How to use fake root to build packages

[ajaykumar.mysore]

Hi,
Our sir told me to use the fake root for doing packages instead of getting logged in as root. But can any one guide me how to use fake root ?

I just learned about this also from the other thread. I figured out how to use fakeroot by reading the man page (man fakeroot). Here's how I do it.
fakeroot slkbuild
If you don't use slkbuild, then just insert the build script file name instead.
You might also want to consider Shador's method

I do:
alias build="fakeroot slkbuild -X"

I just inserted this line my users ~.bashrc file.

I am using a build script from zenwalk with handles with the binaries release of apache-ant.
fakeroot seemes not to work here with makepkg and other stuff ...

$ fakeroot ./build-ant.sh
(...)
ln: Erzeuge symbolische Verknüpfung „./WHATSNEW“: Keine Berechtigung
cp: reguläre Datei „/tmp/package-ant/usr/src/ant-1.7.1/build-ant.sh“ kann nicht angelegt werden: Keine Berechtigung
./build-ant.sh: line 105: /tmp/package-ant/install/slack-desc: Keine Berechtigung
./build-ant.sh: line 131: /tmp/package-ant/install/doinst.sh: Keine Berechtigung
./build-ant.sh: line 151: makepkg: command not found

This sounds like your user hadn't access to /tmp. Is that possible?
The problem with makepkg is that many packagers just invoke 'makepkg' relying on PATH. But fakeroot doesn't touch PATH (i.e. it's still a user's PATH), so to make it work you just have to replace it with '/sbin/makepkg'

Nope.

$ ls -ld /tmp/
drwxrwxrwt 11 root root 420 2010-01-01 15:18 /tmp/
$ mount |grep tmp
tmpfs on /dev/shm type tmpfs (rw)
none on /tmp type tmpfs (rw)

Done. But /tmp problem still exists.

I don't know what the script is trying to do at those lines, but it definitely is some kind of permission problem.
touch /tmp/somefile works too?

[damNageHack]

Code: Select all

fakeroot touch /tmp/bla

Just works.

Yes. On the other machine, it works perfectly. So I assume a configuration problem caused by the user (me in this case ).

No problem.
