Hello,
I want to dynamically Create a SYS/bios mailbox ，but I encounter a problem.The complete codes is as follows:

if (events & Event_Id_00) {
/* Get the posted message.

I rewrite mmw_dss.c based on mmw_caputre demo.there is a error when compile. the errors as follows:
Undefined reference to 'ti_sysbios_knl_Mailbox_Params__init__S' in file ./dss_main.oe674 .xdchelp /mmw_dss C/C++ Problem
Undefined reference to 'ti_sysbios_knl_Mailbox_pend__E' in file ./dss_main.oe674 .xdchelp /mmw_dss C/C++ Problem
Undefined reference to 'ti_sysbios_knl_Mailbox_post__E' in file ./dss_main.oe674 .xdchelp /mmw_dss C/C++ Problem
when I add the content （var Mailbox = xdc.useModule('ti.sysbios.knl.Mailbox');） to the dss_mmw.cfg file，the project compile successfully.When debugging ,it encounters the problems as follows:
[C674X_0] The myEvent set up successful!
{module#35}: line 78: error {id:0x10000, args:[0x804a1d, 0x804a1c]}
xdc.runtime.Error.raise: terminating execution
can you help me,thanks very much!
