Compiling from source and Lua module

[Thor22]

Hi,
I tried to compile Cegui 5.0 form source package with this command :

./configure --disable-irrlicht-renderer --enable-toluacegui --enable-debug --with-default-xml-parser=XercesParser

so I get this summary:

********************************************************************************

but he doesn't want to compile the Lua's module. I checked my dependencies and I have these packages installed :

liblua40
liblua40-dev
liblua5.1-0
liblua5.1-0-dev
libua50
liblua50-dev
liblualib40
liblualib50
libtolua-dev
libtolua0
lua50

What is wrong ?

* Scripting:
* Building Lua scripting module: no

I personally have lua disabled, but I wonder if this is correct ??

[Thor22]

If he is disabled, Lua scripts won't be able to be loaded isn't it ?
But I have to load some Lua scripts in my project that is the problem

[Pompei2]

try to configure with

Code: Select all

--enable-lua-module

And if this does not work, take a look at what ./configure wrote in the console, there must be some reason he disabled lua. Maybe he can't find your lua headers or libs ? then you will need to specify the path to manually.

[Thor22]

Ok that is fix, just rename /usr/lib/pkgconfig/lua50.pc to lua.pc
But now I have some linking problems when I do "make":

I think it is because of a conflict between Cegui and Lua but I don't know what version of Lua I must use...

[Pompei2]

I think it is 5.1.x, but i'm not sure. search the forums I think there were similar problems in the past.

[Thor22]

I used 5.0 successfully and I just forget to link liblua.a ^^.
I am newbie on Linux I wonder what is the difference between static libraries ".a" and shared libraries ".so" ?

[Pompei2]

static libs .a are just archives that contain .o files (.o is compiled code that you can link, like .obj in visual studio), you can open .a libs with an archive tool (like ark). If you link with a .a lib, then all the library code is in your executable file.

shared libs .so are like windows .dll files, they are loaded dynamically and not linked into your executable. Like the dll's in windows, .so files cause a lot of trouble

[arbuckle911]

I just had this problem. I checked config.log and it turns out I had lua 5.1.1 and CEGUI wanted max 5.1. I went into the configure script and changed all the lua 5.1 strings to lua 5.1.2 and it compiled. I haven't tested it at all yet, but since CEGUI hasn't been updated (at least in a stable release) perhaps an official word should be put in from the developers that lua 5.1.1 is CEGUI safe or not.

Hi,
I'm interested in hearing about your success in using lua+cegui. I'm a fan of lua, tho i have not used it yet. I also love the cegui architecture. I think the two components may be very powerful together.

Please let us know as you keep moving this along.

Thanks for the effort.
