problem during using irq_plug()

I am new and I am testing the code from spru433j with CCS 4.2.3

IRQ_setVecs (0x100);
IRQ_plug(IRQ_EVT_TINT0, &myIsr);
IRQ_enable(IRQ_EVT_TINT0);
IRQ_globalEnable();

and I have defined the symbols _IRQ_plug, _IRQ_setVecs, _IRQ_globalEnable and _IRQ_enable.

But the compiler reported that ""D:/Program Files/Texas Instruments/ccsv4/tools/compiler/c5500/inclu

de/csl_irq.h", line 168: error: expected an identifier"

line 168 states that"CSLAPI CSLInt _IRQ_plug(Uint16 EventId, IRQ_IsrPtr funcAddr);"

Can anyone help me?

Thanks!

Most likely, one of the identifiers in the offending line is defined in one of your header files with a #define preprocessing directive in an unintended way. Please run the preprocessor on your input file and inspect the declaration of _IRQ_plug. (see http://processors.wiki.ti.com/index.php/Preprocess_Complex_Source_Code_for_Bug_Submissions) The less likely possibility is that the source code which immediately precedes the delcaration of _IRQ_plug has some sort of syntax error which doesn't get detected until you reach the next line.

Some additional tips to consider ...

Build with --verbose_diagnostics to get a better idea of what the compiler is complaining about. My guess is you have not configured things correctly for CSL. You are missing some -D symbol that is expected in the compiler build command, or something like that.

Thanks and regards,
