Dwm 5.9 Compilation issues

Ypnose · 2011-09-12 14:21:32

Ok guys, I really need your help.

I am currently with dwm 5.8.2 (everything's fine) and I downloaded 5.9 via ABS.

I launched a makepkg under ~/dwm. And next, I tried to apply this patch called pertag2. diff: https://github.com/simongmzlj/dwmhacks/ … rtag2.diff
It succeeded. Used:

patch -p1 < pertag2.diff

And I modified my config.h as jokerboy suggested me here: https://bbs.archlinux.org/viewtopic.php … 45#p960545

I haven't others patches.

But when I try to compile it, I got many errors messages.

dwm build options:
CFLAGS   = -std=c99 -pedantic -Wall -Os -I. -I/usr/include -I/usr/include/X11 -DVERSION="5.9" -DXINERAMA
LDFLAGS  = -s -L/usr/lib -lc -L/usr/lib/X11 -lX11 -L/usr/lib/X11 -lXinerama

 *
 * dynamic window manager is designed like any other X client as well. It is
 * driven through handling X events. In contrast to other X clients, a window
 * manager selects for SubstructureRedirectMask on the root window, to receive
 * events about window (dis-)appearance.  Only one X connection at a time is
 * allowed to select for this event mask.
 *
 * The event handlers of dwm are organized in an array which is accessed
 * whenever a new event has been fetched. This allows event dispatching
 * in O(1) time.
 *
 * Each child of the root window is called a client, except windows which have
 * set the override_redirect flag.  Clients are organized in a linked client
 * list on each monitor, the focus history is remembered through a stack list
 * on each monitor. Each client contains a bit array to indicate the tags of a
 * client.
 *
 * Keys and tagging rules are organized as arrays and defined in config.h.

Try this one: http://ompldr.org/vYWJoNg/pertag2.diff

livibetter · 2011-09-12 14:49:19

The diff you use rename tile() to ntile(), you should not have tile in your config.h. The rest of errors probably relate to what the diff has nerfed, or should be gone once you fix that tile.

I think you should stay on 5.8.2 until all the patches have support for 5.9 if you can't patch on patch on your own.

(edit) that github repo has issues, it might be good idea to create issue if that patch really have compatible issue with 5.9. That would benefit all other patch users.

Jokerboy: It works fine. A big thanks, man

livibetter: you're right. It's also difficult because patches have same names but they're different and/or don't work with current version. Jokerboy provided a good patch so we should share it.
And what's the difference between tile and ntile or bstack and nbstack?
