Ive been having the "No such file or directory" issue for quite some time in PlatformIO extension with VScode when its never been an issue in Visual Studio. (not VScode)
My project setup is as follows:
MyProject
|--include
| |--config.h
|--lib
| |--LibraryA
| | |--libraryA.h
| | |--libraryA.cpp
| |--LibraryB
| | |--libraryB.h
| | |--libraryB.cpp
|--src
| |--main.cpp
Now, if I include config.h in main.cpp all is well. But if I include config.cpp in LibraryA/B.h or LibraryA/B.cpp I get the "No such file or directory" compiling error.
Why is this? If I right click #include "config.h" and select "Go to References" it takes me to the config file, or I can "Tab" autocomplete when typing in config.h it does so successfully too. So it knows the header file exists. Why can the linker not find it?
Any help would be greatly appreciated.
Thank you
I finally found the solution. All files in src and include folders are not global. The linker cannot know of the existence of these files, even if intellisense (which is not the same as the linker - which is not the same to the compiler) knows its reference.
To solve this problem add the following line to the platform.ini file.
build_flags = -I include
This will make the content of the include folder visible

EDIT: Answered, below.
Also: If you are reading this you are probably new to web dev and you should consider using webpack for this instead of babel alone
I have what seems like a very simple problem but I can't solve it.
I have a directory structure
Project
|
+-- scripts
|
|
+-- src / src.js
|
|
+-- compiled / compiled.js
And I have been trying to get the following command to work when my terminal is located in the scripts folder.
C:\Users\me\JavaScriptProjects\survey\scripts>npx babel ./src/src.js --out-file ./compiled/compiled.js presets=env,react --watch
But it simply keeps returning:
C:\Users\me\JavaScriptProjects\survey\scripts>npx babel ./src/src.js --out-file ./compiled/compiled.js presets=env,react --watch
presets=env,react doesn't exist
I have tried permutations of removing the ./, replacing it with only /, going into src dir and replacing src/src.js with src.js and then doing ../compiled/compiled.js and many other permutations, but it just keeps saying it doesn't exist.
Even if I add both files to the same directory it's giving the same error.
Most annoying part is it was working fine yesterday.
Thanks in advance.
Solved.
The following has worked from within the src dir after trying for around an hour. I don't know what I've done differently, would love it if someone can point it out.
Thanks.
C:\Users\me\JavaScriptProjects\survey\scripts\src>npx babel src.js --out-file=../compiled/compiled.js --presets=env,react --watch
It could be that you have a babel.config.json file in the \scripts\src folder and that if you move to the \scripts folder to run npx, then it can't see the config file and so doesn't see react.

I'm currently working on an embedded C project in Eclipse, cross-compiling to an M4 Cortex target. This project will create 3 separate executable files: apple.hex, orange.hex, and pear.hex. The "apple" source directory compiles, builds, and links without any dependencies on "orange" or "pear". The "orange" source directory also compiles, builds, and links without any dependencies.
However, "pear" needs to access numerous .h and .c assets from "orange". I've had many attempts at getting my CMakeLists.txt to "find" and "link" the code from "orange" to "pear", but to no avail.
Here is my current CMakeLists.txt file:
cmake_minimum_required(VERSION 3.0)
file(GLOB LD_FILE *gcc_nrf52.ld)
set(MY_APP_DIR ${CMAKE_SOURCE_DIR}/apps/orange)
create_application(
NAME
"pear"
PLATFORM
target
INCLUDE_DIRS
./
${MY_APP_DIR}
LINKER_SCRIPT
${LD_FILE}
SOURCES
${MY_APP_DIR}/foo.c
${MY_APP_DIR}/foo_bar.c
main.c
LIBRARIES
SomeLib_1
SomeLib_2
SomeLib_3
)
However, the compiler keeps complaining, saying that it cannot find "foo.h" and "foo_bar.h".
1) Do I need to separately create a static library in orange in order to access it in pear?
2) If I don't need to create a static library to access orange from pear, how do I link orange to pear?
3) I cannot find where CMake places the object files. Where are they?
This project is all under a single makefile.
Any help would be greatly appreciated, thanks!
I was able to fix my directory issues so that all of the include directories in ${MY_APP_DIR} are being linked into "Pear". However, a new issues has arisen. The linker cannot find the map file needed to create the executable image:
/usr/local/Caskroom/gcc-arm-embedded/5_4-2016q3,20160926/gcc-arm-none-eabi-5_4-2016q3/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld: cannot open map file /Users/admin/Github/target/apps/pear/pear.map: No such file or directory.
I'm not sure why a map find isn't being created. Is the linker (ld) still missing files?
I'll try to answer your questions
You are not linking your libraries to your target.
You need something like:
$target_link_libraries(yourtarget yourlibraries)
after your add_executable command.
3) I cannot find where CMake places the object files. Where are they?
CMake puts all of its outputs in the build tree by default, so unless you are liberally using ${CMAKE_SOURCE_DIR} or ${CMAKE_CURRENT_SOURCE_DIR} in your cmake files, you should find the output files in the folder where your CMakeLists.txt file is.
I am trying to program the Arudino Nano from Eclipse. It has the same processor as the Uno (Atmega328p). I have had this working before with the Uno, but have since gotten a new hard drive and had to reinstall/reconfigure everything. I am running Fedora 19 with Eclipse Kepler. I am getting an error in the build process that I don't even know where to start looking to solve, and Google hasn't been much help...
Here is the error:
make all
Building target: Arduino_Template.elf
Invoking: AVR C Linker
avr-gcc -Wl,-Map,Arduino_Template.map -mmcu=atmega328p -o "Arduino_Template.elf" ./Analog.o -l/usr/avr
/usr/lib/gcc/avr/4.8.2/../../../../avr/bin/ld: cannot find -l/usr/avr
collect2: error: ld returned 1 exit status
make: *** [Arduino_Template.elf] Error 1
17:29:38 Build Finished (took 124ms)
Has anyone encountered this before? Or does anyone have any suggestions?
Thanks.
The problem could be described like this:
First, the library should be specified only by its name and without the "lib" prefix and the ".a" suffix. The linker (this is where you get the error) will look for the library within the specified in the project paths and will add whatever is necessary to the file library name. So if the library you need is named mystuff it will look for a file named libmystuff.a.
In your case this is specified by the -l/usr/avr which I think could be misconfiguration or you did not copy/paste the entire error output. With the '-l' option you specify the name only, not the entire path to the file.
Second, the path should be specified, in the project configuration, where to look for the libraries, otherwise the linker will look for the library files only within your own project only. Often libraries are part of another project - so you need to adjust the project configuration accordingly.
I had similar problem and this is how I solved it ...
Go to menu Project/Properties. On left - choose "C/C++ Build". On right - choose the tab "Tool Settings". On the tree view choose "AVR C Linker" then "Libraries" sub-item. You are where you may need to make changes.
The list of "Libraries" is where you add libraries names, such as mystuff.
The Libraries Path is where you specify the paths to the libraries. This may look like this: "${workspace_loc:/mystuff/Release}"
The result of this is that the linker will look for this file: /mystuff/Release/libmystuff.a under you workspace root folder.
I am working on blackberry project when i include
#include <QScriptEngine>
in my .cpp file it gives be error
fatal error: QScriptEngine: No such file or directory
can any one tell what should i include in .pro file so that i can get rid of this error .
Try replacing it with
#include <QtScript/QScriptEngine>
The qt4 include dir should be on your include path by default as long as you have CONFIG += qt somewhere in your pro file. So my guess is you just need to qualify where QScriptEngine is beneath the qt4 dir (which is inside QtScript dir).
I have different behaviour of compiler, when building project from IDE and from command-line, which I can not explain.
The detailed issue's description is rather big, but it's really simple.
I have a C++ Builder project, which has a PAS-file included (IncludeUnits.pas). This pas-file has several units and inc-files listed. These files are located in separate folders and these folders are listed in library&include paths in project's options.
Folders layout:
C:\Demo\Bin
C:\Demo\Project
C:\Demo\Project\CBuilder5
C:\Demo\Project\Common
C:\Demo\Source
C:\Demo\Source\Common
Bin is output folder, Project/CBuilder5 holds project (bpr-file), Project/Common holds included pas-file (IncludeUnits.pas), Source and Source/Common hold other files (pas&inc). I think that it's pretty usual layout.
C:\Demo\Project\Common\ IncludeUnits.pas :
unit IncludeUnits;
interface
uses
Test;
implementation
end.
C:\Demo\Source\ Test.pas :
unit Test;
interface
{$I Test.inc}
implementation
end.
C:\Demo\Source\Common\ Test.inc :
// this file is empty
If I compile this project from C++ Builder IDE - it will compile fine. C++ Builder IDE doesn't have any additional paths in IDE settings set.
Now, I want to compile it from command-line. First, I issue
bpr2mak.exe MyProject.bpr
command.
This command creates MyProject.mak file, where I can see all paths ("....\Source" and "....\Source\Common" are the paths in question):
...
INCLUDEPATH = $(BCB)\include;$(BCB)\include\vcl;..\Common;..\..\Source;..\..\Source\Common
LIBPATH = $(BCB)\lib\obj;$(BCB)\lib;..\Common;..\..\Source;..\..\Source\Common
...
Now, I run make command:
make.exe -B -f"MyProject.mak"
It gives me the following output:
C:\PROGRA~1\Borland\CBUILD~2\BIN\dcc32 -N2....\Bin -N0....\Bin -$Y+ -$W -$R -v -JPHNE -M -UC:\PROGRA~1\Borland\CBUILD~2\bin..\include;C:\PROGRA~1\Borland\CBUILD~2\bin..\include\vcl;..\Common;..\..\Source;..\..\Source\Common -D_DEBUG;_RTLDLL;NO_STRICT -OC:\PROGRA~1\Borland\CBUILD~2\bin..\include;C:\PROGRA~1\Borland\CBUILD~2\bin..\include\vcl;..\Common;..\..\Source;..\..\Source\Common --BCB ..\Common\IncludeUnits.PAS
Borland Delphi Version 13.0 Copyright (c) 1983,99 Inprise Corporation
C:\Demo\Project\Common\IncludeUnits.pas(1) C:\Demo\Project\Common\IncludeUnits.pas(1) C:\Demo\Project\Common\IncludeUnits.pas(1) C:\Demo\Project\Common\IncludeUnits.pas(6) C:\Demo\Source\Test.pas(1) C:\Demo\Source\Test.pas(5) Fatal: File not found: 'Test.inc'
As you can see - all search path is passed to compiler and the file (Test.inc) is all here - in that Source\Common folder. But still compiler can't find it?
Of course, I run both commands from folder with bpr-file. And changing paths to absolute doesn't help.
Copying Test.inc from Source\Common to Source will help. Changing {$I Test.inc} to {$I Common\Test.inc} will also help.
Why? It seems that I'm missing something. Remember: project have no problems with compiling from IDE, Test.inc is found without copying or changing declaration. Did I miss some switch to make or dcc32?
I found the reason: command line for dcc32 misses -I switch, which specifies paths for include files.
For some reason, bpr2mak doesn't respect this option. Fortunately, it allows you to specify alternate template for conversion bpr -> mak. I edited default template and added "-I" option to it, pass new template to bpr2mak - and it worked.
