Java wrapper build error

[espositomarco]

OS: Debian "bullseye" Nomad version: 4.2

When building the Java wrapper, following the instructions in interfaces/jNomad/Readme, I get the following error:

[ 93%] Built target jNomad
[ 93%] Linking CXX executable NMOpt.exe
Scanning dependencies of target jNomad_jar
gmake[2]: *** No rule to make target 'interfaces/jNomad/SWIGTYPE_p_NOMAD_4_1__EvalParameters.java', needed by 'interfaces/jNomad/CMakeFiles/jNomad_jar.dir/java_compiled_jNomad_jar'.  Stop.
gmake[1]: *** [CMakeFiles/Makefile2:1366: interfaces/jNomad/CMakeFiles/jNomad_jar.dir/all] Error 2
gmake[1]: *** Waiting for unfinished jobs....

and cmake exits with error code 2.

Here is the complete Dockerfile I'm using:

FROM openjdk:8u332-bullseye

ENV DEBIAN_FRONTEND=noninteractive

ENV NOMAD_HOME="/NOMAD42"
WORKDIR /NOMAD42

    cmake --build build/release --parallel 16 && \
    cmake --install build/release

ENV LD_LIBRARY_PATH="/NOMAD42/build/release/lib"

WORKDIR /
CMD /bin/bash

I was able to build the C and Python interfaces without a problem.

Any help would be greatly appreciated!

I will look into that soon. Thanks for reporting this issue.

I have made a few changes to prevent this bug. These changes are available in the master and develop branches. Right now it is NOT available in the Nomad tar.gz.

Mostly, I added a directive to build EvalParameters.java and define a class for EvalParameters in jNomad.i. (in directory interfaces/jNomad). I also replaced a hardcoded template name used in jNomad CMakeLists.txt. I have added a CMake variable NOMAD_SRC_TEMPLATE in the root CMakeLists.txt.

I just tried building the master branch with the Java interface and I got the exact same error as before. I even tried to modify the interfaces/jNomad/CMakeFiles.txt file and use the new variable you created, but I still get the same "no rule to make..." error.

I'm using the same Dockerfile as before, I just replaced the .tar.gz download with the git clone.

I will look into that as soon as possible.

This target 'interfaces/jNomad/SWIGTYPE_p_NOMAD_4_1__EvalParameters.java' is not really needed (and NOMAD_4_1 is the wrong version).

I have fixed this in Develop and Master branches. It will available in next tagged version 4.3.
