I should preface this by stating I'm working with Xcode on macOS Sierra 10.12.6.
I installed GDB with homebrew and it appeared to install fine until I tried to use it. In terminal it kept saying that it was not a valid command. (I'm new to C and was working with my professor. Even he was baffled when I tried to use it after downloading it in front of him). So later I tried to install it by creating the make file and still having problems. I then used homebrew again but to uninstall and reinstall, still having problems.
Now I'm at the point where I can't even run my C files when I use gcc to compile them. I simply get a statement that unable to open file. I've read someone suggest to sudo mv /usr/local /usr/_local and I'm notified that I don't have permission, even after entering in my password.
I've gotten every error when I try to remove all items belonging to gdb. I've gone as far as removing Xcode in hopes that I can do a fresh install of it all.
I'm at the point where I've begun looking into removing my macports entirely.
I'm looking for any advice into how I can try to start off from a clean slate. I need to use gdb on a project that is due and can't get this up and running. Please help talk me from a ledge!
EDIT:
I have used Sublime to create a simple Hello World file and it compiles and runs fine with gcc. So my project file has become corrupted somehow. At least I can calm down a bit. But I would still like to get this gdb issue figured out and install a fresh copy with everything old removed.

I don't know how to reinstall gdb on macOS, but be aware that gdb is broken on macOS Sierra as of now (at least debugging dynamic libraries), see Bug report.
So if you even get gdb correctly installed you can probably end up with nothing (gdb won't be able to debug what you want).
Try making your file executable using gcc -Wall -g $fileName.c -o $fileName. This will show all the errors that might exists. Secondly, if it doesn't work and you absolutely need to use gdb, using a VM of Linux(recommend Ubuntu if you're new to Linux or Mate) is a good alternative. You then have to just use sudo apt-get install gdb and even install gdb-dashboard git-hub gdb-dashboard if you want to do some serious debugging. That's the quickest fix that I can think of you are in a hurry. Btw good VMs are VirtualBox and Parallel Desktop(if you want to have access to your local files from the VM).
I've installed Clion and MinGW, however in setting for Clion I get a message saying that C Compiler is not found. As shown here:
Although I believe I've installed all variations of the gcc package as shown:
It also appears I'm missing gcc.exe:
Anyone know what I'm missing and how to correct this error?
I found the solution. It appears that it wasn't actually downloading and extracting the exe properly.
To fix it I clicked on the general tab for the package I wanted in the package manager, then had to type the Package URL into my browser (can't copy it for some reason). That downloaded the folders, so I just extracted them and put them into their respective directories and Clion now detects the compiler!
The link for my version was https://sourceforge.net/projects/mingw/files/MinGW/Base/gcc/Version4/gcc-4.9.3-1/gcc-core-4.9.3-1-mingw32-bin.tar.xz/download?use_mirror=iweb
I upgraded to Yosemite, and now all my compilers (from the command line—gcc and icc) are giving me errors like: cannot open source file “ctype.h"
Does anyone know how to fix this? Do I need to reinstall the compilers?
OK, not sure what’s going on here, but after updating to Xcode 6.1.1 and installing the associated command line tools, icc seems like it can now find the system headers. Now having a separate issue with gcc, will post separately…
I've been installing "hamlib 1.2.15.3" (sourceforge) on my RaspberryPi under Raspbian and everything
worked great for a while.
When I noticed an unimplemented feature, I downloaded the newest developer version here:
here (something like this, but this link may change every day: http://n0nb.users.sourceforge.net/hamlib-3.0~git-6e44327-20140321.tar.gz)
So I downloaded it and did the usual: untar to a folder, ./configure, make, make install.
After all was done, I launched rotctl and there comes this message: rotctl: symbol lookup error: /usr/local/lib/libhamlib.so.2: undefined symbol: g313_caps
I thought the package wasn't flawless and I tried to install the old version again. But it's still like that. Also I tried ldconfig every now and then.
To be honest: I'm a beginner when it comes to linux, so I don't know what I have done there. Maybe I was doing a major mistake, a normal linux user wouldn't do. Maybe it was wrong to install that package without uninstalling the older version. Also I don't even know how to do that.
Basically there is only one file in the source code, I need to change to the newer version. So, if there is anyone who could tell me, how to make a clean uninstall, I could replace only this file in the source and install again. I think that would do the thing.
Or shall I rather ask the people from the hamlib developer team?
Thank you in advance.
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. :)
