These are usually located in /usr/share/aclocal/pkg.m4.

What are PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR?

PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR are environment variables used by the pkg-config tool to locate and search for package configuration files.

PKG_CONFIG_PATH specifies a list of directories to search for .pc files, which contain information about installed packages.

PKG_CONFIG_LIBDIR specifies the directory where pkg-config looks for its own libraries.

Both of these variables are used by developers to ensure that their software can find and use the required libraries and dependencies during compilation and linking.

Could not locate the pkg-config autoconf macros. These are usually located in /usr/share/aclocal/pkg.m4.

As an AI language model, I cannot access your system files, but I can provide you with some general troubleshooting steps:

1. Check if pkg-config and autoconf are installed on your system. If not, install them using your operating system's package manager.

2. If they are already installed, try reinstalling them.

3. Check if the file /usr/share/aclocal/pkg.m4 exists. If not, create it or try reinstalling pkg-config.

4. Make sure that the path to pkg.m4 is included in the ACLOCAL_PATH environment variable. You can add it by running the following command in your terminal:
export ACLOCAL_PATH=/usr/share/aclocal

5. If none of the above steps work, try searching for alternative locations of pkg.m4 on your system and add them to the ACLOCAL_PATH variable.

6. If you are still having issues, seek help from the community or the developers of the software you are trying to build.

libtoolize: error: '/usr/share/aclocal/libtool.m4' does not exist.

This error message indicates that the libtoolize command is unable to find the libtool.m4 file in the /usr/share/aclocal directory. This could be because the libtool package is not installed on your system or the file is missing or has been moved to a different location.

To resolve this issue, you can try installing the libtool package using the package manager of your Linux distribution. For example, on Ubuntu, you can run the following command:

sudo apt-get install libtool

If the package is already installed, you can try locating the libtool.m4 file and updating the aclocal search path accordingly. You can use the following command to locate the file:

sudo find / -name libtool.m4

Once you have located the file, you can update the aclocal search path by adding the directory containing the file to the ACLOCAL_PATH environment variable. For example, if the file is located in /usr/local/share/aclocal, you can add the following line to your .bashrc file:

export ACLOCAL_PATH=/usr/local/share/aclocal

After updating the environment variable, you can try running the libtoolize command again and check if the issue is resolved.
