Re: [Snort-users] --enable-open-appid failing even though luajit is installed

Avery,


Here is what I did on FreeBSD 10.2 which succeeded with me:


./configure --enable-sourcefire --enable-open-appid luajit_CFLAGS="-I/usr/local/include/luajit-2.0" 
luajit_LIBS="-L/usr/local/lib -lluajit-5.1"


# which luajit

/usr/local/bin/luajit

# which lua51
/usr/local/bin/lua51

I did see this one but from what I can see freeBSD 10.2 is not using pkg-config, but I could be wrong.

Thank you,
Avery

Hi,
Back in May I had issues installing on OS X, with --enable-open-appid complaining about LuaJIT.  I sent my solution to 
the list.  Maybe this will help?  Text from my response:

Hi,
Well, this is fun.  I started picking apart the configure script again to figure out which pkg-config commands it was 
running.  I then realized I didn't have pkg-config installed at all, which was actually evidenced in the script output. 
 Just before the "checking for luajit... no" line, it also said "checking for pkg-config... no".  Further, grepping for 
PKG_CONFIG variables in config.log shows that PKG_CONFIG and PKG_CONFIG_LIBDIR were empty.  I installed pkg-config via 
brew, reran my configure script with options, and voila.  It configures and compiles just fine!

To further validate, I uninstalled pkg-config, reran configure, and it failed as expected.

Moral of the story - pkg-config is required for the configure script on OS X, at least when enabling OpenAppID.

Thanks for the prompting to check on pkg-config.


For future reference, this was what my reply was GOING to be before I did that one last configure after installing 
pkg-config:

"""
I believe this means that pkgconfig can find LuaJIT:

$ pkg-config --libs luajit
-L/usr/local/lib -lluajit-5.1

And

$ pkg-config --list-all | grep -i lua
lua5.2               Lua - An Extensible Extension Language
lua-5.2              Lua - An Extensible Extension Language
luajit               LuaJIT - Just-in-time compiler for Lua
lua                  Lua - An Extensible Extension Language


If I'm pulling the right lines from configure script, I think this also means yes it can find LuaJIT:

$ pkg-config --print-errors --cflags --libs luajit
-I/usr/local/include/luajit-2.0 -L/usr/local/lib -lluajit-5.1
"""

In my case I also had to install lua51 (which may be unnecessary). Also you need to set the "luajit_CFLAGS" and 
"luajit_LIBS" when compiling Snort.

I'm trying trying to install Snort 2.8 on FreeBSD with the --enable-open-appid configuration option. It's failing 
complaining that luajit is not installed. I did install luajit 2.0.4 from source with default options and verified with 
"which luajit", this is the response "/usr/local/bin/luajit". There does not seem to be an option for 
"--with-luajit-libraries=DIR" in the ./configure --help.

checking for luajit... no

  ERROR!  LuaJIT library not found.....

Am I missing another dependency?

Thanks,


Avery
