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.

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 ...

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 !
