A little help understanding the runtime compiler source dependency and runtime modifiable include

[Daniel Moodie]

So instead of using my previous hack for compiling cuda code, I wanted to work with the source dependency scheme.

So I have something like this:

DisplayHelpers.h <--- RCC class header

DisplayHelpers.cpp <--- RCC class

DisplayHelpers.cuh <--- cuda header

DisplayHelpers.cu <--- cuda code

I have an interface to my code which works with RCC, it has its own .cpp and .h file.

The DisplayHelpers.h includes a cuda header file "DisplayHelpers.cuh" which has the following:

#include "RuntimeInclude.h"

#include "RuntimeSourceDependency.h"

RUNTIME_MODIFIABLE_INCLUDE

RUNTIME_COMPILER_SOURCEDEPENDENCY_FILE("DisplayHelpers", ".cu");

Now when I edit DisplayHelpers.cu, the file monitor notices the change and attempts to do a recompile. 

However in RuntimeObjectSystem.cpp I'm running into an issue.

My fileToBuild (147) is the DisplayHelpers.cu file, it searches the m_RuntimeSourceDependencyMap (156) for this file.  When it finds that DisplayHelper.cpp depends on DisplayHelper.cu, it renames fileToBuild to DisplayHelper.h (line 160).

Thus the .cu file never gets built because it tries to build 

So I guess I misunderstand the purpose of RUNTIME_COMPILER_SOURCEDEPENDENCY / RUNTIME_MODIFIABLE_INCLUDE, could someone elaborate on what I should do in this situation?

This looks like a bug to me. I'll investigate asap.

I bug reported this here: https://github.com/RuntimeCompiledCPlusPlus/RuntimeCompiledCPlusPlus/issues/80

and fixed it here: https://github.com/RuntimeCompiledCPlusPlus/RuntimeCompiledCPlusPlus/commit/4d05998f6812d82fe59f34c1d311e00314d1fdda

Somewhat ashamed that I let this combo through :( Many apologies.

Let me know if this does / doesn't work for you!

This looks to have fixed it, thank you so much!
