Solve Configure: Error: No Acceptable C Compiler Found in $PATH

When you install a package or application, there are several dependencies that such a package runs on. These dependencies power some (or all) parts of the package.

Often, some of these dependencies are bundled together or downloaded during installation. Other times, it is expected to be present within your system.

For Linux, a big example is when installing Python. The C compiler is an important dependency that it needs.

Well, that’s because Python is written in C. However, we might not have the C compiler present, and it is expected by the Python developers to be present on your Linux PC.

This article will show you how to solve the error message configure: error: no acceptable C compiler found in $PATH when installing Python or any package that needs the C compiler.

Install gcc to Solve configure: error: no acceptable C compiler found in $PATH

The GNU Compiler Collection (GCC) is a compiler that holds compilers for different programming languages from C and C++ to Go. In addition to these compilers, it holds important libraries run on the programming languages it supports.

From the description, we know it holds the C compiler that is not found in our $PATH. Therefore, if you see this error message configure: error: no acceptable C compiler found in $PATH, the gcc compiler can help you solve it.

Let’s create the same error message scenario by installing Python on our Ubuntu PC. To install Python, we need to download the tgz file, a compressed archive file using the GNU zip (gzip) software holding the Python package.

To download the Python tgz file, we can use the wget command.

wget https://www.python.org/ftp/python/3.10.6/Python-3.10.6.tgz

The output of the command above is the below, and the Python-3.10.6.tgz file is present within the working directory we executed in the above command.

You can use the ls command to check for the file we downloaded. Afterward, we can extract the Python-3.10.6.tgz file using the below command.

tar -zxvf Python-3.10.6.tgz

The code output is below and an extracted directory, Python-3.10.6.

Python-3.10.6/
Python-3.10.6/Mac/
Python-3.10.6/Mac/README.rst
Python-3.10.6/Mac/Icons/

Python-3.10.6/Mac/Icons/IDLE.icns
Python-3.10.6/Mac/Icons/PythonCompiled.icns
Python-3.10.6/Mac/Icons/ReadMe.txt
...

Now, let’s cd into the directory.

cd Python-3.10.6

Then, make a hidden directory using the command below.

mkdir ~/.localpython

Now, let’s configure the Python $PATH to allow us to access Python anywhere.

./configure --prefix=/home/lazycruise/.localpython

Here is where the error message pops up.

checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu

configure: error: in `/home/lazycruise/Python-3.10.6':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details

You can see the second to the last line with the error message, configure: error: no acceptable C compiler found in $PATH.

As we said earlier, the gcc compiler holds the C compiler we need to allow us to install Python successfully. So, let’s install the gcc compiler using the command below.

sudo apt-get install build-essential

The above command installs a meta-package that doesn’t install anything but provides a link to several other packages installed as dependencies. For build-essential, it installs everything required for compiling basic software written in C and C++.

These include the compiler we need, gcc, g++, libc6-dev, make, and dpkg-dev. We can write and run C and C++ software on Ubuntu with all these packages.

The following additional packages will be installed:

  libstdc++-9-dev libstdc++6 libtsan0 libubsan1 linux-libc-dev make manpages-dev

For other distributions or bases, the command will be different.

  1. CentOS, Red Hat

    sudo yum groupinstall "Development Tools"
    
  2. openSUSE

    zypper install --type pattern devel_basis
    
  3. Alpine

    apk add build-base
    

We can repeat our configure command with the complete command execution.

./configure --prefix=/home/lazycruise/.localpython

Now, it is successful. Afterward, we execute the command below, which builds the Python program and files from the source code extracted into the current working directory.

make

Finally, we execute this command to install the Python program.

sudo make install

Therefore, to solve the configure: error: no acceptable C compiler found in $PATH error message, all you need to do is install gcc, which comes with the meta-package, build-essentials on Ubuntu or similar distros.
