SVN *** EXTREMELY DANGEROUS ***

I'd like to warn everybody who is installing the SVN version of CodeLite.
Here my sad history:
I have access to a directory, say /courses/CPP, on a file server of a students' computer lab.
I've installed SVN-CodeLite yesterday with
./configure --prefix=/courses/CPP --plugins-dir=/courses/CPP
make
make -n install (checking it)
make install
Everythings went well (as expected)
Because of missing features due to an old version of wxWidgets, I installed a newer version of wxWidgets
today.
Then again
./configure --prefix=/courses/CPP --plugins-dir=/courses/CPP
make clean
make
make -n install (checking it, but not enough)
make install
now I got the message
uninstalling old version (or similar)
and the whole directory /courses/CPP got nuked.
Fortunately, I lost only a few hours of work, since there is a nightly backup.
But it could have been much worse.
I don't complain since I should have looked more closely to the output of
make -n install
but it's a hard punishment for such a carelessness.
Helmut.

this happened because of the wrong plugins-dir you entered. there aren't rm -rf lines generated for prefix-pwd but for plugins-dir.. i'm not even sure whether plugins would work if they aren't in the codelite-dir (they are in /usr/lib/codelite by default).
why are you installing it to a non-standard directory anyway?

I've found the culprit:
Code: Select all
./configure --prefix=/courses/CPP --plugins-dir=/courses/CPP
installs into /courses/CPP instead of /courses/CPP/lib/codelite and similar.
Now an uninstall is asking for hell.
But
works just fine.
This is very irritating,
Helmut.

it's not irritating. maybe my post was a bit unspecific.
if you hand in a custom plugin-dir the default setting gets overridden (thus deleting your custom directory on uninstall). the new makefile (trunk rev) checks for whether plugins-dir is set to /usr/lib and prevents removing it now.
plugins however should be placed in a separate directory like the codelite-directory, for example /usr/lib/codelite, since they get removed completely on uninstall (plugins dir gets deleted recursively) so in your case --plugins-dir=/Course/CPP/lib/codelite would probably have been correct.
it is unnecessary to set this anyway, since the pluginsdir gets auto-set to $prefixdir/lib/codelite (that's why it worked without setting the pluginsdir separately).
so for the record:
prefix (default) = /usr
plugins-dir (default) = $prefix/lib/codelite
and each one gets overriden by the respective userswitch

Hi,
perhaps the notion "prefix" has trapped me. If I say --prefix=/usr/local I don't expect the package to install something
directly into /usr/local but in some subdirectory.
So, I was expecting CodeLite would install into something like
<PREFIX>/lib/codelite or <PREFIX>/share/codelite
At least, that would cause much less harm if someone misinterprets is like me.
Regards,
Helmut.

Hi Helmut,
Just to mention that, in the current svn version, your problem wouldn't have happened. It's now not necessary to specify --plugins-dir at all (though you can if you really want to). If you provide a --prefix, plugins-dir now defaults <prefix>/lib/codelite.
However, I'm not sure how you managed to lose user data, unless you were storing it in the same dir to which you installed CodeLite. I'd suggest that wouldn't be a good place to put it anyway.
Regards,
David

Suggest the title of this thread be renamed: SVN: A warning if using --prefix
