In a project with many .cu files and a .h file, I have some constants defined in my main.cu like this (shown just one as example):
device constant unsigned int x;
… some code…
In the file second.cu I am trying to use that constant, like this:
cudaMemcpyToSymbol(x, y, sizeof(xx));
But Eclipse is giving me the error: identifier “x” is undefined.
I noticed that #includes in my main.cu, like the header.h, I need to specifically add in all the .cu files again. Which produced some redefinition problems that I solved using #pragma once.
I am new to Eclipse in general, found some complains about the CDT regarding include files not being indexed. I tried the Index Rebuild/Update/Freshen/Re-resolve method that worked for some in this regard, but with no luck with my problems.
Also, tried disabling the ‘heuristic resolution of includes’ in Properties -> Indexer. I thought I got it for a few moments but then the error showed up again.
Any ideas to solve this problem?
