Re: Snort3 installation problem on Ubuntu 20.04 : CMake Error: The following variables are used in this project, but they are set to NOTFOUND

Dear Dave,


I have too Ubuntu focal 20.04 if you happen a problem with flex this isn't for all people because my flex works good but I haven't try to built flex with snort,

I can help you if you want the weekend only because the week I haven't a computer,

Because you use the package flex this isn't built with cmake you can forgot my e-mail previous,

This is interesting because on my snort I haven't try to built flex I will try but this weekend I am in holiday sorry I haven't access to my system Ubuntu,

What version of snort you try to built ?

Dear Joel this person try to built flex with snort can you share with us what is the location of flex installation on a system linux or can you answer what is the goal of flex on snort because there are some flex on GitHub but I don't understand what flex take, (I can run 'locate flex' but work a flex from GitHub can be interesting and a gflex packaged isn't a program installed on the snort source),

Thanks you in advance Joel,

Thanks you in advance for your question Dave,

Regards.


Dorian Rosse.

Hello Dorian,

Thank you for your reply. I have Flex installed from the current apt
package (version 2.6.4) on Ubuntu 20.04, whereas I downloaded Snort3 via
'wget
https://github.com/snort3/snort3/archive/refs/tags/3.1.28.0.tar.gz'

Similarly, gperftools is installed manually via 'wget
https://github.com/gperftools/gperftools/releases/download/gperftools-2.9/gperftools-2.9.tar.gz'

Libdaq is also cloned from git (and compiled manually): 'git clone
https://github.com/snort3/libdaq.git'

The various other dependencies are installed via apt: 'apt install
build-essential libpcap-dev libpcre3-dev libnet1-dev zlib1g-dev luajit
hwloc libdnet-dev libdumbnet-dev bison flex liblzma-dev openssl
libssl-dev pkg-config libhwloc-dev cmake cpputest libsqlite3-dev
uuid-dev libcmocka-dev libnetfilter-queue-dev libmnl-dev autotools-dev
libluajit-5.1-dev libunwind-dev'

I will carefully re-read your message and Adrian Mamolea's message in
the coming hours, and will write back to the list. Thank you again,
guys, for your help.

With all best wishes,

Dave
