Declaration is incompatible with "extern const ti_sysbios_knl_Semaphore_Handle task2"

On our C6678 evmboard, I use the mcsdk's project "client_c6678l" to build, everything ok.

But when I want to add the IPC module into the project, I meet a problem that says my Semaphore_Handle is incompatible in building. Our Bios version is 6.33.6.50, and XDCtools version is 3.23.4.60 and last the IPC module version is 1.24.3.32.

Without the IPC ,nothing is wrong. When I add and use the IPC module ,the problem occurs.

Finally I find the problem is caused by one Headfile "#include <xdc/cfg/global.h>" but I don't know why…

I guess maybe the IPC template's XDC has some difference with the MCSDK example's…
