Data Alignment in QT ?

[Thà nh Viên Mới]

i want build VMAC ,but it use Data Alignment in Code
Ex:

int main(void)
{
    ALIGN(16) vmac_ctx_t ctx, ctx_aio, ctx_inc1, ctx_inc2;
    uint64_t res, tagl;
    void *p;
    unsigned char *m;
    ALIGN(4) unsigned char key[] = "abcdefghijklmnop";
    ALIGN(4) unsigned char nonce[] = "\0\0\0\0\0\0\0\0bcdefghi";
    unsigned int  vector_lengths[] = {0,3,48,300,3000000};
    #if (VMAC_TAG_LEN == 64)
    ALIGN(4) char *should_be[] = {"2576BE1C56D8B81B","2D376CF5B1813CE5",
                        "E8421F61D573D298","4492DF6C5CAC1BBE",
                        "09BA597DD7601113"};

int main(void)
{
    ALIGN(16) vmac_ctx_t ctx, ctx_aio, ctx_inc1, ctx_inc2;
    uint64_t res, tagl;
    void *p;
    unsigned char *m;
    ALIGN(4) unsigned char key[] = "abcdefghijklmnop";
    ALIGN(4) unsigned char nonce[] = "\0\0\0\0\0\0\0\0bcdefghi";
    unsigned int  vector_lengths[] = {0,3,48,300,3000000};
    #if (VMAC_TAG_LEN == 64)
    ALIGN(4) char *should_be[] = {"2576BE1C56D8B81B","2D376CF5B1813CE5",
                        "E8421F61D573D298","4492DF6C5CAC1BBE",
                        "09BA597DD7601113"};

can you help find Define ALIGN(16) in QT ?

this is define Data Alignment : _http://www.songho.ca/misc/alignment/dataalign.html

and SOurce code on QT Error:

Qt is C++, it doesn't enforce any data alignment. Everything that applies to C++ applies to Qt as well.

but when i run program error if use ALIGN(16)

With g++ you need to use it like this:

__attribute__((aligned(16)))

__attribute__((aligned(16)))

thank #define ALIGN(n) __attribute__ ((aligned(n)))

Is it possible to do an alignment on the entire project?
I'm using Qt with the VS2008 DevEnv, and there is the possibility to choose a general struct alignment of the project.
But I want to do this with my Makefile and qmake.
