When I try to open Code::Blocks this message appears "Can't find compiler executable in your configuration search path's for GNU GCC compiler".
and I can't run any projects.
Install MinGW if you haven't(it should come installed with Code::Blocks). Then run Code::Blocks go to Settings->Compiler Setting->Toolchain executables and press Auto-Detect .If auto detect doesn't work include the path yourself(find where you installed MinGW).Also make sure that in Project-> Build options you have selected the GNU GCC Compiler

I am using Codeblocks and have to run an OpenMP C program. So, I added the flag -fopenmp in Codeblocks (compiler settings) and am now getting the error of 'mingw32-g++.exe: error: libgomp.spec: No such file or directory'
So after a bit of searching on the internet about the error, I downloaded TDM-GCC ( installed in C:\TDM-GCC-64). But still the same error is being shown on Codeblocks.
What am I doing wrong?
Here is the build log:
mingw32-gcc.exe -c "D:\Language Files\MatrixMultiplication.c" -o "D:\Language Files\MatrixMultiplication.o"
mingw32-g++.exe -o "D:\Language Files\MatrixMultiplication.exe" "D:\Language Files\MatrixMultiplication.o" -fopenmp
mingw32-g++.exe: error: libgomp.spec: No such file or directory
There are multiple possible causes for this: Either you did not install OpenMP with the compiler or you made a mistake in the Code::Blocks configuration. Anyways go through the following steps and you should be able to fix it. You seem to be working on Windows but I also added remarks on how to do it on Linux.
1) You will need a compiler that comes with OpenMP. For Windows download TDM-GCC preferably the 64-bit executable (second file) and install it. Make sure you select OpenMP in the component tab: Components > gcc (TDM current: ....) > OpenMP (the last entry). Linux already comes with GCC so just open the command line and get yourself OpenMP by typing sudo apt-get install libomp-dev in the terminal.
2) You will have to configure the Compiler in Code::Blocks now: Go to Settings > Compiler under Selected Compiler select GNU GCC Compiler and click Copy and type in a convenient name for your new compiler such as TDM-GCC Compiler. Go to Toolchain executables and browse the directory for all the Program files (C compiler, C++ compiler, Linkers, Debugger, Resource compiler, Make) you should be able to find them in C:\TDM-GCC-64\ ...\bin on a Windows machine if you chose the default installation. I can't tell you the precise sub-directory as I working on a Linux machine but you should be able to find it pretty easily. Depending on your installation there might be two folders for 32- and 64-bit. For Linux this step is not necessary.
4) Then you need to set the Linker settings. This can be done for all projects (which I would not recommend) by doing the following steps in the aforementioned menu or for your current project by clicking Project > Build options. Go to Linker settings of the corresponding configuration (Debug or Release) and click Add under Link libraries. On a Windows machine you will need to browse a file called libgomp-1.dll (32-bit) or libgomp_64-1.dll (64-bit) which should be located in the same folder as the aforementioned Program files. Under Linux instead choose -lgomp under Other linker options.
3) Set the compiler flag -fopenmp (for all the projects or only the current one) by going to Compiler settings > Other compiler options and typing in there -fopenmp.
4) Test it with a program like the OpenMP "Hello World".
I downloaded atom a couple of days ago and I can't seem to find the right package or where and how you compile the program.
does anyone know?
Now, it's possible to run and compile (also debug) C and C++ program from within atom editor.
Install gpp compiler package in atom editor.
Prerequisites:
Windows:
You'll need to install MinGW and add it to your system PATH.
Mac:
You'll need to install XCode.
Linux:
The GNU Compiler Collection may come with your distribution. Run which gcc g++ to find out.
To compile and run: F5
To debug: F6
Atom is "simply" a Text editor that is not able to compile anything. If you use a Makefile, then there are a few add-ons for building targets via key bindings.
If not, open a terminal and use the C compiler on your system. On Linux/Unix machines you probably want to use gcc:
gcc <your_source>.c -o <output_name>
EDIT
Or take a look at This Package
here's a link for atom gnu gcc compiler-- https://atom.io/packages/gpp-compiler
1. download it
2. place the file in atom's package folder
3. press F5 on atom editor to RUN n Compile your file.
it will open text.ext as a output.
Can you tell me how to install GTK on windows 10 or have a step by step guide, all the ones I've tried have not helped me.
Possibly if someone also explain how to compile from cmd or prepare an IDE (code: block maybe).
Any commands I mention should be run at the MINGW shell, found here: C:\msys64\msys2_shell.cmd
First update msys2 with pacman -Syu
Make sure you have installed GCC...Install the required toolchain for GCC with pacman -S mingw-w64-x86_64-toolchain. When using pacman, just keep typing enter if prompted to follow through with the installation and get back to the command prompt.
In order to set this step up with Code:Blocks, make sure you go to the Code:Blocks menu Settings->Compiler, and the menu Toolchain Executables. From there, put in the msys2 installation directory and where you installed MinGW's GCC compiler (for me this was putting C:\msys64\mingw64) under the compiler's installation directory option. Also edit the C Compiler path under the same menu to x86_64-w64-mingw32-gcc.exe.
Next, in order to install gtk+3.0, use the command pacman -S mingw-w64-x86_64-gtk3. Now the latest version of GTK+3.0 will have been installed, so it is time to set it up with Code:Blocks.
Open Code:Blocks and create a new C file. You may definitely write your code in Code:Blocks, but I do not suggest that you compile it from there. Two compile, go back to the MINGW shell. Type nano ~/.bashrc to edit it. You may scroll down using the arrow keys to the bottom of the file and add: PATH=$PATH:/c/msys64/mingw64/bin. Restart the MINGW shell and open it back up.
Finally, try running:
gcc source.c -o executable.exe `pkg-config --cflags --libs gtk+-3.0`.
If that command doesn't work, I would suggest using the i686 version of gcc installed in MINGW.
I hope this helps!
I have installed codeblocks in windows 7 first time and try to run a simple C program but I get this error?
can't find compiler executable in your search path (GNU GCC compiler)
I tried many things to solve it but unable to compile.
Have you installed the Mingw compiler or any other simiar compiler? If not install that first. After you have done so, you need to set codeblocks to use that compiler. You can do that by going to the settings>compiler settings and set the necessary options there. You may need to refer the place where you have installed Mingw or other compiler. Note the compiler executable is gcc for C and g++ for C++ and the linker is ld i guess. Debugger is gdb. You need to tell codeblocks where are these located.
I also received that error. I fixed it using Settings -> Compiler -> Global compiler settings -> Toolchain executables -> Auto detect.
I can't get Code Blocks IDE to compile the hello world C program it creates when you create a new C project. I've installed MinGW and it was recognised by the IDE. But when I try to build I get the following output:
-------------- Build: Debug in TestC3 (compiler: GNU GCC Compiler)---------------
mingw32-gcc.exe -Wall -g -c
C:\Users\jody\codeblocks\testc3\TestC3\main.c -o obj\Debug\main.o
mingw32-g++.exe -o bin\Debug\TestC3.exe obj\Debug\main.o Execution
of 'mingw32-g++.exe -o bin\Debug\TestC3.exe obj\Debug\main.o' in
'C:\Users\jody\codeblocks\testc3\TestC3' failed.
Why is it trying to run mingw32-g++.exe as well as mingw32-gcc.exe? (And if it shouldn't be doing this, how can I configure it not to?)
The mingw32-gcc.exe step is the compile step. The mingw32-g++.exe is the link step. This
is the correct sequence and will work if your mingw32 installation is "normal" and correct - where "normal" means
you have installed the C++ as well as the C tools.
The link step is failing for you because mingw32-g++.exe cannot be executed, most likely because
it does not exist on your PATH. Try running mingw32-g++.exe at the command prompt to check.
Look in the directory where mingw32-gcc.exe resides to see if mingw32-g++.exe is also there.
If your mingw32 installation has got broken somehow I suggest you uninstall and reinstall.
If you have intentionally installed only the C tools then that will explain what you are
seeing, and it is easily fixed:
Both mingw32-gcc.exe and mingw32-g++.exe are just tool driver programs. When invoked
with compilation options for .c files, mingw32-gcc.exe invokes the C compiler. When invoked
with compilation options for .cpp|cxx|... files, mingw32-g++.exe invokes the C++ compiler. If
either of them is invoked with linkage options then it invokes the linker.
Codeblocks by default configures mingw32-g++.exe to invoke the linker because it will do equally
well for C projects, C++ projects and C/C++ projects, and it assumes you have the full C/C++ toolchain.
If you have not installed C++ tools and only want to build C, then you can use mingw32-gcc.exe
to invoke both the C compiler and the linker. To configure this in the CodeBlocks IDE:
Navigate Settings -> Compiler
Ensure that the Selected Compiler is GNU GCC
Tab to Toolchain executables
Change Linker for dynamic libs from mingw32-g++.exe to mingw32-gcc.exe
OK out of Settings and rebuild your project.
Firstly uninstall the codeblocks if you can't get something right. Move to codeblocks official site to download its minw.exe version so that you have a proper compiler for all of your C programs.
After installing go to Setting>Compiler>GNU GCC compiler.
Move to Toolchain Executables>.
Now set Compilers Installation Directory. Most probably it's C:\Program Files\CodeBlocks\MinGW\bin. Now you have to select and locate your C compiler as it is in the above mentioned directory.
After that rebulid and run your program.
It may occur because compiler installation directory path is wrong.to fix it
settings -> compiler -> toolchain executables. now set compiler directory to compiler folder. it must be in CodeBlocks folder if you downloaded CodeBlocks compiler integrated version(ex: C:\Program Files\CodeBlocks\MinGW). else you need browse to location where compiler is installed
if you can't find compiler then uninstall codeblocks and download again . but this time make sure you downloaded one which has "mingw" in name for windows.
