Lua dependency when installing from SVN

[seahen]

scons keeps on reporting the following when I try to build the newest trunk of Wesnoth:

Checking for Lua development files version 5.1... (cached) no
Client prerequisites are not met. wesnoth, cutter and exploder cannot be built.

Although the rest of the script appears to run fine, wesnoth -v still gives me the old version. This happens even after I install liblua-5.1-0-dev. What other packages do I need, and why can't I find the prerequisites for the trunk build documented anywhere?

Note that the result for lua check is cached. You might want to try:

Code: Select all

scons --config=force

That makes the least sense to me of any design decision I've seen in a program I've worked with.

Code: Select all

scons --config=force

When I do that, I get

/usr/bin/ld: cannot find -llua
collect2: ld returned 1 exit status
scons: *** [wesnothd] Error 1
scons: building terminated because of errors.

Now what's wrong?

This is why we offer cmake and autotools as equally well-maintained alternatives.

No idea what may be wrong. It works for me after installing liblua5.1 and its -dev counterpart in Debian lenny in parallel with liblua50, but for other people the recipe seems to work at random.

What's in build/config.log? Perhaps there's bogus "lua.pc" file somewhere?

cached here means that the test program was up-to-date. It generally should automatically figure out to rebuild the test program, e.g. if compile flags or its dependencies change.

I tried the latest from trunk with autoconf. I think it was the autogen.sh before configure

Checking for LUA... checking for LUA... configure: error: Package requirements (lua5.1 >= 5.1) were not met:

No package 'lua5.1' 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 did not have time to look at this, and it may be harmless. The ony question is: Is lua(whatever it is) included in the trunk(in which case it should be a configuration issue) or does one need to grab it and install it separately?

Lua is an external package, you have to install it separately. For install, if you system is Debian-related, just install the liblua5.1-0-dev package.
