Crash O2

Question

Ben EMCC -o2 ile bazı temel test kodu derlemek çalışıyorum, ben anlamıyorum bir nedeni, derleme bir noktada başarısız:

D:\Projects\jsport>call emcc "../src/lib.cpp" -o emscripten_test-min.js -O2 -s EXPORTED_FUNCTIONS="['_testFct']" -s RESERVED_FUNCTION_POINTERS=1

O2 seçeneğini kaldırırsam, aynı kod tam olarak derlenir ve Javascript'ten çağrılabilir.

Bunu nasıl düzeltebiliriz?

ben çalışıyorum kod derlemek için:

Lib.h:

#ifndef LIB_H 
#define LIB_H 

extern "C" { 

typedef void (*invoke_oncomplete_callback_t)(int, const char*, const char*); 

void testFct(const void *arr_data_rgba, int arr_width, int arr_height, int job_id, invoke_oncomplete_callback_t callback); 

} 

#endif //LIB_H 

Lib.cpp:

#include <sstream> 
#include "lib.h" 

// Internal C++ library functions 
namespace impl { 

void testFct(const void *arr_data, int arr_width, int arr_height, int job_id, invoke_oncomplete_callback_t callback) 
{ 
    // Call the callback with the result 
    std::stringstream ss; 
    ss << "Inversion done in " << 0 << "s"; 
    callback(job_id, "", ss.str().c_str()); 
} 

} // namespace impl 

// Exposed C library function 
void testFct(const void *arr_data, int arr_width, int arr_height, int job_id, invoke_oncomplete_callback_t callback) 
{ 
    impl::testFct(arr_data, arr_width, arr_height, job_id, callback); 
}

EMCC_DEBUG = 1 ile

Answer 1

, kaza yerel bir derleyici ararken bir sorun nedeniyle gibi görünüyor.

Ortam değişkenini ayarlama EMCC_NATIVE_OPTIMIZER = 0, derlemeyi düşürmenin dezavantajı ile sorunu düzeltir.
