Problem with vice 2.4 on ubuntu 16.04 (and lubuntu)
I found that there is a problem with Vice 2.4 under ubuntu (aquired with sudo apt-get install vice), in particular using the krill loader (none of my previous multi-load demos worked either, and they were tested on real C64). My solution was to compile the 2.4 x64sc from source (instead of using the ubuntu build), and that worked perfectly (however the GUI is somewhat "different").
Anyone got a clue on how to build the x64sc from source with the proper user interface? Anyone else have had similar problems?
I did find that there was previously a problem with setting $dd00 with the loader (any workaround btw?), but I was under the impression that it was fixed (and it does work on real HW). |

Just tried "Frantic 3: Nightmare" with the vanilla VICE 2.4 that comes with Mint and it seems to work fine. I suppose you had True drive emulation on...? |

I found a problem with a lib_free of a temporary variable (main.c:241), apparently the code manages to overwrite the memory, thereby corrupting the next memory segment. If you set the malloc size (main.c:225) to a higher value (i.e. 250, since we do have a LOT of memory these days), the problem disapeared for me.
I also fixed (perhaps) a problem with ambigous notting in parallel-trap.c, but not sure if this is the intended functionality or not. Anyway the warning is quite obvious, so the Vice team should pick that up anyway. |

Should be fixed in R31750

Not sure what you mean with 'ambigious notting' or 'I fixed'? If you have a patch, feel free to submit it to the tracker: https://sourceforge.net/p/vice-emu/patches/
Preferably a simple diff of the file(s) you changed. |

also dont assume other people see the same warnings as you do - as that heavily depends on your global CFLAGS and also on your compiler version. i get no warnings at all when building vice, for example :) |

parallel-trap.c: line 101
"if (!p->isopen[channel] == 1)"
should perhaps be:
"if (!(p->isopen[channel] == 1))"
or
"if ((!p->isopen[channel]) == 1)"
? |

Bah, not enough negations per line, this should be
if ((!p->isopen[channel]) != 0) |

if ((!(p->isopen[channel]) != 0) ? !false : !true) |

Quoting the Bible:
Kernighan and Richie, Book 2, verse 53 tells us that dereferencing (->) has higher precedence than negation (!). So the code is correct, although I would also add parenthesis to be sure. |

Fuck, it's not correct at all. Who wrote this?
K&R are still gods though, phew. |
