I have a following include in my C source file (of a kernel module)
#include <linux/regmap.h>
Is there any way to quickly open this file in Atom?

I bought this NFC Shield for my Arduino controller.

I downloaded and installed this library as instructed from GitHub
https://github.com/Seeed-Studio/PN532
But when I include the library I get an error:
Code:
include "PN532_SPI.h"
Error message:
ResolveLibrary(PN532/PN532/PN532Interface.h)
In file included from D:\OneDrive\Ardruino\NFC Reader\Seeed\Example Code\2020-05-14\2020-05-14.ino:1:0:

include "PN532/PN532/PN532Interface.h"
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
What could be the problem? Please help?
I managed to fix it.
One has to open each and every file in the library and remove the path PN532/PN532_SPI/
So just the file name included must remain, with no path.
So all the .cpp and .h files
Open all .cpp and all .h files in the library and edit them...
Notepad does not format the files correctly, I had to use Visual Studio to edit the .h and .cpp files.
I'm new to arduino, I'm supposed to add tinyGPS.h but locally, but where is "locally"
line of code:
#include "./TinyGPS.h" // Use local version of this library
I've tried copy and pasting the tinygps.h in whatever arduino folder I could under the belief ./ is in the root of the working directory.
I expected the code to compile.
It means in the same directory as the source file in which you wrote #include.
I want to build an opencv project using Qt 5.1_VS2010. I have included the path for opencv include files. But when I run the code, I get the error that specific .hpp file does not exist! I have checked in the directory and it actually exists there! another point that when I was trying to include it in my main c++ file, the auto completion guide actually helped me complete the whole path! so it means the directory and the header file was already recognized! anyway, part of my .pro file that includes the path is like this:
INCLUDEPATH += "C:/opencv/build/include"
I am using IAR Embedded workbench 5.51 for MSP430. I am using C99.
I am trying include code from a third party library. I have copied the directory structure of this third party library exactly within a sub-directory in my main project directory. However, when I try to compile I get a bunch of
Fatal Error[Pe1696]: cannot open source file "ThirdPartyLib/Subdir/file.h"
However in the log IAR shows:
searched: "C:\ ... bla bla bla ... \Source\ThirdPartyLib\Subdir\"
The include statements in each of the source files in this library are all like:
#include "ThirdPartyLib/Subdir/someheader.h"
I have attempted to add the path to the C preprocessor by going to:
Project -> Options -> C/C++ Compiler -> Preprocessor
and adding the lines:
$PROJ_DIR$\ThirdPartyLib\
$PROJ_DIR$\ThirdPartyLib\Subdir\
$PROJ_DIR$\ThirdPartyLib\Utils\
I do not have "Multi-file Compilation" checked.
All of the source files in question have been added to the project. I have created groups to mimic the directory structure of the library.
The problem goes away if I change the paths from absolute paths to relative paths such as
#include "somelocalheader.h"
#include "../Utils/someotherheader.h"
But I am dealing with a large number of files and want to modify them as little as possible.
I have never had an issue with this before - does anyone have any idea why this would happen. Is there a simple fix for this so I do not have to scrub every include statement in every c file?
This is essentially what my directory tree looks like:
Source
Debug
Exe
Output.d43
List
blabla.map
Obj
...
Release
...
settings
...
ThirdPartyLib
Subdir
... Third Party Code Files Live Here ...
Utils
... More Third Party Code Files Live Here ...
... My Code Lives Here, Along with the EWP, EWW, etc ...
EDIT #2:
I moved the directory of ThirdPartyLib up a level, because I run doxygen recursively on /Source/ and I realized that it takes doxygen FOREVER, and plus the library has its own API.
Anyway, here is what the structure looks like now:
Working Copy
Source
Debug
Exe
Output.d43
List
blabla.map
Obj
...
Release
...
settings
...
... My Code Lives Here, Along with the EWP, EWW, etc ...
ThirdPartyLib
Subdir
... Third Party Code Files Live Here ...
Utils
... More Third Party Code Files Live Here ...
I have added a group back to my project for ThirdPartyLib with two subgroups SubDir and Utils, and added all of the files from the Subdir and Utils directories to the corresponding subgroups.
Now I have tried to compile this again, and again i am faced with the Pe1696 errors. IAR says:
searched: "C:\...\Working Copy\ThirdPartyLib\SubDir"
Yet it is still not finding the files.
I referred to this post:
http://e2e.ti.com/support/low_power_rf/f/155/t/110195.aspx
I am not sure it is completely relevant, because the directories I am including don't seem to have 'fallen out'. IAR is clearly searching for the files.
But I tried anyway to add the following lines to the preprocessor
$PROJ_DIR$\..\ThirdPartyLib\SubDir
$PROJ_DIR$\..\ThirdPartyLib\utils
This does not seem to help. I get these additional lines in the message log:
searched: "C:\...\Working Copy\Source\..\ThirdPartyLib\SubDir\"
searched: "C:\...\Working Copy\Source\..\ThirdPartyLib\Utils\"
Edit #3
I tried moving the EWW/EWP up a level to "Working Copy" and then readded all of the groups and all of the files... no dice. I am lost here. The part that is most frustrating is that the same library is implemented in another project that was done by some former developers and I am trying to include it the same way. I know this is going to be something trivial, I just don't know what.
If all of the #include references inside the library are of the form #include "ThirdPartyLib/Subdir/file.h", then the root directory where ThirdPartyLib is located should be in the preprocessor include path.
If your directory structure is:
C:\My Project\Source
\ThirdPartyLib
then C:\My Project would be expected to be in the preprocessor include path.
When the compiler searches for include files it will join in turn, each of the include search paths with the path listed in the #include directive until a matching file is found.
I have a custom board that uses ATmega168PV, and I have a bin file that when I use Atmel Studio 6.0, I can program it to my board.
I have the source code for the binary (in the format of sketch), and I want to change/compile the code and program the board with them.
I can open my *.ino file in Arduino IDE and it is verifying it and says that
Binary sketch size: 12,096 bytes (of a 32,256 byte maximum)
but I searched the folder that files exist and I could not find any binary file.
How can I compile the code using Arduino IDE?
Build process
Sketches are compiled by avr-gcc.
The include path includes the sketch's directory, the target directory (/hardware/core//) and the avr include directory (/hardware/tools/avr/avr/include/), as well as any library directories (in /hardware/libraries/) which contain a header file which is included by the main sketch file.
When you verify a sketch, it is built in a temporary directory in the system temp directory (e.g. /tmp on the Mac). When you upload it, it is built in the applet/ subdirectory of the sketch's directory (which you can access with the "Show Sketch Folder" item in the "Sketch" menu).
The .c and .cpp files of the target are compiled and output with .o extensions to this directory, as is the main sketch file and any other .c or .cpp files in the sketch and any .c or .cpp files in any libraries which are #included in the sketch.
These .o files are then linked together into a static library and the main sketch file is linked against this library. Only the parts of the library needed for your sketch are included in the final .hex file, reducing the size of most sketches.
The .hex file is the final output of the compilation which is then uploaded to the board. During a "Verify" the .hex file is written to /tmp (on Mac and Linux) or \Documents and Settings\\Local Settings\Temp (on Windows). During upload, it's written to the applet sub-directory of the sketch directory (which you can open with the "Show Sketch Folder" item in the Sketch menu).
Do a file search in your temp folder for *.cpp.hex
