resolving anonymous struct in C library

[seem-less]

I am trying to build a javacpp-preset for the Leap Motion controller in Windows. I am getting a compiler issue for the following snippet of code found in the LeapC.h header file. Header and library files can be found by downloading the Windows SDK here .

Snippet from C Header file:

typedef struct _LEAP_DISTORTION_MATRIX {
  /** A point in the distortion grid. @since 3.0.0 */
  struct {
    /** The x-pixel coordinate. @since 3.0.0 */
    float x;
    /** The y-pixel coordinate. @since 3.0.0 */
    float y;
  }
  /** A grid of 2D points. @since 3.0.0 */
  matrix[LEAP_DISTORTION_MATRIX_N][LEAP_DISTORTION_MATRIX_N];
} LEAP_DISTORTION_MATRIX;

this is the current state of the presets/leapmotion.java file:

package org.bytedeco.leapmotion.presets;

import org.bytedeco.javacpp.*;
import org.bytedeco.javacpp.annotation.*;
import org.bytedeco.javacpp.tools.*;

@Properties(
    value = {
        @Platform(
                value = "windows",
                include = "LeapC.h",
                link = "LeapC")
    },
    target = "org.bytedeco.leapmotion",
    global = "org.bytedeco.leapmotion.global.leapmotion"
)
public class leapmotion implements InfoMapper {
    static { Loader.checkVersion("org.bytedeco", "leapmotion"); }

    public void map(InfoMap infoMap) {

        infoMap.put(new Info("LEAP_EXPORT","LEAP_CALL","LEAP_STATIC_ASSERT","static_assert").cppTypes().annotations())
                
                .put(new Info("_LEAP_CONNECTION").pointerTypes("LEAP_CONNECTION"))

                .put(new Info("LEAP_CLOCK_REBASER").valueTypes("LEAP_CLOCK_REBASER").pointerTypes("@Cast(\"LEAP_CLOCK_REBASER*\") _LEAP_CLOCK_REBASER", "@ByPtrPtr LEAP_CLOCK_REBASER"))

                .put(new Info("_LEAP_RECORDING").pointerTypes("LEAP_RECORDING"))
                .put(new Info("LEAP_RECORDING").valueTypes("LEAP_RECORDING").pointerTypes("@Cast(\"LEAP_RECORDING*\") _LEAP_RECORDING", "@ByPtrPtr LEAP_RECORDING"))

                .put(new Info("_LEAP_CALIBRATION").pointerTypes("LEAP_CALIBRATION"))
                .put(new Info("LEAP_CALIBRATION").valueTypes("LEAP_CALIBRATION").pointerTypes("@Cast(\"LEAP_CALIBRATION*\") _LEAP_CALIBRATION", "@ByPtrPtr LEAP_CALIBRATION"));
         
    }
}

The compiler error:

How do I handle this struct that has a nested struct in it? (I believe it is an anonymous struct too)

Thanks!

[saudet]

Fixed in commit 04da8eb. Thank you for reporting!
Please give it a try with the snapshots: http://bytedeco.org/builds/

[seem-less]

I pulled from bytedeco/javacpp and successfully re-installed using mvn clean install -Djavacpp.platform=windows-x86_64. I then went back into the javacpp-presets directory and successfully ran mvn clean install -Djavacpp.platform=windows-x86_64 --projects .. I then got the same compiler error as described in the original post after running mvn clean install --projects .,leapmotion.

All the code for creating this preset is in this PR for javacpp-presets. Am I doing something wrong in the preset file or is there still a bug?

[saudet]

You're probably getting another error. Please attach the whole log here.

[seem-less]

Here is the full log

[saudet]

You're not using the most recent version. If you have problems installing this locally, please use the snapshots instead: http://bytedeco.org/builds/

[seem-less]

I believe I am using the snapshots as seen in the PR on line 9 of the pom.xml

[saudet]

Make sure to run with mvn -U ... and if that doesn't work either, remove your local ~/.m2 cache, and try again. BTW, I'm not here to teach you how to use Maven! If you do not understand all this, please go read tutorials about it.

ok I used the -U flag to update snapshots and that didn't work. I deleted the ~/.m2 cache and tried again and that didn't work. I also used mvn dependency:purge-local-repository on both the javacpp and javacpp-presets folders, successfully re-built javacpp-1.5.6-SNAPSHOT.jar and javacpp-1.5.6-SNAPSHOT-windows-x86_64.jar and then tried installing leapmotion again by running mvn -U clean install --projects .,leapmotion and I am left with the same compiler error.

[saudet]

Well, what you have provided me with works perfectly fine for me on my end now. I cannot fix what isn't broken! Please provide me with maybe something else that doesn't work for you, and if it also doesn't work for me, then I'll be able to do something about it.

[saudet]

BTW, I don't see where the _LEAP_DISTORTION_MATRIX.java file gets generated. If you do not need it, please remove it.

[saudet]

Fix included in JavaCPP 1.5.6! Thanks for reporting, and I'm assuming it's also now working for you, but please let me know if you still have problems.
