I just installed Eclipse CPP lunar for my windows 64, and I ran a couple of C code (not c++), but for some reason I can get to the console to show any output, I did the build PATH in the environment part in my properties, but still can't get anything to show. I run my C code in cmd, and everything was perfect! what should I do? do I need to add new flags, it seems the code can run well just no ouput.
update: I watched a video on youtube, and I run some c++ code and the output console is perfect for some reason, just C code I can't get any output. did I built the path wrong?
According to http://www.mochaz.com/2012/03/solution-for-no-console-output-in.html there is a workaround, where you have to add the path of the MinGW compiler (which you most likely use) to the Environment variable of your project (project specific settings).
Goto Project->Properties->Run/Debug Settings, choose the .exe file and press Edit
In the Environment tag, press New, and set it as: Name: PATH, Value: C:\MinGW\bin

I'm trying to run C programs/files from VSCode. I've followed a guide to setting up the gcc for VSCode to use, and it "mostly" works. However, when I run a file, it only outputs to the debug console, which is rather messy. I would prefer if it only output to the "output" window.
If I click on the output window and then try to run the file, I get this error.
This is what my tasks.json file looks like, where I've tried to change build from cppbuild to shell, as well as removing the "file" lines that I saw recommended on other threads, which didn't solve my issue.
Also notice how in the drop down menu for my panel, I don't have a "Code" option that I see in other people's VSCode
TLDR: I want VSCode to display the output of a C file into the Output window, not the debug console. I also want to understand why I am given the "Cannot build and debug because the active file is not a C or C++ source file" error. MinGW has been downloaded and GCC has been set up properly, AFAIK.
Have you installed "Code Runner" extension?
I have Eclipse on Windows 10, I installed MinGW and I'm trying to run a C project.
Path variable is setup correctly. I tried each solution I found online and I ended up in installing Msys as well, setting up its path variable, adding the path variable into eclipse and many other things.
I'm going mad since the two errors don't disappear and I wanted to ask if I can still compile and run my projects or not. I created an hello world sample project and it worked but running my project does not work at all. I can post all the screenshots and code you need but since there's a lot of stuff I will wait for your requests in order to avoid unnecessary information.
Update:
gcc -v command works and shows compiler information.

Found out there was a strange problem within my project that wouldn't let me see the output so I thought there was just a running problem.
Apparently everything works fine, the errors are still there but it seems like they do not interfere with compiling and running processes.
I just downloaded KDevelop from Ubuntu Software Center, and have gcc.
I want to see anything happens by pressing F9 but KDevelop says I need to configure a launcher first. And all I know about the setting window is I have to put 'gcc' in somewhere on the window, as well as path to the source code file and path to the executable file it will make.
I have no any knowledge about this window, no any syntax to use in it and can't find it anywhere on the web. Now I desperately require some help. I want to make KDevelop to compile and debug with already-installed gcc and gdb.
It asks you of which executable to debug. You, i suppose, don't want to debug gcc, so you should set this field to your executable. You can also select Project Target option, and choose CMake target that corresponds to your executable.
This step happens after the build step. Make sure your build process is working first (F8).
The window above lets you select which executable in your project should be run when the launch button is pressed.
If your project is created in KDevelop or otherwise uses CMake as the build system, this should be configured by default and use the "target" part of the dialog.
Otherwise the executable should point to the executable you created as part the build process that you want to test.
Okay here goes, I'm completely new at this, started learning the terminal just about 2 days ago. I'm slowly but surely getting the hang of it, now I'm stuck on this and I've been trying to fix it for a good hour. It's a rather simple question as I am a newby.
I have a C file in my desktop and a Header file in a folder in my desktop. I'm including that header in my C file. I have to link them (currently doing a tutorial, it tells me to link, but doesn't show me how).
You have a couple of options. First, you will need to install the software development environment - it's called Xcode. I think you can get it for free on the AppStore, if not Google it.
Then you need to decide if you want to develop and compile graphically in the Xcode Integrated Development Environment. If you do, start Xcode and create a new project and open your C file and change the "include path" to match the location of your header file. Then click "Build" and "Run"
If you want to do things at the commandline, you'll need to install "Xcode Command Line Tools" - Google it. That will give you a compiler. Then you can compile. I'm not certain which compiler you will get - it could be "llvm" or "gcc" or something else, but the command you are looking for will be something like:
gcc -o prog -I /path/to/HeaderFileFolder yoursourcecode.c
which will give you a program called "prog" that you can run by typing
./prog
You are likely confusing two different concepts. The "link" mentioned in the tutorial is probably talking about turning the compiled objects into a single executable. See http://www.cprogramming.com/compilingandlinking.html for an explanation of what linking means in this context.
What you've provided examples of doing is file system linking, which is totally unrelated.
Providing more details on the tutorial could help refine this answer.
I just installed Dev C++ and I am learning C programming.
the code i used was
#include <stdio.h>
int main()
{
printf("Hello world");
getch();
}
I saved it as a .c file. When I compile it works fine, but when I compile and run it says source file not compiled. So I googled buncha things and came across this video on youtube which shows you how to fix it. I also saw other forums on google which suggest the same thing... However, after doing whats asked, Now I can't even compile my code. I get this error
Compiler: Default compiler
Executing C:\Dev-Cpp\bin\gcc.exe...
C:\Dev-Cpp\bin\gcc.exe "C:\Users\ubaid\Documents\C\Untitled1.c" -o "C:\Users\ubaid\Documents\C\Untitled1.exe" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib"
gcc.exe: Internal error: Aborted (program collect2)
Please submit a full bug report.
See <URL:http://www.mingw.org/bugs.shtml> for instructions.

I have also used what is asked on this link, and still no luck..

I am using windows 8
I was having this issue and fixed it by going to:
C:\Dev-Cpp\libexec\gcc\mingw32\3.4.2
, then deleting collect2.exe
Install new version of Dev c++. It works fine in Windows 8. It also supports 64 bit version.
Download link is http://sourceforge.net/projects/orwelldevcpp/ .
I guess you're using windows 7 with the Orwell Dev CPP
This version of Dev CPP is good for windows 8 only. However on Windows 7 you need the older version of it which is devcpp-4.9.9.2_setup.exe
Download it from the link and use it.
(Don't forget to uninstall any other version already installed on your pc)
Also note that the older version does not work with windows 8.
This maybe because the c compiler is designed to work in linux.I had this problem too and to fix it go to tools and select compiler options.In the box click on programs
Now you will see a tab with gcc and make and the respective path to it.Edit the gcc and make path to use mingw32-c++.exe and mingw32-make.exe respectively.Now it will work.
The reason was that you were using compilers built for linux.
You can always try doing it manually from the command prompt. Navigate to the path of the file and type:
gcc filename.c -o filename
I found a solution. Please follow the following steps:
Right Click the My comp. Icon
Click Advanced Setting.
CLick Environment Variable. On the top part of Environment Variable Click New
Set Variable name as: PATH then
Set Variable Value as: (" the location of g++ .exe" )
For ex. C:\Program Files (x86)\Dev-Cpp\MinGW64\bin
Click OK
This error occurred because your settings are not correct.
For example I receive
cannot open output file Project1.exe: Permission denied
collect2.exe: error: ld returned 1 exit status
mingw32-make.exe: *** [Project1.exe] Error 1
Because I have no permission to write on my exe file.
After some investigation, and with Dr.Topaz's help, I have learned that you will want to confirm that the program set for g++ in the Compiler Options really does compile the source code. In my case, the C:\Dev-Cpp\bin\g++.exe program did not create an exe, but the C:\Dev-Cpp\bin\c++.exe program did. Either program appears to be intended to take the same arguments and options as GNU g++. I would love to find an actual doc on the Dev-C++ compiler programs, but I have not so far.
You can test the compiler program with a simple example like this:
C:\Dev-Cpp\bin\c++.exe hello.cpp -o hello.exe
Currently in 2021, the Dev-C++ site invites you to download either original Dev-C++ or a newer fork by a group named Embarcadero.
I decided to try the Embarcadero version and the experience was slightly better. The UI is still a tad dated, but the g++.exe program it came with was able to compile programs without issue. Again, take note of where the program is being installed, but in my case, the Embarcadero compiler programs were in C:\Program Files (x86)\Embarcadero\Dev-Cpp\TDM-GCC-64\bin.
Both original Dev-C++ and Embarcadero come with mingw-32 versions of the compiler programs that from what I see do work in a Git Bash console, with slight differences such as not recognizing a default locale when using the command std::cout.imbue(std::locale("")).
I faced this similar error, and none of the solutions worked.
so I tried to download the latest version from here, https://www.bloodshed.net/
I rerun the program.
and everything is now working correctly.
I was facing the same issue as described above.
It can be resolved by creating a new project and creating a new file in that project.
Save the file and then try to build and run.
Hope that helps. :)
