Bug 118717 – net-wireless/swscanner-0.2.2 (new ebuild)

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Christoph Vogtländer 2006-01-11 15:56:55 UTC]

Simple Wireless Scanner (SWScanner) is an application for Linux environments designed for scanning, configuring, and (in general) managing wireless networks. SWScanner is also a powerfull wardriving tool, and has a high level of compatibility with NetStumbler, a similar and well-known application designed for other operating system.

Only tested on ppc so far.
There is a problem with storing data. swscanner needs qsqllite. If qt is not compiled with the sqlite USE-Flag the following error will occur when starting the app:
QSqlDatabase: QSQLITE driver not loaded
But scanning works.

I don't know how to test if qt was compiled with a certain use flag in the ebuild, though. Anybody? AFAIK this is not possible with DEPEND.
Or just print out a warning with ewarn at the end of the install that qt needs to be build with sqlite?

I suggest net-wireless/swscanner

pkg_setup() {
	if ! built_with_use x11-libs/qt sqlite; then
		eerror "QT needs to be installed with USE=sqlite"
		eerror "for ${PN} to run correctly"
		die "remerge x11-libs/qt with \"USE=sqlite\"
	fi
}

Cool, never thought it would be so easy :-)
This should definitely go into the docs! It is not in the man page of ebuild or eutils, nor in the Ebuild-Howto...
Or am I looking wrong and using outdated docs?

Well, we try to avoid this unless necessary, use-based deps are the real solution, the above is just a workaround for portage lack of features (see Bug 2272). See eutils eclass, also http://dev.gentoo.org/~plasmaroo/devmanual/ is a good reading if you want to write ebuilds.

new swscanner-0.2.2.ebuild

i changed over Christoph's ebuild to use the kde.eclass and fixed up some bits.

- DESCRIPTION should be 80 characters max
- RESTRICT="nomirror" should only be used for files Gentoo cannot legally host
- put QT sqlite detection in pkg_setup as per Jakub
- SLOT and IUSE have to be present, even if they're empty
- added kdelibs to DEPENDS

the kdeenablefinal USE flag breaks compilation, so it's force disabled.  also 
--with-extra-includes=/usr/include/libshp/ would be overridden by kde.eclass so i made a simple patch to src/shapehandler.h to fix the include problem.

we could make the HTML documentation dependant on the doc USEflag, but that's up to the maintainer.

[Comment 7 Walter White 2006-05-15 11:18:37 UTC]

on both my 64bit desktop and 32bit laptop, I get this error:

64bit system: /usr/lib64/.libs/libshp.so
32bit system: /usr/lib/.libs/libshp.so

no such file or directory

That is with the patch, so it should work.  The library is installed, but not in that place.  How do I tell it to look somewhere else?

[Comment 8 ema 2006-08-31 16:05:15 UTC]

ln -s /usr/lib64/libshp.so /usr/lib64/.libs/libshp.so   

[Comment 9 Juergen Nagel 2006-09-26 14:05:42 UTC]

Walter's problem has to do with an error in /usr/lib/libshp.la.

In /usr/lib/libshp.la (from sci-libs/shapelib-1.2.10-r1) there's the section:
   # Is this an already installed library?
   installed=no

Changing "no" into "yes" fixes the problem temporarily.
(Solution found at http://www.sane-project.org/old-archive/2000-11/0003.html)

The real problem, however, lies in the incorrect generation of libshp.la by the shapelib build process.

Requires qt 3 and upstream is dead.
