I started with a new image and loaded ConfigurationOfNativeBoost. But it's still not working.
First I do a call to get a handle: "UEnumeration* ucal_openTimeZones(UErrorCode * ec)" self nbCall: #( void* ucal_openTimeZones_48( ICUErrorCodeNB* anErrorCode ) ) module: 'libicui18n.dylib' This call succeeds. I store the result in a subclass of NBExternalHandle using the #value: class method. In the second call I want to use the handle to retrieve the next element: self nbCall: #( char* uenum_next_48(ICUEnumerationNB* aHandle, int* nil, ICUErrorCodeNB* anErrorCode ) ) module: 'libicuuc.dylib' But this call still causes the image to disappear. I think the nil and errorCode arguments are all right. Is there something wrong with the first argument? Jan.
