pbuilder "permission denied" errors

[djsephiroth]

pbuilder asks for my sudo password, but fails with "permission denied" errors.

Example:

Is your makefile installing to / or to $DESTDIR?

Your makefile should look like this (please correct me!):



cp <stuff> $(DESTDIR)/etc/
cp <stuff> $(DESTDIR)/moreplaces

That way, if you're make-ing normally, it works normally, if you're running a deb package, it installs to where dh says, or where you say. :)

IDK if this helps, but that's what it looks like to me.

[djsephiroth]

That makes sense.

Do I need to prepend $(DESTDIR) to every instance of / in the Makefile?

[Bachstelze]

What does your Makefile look like?

From what I am seeing, it appears that the fake root is denied access to locations such as /etc in the pbuilder chroot. No idea why that would be though.

Using $(DESTDIR) in the copy operations caused the build process to attempt to place the files in, for example, /tmp/buildd/nameoftheprogram.1.2-3/etc/init.d/somedaemon (in the real fs, where "/tmp/buildd/nameoftheprogram.1.2-3" is the build dir) instead of /etc/init.d/somedaemon (in the chroot)

That's good, all pbuilder does is emulate the build machines to make sure you don't waste time yourself. It needs to have write permissions so it can build the deb.

Basically, preappend $DESTDIR to all instances of output files.

[djsephiroth]

With $(DESTDIR), I get "no such file/directory" errors instead of "permission denied" errors.

Weird. Build it locally before you build with pbuilder. You should end up with an entry in debian representing the file tree.

[djsephiroth]

Same "No such file or directory" errors when using dpkg-buildpackage locally instead of pbuilder.

If you're using cp (I think you're meant to use install, instead, but hey), I think a workaround would be to put a mkdir -p in front of every cp.

Or you could use debian/package.install and use dh_install.

[djsephiroth]

I may just cook up my own Makefile instead of using the one provided with the source. There were some other odd things aside from the "cp" commands.

[djsephiroth]

I resolved the issues by:


Replacing "cp" and "chmod" operations with "install"
Removing all "strip" operations
Prepending $(DESTDIR)$(PREFIX) to all instances of absolute paths

Good, good. Nice to hear you got it working, some of mine are a nightmare. Nice people like bachstelze and sevenmachines help though.

[djsephiroth]

Indeed, thanks for the assistance.
