Bug in convertStruct for C++ class. #103

Open BaconDave opened 8 years ago

BaconDave commented 8 years ago

Hi, First of all great work on Bridj, Jnaerator and JavaCl! I think I've might have stumbled on a small bug in Jnaerator, running from the maven plugin.

Input header file:

ifndef TEST_HPP

define TEST_HPP

namespace testns { class TestClass { public: TestClass(); explicit TestClass(unsigned int* seed); }; }

endif

When run with this small test sample above it hangs with this stack trace:

java.lang.NullPointerException at com.ochafik.lang.jnaerator.BridJDeclarationsConverter.convertStruct(BridJDeclarationsConverter.java:633) at com.ochafik.lang.jnaerator.DeclarationsConverter.outputConvertedStruct(DeclarationsConverter.java:635) at com.ochafik.lang.jnaerator.DeclarationsConverter.convertStructs(DeclarationsConverter.java:688) at com.ochafik.lang.jnaerator.DeclarationsConverter.fillLibraryMapping(DeclarationsConverter.java:909) at com.ochafik.lang.jnaerator.BridJDeclarationsConverter.fillLibraryMapping(BridJDeclarationsConverter.java:946) at com.ochafik.lang.jnaerator.BridJDeclarationsConverter.generateLibraryFiles(BridJDeclarationsConverter.java:1020) at com.ochafik.lang.jnaerator.JNAerator.generateLibraryFiles(JNAerator.java:1493) at com.ochafik.lang.jnaerator.JNAerator.jnaerationCore(JNAerator.java:1465) at com.ochafik.lang.jnaerator.JNAerator.jnaerate(JNAerator.java:1018) at com.ochafik.lang.jnaerator.JNAerator$1.finished(JNAerator.java:786) at com.ochafik.lang.jnaerator.JNAeratorCommandLineArgs$ArgsParser.parse(JNAeratorCommandLineArgs.java:162) at com.ochafik.lang.jnaerator.JNAerator.main(JNAerator.java:791) at com.ochafik.lang.jnaerator.JNAerator.main(JNAerator.java:203) at com.jnaerator.JNAeratorMojo.execute(JNAeratorMojo.java:110) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:84) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:59) at org.apache.maven.lifecycle.internal.LifecycleStarter.singleThreadedBuild(LifecycleStarter.java:183) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:161) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:537) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:196) at org.apache.maven.cli.MavenCli.main(MavenCli.java:141) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:290) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:230) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:409) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:352)

If the constructor with parameter is removed it works again.
