Installation methods

[Squro AWM]

HI,

 I am new to TRex. While searching for the installation steps (on Ubuntu 22.04 LTS), I found 2 different methods.

 Method I:

download: git clone  https://github.com/cisco-system-traffic-generator/trex-core.git and build.

 cp trex-core-2.97.tar.gz /opt

tar zxvf trex-core-2.97.tar.gz
cd trex-core-2.97/linux_dpdk

./b configure 

./b build

 

Method II :

Latest (stable) release:

[bash]>mkdir -p /opt/trex
[bash]>cd /opt/trex
[bash]>wget --no-cache https://trex-tgn.cisco.com/trex/release/latest
[bash]>tar -xzvf latest

From <https://trex-tgn.cisco.com/trex/doc/trex_manual.html#_download_and_installation>

 

 What is the difference between these 2 types of installation.

What is trex-core?

 

Can anyone pls help me to understand this?

Thanks in advance.

Method 1 is for developers who want to make changes and test.

Method 2 is for users, already compiled, only to use.

Thanks,

Hi,

Is there the difference between the two tar file?

I tried building one from scratch and I noticed that method 1(building from source code) has more files compared to method 2(Downloading the tar.gz).

Example for v3.03:

Method 1 has these files which Method 2 doesn't have:

emu-sim
emu-script
emu_daemon_server

azure_trex_setup.sh

cps_ndr.py

Method2 has these files which method1 doesn't have:

trex_client_v3.03.tar.gz

Can you tell me the how to build to get similar result to the release

[Rashi Krishna]

These are the steps I used to create the tar file:

```

cd /tmp/trex-core/linux_dpdk

./b configure

./b build

cd /tmp/

tar -hczf v3.03.tar.gz -C /tmp/trex-core/scripts .

```

Can you check if this is the correct way.

Oh..found out there was a script to create package.

./b pkg
