Hi, I get an issue when I try to install nrpe service. I am following the instructions from (https://access.redhat.com/documentation ... eph-nagios)
we are red hat 9

error:

Can you help me to avoid this?

Hey @Juairy15, thanks for reaching out. It looks like there are problems with OpenSSL 3.0. Here are some things I'd try off the bat:

Check if you have an older version of OpenSSL available in your repositories or you can download it:

Code: Select all

sudo yum install openssl1.1-devel

And using this older version:

Code: Select all

export PKG_CONFIG_PATH=/usr/local/openssl1.1/lib/pkgconfig 
export LD_LIBRARY_PATH=/usr/local/openssl1.1/lib 

Then try make clean and make all to clean the previous build and try again.

There are also compatibility libraries you can try if that doesn't work:

Code: Select all

sudo yum install compat-openssl10-devel
