Maybe simple...

sudo apt-get install gcc

... could be enough?

Your line

Copygcc‬‬ ‫‪-g‬‬ ‫‪-m32‬‬ ‫‪-o‬‬ ‫‪skip‬‬ ‫‪skip.c

is ASCII broken. There are strange (invisible) characters before the spaces. Check it here.

Also, to run gcc with -m32 flag on, you need to install gcc-multilib first:

Copyapt-get install gcc-multilib

Sorry I can't comment yet.

But I must point out that the original ln command is incorrect, which creates an incorrect relative link usr/bin/gcc-4.8 under /usr/bin/

Correct command is

sudo ln -s /usr/bin/gcc-4.8 /usr/bin/gcc

or

sudo ln -s gcc-4.8 /usr/bin/gcc

If sudo apt-get update does not work for you, you should maybe try sudo apt-get clean to clean the cache and then execute sudo apt-get update

You need to update your system:

sudo apt update
sudo apt upgrade
sudo apt install gcc

gcc is in /Developer/usr/bin and /usr/bin. Check these directories and the value of your PATH environment variable, and add to it as needed.

You are not configuring the correct config file. Check this out:

https://wiki.archlinux.org/index.php/Zsh#Configuring_.24PATH

Check that gcc is installed correctly:

brew install gcc
brew link gcc48

Create an alias to whatever link brew created and put it in your .zshrc

cd /usr/local/bin
ls cpp*
ls c++*

alias gcc=/usr/local/bin/<whatever_link_you_found>

You'll have to completely purge what you have and perform a fresh install.

Much of this is done automatically when using the GUI. But when using the commandline you have to be specific to remove the leftover packages and other files manually.

First completely purge/remove what you currently have installed, which isn't working. Clean and update your repository cache and packages, then freshly install gcc.

$ sudo apt purge gcc
$ sudo apt-get autoremove
$ sudo apt update
$ sudo apt upgrade
$ sudo apt full-upgrade
$ sudo apt install gcc

Check for errors between commands. There shouldn't be errors. If they are, address the suggested remedy provided to fix the error. For instance, there might be an occasional warning or error such as:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

To resolve that particular state, run:

$ sudo dpkg --configure -a

Then after fixing that part, proceed to the next step.

Each of the commands should give a clean state. You'll then have a fresh install from the repository.

In short: When cross-compiling Linux kernel, you need not only a cross-compiler, but a compiler (gcc) for your host too.

When build the Linux kernel and modules, the build system not only compiles binaries for the target platform, but also executes some programs on these binaries. These programs are shipped with the Linux kernel sources as sources, so for build these programs host compiler is needed.

By the way, a line started with HOSTCC means that exactly host compiler is used for that operation.

I took an update today on my Ubuntu 22.04 and encountered the error with VMware Workstation 16 Pro 16.2.4 build-20089737 shown in the question here.

GNU C Compiler (gcc) version 12.3.0, was not found. If you installed it in a non-default path you can specify the path below. Otherwise refer to your distribution's documentation for installation instructors and click Refresh to search again in default locations.

I've used VMWare every day since this OS was fresh installed in 2022.

There were three problems to fix:

Missing gcc 12

My gcc --version is 11.4.0. I checked ls /usr/bin/x86_64-linux-gnu-* and version 12 was not there.

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/ppa -y
$ sudo apt update
$ sudo apt install g++-12 gcc-12

Then try again.

skb_gso_segment undefined

The build breaks because of gcc header changes. The VMWare build provides a log file like /tmp/vmware-user/vmware_1234.log that shows the compiler error.

This particular function, skb_gso_segment, has moved to a new header that VMWare bridge.c does not #include.

To see for yourself the header where this function is defined, cd /usr/src/linux-hwe-6.5-headers-6.5.0-14/include/net and grep skb_gso_segment *.

To fix VMWare code:

$ sudo su
$ cd /usr/lib/vmware/modules/source

# back up original tar file
$ cp vmnet.tar vmnet.tar.original

# change the code
$ tar -xvf vmnet.tar
$ nano vmnet-only/bridge.c

After the #include <linux/netdevice.h>, add

   #include <net/gso.h>

Save and exit. Then rebuild the tar file.

$ tar -cf vmnet.tar vmnet-only
$ exit

Then try again.

__pte_offset_map undefined

Next the build fails because a function has changed names. In VMWare Workstation 17, the code in pgtbl.h was changed like this by VMWare:

#if LINUX_VERSION_CODE >= KERNEL_VERSION(6,5,0)
            pte_t *pte = pte_offset_kernel(pmd, addr);
#else
            pte_t *pte = pte_offset_map(pmd, addr);
#endif

To fix v16, I made a similar change.

$ sudo su
$ cd /usr/lib/vmware/modules/source

# back up original tar file
$ cp vmmon.tar vmmon.tar.original

# change the code
$ tar -xvf vmmon.tar
$ nano vmmon-only/include/pgtbl.h

In the editor, search down to pte_offset_map and change it to pte_offset_kernel.

Save and exit. Then rebuild the tar file.

$ tar -cf vmmon.tar vmmon-only
$ exit

Then try again.

This got me back in operation.

gcc isn't installed anymore by Xcode, it really installs clang and calls it gcc

usxxplayegm1:~ grady$ which gcc
/usr/bin/gcc

usxxplayegm1:~ grady$ /usr/bin/gcc --version

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.0.2
Thread model: posix

you need man clang

I thought it was a symlink, but ls -l doesn't list it as a symlink, so either it is a hard link or some other sort of trickery.
