If you would like to use Codelite on Windows instead of Visual Studio, there's a few things required in order to use for developing Orx projects.
Codelite can be downloaded from: http://downloads.codelite.org
While there you can choose to donate to the project.
The version required must be at least 9.2.0. Although versions like the 6.x series will compile Orx projects fine, you will have problems trying to attach a debugger. So get the specific version or higher.
When installing Codelite and running for the first time, a wizard will appear, giving the opportunity to download a MinGW compiler for you. These are TDM versions, don't download any of these.
Codelite needs a compiler. It doesn't ship with one anymore. But you will need to pick the right MinGW. There are a few variations around:
Since Orx build commit 0e32f26, TDM versions of MinGW can no longer be used. Nor are Mingw-w64 versions supported by Orx as yet.
Therefore, the vanilla version of MinGW is the correct one to use from here on.
At the time of writing, 5.3.0 is the version to use. But to check on the current version requirements, visit the Orx supported platforms here.
Start by downloading the MinGW installer at: https://sourceforge.net/projects/mingw/files/latest/download
Run the installer and go through the steps. These are outlined on this page: http://orx-project.org/wiki/tutorials/compiling_orx_with_mingw32_gmake
Follow the steps titled Getting mingw32 and Updating the PATH environment variable.
You're all good to go.
