Please post the gem install command and the exact response you get
back from it (using copy-paste).

I don’t use Linux a great deal, but I seem to recall that Debian-based
systems split the headers out into a different package. This could be
the
case here - try looking for a package called something like
libstdc++5-dev
and install it.

You must have libstdc++ installed.

thanks i will try it - am using 7.10 as it was the last stable release
for LinuxMCE.
the command returns libstdc++5-3.3-dev

installed.
thanks for help btw -this is really bothering me - i dont know what next
to try.

apt-cache shows what packages are available.
If you have it installed, then there is some other problem. Post your
mkmf.log which will show the actual compiler error.
This will probably be somewhere under
/var/lib/gems/1.8/gems/derailed-rhouse-*/ext/
Brian C. wrote:

That is, available to be installed.
dpkg-query -l | grep stdc
will show you if you have it installed.

there is not mkmf.log for derailed-rhouse … but there is for other
gems…
?
sorry i meant to say its installed but am still getting the same problem
as in ruby gems claims that it is not there.
HELP!

If you have libstdc++6, then you should be able to install
libstdc++6-4.2-dev (unless you got that libstdc++6 package from
somewhere outside the standard Ubuntu package respositories)
If you’re not getting a mkmf.log, then perhaps it’s failing building a
dependency. Look for the mkmf.log with the most recent timestamp

Did you try to create a symlink from libstdc++.so -> libstdc++.6.so (or
whatever your current version is named)?
Kind regards

Distributions should stop splitting up every package.
It confuses new users a lot, and they have to invest their time to
decripple packages again.
the mystery continues …

Package libstdc++6-4.1-dev is not available, but is referred to by
another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

http://linuxmce.com/index.php/download implies that 8.10 is the
latest… you are two versions behind,
Also you’ll need sudo apt-get install libstdc++6 libstdc++6-dev
(shouldn’t have to specify versions beyond the 6)
I meant to stay last stable non-beta. I’ve had many issues with 8.10
LinuxMCE, hence why I’ve reverted to 7.10.
I know its 2 versions behind, but it has a much better launch manager,
and setup wizard.
