ] |
1 2 3 4 5 6 | STATIC_LIBRARY_DIRS = [ "..\\libxml2-2.7.6.win32\\lib", "..\\libxslt-1.1.26.win32\\lib", "..\\zlib-1.2.3.win32\\lib", "..\\iconv-1.9.2.win32\\lib" ] |
Download it here: lxml-2.2.4.win32-py2.6
I found this blog post, Simple Python ctypes Example, on Reddit, and thought I’d see how different the procedure was for Windows.
Create a file dlltest.c with the following content:
1 2 3 4 5 6 7 8 9 10 11 12 | #include <windows.h> BOOL APIENTRY DllMain(HANDLE hModule, DWORD dwReason, LPVOID lpReserved) { return TRUE; } __declspec(dllexport) int multiply(int num1, int num2) { return num1 * num2; } |
Start the Visual Studio 2008 Command Prompt from the Start Menu (this sets up the path for the compiler and other files, which makes things easier) and go to the directory you saved dlltest.c to.
Compile it with the following command:
cl -LD dlltest.c -Fetest.dll
As in the original Linux example, this DLL is easily tested using similar commands:
1 2 3 4 | >>> from ctypes import * >>> libtest = cdll.LoadLibrary('test.dll') >>> print libtest.multiply(2, 2) 4 |
So, that is the simplest DLL possible, I’ll look at (same as the original blog post) applying it to more complex examples later.
