I'm trying to install Lsyncd on Ubuntu 10.4 LTS but i get some error :

Or I know I have Lua installed :

# lua -v
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio

I read on several forums that I need a lua.pc file but i can't find it. Does anyone know how to proceed?

Thank you

EDIT : SOLVED

Some packages were missing ;)

apt-get install liblua5.1-0-dev liblua50-dev liblualib50-dev

If compiling software yourself, you should install not only the runtime (lua5.1) but also the development packages (liblua5.1-0-dev). That package contains the lua5.1.pc file.

It's also in the lua source distribution.

try sudo apt-get install liblua5.1-0-dev

I met the same problem on my debian jessie while trying to compile luacrypto.

The problem is, in configure.ac, luacrypto try the following:

PKG_CHECK_MODULES([LUA], [lua])
LUALIBDIR="`$PKGCONFIG --variable=libdir lua`"

The problem is that, since there's multiple versions available, you need to specify which one you want, here is my output for pkg-config --list-all:

root@test-stream:~/luacrypto# pkg-config --list-all|grep -i lua
lua-5.1-c++      Lua - Lua language engine
lua-5.1          Lua - Lua language engine
lualib50         lua50 - The Lua 5.0 programming language addon libraries
lua5.1           Lua - Lua language engine
lua5.1-c++       Lua - Lua language engine
lua51            Lua - Lua language engine
lua50            lua50 - The Lua 5.0 programming language
lua51-c++        Lua - Lua language engine

I just modified top-level configure.ac for luacrypto this way:

diff --git a/configure.ac b/configure.ac
index b6b9175..20ea20c 100644
--- a/configure.ac

 # lua libdir

Then autoreconf -i (you need autoconf & automake for this) and it works !

It seems you have installed Lua.

The missing lua5.1.pc file will be present in the etc folder To install the other missing packages try the below command

sudo apt-get install libreadline-dev
