Hi Eliot, My problem is not with the VM, my problem is with my own library that I connect to through FFI. I know where the libraries are ! I have tried to add them in /etc/ld.so.conf.d , that does not work. I have tried export LD_LIBRARY_PATH, but somehow it erases some libraries needed by pharo. I have done sudo ldconfig ... In fact I have one library that depends from another one. In FFI I call one method which calls another method in the other library. I have tried to create symbolics links in the directory ⦠I have checked that nm gives the right symbol with the right type .. So I have no idea what to try now !

Hi Annick,
LD_LIBRARY_PATH should be set to point to the relevant directories, but this can be tricky as there is a lot if variation across Linux distros as to where libraries are kept. The squeak script that comes with the Cog VMs extends LD_LIBRARY_PATH, so if you know where your libraries are you can use the script to find the other libraries the VM needs (c library and plugins).

Hi,
I am using a module in FFI which depends on a large library letâs say 10 dynamic .so files in a directory. How is it possible to use this library without making all symbolic links ?

Try to run pharo with strace. That way you will see all syscalls including libraries opens that pharo does attempt. That's what I do when trying to figure out such things. HTH Phil On Wed, Oct 22, 2014 at 2:45 PM, Annick Fron <list@afceurope.com> wrote:

But if you use the script I include with my VMs it won't erase. It extends LD_LIBRARY_PATH. Find an example attached.

Here's the operative line (the last one). PLUGINS is the directory containing VM plugins, SVMLLP is "Smalltalk VM LD_LIBRARY_PATH" and specifies the directories containing the C libraries the VM depends on (C library, libuuid, etc). LD_LIBRARY_PATH=$PLUGINS:$SVMLLP:${LD_LIBRARY_PATH} exec "$BIN/squeak" "$@"
I have done sudo ldconfig ...
