Hello,
osmo-trx-lms: Threads.cpp:133:
void Thread::start(void* (*)(void*), void*): Assertion `!res' failed.
[...]
Can someone provide me a little light on this?
As far as I can see, pthread_attr_setstacksize() fails to set
required stack size for a thread. Probably, the amount of RAM
is not enough. But in general, this part of code looks dirty:
/** A C++ wrapper for pthread threads. */
class Thread {
/* ... */
// FIXME -- Can this be reduced now?
size_t mStackSize;
/* ... */
/** Create a thread in a non-running state. */
Thread(size_t wStackSize = (65536*4)):mThread((pthread_t)0) {
pthread_attr_init(&mAttrib); // (pat) moved this here.
mStackSize=wStackSize;
}
/* ... */
I am now wondering, where does this magic 65536*4 comes from,
and how can we estimate and adjust this properly?
With best regards,
Vadim Yanitskiy.
