I'm using Matlab to generate some C code and MinGW is the compiler. This is how the toolchain is configured:
Once the build process is finished I get an executable file that I can run, and it works fine (it's just a simple Windows console program).
However, I can't find the options to run it automatically right after compilation. I've seen some code where they added ($PRODUCT) to the "Execute" option, but it didn't work for me. Any help is much appreciated!
Following the advice from here:
https://www.reddit.com/r/vim/comments/r6dthv/make_with_makefile_and_run_exe_from_same_command/
I added && start C:\...\test.exe (where ... is the full path) to the "Make Tool" option (bottom line) and it worked.

Let me preface this, I am very new to linux and to working on a non-IDE based setup.
I am trying to debug a very simple C program using vs code version 1.55
I unloaded all modules beforehand, so vs code can load appropriate default gcc & gdb versions (which it did, GCC 8.2)
I am following the VS code getting started documentation for setting up and everything seems very straight forward until I try to debug.
I use the default settings as instructed, the file builds successfully but then I get the below
/usr/bin/gdb: symbol lookup error: /usr/bin/gdb: undefined symbol: PyUnicodeUCS4_FromEncodedObject
please note that I cannot rebuild python with ucs4 enabled as suggested in another thread as I have no root access. however I can change VS code version to an earlier one if this will help.
Thanks.
I think this issue is specific to my environment but I will post the answer anyway as it may face someone else.
So this for me was 2 separate issues:
First gdb doesn't start and second vs code can't start gdb.
To check if this is the case try to launch gdb from terminal (not vs code) by typing gdb in the terminal (after loading gdb if needed), I was receiving the error above
Solution to this part is this as T0maas thankfully suggested above
Steps for linux newbies:
ldd gdb (or /usr/bin/gdb) (with vs_code loaded)
from step one get the python library path
unload all modules
load gdb
LD_PRELOAD=<python path from 1>
bash -c "export LD_PRELOAD"
load vs_code
load gdb
After the above steps writing gdb in the terminal should start gdb
Part 2:
The rest of the problem was when I tried to launch debugging session through the GUI of vs_code (still produced the same error)
In the terminal (after loading gdb) type whereis gdb
For me this produced multiple directories the first of which was /usr/bin/gdb (this is the default used in vs_code launch.json)
Changing that directory in the launch.json file to a different one of the other directories solved the second part of the problem for me.
I am using Codeblocks in Windows 10. Earlier I used to compile only 1 file, so I would just press the 'Build' and 'Run' button on codeblocks.
But, this time there are separate files I need to compile separately (to .o format) and then link to form a single executable file which I need to run. How can I do this in CODEBLOCKS? (In UNIX/LINUX systems, I know this is the 'make' command; but I don't know how to do it here?)
Can anyone help me? I tried reading some help pages on CodeBlocks on the internet, but they were so complicated, I gave up.
make isn't a compiler, and neither is CodeBlocks. make is just a command that runs other commands from a Makefile. The actual command that gets run is something along the lines of gcc a.cpp b.cpp, and it's the same command (or similar enough) that gets run when you build inside CodeBlocks. CodeBlocks should automatically build and link all of the source files that you add to your project. If you aren't seeing this happening, make sure you add them to the project inside of CodeBlocks and don't just put the files in the directory.
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.
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.
Execution terminated
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. :)
C.Vim works, as evidenced by the commands I've been using, syntax highlighting, and template. But I use \rc and nothing happens. \rr tells me that there is no .exe, and an Everything search tells me that it's not a directory issue.
In all the resources I've read, I don't see anything that says I need to point it to a specific compiler, though I've installed Visual Studio 2010.
How do I get C.vim to compile my code? I'm a relative beginner with Vim and C.
Edit: I've set the Windows Environment Variable to C:/cygwin/bin where I've downloaded and installed the GCC packages, but am still getting the same error.
Edit2: I've downloaded Msys and Mingw as well. I tried setting up Eclipse as well, following the instructions here. Running make from the command line tells me that GNU Make 3.81 is running. Running :make in Vim tells me:
shell returned 2
(1 of 1) : make *** No targets specified and no makefile found
Trying Eclipse, I get another make error:
make: *** No rule to make target `all'; Stop.
Edit3: I got Code::Blocks running, which is what I used to run. (It's been a while since I programmed, and even then I was a beginner.) I didn't really have to configure it at all, though I would still prefer to use Vim, so help is still much appreciated.
Edit4: running make vimFirst (vimFirst.c is my file) compiles! Running the program with :! vimFirst.exe works as expected. Now returning to the original question, how to do it with C.vim? It would be so much more convinient to type \rc and have the program compile and run, which is about 1/10 of the typing of the other method.
Edit4: running make vimFirst (vimFirst.c is my file) compiles! Running the program with :! vimFirst.exe works as expected. Now returning to the original question, ... type \rc and have the program compile and run...
Check your maps for \rc and \rr:
:map \rc
:map \rr
If no mapping exists, you might have no_plugin_maps or something similar set in your vimrc.
I think you'll get what you want if you set them up like this:
nmap \rc :make %<<CR>
nmap \rr :! %<.exe<CR>
If you're really familiar with Visual Studio and want to use nmake to build your code, you should check out the :compiler option. :compiler msvc will setup your makeprg and errorformat for nmake and Visual Studio's compiler.
I'm not sure what make is currently using to build your code, so I don't know what compiler setting you'd want.
