I have a few headers and source files which I want to be common between two sketches (as they are communication interfaces) but I can't include them in my sketches: this very arguable system of tabs refuses to find them when I use relative paths.
Example:
Project
-interface.h
-interface.cpp
-sketch1
--sketch1.ino
-sketch2
--sketch2.ino
I would like to do:
#include "../interface.h"
Without making a library out of it and putting it elsewhere (so as not to have to move around files when they are handed out to somebody else).
Thank you for your help (I'm growing mad over here ),

P.S: Version is 1.0.5 on Windows
The bad news is you probably have to place interface.h/c in a library folder. The good news is that it is not that difficult. Simply create a folder named "interface" as a peer to other library folders and cut/paste interface.h/c into that folder.
Finally, after creating the new folder/lib you will need to completely exit Arduino's IDE and restart it, before you can select a new "interface" lib for your sketch.
Create symbolic links to all of the required files.
Linux
ln -s sourcefile targetfile
Windows
mklink targetfile sourcefile

we working on a C++/CMake project, that needs to run in both Windows and Linux. On Windows, we have to work with a number Visual Studio versions, both in 32- and 64 bit. In order to alleviate dependency issues in our team, we have manually compiled a number of dependencies for each configuration(vs2013_x64, vs2013_x86, vs2012_x64, vs2013_x86...) and installed them (using make install or similar commands) to a common folder for each configuration. Now we have a folder called "vs2013_x64" for example, that contains similar folders as /usr would on linux: CMake, include, lib, share, ...
Now my question is: How do I have to set up CMake, so that it treats this vs2013_x64 folder just like it does /usr on Linux?
I found a number of variables that seem related, for example
CMAKE_FIND_ROOT_PATH and CMAKE_SYSROOT. However, setting them to my vs2013_x64 folder for example does not work: FindXXX.cmake files in the vs2013_x64/CMake folder are not found, and even when I manually set the CMAKE_MODULE_PATH to that CMake folder, the Find* scripts are unable to find the include they are looking for, because the vs2013_x64/include folder does not appear to be searched.
A solution that did work was to set the CMAKE_PREFIX_PATH. This is nice and almost what I need, but lets say that on Linux, I would not want it to look at /usr at all under any circumstances. This would not be possible using the PREFIX_PATH solution if I understand it correctly.
From what I understood from the documentation,
CMAKE_FIND_ROOT_PATH is more configurable and has a number of additional variables such as CMAKE_FIND_ROOT_PATH_MODE_PROGRAM, CMAKE_FIND_ROOT_PATH_MODE_LIBRARY and CMAKE_FIND_ROOT_PATH_MODE_INCLUDE. This makes me believe that FIND_ROOT_PATH is what I actually SHOULD be doing - yet I am unable to make it work
Does what I am trying to do make sense? Can anyone clarify when and how to use what? Ideally, I would like a solution that allows me to set the search path to my vs2013_x64 folder on Windows, that defaults to /usr on Linux, but can optionally also be set to another directory containing lib/include/cmake folders. In addition, it would be nice if searching ONLY occurred in the configured path and nowhere else (to avoid mistakenly picking a library that was installed system-wide).
Thanks!
According to Apple's Developer Docs the Library global allows one to import compiled scripts so they can be used as a library in one's current script. This works just fine if you were to do something like the below code with myLibName.scpt located at ~/Library/Script Libraries:
myLib = Library('myLibName');
myLib.myLibMethod() // Works just fine
But, the docs also claim that one can export an environment variable — OSA_LIBRARY_PATH containing a string of : delimited paths — and Library() would then defer to that list of paths before proceeding to it's default path: ~/Library/Script Libraries. Ya know, like the bash environment variable Path. Here's the relevant piece of documentation below; it describes the path hierarchy:
The basic requirement for a script to be a script
library is its location: it must be a script document in a “Script
Libraries” folder in one of the following folders. When searching for
a library, the locations are searched in the order listed, and the
first matching script is used:
If the script that references the library is a bundle, the script’s
bundle Resources directory. This means that scripts may be packaged
and distributed with the libraries they use.
If the application running the script is a bundle, the application’s bundle Resources
directory. This means that script applications (“applets” and
“droplets”) may be packaged and distributed with the libraries they
use. It also enables applications that run scripts to provide
libraries for use by those scripts.
Any folders specified in the environment variable OSA_LIBRARY_PATH. This allows using a library
without installing it in one of the usual locations. The value of this
variable is a colon-separated list of paths, such as /opt/local/Script
Libraries:/usr/local/Script Libraries. Unlike the other library
locations, paths specified in OSA_LIBRARY_PATH are used exactly as-is,
without appending “Script Libraries”. Supported in OS X v10.11 and
later.
The Library folder in the user’s home directory, ~/Library.
This is the location to install libraries for use by a single user,
and is the recommended location during library development.
The
computer Library folder, /Library. Libraries located here are
available to all users of the computer.
The network Library folder,
/Network/Library. Libraries located here are available to multiple
computers on a network.
The system Library folder, /System/Library.
These are libraries provided by OS X.
Any installed application
bundle, in the application’s bundle Library directory. This allows
distributing libraries that are associated with an application, or
creating applications that exist solely to distribute libraries.
Supported in OS X v10.11 and later.
The problem is that it doesn't work. I've tried exporting the OSA_LIBRARY_PATH variable — globally via my .zshrc file — and then running a sample script just like the one above via both the Script Editor and the osascript executable. Nothing works; I get a "file not found" error. I found this thread-where-the-participants-give-up-hope online; it doesn't explain much. Any thoughts?
On a somewhat related note, the Scripting Additions suite provides two other methods — loadScript and storeScript — that seem like they might be useful here. Unfortunately, when you try to use them, osascript gives you the finger. Though, I did manage to return what looked like a hexadecimal buffer from a compiled script using loadScript. Anyway, any insight you guys can shed on this would be much appreciated. Thanks.
The OSA_LIBRARY_PATH environment variable is ignored by restricted executables when running with System Integrity Protection enabled.
To workaround this limitation you can either turn off SIP, or you can use an unrestricted executable.
For instance, to make osascript unrestricted, you should first make a copy, and then re-sign it with an ad-hoc signature:
cp /usr/bin/osascript ./osascript
codesign -f -s - ./osascript
Once you have the unrestricted osascript, you can run it with the OSA_LIBRARY_PATH environment variable set like this:
OSA_LIBRARY_PATH="/path/to/libs" ./osascript path/to/script.scpt
As a lousy alternative, you can put a symlink at one of the "Script Libraries" folders that osascript would look at and point it to the folder you want. Note that the symlink must be a replacement for the entire folder, it can't just exist inside of it.
rm -rf ~/Library/Script\ Libraries
ln -s "/Your/Custom/Path/Goes/Here/" ~/Library/Script\ Libraries
Tested on 10.13.2
I have a few sketches I'd like to distribute together. All of them use a custom library which resides in the same folder. The current directory structure is totally flat. All .ino files are in a single folder, right next to the .cpp and .h files for the library. This makes it easy to distribute and update.
This would work perfectly, except that each time I open one of the sketches to upload, the Arduino IDE forces me to move it into a subfolder, then it can't find the custom library. Is there any way to disable this behavior, or can anyone suggest a workaround? Thanks!
I tried at first to do all flat and found it never ending battle. Rather than always working around that, I work with it. My example.
Where I have my local repo in some arbitrary location, then have symbolic links in the ./arduino/library/. directory pointing to them appropriate directories in the repo. In the example I have symbolic links for both SdFat and SFEMP3shield in the ./library/. directory. I use windows so rather than links (or the ln -s command) I use "hard junctions".
Note the libraries use a directory structure of ./ardunio/library/foo/example/bar/bar.ino. So I actually do all my projects in the ./example/bar/bar.ino sketch. Also its worth noting that I use an external editor (like notepad++).
This way my repo can have more or less of what I specify it to.
I'm working on a cross-platform Qt application and the paths are different on Mac OS X and Windows. Since the project is on an external hard-drive, the drive letter also occasionally changes on Windows.
For that reason, I would like to refer to the project directory using a variable, preferably a built-in one. In particular, is there such a variable usable in:
The .pro file?
The build settings (in the Projects tab)?
To complete, #Bill's answer, the way to refer to the source path in the Build Settings is to use %{sourceDir}.
%{buildDir} is also available.
Since I struggled a bit to find it, I'm adding it here.
In addition to %{sourceDir} and %{buildDir}, you could use %{CurrentDocument:Path}, %{CurrentDocument:FilePath} and %{CurrentProject:Path} to refer to specific files and folders in the project directory.
The built-in _PRO_FILE_PWD_ variable contains the path to the directory containing the project file in use. That variable may be useful for you.
There are problems with $$_PRO_FILE_PWD_ on windows, because it contains forward slash allways. You need to fix slash using shell_path.
$$shell_path($$_PRO_FILE_PWD_)
I'm having an issue with linked Resources in Flash Builder. I work in a team environment where we use Linked Resources extensively. We just started developing ANEs and noticed that while linkedResources are used in the libraryPathEntry, in the buildTargets like anePathEntry and airCertificatePath, the absolute path is stored. I tried editing the .actionScriptProperties files directly, modifying the buildtarget absolute paths to linked resource equivalents using the libraryPathEntry as a guide but FlashBuilder complained when loading the project.
Is there a way to get the buildTargets to respect linkedResources and not save the absolute path? I'm trying to avoid the draconian way where all developers must have the exact same directory structure.
Thanks!

My team had this exact problem and all attempts to fix it with relative paths or workspace macros (i.e. ${PROJECT_LOC}) failed. It seems as if the team in charge of Flash Builder neglected to support relative paths in these particular dialogs, despite them being supported elsewhere.
Here is what we have done to fix this problem. I am assuming you are on a Mac/Linux or the like. If not, the concept here can still be applied.
Most of our projects already have a "set up" bash script that contributors run when they get code. Inside of that script, we simply set up a couple of symbolic links from the user specific absolute path, to a new absolute path with a "common" user. The script first creates the directory if it does not exist, and then creates the symlinks.
sudo mkdir -p /Users/common/<project>/
sudo ln -f -h -s ~/path/to/certificate/dir /Users/common/<project>/certificates
Obviously you can use whatever you like and whatever makes sense for the common path.
Now, in your .actionScriptProperties file you can change the location pointed to by the provisingFile and airCertificatePath to this new common absolute path.
<buildTarget ... provisioningFile="/Users/common/<project>/certificates/provisionfile.mobileprovision" ... >
<airSettings airCertificatePath="/Users/common/<project>/certificates/cert.p12" ... >
We actually take this a step further (and I suspect you will need to also) and create common symlink paths for the ANE files themselves. This ends up changing the anePathEntry to the common path as well.
<anePathEntry path="/Users/common/<project>/anes/some.ane"/>
You will need to make sure that you either hand edit the .actionScriptProperties file directly, or type in the fully qualified symlink path into the dialogs directly. Any attempt at using the Finder dialog launched by Flash Builder to navigate to the files in the common location resulted in the symlinks being auto-resolved to their actual locations.
The script requires sudo, which as I'm sure you know, will require that the users of it know their root password. Maybe some more bash savvy folks can suggest a way around sudo if this is not an option for you.
This will work for android stuff as well I believe. I don't know if that matters to you or not.
Hope this helps!
It looks like this issue was called out in the Flash Builder 4.6 known issues:
