What library am I missing?
 

I get this error with several programs I try to compile.

line 14 :
I think, gpoll.h was introduced in glib-2.19.0 .
( The current stable is 2.22.2 ).

Thus no ' gpoll.h ' in Slackware 12.2 or Slackware 13.
.....

glib is what is causing your problems.
Googling tells me glib has caused problems with building packages before.
You may have to upgrade or downgrade glib as what you're trying to build may not be compatible with the glib you have installed.

Dang, I had these updated when I built GIMP. They were downgraded when I forgot to de-select them when updating with slackpkg. Thanks all.

slackpkg can blacklist packages that you don't want automatically updated.

I don't necessarily want to blacklist any particular package, as it may be upgraded to a newer rev than I already have installed one day. I would like to see it be more sensitive to versioning and not "upgrade" to a lower rev.

AFAIK to check for upgrades to be done, Slackpkg looks for packages in official Slackware directories only, in the order given by the PRIORITY parameter, set up in /etc/slackpkg/slackpkg.conf. This suppose that any "not official" package should be upgraded, disregarding any other consideration.

Didier Spaier You are correct AFIK as well. I certainly understand why it is written that way. I was merely offering an opinion. I certainly need to pay more attention to what is going to be upgraded before I push the button.

I must admit that way too often I do not read before pushing the button either, even when typing commands as root in a shell :confused:

That's why I edited /etc/slackpkg/slackpkg.conf recently to get the ONOFF=OFF behaviour...

Good idea, thanks!
