Hi Greg!

I can attempt tp answer your question about
-fno-keep-inline-dllexport.

I've used -fno-keep-inline-dllexport when building Qt with mingw-w64.

The issue was that I would run out of memory when linking QtGui.dll
(or maybe QtCore.dll or maybe both).  The link process would use
in excess of 3 GB.  Running the build with -fno-keep-inline-dllexport
made in possible for me to build Qt on a 4 GB machine.  Linking the
dll was still memory intensive, but less.  I think when using
-fno-keep-inline-dllexport the linking step took 2+ GB of memory.

>From John's comment I assume something similar is going on with
wxWidgets.


Good luck.

Hi Greg,

GCC versions before 4.5 didn't emit class member functions into DLLs if 
they were declared with the "inline" keyword. This tended not to be a 
problem, because their full definition is available and inlinable to any 
user of the class. But as of 4.5 GCC was changed to match Microsoft 
Visual C/C++ behavior by also emitting said functions into the DLL.

The more inline class member functions, the more memory it takes to link 
the DLL. wxWidgets grew big enough that when the 4.5 change came around, 
suddenly there were too many inline class member functions to fit in 
link-time memory, and the linker would fail.

The "-fno-keep-inline-dllexport" option reverts to pre-4.5 behavior by 
not emitting inline class member functions into a DLL, allowing software 
like wxWidgets (monolithic) to link successfully. The only downsides to 
using it are that it breaks Microsoft compatibility (almost always not a 
problem with C++), and that you can't take the address in the DLL of one 
of said functions (which you shouldn't be doing anyway for inlines).

You are. The TDM-GCC installer intentionally avoids the registry like 
the plague. All is done through file magic. :)

In my never-ending war on misconceptions regarding C++:
1. inline does not tell your compiler to inline. It is merely a hint and
the fact that some compilers take it as a serious hint is a coincidence.
Nothing in the C or C++ language says there is even the slightest
guarantee. The point of inline is to be able to write inline definitions of
functions, and respect the One Definition Rule. But you knew that already I
suppose ;-)
2. There is absolutely no problem in taking the address of an inline
function. It is very legal. See for example
http://stackoverflow.com/q/3318322/256138
3. I do believe this compiler option makes GCC behave in a non-standard
way, but I haven't checked that myself.

Nevertheless, since ld is too inefficient, this option was necessary to
make it work for stuff like wxWidgets (Qt also added the option to its
build).

Cheers,

Ruben

Hey,

I already remove all those _r time function from pthread.
Can you check the latest head?
As this patch won't apply
