I'm trying to connect over to the C++ package called Awesomium
(http://princeofcode.com/awesomium.php), which is decently small. I've created
the files dawesome.h, dawesome.cpp, and dawesome.di, which you can see at the
bottom of this post. Awesomium's library file was an import library, so I used
coffimplib to convert it. I am using dmc to compile my files, using Digital
Mars' stlport package.
But so when, at the end, I try to compile a full EXE on a test program
(dawesome_test.d), I get some linker errors combining it with my bindings
(dawesome.obj) and awesomium's converted library:
T:\programs\Dawesome>t:\dmd\windows\bin\dmd.exe dawesome_test.d dawesome.obj
awesomium.lib

I'm very new to D and was always more a C guy than a C++ guy, so I'm really not
sure where in the chain I might have gone wrong.
