    Hi, I’ve tried to compile example code copy from PVRScope user manual, the code listed below:

    #include "PVRScope.h"

    int main(void)
    // Create the PVRScope data storage area
    SPVRScopeImplData* scopeData;
    // Initialise PVRScope
    const EPVRScopeInitCode returnCode = PVRScopeInitialise(scopeData);
    // Check initialisation succeeded
    if(returnCode != ePVRScopeInitCodeOk)
    // Handle the error
    // Create an array of counter definitions
    unsigned int numCounters = 0;
    SPVRScopeCounterDef *counterArray = 0;
    // Create the data structure to contain the counter readings
    SPVRScopeCounterReading counterReadings;
    // Continue initialisation
    PVRScopeGetCounters(scopeData, &numCounters, &counterArray, &counterReadings);

    // Select the desired counter group (3 in this instance)
    unsigned int desiredGroup = 3;
    // Store which group is currently active
    unsigned int activeGroup = 0;
    // Do a quick check to save some processing
    if(desiredGroup == activeGroup)
    desiredGroup = 0xffffffff;
    // Update the counters and store the active group
    if(PVRScopeReadCountersThenSetGroup(scopeData, &counterReadings, desiredGroup))
    activeGroup = counterReadings.nReadingActiveGroup;
    // Read the counters from the above group, and process them accordingly.
    // The counters will match (in order) the elements in ‘counterArray’ whose group
    // matches ‘counterReadings.nReadingActiveGroup’

    // De-initialise PVRScope
    PVRScopeDeInitialise(&scopeData, &counterArray, &counterReadings);

    return 0;

    then i compile it:
    gcc pvrtest.c
    A lot of errors were printed:
    In file included from pvrtest.c:1:

    My os is 64-bit Ubuntu 10.10. Since the code is exactly copied from offical user manual, i don't know what's wrong with it. Any help will be greatly appreciated.

    It is a known bug that the code in this manual is broken. You should instead use the source from the PVRScope examples as a starting point for your implementation of this API.
