I have Code Blocks 12.11 and I have Cygwin 1.7.27 installed. I have configured C::B to run the Cygwin compiler and it works, but when I try to run the debugger from the Code Blocks environment I get the error:
Cannot open file /cygdrive/c/some_path/main.c
At /cygdrive/c/some_path/main.c:15
If I try to run gdb on the same file from the cygwin command line interface, it works.
Can somebody please help me fix this problem?
A way to make it work is adding a string value under
HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin\mounts v2
HKEY_LOCAL_MACHINE\Software\Cygnus Solutions\Cygwin\mounts v2
with
name = cygdrive prefix
value = /cygdrive
If the folders do not exist you have to create them manually.
I have the same problem and this fix does not work if Cygwin is installed separately and then Code::Blocks is installed later.
I am using Code::Blocks version 13.12 and GDB version 7.6.5.

I installed mingw and checked it in cmd by writing c++ --version it runs sucessful but whenever i open my codelite it says could not locate any mingw on your machine i have tried reinstalling both mingw and codelite few times nothing works someone please help me
Tried scanning mingw compiler on codelite but it could not locate mingw and it(mingw) is already installed in my machine and running too help me please
I don't know much about this IDE but this link is probably what you are looking for.
https://wiki.codelite.org/pmwiki.php/Main/AddNewCompiler
Since the scan failed you will have to manually add the path to your compiler in codelite. The compiler will most likely be in the mingw folder under the name 'g++.exe'.
I am using c++/eclipse kepler on mac, and I cannot debug any project. The error is "Error while launching command: gdb --version" Besides that, I can build and run my code using other libraries.
I searched a site that is similar to my problem: Debugger for C++ eclipse gives the following error. 'Launching program name' has encountered a ... Error while launching command: gdb --version
But what should I change if I am using a mac?
You can fix this by specifying the full path to gdb. You can do this separately for each debug configuration, and you can also set the default gdb location in the preferences under C/C++ > GDB. For example, if you installed gdb via Homebrew, then it's probably located under /usr/local/bin:
And here's a screenshot of the Preferences:
I still don't know why Eclipse can't find GDB even though it is on my path. I guess it doesn't use my .bash_profile or my .bashrc? You could try symlinking gdb into /usr/bin. Maybe Eclipse will look there.
Edit: I tried the symbolic link idea and now Eclipse can debug, but it crashes inexplicably while doing so! So, I guess... don't do that?
This guide from a UC Irvine Computer Science professor's page is a very well-written, detailed, and Mac-specfic description of all the steps involved in installing GDB, creating a certificate, signing GDB using that certificate, and finally configuring Eclipse. I was found this very helpful as someone unfamiliar with each of these steps.
GDB Installation on Mac OS X
I had the same problem. I solved it by:
Install a gdb - ( I used 7.8.1) - compile and install it. It got installed in usr/local/bin
Codesigning certificate
Open eclipse executable using sudo. Otherwise I still get the error.
I am on OS X.
Hope this helps.
I had this error too now, and spent more than an hour looking for it.
In my case, the path was correct, and eclipse seemed to fail to start "any" executable as debugger. (I tested with gksudo cat, but it clearly never got to effectively running it).
The final reason was that I had put in my eclipse.ini -Xms1G and -Xmx1G. It seemed to already use the full memory for the indexer, and trying to allocate some more memory to start the debugger failed with an "unkown" error. Removing the memory limitations fixed the issue.
Hope this helps someone
I had many difficulties making GDB to work on Eclipse. I tried LLDB instead and it worked like a charm:
https://wiki.eclipse.org/CDT/User/FAQ#How_do_I_get_the_LLDB_debugger.3F
This can be a more convenient alternative for Mac users.
Mac OS Sierra 10.13.6 gdb 8.0.1
had the same error as topic-starter.
first, I set the path as Neil Traft (here in the answers) explains to usr/local/bin/gdb;
But it didn't work.
I found these instructions:
https://gist.github.com/gravitylow/fb595186ce6068537a6e9da6d8b5b96d
and I discovered that I already had gdbcert1 in my System. So I followed everything from 7. Works!
I've always worked around the debugger issue, but now it has gotten too annoying. I'm working on more complex programs and can't anywhere if I cant debug my programs. Has any one else been able to fix this issue in eclipse? It works for java, but not more my C++ plugin from minGW
Debbugger for C++ eclipse gives the following error. 'Launching program name' has encountered a problem. Error while launching command: gdb --version
Assuming you are using Windows and have MinGW installed, you only need to locate the gdb executable in the MinGW bin folder. This can be done on the "Main" tab in the "Debugger" configuration of Eclipse:
I am currently trying to set my eclipse so that I can start c++ development on my Windows computer. However, I am stuck with some errors. But first, here is what I did so far:
Installed the CDT for Eclipse
Installed Cygwin (with the additional packages gcc, gcc and make)
Added all "paths for headers" in Eclipse
The problem is that when I try to run my Hello World program, I get Launch failed. Binary not found.
I already build and rebuild the project but the program is still not running. It must be because of these errors that I have:
/bin/sh: g++: command not found
make: ***[src/HelloWorld.o] Error 127
What can I do to solve these errors?
Try running the Cygwin setup.exe again and select the packages for g++. Search for that and make sure those are installed. It should be under the name gcc-g++. The C++ compiler is installed separately from the C compiler.
Ok, I figured it out by myself. Since this really freaked me out, I want anyone else who has this problem to know how I solved it.
So apparently, since I had g++, gcc and all that installed, it had to be a problem with the path.
So what I did was check my path. If you don't know how to edit it, check this link http://www.computerhope.com/issues/ch000549.htm
So in there, I chose Path under the System variables and clicked on Edit.... What I noticed was that instead of C:\cygwin64 it said C:\cygwin. All I did was append the 64 (since I had installed the 64-bit version of cygwin) and I was done.
I restarted Eclipse, cleaned and built the project and the errors where gone!
I am trying to use Eclipse CDT with Cygwin, but I have problems with the debugger. I have done the following:
- installed Eclipse CDT
- installed Cygwin with gcc, g++ make and gdb
- added c:\cygwin\bin to PATH
- created a new Hello World application in Eclipse
Compiling went well from Eclipse. The first problem was that I had to set the executable manually in the run configuration. Having done this, I running also worked. But when I try to debug, I get the following error:
When I switch to debug perspective, I can see the following:
I tried different debug configurations, but I always get the same result.
First, make sure gdb is located on c:\cygwin\bin. I believe executing which gdb on cygwin might help you do that.
Now, instead of adding this information to PATH and making it available to all your Windows applications, try adding it to your project settings inside Eclipse, like this guy did:
