This is my question, I can install programs from source code, but I don´t know how uninstall it.

How is the correct way of uninstall this kinds of programs???

Thanks.

You should be able to go back into the directory you compiled the source from and type as su or root:

make uninstall

If make uninstall dun work try:

rm -rf /place/where/it/was/installed

erm.. and what if it was installed in /usr/local/bin? i think maybe you should be a little more careful about advice... unless you're saying that on purpose... which is fair enough

Well if make uninstall didn't work, then you got to check the makefile for every file that it installed, and there might be more then just a simple file in usr/bin or /bin

for example man pages, and all of these files that were compiled then moved to the specific locations need to be removed. Uninstalling is a hastle, but hopefully the person who made the program added an uninstall procedure in the MAKEFILE, so

make uninstall

should work. Otherwise you got to do what I said above, I think that is. There might be a better way to delete though, and I don't know it yet.

so does this mean i should keep the source of every piece of crap i download?

well if it's crap then you're not going to want it are you? generally tho, yes that is the general idea. you can infact just keep the Makefiles for the source but picking them out from a source tree is a bit of a waste of time. The general idea tho is that you have plenty of space and like keeping source in /usr/src/ permanently. most programs you can simply remove by deleting the single executable it makes, but naturally some produce more than jsut one program. most source is fairly small however, <10mb decompressed. you can always just recompress the source and archive it tho. mind you my source compile of mozilla took up 1.2gb!
