Hy Tim,
I have 2 PCs on one I can compile the project attached on the other not.
The files in the Arduino path are identically.

I see no difference between th 2 PCs.
Maybe you know why.


Compiling 'ToolCtrl' for 'Teensy 3.6'
ToolCtrl.ino:14: In file included from
bsp_board_teensy_1.h: 114:37: fatal error: display/Adafruit_FT6206.h: No such file or directory
   compilation terminated

       An error was encountered during the 'Deep Search' library discovery process.
Build failed for project 'ToolCtrl'

Thanks for sending the files in. Here are a few things that might help.

These are primarily Arduino riles, the way it works unless I hear otherwise.

Arduino libraries are never #included with paths

Arduino libraries should always be #included with chevrons not quotes #include <myheader.h>

The .ino files must always be in a folder with the name name as one of the .ino files (not in the src folder (or below) which is for normal c++ files)

Visual Micro also expects the project name and project file name to be the same as the primary .ino and containing folder name. The project must be in the same folder as the .ino

In short I recommend using the Visual Micro menus to add your library includes for you, remove path qualifiers from library includes, move the .ino from \src into the project folder  and make sure the folder, .ino and project names match.

We might support .ino files in sub folders but I don't think the arduino ide does (or never used too) therefore we need to ensure compatibility

The question is, why it runs on machine A but not on machine B.
I have read, that for the comercial version the subfolders are possible.
So i try to kill the Lizense Key on machine B. But no chance. Where to change the Lizense Key?
You know we have had some problems with the Key on crashed PCs.
So if you tell me to delete the Key, I will try for that.

It sounds like the machine that works has different config. The licence key does not provide or restrict any functionality. It is not the issue. The \src folder functionality is a standard part of arduino and visual micro.

There is the vMicro>Compiler menu that contains an entry called "verbose" and an entry called "show build properties". Switching on these options and then building gives output which shows everything about your config and the build. Please switch them on on both machines, build on both then email the outputs as .txt files along with link to this thread.

Also zip and email the project folder from your other machine that works.

Thanks

The project is the same on the old and new machine.

on the new machine I have changed the things you mention.
So it works.

But why it works on the old machine?

You have switched on "show build properties" but haven't switched on verbose.

Thanks

Next try

There are some differences in the project files between the two machines.

Take a look at the ProjectDir= property

The old machine must have the project files in the src folder.

The old machine also has a local project board.txt file but it might be unused and is of no concern.

the ProjectDir is changed like you mention.
this could not be the reason.
I have no idea why.

I guarantee you that the way you had your project setup was outside of the simple rules described earlier and should never have worked. Certainly never in Arduino IDE?

Can you confirm that the board.txt you have in the project folder of old machine is empty?

Yes the board.txt is empty.
Everything was the same.
Also the Arduini path with it's entry.
nevertheless, now I have an version on the new Machine which works.
we wil close this thread.

Thanks for your help
