[Request] OpenBSD's calendar

fflarex · 2011-02-22 18:12:58

OpenBSD's calendar looks like a saner replacement for remind, and I'd like to try it out. I need help mostly because I don't understand CVS. Hopefully it builds on linux. Thanks in advance.

http://www.openbsd.org/cgi-bin/man.cgi? … ormat=html

EDIT: disregard this, I don't think it builds on linux. Shame, it looks pretty good.

I made a small try to get it working, inspired by some other BSD port PKGBUILDs
There seems to be a couple of Bu39 errors when the makefile tries to define some stuff relating to language.
If this part of the makefile is commented out, it stops at

.include <bsd.prog.mk>

I do not see any such file in the sources that have been checked out, so it is perhaps a dependency that needs to be installed first.
I tried with the libbsd and heirloom devtools. An alternative might be bmake (https://aur.archlinux.org/packages.php?ID=18416).

This is my current PKGBUILD

pkgname=openbsd-calendar-cvs
pkgver=280211
pkgrel=1
pkgdesc="reminder service from OpenBSD"
arch=('i686' 'x86_64')
url="http://www.openbsd.org/cgi-bin/man.cgi?query=calendar"
license=('custom:BSD')
provides=('calendar')
makedepends=('cvs' 'openssh' 'heirloom-devtools-cvs' 'libbsd')
#sources=('Makefile')
#md5sums=('3989368406b9b1c1d25bc999d6c07950')

__cvsroot="anoncvs@anoncvs1.ca.openbsd.org:/cvs"
__cvsmod="calendar"

build() {
    cd $srcdir

    CVS_RSH=ssh cvs -d $__cvsroot get -P src/usr.bin/$__cvsmod

    rm -rf build
    cp -ar $srcdir/src/usr.bin/$__cvsmod build
    cd build


#getting rid of some GNUisms
    export PATH=/usr/heirloom/bin:$PATH
    export DESTDIR=$pkgdir
#    export lang=  #only if you want to enable a different language. Check makefile and uncomment accordingly
#    cp $startdir/Makefile $srcdir/build/Makefile

    make LDLIBS=-lbsd
}

package() {
    cd build

    make install DESTDIR=$pkgdir
}

I will try with bmake rather than heirloom and see if that helps...

Update: bmake did the trick!
... almost.

Stuff move along quite nicely now, except that it complains about two missing header files. I could unfortunately not find a package providing these header files in Arch.

I have (naively, perhaps) simply copied these files from Bionic and NetBSD libc (the parent of Bionic, hopefully nothing linux-specific needed in there).
The problem I have at the moment is to make bmake understand that the two header files exist. I have tried copying them into the build directory but that does not seem to help.

updated PKGBUILD:

pkgname=openbsd-calendar-cvs
pkgver=280211
pkgrel=1
pkgdesc="reminder service from OpenBSD"
arch=('i686' 'x86_64')

__cvsroot="anoncvs@anoncvs1.ca.openbsd.org:/cvs"
__cvsmod="calendar"

build() {
    cd $srcdir

    CVS_RSH=ssh cvs -d $__cvsroot get -P src/usr.bin/$__cvsmod

    rm -rf build
    cp -ar $srcdir/src/usr.bin/$__cvsmod build
# copy missing header files to temporary build directory, taken from Android's BSD libc 'bionic'
    cp $startdir/*.h $srcdir/build/

    cd build

    bmake LDLIBS=-lbsd
}

package() {
    cd $srcdir/build

    bmake install DESTDIR=$pkgdir
}

update: I am currently patching .c file by .c file from <lib.h> to "lib.h" which seems to help... There should be a better way though... and I might need to find alternative header files.

update2: I decided to put it as an AUR right now so it is easier to follow the canges.
I believe that it will be possible to make it build...eventually.
https://aur.archlinux.org/packages.php?ID=47044

If you want to take over the build, just notify me and I will disown it.

After all .c files got updated to use a local header file, the next issue seems to be with "calendar.h"

If I understand the errors OK it seems like u_long, time_t and f_time are not understood. I need to check if these are written differently under linux.

EDIT: the "time" errors could be solved by including time.h in the .c files complaining

The remaining error at the moment is at row 113 in calendar.h : extern u_long julian;

this one causes errors in a number of different .c files.

time_t is defined by sys/types.h. You'll need to find yourself a copy of tzfile.h and change the #include <tzfile.h> to #include "tzfile.h" (or modify the include path). That at least gets you past compilation and onto the linking...

/home/noclaf/build/openbsd-calendar-cvs/src/build/calendar.c:173: undefined reference to `setusercontext'
day.o: In function `isnow':
/home/noclaf/build/openbsd-calendar-cvs/src/build/day.c:292: undefined reference to `arc4random_uniform'
collect2: ld returned 1 exit status

edit: arc4random_uniform isn't part of libbsd nor is it part of calendar. Going to leave this here for the night...

Thanks for helping out. I figured out the thing about changing to "tzfile.h" - hence all the small patches in my AUR linked above.
The calendar.h problem will however need some further investigation...

EDIT @falconindy

Now I have caught up with you and get the same errors:

--- calendar ---

*** [calendar] Error code 1

I will google a bit and see if I can find a solution. My PKGBUILD (https://aur.archlinux.org/packages.php?ID=47044) is quite hacky unfortunately. Making it nicer is also on the to-do list.

according to this ubuntu manpage that I found, arc4random should be a part of libbsd
http://manpages.ubuntu.com/manpages/luc … dom.3.html

I wonder if I have been calling the libbsd in a wrong way or if I explicitly need to include libbsd in the .c files...

falconindy · 2011-03-04 18:06:38

Hmmmm, it does seem to be part of libbsd:

$ readelf -s libbsd.so.0.2.0 | grep arc4random_uniform
80: 00000000000026d3    95 FUNC    GLOBAL DEFAULT   12 arc4random_uniform@@LIBBSD_0.2
228: 00000000000026d3    95 FUNC    GLOBAL DEFAULT   12 arc4random_uniform

The pkg-config file included with libbsd doesn't mention any extra flags besides -lbsd (uses standard linker/include paths).

What I'm not seeing is the header that defines the prototype for arc4random_uniform (there are other arc4random exports), but if that were an issue it'd be hit by the compiler, not the linker.

It is very strange indeed.
I found this patch on Gentoo:
http://sources.gentoo.org/cgi-bin/viewv … iew=markup

so I figured that perhaps the arch4random_uniform is part of the API break that is mentioned in a number of depreciated header files in libbsd.

Inspired by that, I made a libbsd-git variant applying this patch:
https://aur.archlinux.org/packages.php?ID=47112

This does not seem have helped at all, since my errors are still:

--- calendar ---
cc -pipe   -o calendar  calendar.o io.o day.o pesach.o ostern.o paskha.o 
calendar.o: In function `main':
/home/jens/Dev/Arch/openbsd-calendar/src/build/calendar.c:173: undefined reference to `setusercontext'

bmake: stopped in /home/jens/Dev/Arch/openbsd-calendar/src/build
1 error

bmake: stopped in /home/jens/Dev/Arch/openbsd-calendar/src/build
    Avbryter...

EDIT: I wonder if bmake takes the argument LDLIBS and whether this might be the problem... I have tried with the variables LOADLIBES and LIBS without any change in the end result.

EDIT2: The arc4random_uniform is a known bug in libbsd
https://bugs.freedesktop.org/buglist.cg … uct=libbsd
The patch I applied above should however solve it so I am a bit confused.

EDIT3: I have experimented with changing the "bmake -LDLIBS=-lbsd"
to "bmake -LDLIBS=-lbsd CC="gcc -I /usr/include/libbsd -I /usr/include/libbsd/bsd"
This changes the outcome quite a bit, where it seems like the libbsd stuff is being used (finally). Now there seems to be issues with time.h though... sigh...

I give up on this. I really do not know what to do next to get forward on compiling this thing

I disown my AUR:
https://aur.archlinux.org/packages.php?ID=47044

If you want to try solving this one, just adopt this package.

fflarex · 2011-03-17 19:23:42

Thanks for the effort, anyway. I was away from the forums for a while and it's kind of surprising to me that so much effort was put into my request while I was gone.

W.F.Cody · 2011-03-18 07:09:55

No probs. I enjoyed the challenge and learned a few things along the way. I hope someone smarter/more experienced than me will go the extra mile to get it working for you

W.F.Cody · 2012-06-03 10:16:16

Sorry about resurrecting such an old thread.

I just wanted to share that this package now builds!
