Unable to find library, no such file or directory

[chrisspen]

I'm attempting to compile this simple bounce.ino example with ino, but it's giving me the error:

Bounce2.h: No such file or directory

I've placed it in the same directory as bounce.ino. I still get this error even if I use arduino to add the library to my ~/sketchbook/libraries folder.

Why can't it find the header? How do I specify that the local directory should also be checked for headers? Why can't ino see the libraries in the standard ~/sketchbook/libraries` folder?

:+1: Same here! I've written my own .cpp and .h file in the src directory. ino build tries to compile Car.cpp but throws an error src/Car.cpp:2:17: error: Car.h: No such file or directory.

Is there something obvious that I'm missing?

The .cpp and .h files need to be in the lib folder in a subfolder named the same as the .h and .cpp in order for it to compile.

Ino also scans arduino librairies folder, but I hate to put libs there.... it gets scanned for all projects you make and first time compile is much longer because on that at least for me...

Ok thanks for the clarification. The docs were a little confusing on this:

Here we have two directories. src is a source directory where we can put our project’s *.[c|cpp|pde|h|hpp] source files. sketch.ino was created for us, so we have a starting point. lib is a directory where we may put 3-rd party libraries if we would want.

The class I'm writing is not a 3rd party library. It's source code specific to the project, so I thought it belonged in src

[translucide]

If that can be of any help to you... here is how I work: I put my source code specific libs in project lib folder and symlink to the project lib folder the 3rd party libs from another lib folder i use to put all libs that will not change (3rd party or my general libs that I might use in multiple projects). That way I can maintain some libs for all my projects at the same place without putting them in the damn arduino librairies folder and not seeing them being compiled for nothing when I first compile a new project...

You can fix this issue by adding the following to environment.py at line 73:

lib_dir_extra = os.path.expanduser('~/sketchbook/libraries')

and changing the line in commands/build.py at 249 to:

lib_dirs = [self.e.arduino_core_dir] + list_subdirs(self.e.lib_dir) + list_subdirs(self.e.arduino_libraries_dir) + list_subdirs(self.e.lib_dir_extra)

After putting the library directory in both the lib directory as well as the /usr/share/arduino/libraries/ this was still not working. Did ino clean and then ino build and it worked.
