I was trying to clean up my code and put some things into the luaprinter constructor so they would be done automatically done, but it seems to make it not work. So strange. And printfs in the constructor don't appear until I exit mame.


The printfs that make "Scooby 8510" and "Scooby 8511" don't appear until exiting mame, yet the initvalue gets set properly to 3333.

But if I move routines into the constructor all sorts of weird things happen. So I'll leave it outside for now since I've been fiddling with this for a day...gcc problems on Ubuntu?


Code
luaprinter(device_t & thisdevice, int testvalue){ 
        m_lp_mydevice = &thisdevice; 
        time(&m_lp_session_time);  
        initvalue = testvalue;
        printf("\n\nInit Luaprinter Scooby %d\n",testvalue);
        initvalue = 33333;
        };




Code
[MAME]> lp = manager:machine().printers for i=1,#lp do print( lp[i]:getprintername(), #lp, lp[i]:getinitvalue(), lp[i]:simplename()) end

after putting code in the constructor I get strange behavior:

Code
[MAME]> print( manager:machine().luaprinters[1]:getprintername(), #manager:machine().luaprinters)
error: 	std::bad_alloc
[MAME]> print( #manager:machine().luaprinters)
