[Scilab-users] Java base example can't find symbol from the libstdc++ library

[Keith Cummings]

Following the instructions found here 
(https://help.scilab.org/docs/5.5.1/en_US/compile_and_run_javasci_v2.html) 
doesn't work on my Linux Mint 17 machine.  Here are the commands I ran:

These three commands work as expected:
export SCI=/opt/scilab/scilab-5.5.1/share/scilab/
javac -cp 
$SCI/modules/javasci/jar/org.scilab.modules.javasci.jar:$SCI/modules/types/jar/org.scilab.modules.types.jar:. 
BasicExample.java
export 
LD_LIBRARY_PATH=/opt/scilab/scilab-5.5.1/lib/scilab/:/opt/scilab/scilab-5.5.1/lib/thirdparty/

This one fails with the following error message:
java -cp 
$SCI/modules/javasci/jar/org.scilab.modules.javasci.jar:$SCI/modules/types/jar/org.scilab.modules.types.jar:. 
BasicExample


The native library javasci does not exist or cannot be found.

The symbol _ZTVN10__cxxabiv120__si_class_type_infoE is defined in 
libstdc++, so I'm not sure why it is not being found there.
