Hello Julian,
this hack works excellently, and we've run the application under
valgrind successfully on Meizu M9 with Android 4.
Then, we tried the same on Motorola Razr with Android 2.3.6, but our
attempt to run the application under valgrind
failed very early.
The following message from logcat seems to distinguish those two cases:
dalvikvm: could not disable core file generation for pid 8403:
Operation not permitted
This does not happen on the other device. It seems that some access
permissions are insufficient, but I do not even know where to start.
I remember that in your README that describes Valgrind usage on Android
you mention insufficient privileges for temp directory. This
may be similar.
Or it may be case of a difference between Android 2.3 and Android 4.0.
Do you have any ideas?
Best regards
Marian
P.S.: In 10 days, we're going to have dedicated pandaboard for these
experiments, but so far we must limit ourselves to the normal devices.
