Just as the title says - I'm trying to get the newest gcc on my Mac (Yosemite) using Macports. I tested other commands to make sure Macports is working - ex. "port search gcc" works for me.
so, I go to type "sudo port install gcc5" - nothing happens. I try "sudo port install gcc_select" (after seeing this suggested on an answer to a different question on this site) - nothing happens. If I use "top" I see that xcode is very busy doing SOMETHING related to what I have typed, but I let my computer sit ~ 10 minutes and there is no text or anything telling me that Macports is actually doing something...
Help please! I'm a previous Windows user and all of this is very much over my head. I have no idea what could possibly be wrong and I haven't seen this asked anywhere.

Today I wanted to compile some C-Code when VsCode gave me an include-path error. I thought that was odd, since I didn't remember changing anything there. So I tried to compile my code with C-Lion, but right after opening C-Lion, there was another error-message telling me, that it wasn't able to compile a small test-programm and gave me a usr/bin/cc - broken error message.
After trying to figure out where the problem was I remebered that I was cleaning up my Mac the other day and deleted folders that I thought would belong to the RiotClient, that I just uninstalled. My guess is that I deleted some folders that I shouldn't have deleted ...
And of course I already emptied my trash bin.
As I am using clang to compile (Vs-Code) I tried to check for my clang version (using clang --version in the terminal), which again ended in a usr/bin - error message (xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun)
Is there any way to get out of this mess or do I need to reset my mac completely.
Thanks for any help in advance!
Solved!
As #JonathanLeffler suggested, the solution is to reinstall the XCode Command Line Tools. It seems like the latest MacOS update mixed something up, which seems to be a common thing to happen (see comments).
I followed this guide to reinstall it :)
It doesn't seem to be necessary to download the XCode IDE as I thought haha.
I followed the tutorial here from the Medium: https://medium.com/#GuruAtWork/setup-fastai-ubuntu-on-windows-10-44ca50b13a9
I was following it well until a MinGW was used for command lines. I am not sure how they went about doing this as the only way I could get nvcc to work is with sudo apt install nvidia-cuda-toolkit. However, this does not seem to complete the same thing as their tool kit is installed as if the exe was just run with Windows. However, that, of course, doesn't work with the Ubuntu. Let me know what you think, thank you.
AFAIK it's just not possible right now to do so from WSL. The link from Medium only sets it up for the Git bash prompt, which is not the same as WSL.
I am a beginner C programmer, and recently I have run into a problem that I was unable to solve.
I am struggling to install and use a C library. The message error is:
My OS is Mac OS X and im try install the file with ".command" format.
Can someone help me install this library?
Thanks in advance.
More than help installing the library, you need help in understanding what's going on.
Someone gave you a command to run and you ran it, but they were assuming that you were using a different OS, like Ubuntu.
The first message "apt-get not found" is because you're running MacOS, which doesn't have an "apt-get" command.
The second error is because you also don't have wget.
The rest of the messages indicate a poorly written script file, since it blew up twice and still went on to truncate files and do other things.
While you're not going to be able to install apt-get, you might be able to find a compatible version of wget. If not, you can download whatever it was trying to get using your browser, since wget is typically used to automate web HTTP/HTTPS requests.
Without seeing the file, I don't know what the rest if the script was trying to do, but if you read it you should be able to figure out what it was doing, and do it manually.
An easier way to do all this is to install Virtualbox on your mac and run a copy of Ubuntu inside a virtual machine. Then you can run your class assignments without needing to rewrite them all.
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 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.
