Hi,

If using Visual Studio you can click "Project>Show all sketch files" this should include the correct lib files in your sketch and will not break compilation. The feature is not yet available in Atmel Studio.

In visual studio and atmel studio you also have various other options or points of interest

1) Intellisense when typing should show the correct values
2) Right click an #include and then click "Goto Implementation" (Alt+G)
3) Right click any code then click "Goto Implementation" (Alt+G)
4) Right click and code then click "Find references"

Hopefully these items help but can you please confirm which Ide you are using so we can explore this some more.

Thanks

Okay in Vs it is F12 to jump to definition but the "include all sketch files" should work well. The class explorer should also only show the correct libraries?

Hi

Because it isn't possible to specify library paths in an arduino project there are certain rules to bear in mind. The entire library system has been overhauled 3 times in the past year by the arduino team so if we can improve visual micro we will.

Here are some things that might help ...

Normally Arduino libraries have a .h file of the same name as a library folder. This makes library resolution much more accurate. For example #include "GSMSHIELD.h". Is there a GSMSHIELD.h in the GSMSHIELD library? You see that all standard Arduino libraries adhere to this rule of a .h and a lib folder being the same. If your lib had a gsmshield.h then the library resolver would find all .h files from the GSMSHIELD library in preference to other libraries. One solution is that you could create an empty .h and include it in the sketch.

The resolver looks for "[sketchbook folder]/libraries" in preference to libraries stored under the arduino ide. This can be used to some advantage sometimes.

Because of this "hole" in the Arduino compiler design Visual Micro also allows you to specify the exact library by preceding #includes with the library name:- 

"libraryName\header.h"
"GSMSHIELD\gsm.h"

The latter suggestion will not work in the arduino ide but gives you complete control. The order of the #includes can also be used to control the resolution of libraries so put your #includes that do not resolve to multiple libraries first or put a fully qualified ("GSMSHIELD\gsm.h") reference at the top so that other .h files can be resolved from the named library.

In short, visual micro does it's best to find library sources but when duplicates exist and a LibraryName.h does not exist then things need a little care and attention.

I hope this makes sense.

gsm is being included because of the #include "gsm.h" in your sketch. 

Every compile re-looks at the includes to establish the build requirement.

It is possible to clear the compiler cache with "Build>Clean Solution" but this is not required and is not the problem. 

The problem is simply that a library folder containing gsm.h is being discovered before the GSMShield folder.

Hopefully my previous post explains ways to resolve the conflicting lib source file names
