Hello,
i just spent the last 20 hours with trying to compile javax.usb :D
well as far as i came i have compiled the API and the common RI without any
problems. now comes the part thats giving me the headache:
After the first errors i had to change the path to usb.h from <linux/usb.h>
to <usb.h> in the JavaxUsbKernel.h, which made possible to sucessfully build
the ri-linux, but with a lot of warnings. the output was huge, so i post the
snippets that might be interesting:
[echo] Compiling class files.
[javac] Compiling 17 source files to
/home/d53r3/javaxusb/javax-usb-ri-linux/src
[javac] Note: Some input files use unchecked or unsafe operations.
[javac] Note: Recompile with -Xlint:unchecked for details.
[echo] Compiling JNI library.

JavaxUsbTopologyUpdater.c
[exec] JavaxUsbTopologyUpdater.c: In function
'Java_com_ibm_jusb_os_linux_JavaxUsb_nativeTopologyUpdater':

[exec] JavaxUsbTopologyUpdater.c:86: warning: passing argument 2 of

i get the "passing argument 2 warning" when compiling:
JavaxUsbTopologyUpdater.c
JavaxUsbTopologyListener.c
JavaxUsbActive.c
JavaxUsbPipeRequest.c
JavaxUsbInterfaceRequest.c
JavaxUsbControlRequest.c
JavaxUsbBulkRequest.c
JavaxUsbInterruptRequest.c
JavaxUsbIsochronousRequest.c
JavaxUsbError.c
i have uploaded the entire output here:
http://bm-mrs.servebeer.com/ant_output.txt
so, after adding all 3 jars and the javax.usb.properties directory to my
CLASSPATH environment variable and copying the .so file to my /usr/lib/
directory i get this when i try to build theDefaultControlPipe example
program:
----------
1. ERROR in DefaultControlPipe.java (at line 12)
import javax.usb.*;
^^^^^^^^^
The import javax.usb cannot be resolved
----------
2. ERROR in DefaultControlPipe.java (at line 13)
import javax.usb.util.*;
^^^^^^^^^
The import javax.usb cannot be resolved
----------
3. ERROR in DefaultControlPipe.java (at line 26)
UsbHub virtualRootUsbHub = ShowTopology.getVirtualRootUsbHub();
^^^^^^
UsbHub cannot be resolved to a type
----------
4. ERROR in DefaultControlPipe.java (at line 26)
UsbHub virtualRootUsbHub = ShowTopology.getVirtualRootUsbHub();
^^^^^^^^^^^^
and so on. it cant resolve anything from the javax.usb package, it does the
same wether the jars are in the CLASSPATH env variable or not.
Tried to but the jars and javax.usb.properties in the jre/lib/ext/ folder.
reducing the errors to 3:
----------
1. ERROR in DefaultControlPipe.java (at line 26)
UsbHub virtualRootUsbHub = ShowTopology.getVirtualRootUsbHub();
^^^^^^^^^^^^
ShowTopology cannot be resolved
----------
2. ERROR in DefaultControlPipe.java (at line 27)
List allUsbDevices = FindUsbDevice.getAllUsbDevices
(virtualRootUsbHub);
^^^^^^^^^^^^^
FindUsbDevice cannot be resolved
----------
3. ERROR in DefaultControlPipe.java (at line 28)
List usbHubs =
FindUsbDevice.getUsbDevicesWithDeviceClass(virtualRootUsbHub,
UsbConst.HUB_CLASSCODE);
^^^^^^^^^^^^^
FindUsbDevice cannot be resolved
----------
3 problems (3 errors)
Please help me and many thanks in advice :)
