U++ needs TLS. Mingw does not provide one.

Save yourself the trouble and get free M$ Windows SDK (with compiler).

Under Chinese version windows, vs2005+(vs2003 excepted) cannot compile utf8 encoded source files properly.There're will be many C2001 errors,therefore I chose mingw to take the compiler.

Can I use other thread library?If can, what have to pay attention?

Because I look at upp just now two days, if asked the question is too bothersome or too tired with, I felt that was sorry very much.

Hello, Jiang.

You didn't say about your version of GCC.
With 4.4.1 version of TDM's GCC such a package can be compiled.

Unfortunately, this does help in not getting the error but as reported here:
http://www.ultimatepp.org/forum/index.php?t=msg&th=4583& amp;start=0&
it is very slow.
At least that is with Apps using GuiLock mechanism.

Matthias

Koldo, have you tried the latest build (08/10/2009) ?
If that works I will also update my MingW installation.

Matthias

Yes, that is unfortunately true. We were trying to workaround this problem for years.... to no avail. The only known fix is to set your XP locals to English...

TLS is quite important building block of any serious MT effort, thus I guess it will be limiting issue anyway.

Of course, depends on what are you planing to do with MT. If performance is your concern, a good TLS implementation is a big plus.

Hello Matthias

Sender Ghost did it before me!

TDM developed a new GCC 4.4.1 in 2009-10-08 (http://www.tdragon.net/recentgcc/)

In the TDM main page, News area, they say:

Quote:

2009-10-08
The second TDM release of GCC 4.4.1 is finally available, fixing the bug that caused a major slowdown in nearly any non-trivial program. (This is the only change from the first release.)

This matches exactly with the problem we found in http://www.ultimatepp.org/forum/index.php?t=msg&goto=228 00&

GuiLock and GuiMT examples now work perfectly (my own MT applications too).

Really good news for MinGW supporters Smile

.

Best regards
Koldo

PD. If anybody uses SysInfo Bazaar package (in windows), please do not forget to copy additional include and lib files over new mingw install as documented

Best regards

Intereseting. Do you thing that they have not better TLS support?

Have you checked in disassembler?
