I can successfully emerge swt-3.0-r2 and swt-3.1_pre2, but in the process it generates hundreds of warnings like this: warning: cast to pointer from integer of different size But when I try to run an SWT program (I've tried a simple SWT Hello World and Azureus), it always segfaults giving this stack trace: Stack: [0x00007fffffe00000,0x0000800000000000), sp=0x00007fffffffc668, free space=2033k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libc.so.6+0x6fb3b] Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) j org.eclipse.swt.internal.gtk.OS.memmove([BII)V+0 j org.eclipse.swt.internal.Converter.wcsToMbcs(Ljava/lang/String;[CZ)[B+68 j org.eclipse.swt.internal.Converter.wcsToMbcs(Ljava/lang/String;Ljava/lang/String;Z)[B+23 j org.eclipse.swt.widgets.Display.<clinit>()V+11 v ~StubRoutines::call_stub j SWTHello.main([Ljava/lang/String;)V+0 v ~StubRoutines::call_stub Reproducible: Always Steps to Reproduce: 1. emerge swt 2.

Here's the Hello World program I'm trying to run: import org.eclipse.swt.widgets.*; import org.eclipse.swt.*; public class SWTHello { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); Label label = new Label(shell, SWT.NONE); label.setText("Hello, World!"); shell.pack(); label.pack(); shell.open(); while(!shell.isDisposed()) if(!display.readAndDispatch()) display.sleep(); display.dispose(); label.dispose(); } }
I forgot to say I'm using sun-jdk-1.5. And just to make it clearer: it segfaults both with swt-3.0-r2 and swt-3.1_pre2.
I think I've made some progress: In the swt-3.1_pre2 ebuild, I've replaced the source download file "swt-3.1M2-linux-gtk.zip" with "swt-3.1M2-linux-gtk-amd64.zip". It emerges fine - and now, instead of hundreds of warnings, it only generates 2: cc -O -Wall -DSWT_VERSION=3106 -DLINUX -DGTK -I/opt/sun-jdk-1.5.0.02/include -I/opt/sun-jdk-1.5.0.02/include/linux -fpic -c callback.c callback.c: In function `Java_org_eclipse_swt_internal_Callback_bind': callback.c:211: warning: cast from pointer to integer of different size callback.c: In function `Java_org_eclipse_swt_internal_Callback_unbind': callback.c:229: warning: cast from pointer to integer of different size The problem is that it still segfaults, but now the stack trace is different: Stack: [0x00007fffffe00000,0x0000800000000000), sp=0x00007fffffffc8d0, free space=2034k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) V [libjvm.so+0x36347f] V [libjvm.so+0x37edc5] C [libswt-gtk-3106.so+0x2d365] Java_org_eclipse_swt_internal_Callback_bind+0x1ff j org.eclipse.swt.internal.Callback.<init>(Ljava/lang/Object;Ljava/lang/String;IZ)V+144 j org.eclipse.swt.internal.Callback.<init>(Ljava/lang/Object;Ljava/lang/String;I)V+5 j org.eclipse.swt.widgets.Display.createDisplay(Lorg/eclipse/swt/graphics/DeviceData;)V+191 j org.eclipse.swt.widgets.Display.create(Lorg/eclipse/swt/graphics/DeviceData;)V+17 j org.eclipse.swt.graphics.Device.<init>(Lorg/eclipse/swt/graphics/DeviceData;)V+135 j org.eclipse.swt.widgets.Display.<init>(Lorg/eclipse/swt/graphics/DeviceData;)V+2 j org.eclipse.swt.widgets.Display.<init>()V+2 j SWTHello.main([Ljava/lang/String;)V+4 v ~StubRoutines::call_stub V [libjvm.so+0x362835] V [libjvm.so+0x4faca9] V [libjvm.so+0x362645] V [libjvm.so+0x3854e5] V [libjvm.so+0x37a81e] C [java+0x1f41] strcmp+0x779 Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) j org.eclipse.swt.internal.Callback.bind(Lorg/eclipse/swt/internal/Callback;)J+0 j org.eclipse.swt.internal.Callback.<init>(Ljava/lang/Object;Ljava/lang/String;IZ)V+144 j org.eclipse.swt.internal.Callback.<init>(Ljava/lang/Object;Ljava/lang/String;I)V+5 j org.eclipse.swt.widgets.Display.createDisplay(Lorg/eclipse/swt/graphics/DeviceData;)V+191 j org.eclipse.swt.widgets.Display.create(Lorg/eclipse/swt/graphics/DeviceData;)V+17 j org.eclipse.swt.graphics.Device.<init>(Lorg/eclipse/swt/graphics/DeviceData;)V+135 j org.eclipse.swt.widgets.Display.<init>(Lorg/eclipse/swt/graphics/DeviceData;)V+2 j org.eclipse.swt.widgets.Display.<init>()V+2 j SWTHello.main([Ljava/lang/String;)V+4 v ~StubRoutines::call_stub Notice that the warnings were in callback.c, in function `Java_org_eclipse_swt_internal_Callback_bind', and that this function also appears in the stack trace. Maybe it's related?
Ok, I found the problems: 1. The download link was incorrect - it must be swt-xxx-linux-gtk-x86_64.zip (or -gtk-amd64.zip for older versions) for amd64. 2. SWT must be compiled with -DSWT_PTR_SIZE_64 I've created an ebuild based on swt-3.1_pre2.ebuild for the latest SWT (3.1M5a) which incorporates both fixes. It finally works now, so please update it in portage :)
Created attachment 57959 [details] swt-3.1_pre5.ebuild Fixed ebuild, now works on amd64.
thanks a lot for reporting and for solving the problem on your own. i've backported the fixes also to the 3.1_pre2 ebuild. fixed in cvs
