Error compiling 3.4.0 agent in FreeBSD

[C. L. Martinez]

Hi all,

I am installing new 3.4.0 agents on my FreeBSD systems, but it seems ¿gcc? is needed:

- Running the Makefile

I was report smae problem some time ago https://groups.google.com/forum/#!searchin/wazuh/freebsd|sort:date/wazuh/HZkgAAW9IbM/7GWc140DBwAJ, and for release 3.3.X all was working ok (if I remember well) ... Is this a regression?

Thanks.

Hi CL,

You need GNU Make and a C compiler to run the Wazuh installer since we do not provide packages for FreeBSD at this moment.

As we told in the mail thread you mention, you can use GNU C Compiler (gcc) or Clang.

If you want to use Clang, run Make manually before launching the installer (following the steps in the old thread:

1. Compile Wazuh using Clang and disabling Lua (it's not supported by Clang):

gmake -C src TARGET=agent CC=clang LUA_PLAT=none

2. Set up a binary installation to prevent the installer from running the compiler:

Edit etc/preloaded-vars.conf and set USER_BINARYINSTALL to "y":

# If USER_BINARYINSTALL is set, the installation
# is not going to compile the code, but use the
# binaries from ./bin/
USER_BINARYINSTALL="y"

3. Run the installer:

./install.sh

On the other hand, if you want to use gcc to compile Wazuh, follow these steps:

1. Install gcc:

pkg install gcc

2. Run the installer:

./install.sh

Hope it help.
