Re: [Plib-users] Undefined reference to ...

[Ibrahim M. <ib...@ya...>]

Hi again,

After trying a few things, I thought of trying to build plib from source. So I do an apt-get
source, and try to build the .deb file. It told me that I needed xlibmesa-glu-dev. So I apt-got it
too. But why was this dependency issue brought up when building from source but wasn't with a
regular apt-get plib1.7-dev? Oh well... So now that plib was installed, I tried to recompile the
examples. I am still getting errors. But these are way different. Can you help me figure out what
is going on?

Here is the output:

-------------------------------------------

Could it be that I have quite a few gcc's and two g++'s installed?
Here is a little test I did:

debian:~# dpkg --get-selections | grep gcc
gcc                                             install
gcc-2.95                                        install
gcc-3.0                                         install
gcc-3.0-base                                    install
gcc-3.3-base                                    install
libgcc1                                         install
debian:~# dpkg --get-selections | grep g++
g++                                             install
g++-2.95                                        install

I will hit google and see what I can figure out.

Thank you,
Ib
