Patch matlab java

matlab_java_patch.sh

echo "Patching java... ($MATLAB_PATH/sys/java/jre/glnxa64/jre/bin/java)"
chmod u+rw "$MATLAB_PATH/sys/java/jre/glnxa64/jre/bin/java"
patchelf --interpreter "$(cat $NIX_CC/nix-support/dynamic-linker)" \
  --set-rpath "$libPath:$(patchelf --print-rpath $MATLAB_PATH/sys/java/jre/glnxa64/jre/bin/java)"\
  --force-rpath "$MATLAB_PATH/sys/java/jre/glnxa64/jre/bin/java"

Still get this error:

[nix-shell:~]$ /opt/MATLAB/R2017a/sys/java/jre/glnxa64/jre/bin/java
bash: /opt/MATLAB/R2017a/sys/java/jre/glnxa64/jre/bin/java: cannot execute binary file: Exec format error

readelf seems to indicate it is 64bit, which would match the matlab install type:

[nix-shell:~]$ readelf -h /opt/MATLAB/R2017a/sys/java/jre/glnxa64/jre/bin/java
