./configure syntax error on line 4556 in CentOS 7.9

Please correct me if this is wrong....

You are not wrong :(

For a newer g++ on CentOS 7 you can check Devloper Toolset 8

Can confirm that works, however OP will also need to install newer pkg-config e.g from rpm.pbone.net (usual disclaimer about replacing rpms from different releases)

yum install centos-release-scl
yum install devtoolset-8
scl enable devtoolset-8 bash
#wget your updated pkgconfig
rpm -U pkgconfig-0.28-3.fc20.x86_64.rpm
...build steps from readme...
# stenc --version
stenc 2.0.0 - SCSI Tape Encryption Manager

I hope the above proves useful to you @caiolopesdasilva

I face the same issue. I believe Centos 7.9 has too old a version of pkg-config (0.27.1) supposedly the functionality relied upon here was added in 0.28.0 ? Please correct me if this is wrong....

./configure: line 4556: syntax error near unexpected token `BASH_COMPLETION_DIR,'
./configure: line 4556: `PKG_CHECK_VAR(BASH_COMPLETION_DIR, bash-completion >= 2.0, completionsdir,'

Just for fun I snipped out the whole bash completion block from configure and was able to proceed. It broke at the make stage though. I believe GCC is too old on this platform, causing the error:
g++: error: unrecognized command line option ‘-std=c++17’

Centos 7 is EOL this year, however quite a few people will be stuck on this release for one reason or another so it would be a nice thing to support. I'm happy to volunteer my services as a tester on this platform (IBM HH LTO5 external SAS and a HH IBM LTO4 in a Dell Powervault autoloader)
