C call makes exception #13 wake...

[proxy]

a more reliable way to change the packing for a whole structure is like this:


(GCC Specific)

Code: Select all

#pragma pack (push, 1)
struct MyStruct {
uint16_t member1;
uint32_t member2;
};
#pragma pack(pop)

this structure will have a size of 6 which is what is wanted.

It doesn't work for me... does it matter if I use the -O3 param when compiling.

Re: Packing structure members...
I use the -fpack-struct switch with GCC and it works for me.

I tried that too but GCC wouldn't even execute then...

what sort of GCC version are you using ?

`-fpack-struct'
Pack all structure members together without holes.

*Warning:* the `-fpack-struct' switch causes GCC to generate code
that is not binary compatible with code generated without that
switch. Additionally, it makes the code suboptimal. Use it to
conform to a non-default application binary interface.

So i'd rather use a structure-local stuff than trying to pack all structures by default ...

are you sure the pragma doesn't work for you? I have never seen any case where it fails to perform as expected...perhaps you misused it?
