[tracecompass-dev] Reading MIPS traces
|
Hi,
I'm trying to use the Linux Tools Trace Viewer (i.e. Trace Compass
outside of Eclipse, if I understand it correctly) to read some traces
created by LTTNG on a MIPS (big endian) architecture.
However, upon clicking on the trace file in order to show it, I get this
message:
Exception in thread "Thread-35" java.lang.NullPointerException

org.eclipse.linuxtools.tmf.ctf.core.CtfTraceManager.getIterator(CtfIteratorManager.java:169)

The same test run on an ARM (little endian) platform seems to work fine
though. As I remember there've been endianness issues in the past, and I
assume most tests are run on x86 platform (hence little endian), could
it be possible that we're hitting the same issue again?
Please find attached a test case where I could get the above error.
If it makes any difference, the daily build I used is
linuxtools-trace-viewer-1.1.0-20141203-0203-linux.gtk.x86_64.tar.gz.
Could anyone please help me with this issue?
Thank you!
