Home Page Forums MAME Non-Windows MAME Support building 0.161 using system libs

Hello,

how do I build mame using system libs (expat, zlib, etc.) after the buildsystem overhaul? Is it supported?

I see the makefile switches are gone so I assume the answer to Belegdol's question is no.

Let's make a step further: I'm going to write some patches for Ubuntu, as using bundled libraries in official packages is deprecated whenever possible (and other distros have similar recommendations).

I'd like to make things the right way and have them merged upstream, so I'm asking for blessing in

• splitting scripts/src/3rdparty.lua into several lua scripts, one for each library
• adding a switch in the makefile for each library and have it include the lua script OR set LDFLAGS as appropriate, i.e.
  
  Code:

  ifndef USE_COMMONLIB_EXPAT
  SCRIPTS += scripts/src/3rdparty/expat.lua
  else
  LDFLAGS += -lexpat
  endif
  

Any further suggestion is welcome, thanks.

Although I don't think the recommendation is always good, I agree that it should be user-selectable... but wouldn't it be better to call it USE_SYSTEM_EXPAT etc.?

yes

also, the variable name is actually LDOPTS (not LDFLAGS)

Yeah. It's probably still better to do the necessary changes in the respective LUA scripts rather than in makefile, mainly because makefile is just "the vehicle to drive GENie" which will then take care of the generation of system-dependent make rules or project files (and portability between toolchains / OSs).

I see.

What about something like this? Still needs some testing, though.

I'd say that's probably better, but I'm not a MAME-dev .

Basing on wallyweek's work I have put together the code to build almost everything as system lib:

Feedback is welcome. Also, how would I go about submitting this?
