I'd guess it's the same way as with LD_LIBRARY_PATH [0] but I'm not sure .You install scl-utils and meta-package (in my case we are using ruby 1.9.3 on el6 - it is named ruby193). And then: # ruby --version ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux] # scl enable ruby193 "ruby --version" ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux] "scl enable foo" will (beside few other things) the script /opt/rh/ruby193/enable which is very short and contains: export PATH=/opt/rh/ruby193/root/usr/bin:$PATH export LD_LIBRARY_PATH=/opt/rh/ruby193/root/usr/lib64:$LD_LIBRARY_PATH export MANPATH=/opt/rh/ruby193/root/usr/share/man:$MANPATH
Are these scripts generated by SCL or should I provide them ?
This allows you to install ruby193 packages into something which looks like chroot in /opt/rh/ruby193/root, but it actually is not chroot. It is just preferred path. And allows you to use libraries from base operating system.
Can the paths be customized ? E.G. removing the 'root' directory, or setting it to something else ?

Can this behavior be modified ? Can SCL modify my current shell ?
SCL allows you to easy convert your spec files to SCL spec files (man
spec2scl) with just very few changes. For example when you install
ruby193-build and scl-utils-build, then %{_bindir} is evaluated to:
/opt/rh/ruby193/root/usr/bin
I can do the same thing by modifying %_prefix in ~/.rpmrc , right ? ;) _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxxxxx http://lists.rpm.org/mailman/listinfo/rpm-list
