Using libraries in FFI

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 !

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

best,

hi,

shouldn’t there be quotes here like such:

LD_LIBRARY_PATH="$PLUGINS:$SVMLLP:${LD_LIBRARY_PATH}" exec "$BIN/squeak" "$@„
