So I tried to check Mingw-w64 tools are correctly installed and gcc, g++ were correctly installed but gdb wasn't. I'm planning to usE Visual studio code in windows 10.
In the https://code.visualstudio.com/docs/cpp/config-mingw#_run-helloworldcpp, it said to match PATH entry but when I went to C:\msys64\mingw64\bin directory, the file was empty. Did I miss something or how do I know the correct path to put in the environment variable?
I tried C:\msys64\mingw64\bin as both user variable & system variable path but it won't work. and it said command not found.
This is what it said.
$ gdb --version
bash: gdb: command not found
Try installing GDB by running this in your Bash shell:
pacman -S $MINGW_PACKAGE_PREFIX-gdb
I have a C++ project imported to Eclipse CDT. I can build and run the project using Makefile and argument settings. However, when I tried to add a debug point and run "debug as local c/c++ application", it throws me an error of "Launching projectName" has encountered a problem. Error with command gdb --version
By expanding the Details, it gives: Error with command: gdb --version
Cannot run program "gdb": Unknown reason
I installed the gdb by Macports before. If I enter command ggdb it returns the version info. If I type which ggdb, it gives /opt/local/bin/ggdb. I tried to add "PATH" to debug configuration -> environment variables and give the path value to it, but it did not work. How should I set the path and link the path please? And what should the variable name be.
The gdb version on my machine is GNU gdb (GDB) 7.7.1
Added: I looked up which ggdb and used the link James provided to change gdb debugger to browse to that path. But it did not work still.
Thanks.
It looks like Eclipse is using the default gdb that was on the system before you installed ggdb from macports. This link shows how to change the debugger settings, change it to ggdb which is the name Macport uses.
After installing ggdb from Macports you will have to sign it with a certificate so it will be allowed to control other processes, take a look at "Certifying GDB" here. After creating the certificate, make sure you select the correct name when signing:
$ codesign -s gdb-cert $(which ggdb) /// 'ggdb'
I am getting this error when i tried to compile my program
-bash: g++: command not found
Also I have only been getting this error after I formatted my Mac Book Pro
This error came after I did this
g++ functions.cpp
Please help me.
Thank You
Here is a cleanest solution than installing XCode just for Gcc.
STEP 1 > install this:
[HomeBrew Web Site] (http://brew.sh/)
All the informations concerning the installation and the utility of such a program are on the site itself.
It's a package manager, but for Mac. It's like apt-get or yaourt, if you ever used Ubuntu or Arch Linux.
STEP 2 > Go to the Terminal application and type :
$> homebrew search gcc
Then choose from the version you want, and type again in Terminal:
$> homebrew install [choosen version]
Gcc is now installed.
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:
