I am giving it a go at compiling lsyncd on Mac OS X (Lion) and I got a little stuck at my configure script not being able to locate my lua libraries:-
calvin$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking for style of include used by make... GNU
checking dependency style of gcc... gcc3
checking whether make sets $(MAKE)... (cached) yes
checking pkg-config is at least version 0.9.0... yes
checking for LUA... no
checking for LUA... no
checking for LUA... no
checking for LUA... no
configure: error: Package requirements (lua >= 5.1.3) were not met:
No package 'lua' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LUA_CFLAGS
and LUA_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
I do have lua installed via macports.
calvin$ lua -v
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
calvin$ which lua
/opt/local/bin/lua
UPDATE
I know for sure that the lua.pc file is located in:
calvin$ sudo find /opt/local -name "lua.pc"
/opt/local/lib/pkgconfig/lua.pc
and so, gone to the extent of explicitly specifying the PKG_CONFIG and PKG_CONFIG_PATH environment variables in my .bashrc file and sourcing it. Like this:
export PKG_CONFIG="/opt/local/lib/pkgconfig:$PKG_CONFIG"
export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"
What do I need to do to set the correct PKG_CONFIG_PATH environment variable so that my configure script can find lua?
UPDATE #2
So I added in
export LUA_CFLAGS="/opt/local/include"
export LUA_LIBS="/opt/local/lib"
in my .bashrc file, and with that done, I can now run ./configure --without-inotify successfully, with the following output:-
calvin$ ./configure --without-inotify

configure: creating ./config.status

config.status: config.h is unchanged

Unfortunately, running make doesn't work as it seems that the lsyncd.h header file is unable to include lua.h.
