Linker errors lazarus / 1-Linux ---------------------------------------------------------------------- segfault · 2017-05-22 16:29 Hi, I'm using FP 3.0.2 on a Linux 32 bit system (Debian based distro) and am getting errors when trying to compile a program which calls the ptcgraph unit, which I found out about on the Wiki (http://wiki.freepascal.org/ptc). They are: /usr/bin/ld: cannot find -lXxf86vm /usr/bin/ld: cannot find -lXxf86dga I'm pretty new to Linux but assume these are telling me that I'm missing some libraries. I know how to use apt-get but what are the exact names of the libraries? Google hasn't been much help. Thanks in advance for any help and sorry for being such a noob. ---------------------------------------------------------------------- Handoko · 2017-05-22 16:46 For Linux users, I suggest you to use Synaptic Package Manager. It will help you search and install libraries easily. I checked my Ubuntu Mate using Synaptic and I found I have these installed (by default): - libxxf86vm-dev - libxxf86vm1 - libxxf86vm1: 386 ---------------------------------------------------------------------- segfault · 2017-05-22 16:50 Hi Handoko, Many thanks, problem solved. ---------------------------------------------------------------------- Handoko · 2017-05-22 16:56 Glad to hear it is solved.
