Hello,

I want to test bachefs file system on CentOS 7.
~$ cat /etc/system-release CentOS Linux release 7.6.1810 (Core)

I’m following the bcachefs howto: https://bcachefs.org/Howto/.

Having a problem trying to complete make && make install of the bcache-tools. After going through all the dependencies and insuring they are installed on Cent 7, I get the following output on make && make install:

Package blkid was not found in the pkg-config search path. Perhaps you should add the directory containing `blkid.pc’
to the PKG_CONFIG_PATH environment variable No package ‘blkid’ found Package uuid was not found in the pkg-config search path. Perhaps you should add the directory containing `uuid.pc’
to the PKG_CONFIG_PATH environment variable No package ‘uuid’ found Package libsodium was not found in the pkg-config search path. Perhaps you should add the directory containing `libsodium.pc’
to the PKG_CONFIG_PATH environment variable No package ‘libsodium’ found Package libzstd was not found in the pkg-config search path. Perhaps you should add the directory containing `libzstd.pc’
to the PKG_CONFIG_PATH environment variable No package ‘libzstd’ found Makefile:42: *** pkg-config error, command: pkg-config –cflags “blkid uuid liburcu libsodium zlib liblz4 libzstd”. Stop.

The packages are installed but I’m not certain how to satisfy pkg-config and place them in the correct path.

The pkg-config man page states –
ENVIRONMENT VARIABLES
PKG_CONFIG_PATH
A colon-separated (on Windows, semicolon-separated) list of directories to search for .pc files. The default directory will always be searched after searching the path; the default is libdir/pkgconfig:datadir/pkgconfig where libdir is the libdir for pkg-config and datadir is the datadir for pkg-config when it was installed.

On my installation, the current path seems to be:
~$ pkg-config –variable pc_path pkg-config
/usr/lib64/pkgconfig:/usr/share/pkgconfig

~$ echo $PKG_CONFIG_PATH
<>

Using locate, I do not find any of these files, so how do I properly add the packages to the path
