Problem compiling nagios core on rocky linux 9 (i.e. gcc 11)

[MortenSickel]

I am trying to compile nagios 4.5.9 on a rocky linux9 box.

I have cloned the nagioscore git repository and checked out the nagios-4.5.9 release

Then I do ./configure that runs without any problems, but make all stops on

Code: Select all

In the end it spits out a few more warnings and unknown storage size errors. It compiles fine on another server with centos7, i.e. gcc 4.8.5 I guess this may have to do with altered header files in rocky9, or maybe there is something I have not installed?

Thanks for reaching out,

I was able to manually trigger your issue by running configure like so CFLAGS=-std=c99 ./configure, are you doing something similar? Otherwise I can look into why this CFLAG is getting added.

[MortenSickel]

Well spotted and the problem was entirely my fault.

I had some problems compiling it earlier on and set CFLAGS to try to fix it. Then I forgot the CFLAG setting.

unset CFLAG solved my problem

Thanks!

Nice! I'm glad that resolved your issue!
