Ok.

gdb just gave me a hint.

Then, I did;

$ ldd /usr/bin/scilab-bin | grep not

        libsciscinotes.so.5 => /usr/lib64/scilab/libsciscinotes.so.5 (0x00007f4af6aae000)
        libsciscinotes-disable.so.5 => /usr/lib64/scilab/libsciscinotes-disable.so.5 (0x00007f4af25bd000)
        libjava.so => not found
        libverify.so => not found
        libjvm.so => not found
        libjava.so => not found
        libverify.so => not found
        libjvm.so => not found
        libjava.so => not found
        libverify.so => not found
        libjvm.so => not found
        libjava.so => not found
        libverify.so => not found
        libjvm.so => not found

Why not found?

What is the correct environment?

$ echo $JAVA_HOME
/usr/lib64/jvm/java

$echo $JRE_HOME
/usr/lib64/jvm/java/jre

Are these insufficient?

But, after configure, in the resulted Makefile

[...]
JAVA_JNI_INCLUDE = -I/usr/lib64/jvm/java/include -I/usr/lib64/jvm/java/include/linux
JAVA_JNI_LIBS = -L/usr/lib64/jvm/java/jre/lib/amd64 -ljava -lverify -L/usr/lib64/jvm/java/jre/lib/amd64/server -ljvm
[...]

These are entirely correct.
But, compilation didn't include them.

Why?

Regards,
