I'm going to re-ask a question belonging to this post https://stackoverflow.com/questions/12418452/source-files-in-project-subfolder-not-compile-qnx-momentics-ide because I'm having the exact same issue and after google it for several hours/days/.. I'm not finding any help and the thread I mention before wasn't answer by anybody, I hope not to get the same luck.
I'm going to explain the issue: I'm developing right now for Blackberrys new O.S. BB10, which recommends the QNX Momentics IDE for developing in C/C /Qt/QML etc. The IDE, as is said in a comment in the thread above, is a re-package/bundle of Eclipse with the Eclipse CDT plugin and some custom QNX tool extensions. The thing is that when I'm trying to organize my code files into subfolder in the main src folder, those files will not compile, wich keep the program from running successfuly obviously. Please if you know why this is happening give me a hand :) .
I've found some sites about Eclipse where they said that I need to add the subfolders to the "path and symbols" settings of the project. And I did that, and nothing seems to change. I also tried to create a new src foulder instead of a regular folder, but when I'm trying to do it I get the following error: Invalid project path: Duplicate path entries found.
So fellows this is driving me crazy, I have like 50 C classes in the root src folder right now. Help please!.
Greetings!..
