Are you sure you have g++ installed? Although in fact you need to use gcc not g++ (the source is plain C, and some bits of it aren't compatible with C++ compilers).

If you're getting errors about BSON.h not found, check you have completed this step:
Under the Compiler tab, click Add, and browse to and add the "includes" folder of the source to the list. (It should be okay to leave it as a relative path, but if you get a bunch of errors about various .h files not being found, try using the full path of the includes folder.)

The full path would be something like "E:\Unknown\L\Powder\Mod\ModIWork\PowderCBNoFFTW" (might need "\includes" on the end as well). The preset projects don't use this because they don't know the full path - the path depends on where you extract it to.

For some reason best known to itself, Code Blocks is using g++ to link TPT. If g++ is not installed, compilation will fail with the message "Execution of 'mingw32-g++.exe....' failed"

There are two possible ways to fix this.

A) Install g++: either when you install MinGW, or afterwards by running "mingw-get install g++" in command prompt.

B) Change the linker executable in Code Blocks
In Code Blocks, go to Settings -> Compiler and debugger.
Under the "Toolchain executables" tab, change "Linker for dynamic libs" to mingw32-gcc.exe

Are the files still in that location (E:\Unknown\L\Powder\Mod\PowderCBProj\) ?

If they've been moved, try removing them from the project and adding them again. Otherwise, maybe try starting again with a blank project.

(To remove and re-add: In the Management window you will see the project name listed there. Right-click it, click "Remove files...", and remove all of them. Right-click it, click "Add files recursively...", and choose the folder where all of the files are.)

Under the project name in the Management window:
The only file in Resources should be src/Resources/powder-res.rc
Remove any other files there.


(.res files should be automatically generated from .rc files during the build process)
