Compiling error for android platform
Posted: Oct 6, 2010 2:57 AM

Plain Text

When I try to compile a simple simulink model with the ndk-build script
I get the following error:
grt_main.c:113: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token

the code where I get the error:
extern RT_MODEL *MODEL(void);
witch parsed as :
extern RT_MODEL_hellosimulink *hellosimulink(void);

RT_MODEL_hellosimulink is defined in hellosimulink.h
as:
/* Real-time Model Data Structure */
struct RT_MODEL_hellosimulink {
const char_T *path;
const char_T *modelName;
struct SimStruct_tag * *childSfunctions;
const char_T *errorStatus;
SS_SimMode simMode;
RTWLogInfo *rtwLogInfo;
RTWExtModeInfo *extModeInfo;
RTWSolverInfo solverInfo;
RTWSolverInfo *solverInfoPtr;
void *sfcnInfo;
...
...

from witch is made a type def in hellosimulink_types.h:
/* Forward declaration for rtModel */
typedef struct RT_MODEL_hellosimulink RT_MODEL_hellosimulink;

Does any one know why I get this error, when I compile it directly for android it does not give the error but when I compile it via the ndk-build script from android it wil give the error.
perhaps I am missing some compile options:

this this is the android.mk which is used with the ndk-build script:
