Embedding simulation kernel containing activity() module.

[Isaac Abhilash]

Hi,

I am trying to embed the simulation kernel to run from a c++ application. I followed the samples embedding and embedding2, but when I run my program I get the following error from the debugger :

Program received signal SIGSEGV, Segmentation fault.
swapcontext () at ../sysdeps/unix/sysv/linux/x86_64/swapcontext.S:40
40    ../sysdeps/unix/sysv/linux/x86_64/swapcontext.S: No such file or directory.
(gdb) bt

#5  0x0000000000409206 in main () at main.cc:277

Error is pointing to the swapcontext. So I am guessing this is due the use of activity() module in my program.

Has anyone tried using activity() with embedding? Is it a limitation of the embedding / is there anything wrong with my configuration? If I try any other samples that use handleMessage() there is no error. I tried using the hypercube sample ( which uses activity() ) and it also fails.

Could anyone please help me in this regard.

Thanks,
Isaac
