    Default Where can I get the dlopen ? (unable to find the dlopen() function)

    Hi
    I had libsass, nodejs, etc, up and running in 13.2, and I've installed with no issues at all, following the instructions how to install libsass.
    However, I already had a lot of stuff installed in the system, and probably one of those packages had install this lib.

    But now, I'm lost.
    Trying to compile the libsass , upon .configure, I get this error:

    Code:
    checking for shl_load... no
    checking for shl_load in -ldld... no
    checking for dlopen... no
    checking for dlopen in -ldl... yes

    checking for library containing dlopen... no
    configure: error: unable to find the dlopen() function
    Not sure, what I have to install... the devels of gcc ?

    Thanks

    It's in glibc, in particular you need to have glibc-devel installed...

    I just install the libconfig++-devel , and libconfig++9 , but nothing yet.

    Hi
    Why not follow the spec file 'BuildRequires' on what's used and also the configure options...
    https://build.opensuse.org/package/v....spec?expand=1

    Or just use the rpm....

    ok, that's interesting. Is it going to get the latest version of libsass ? , Or one must edit that file to change the version ?

    Hi
    If 0.13.1 is the latest version, then yes, else just wait for it to get pushed to Tumbleweed?

    As Malcolm suggests, it's available as a pre-built package at the following link. If it's not the latest, you can submit a request to re-build through https://bugzilla.opensuse.org.

    https://software.opensuse.org/package/libsass

    If you still wish to compile from source and can't find a dependency, you can post a question about that particular file you can't locate...

    I'll repost here what I posted to your other thread about libsass...

    Reading up a bit on what libsass is, it appears that originally it was written in Ruby, but people thought so much of it that it was ported to C/C++ as "libsass" so that it could be wrapped for use in other languages.

    This suggests that although you'd probably still need to compile on your own for latest features and functionality (as of today, latest git contrib was 2 mths ago), you'd likely be able to get a "wrapped" libsass ready to go for the specific language you are developing in. If openSUSE isn't providing latest, there is a pretty good likelihood it's already available in the official repos for whatever language you are using (ie python = pip, ruby = gem, node = npm, etc). If you want to explore the official repos for your language, I've done some writeups how to setup for Ruby and Nodejs at the following wiki pages. A similar approach should be implemented for python using virtualenv.

    https://en.opensuse.org/User:Tsu2/nodejs

    Thanks all
    After all, I was missing the c++ from the gcc-c++ package.
    I thought glib was enough, but no. So I've installed that, and gcc-c++5 and gcc-c++48 just in case
    Don't know the difference between then, or witch package is supplying the dlopen() function, but I got this working, so it's ok !

    Thanks
