[ft] Problems about ftdmo29

[?????????????? ??????]

Dear freetype:


I use the jam(version 2.5.2) to compile the ftdmo29. My operate system is 
Window7 64bit.
I use jam like this
C:\Users\zgl\Desktop\ft2demos-2.9>jam,
and I get
Compiler is GCC with Mingw
...found 649 target(s)...

I find there are two failure of the target. Is the correct situation like this?
I didn't find anything in the C:\Users\zgl\Desktop\ft2demos-2.9\bin but I see 
the README file here and there should be all executables for the FreeType demo 
programs.
I see there  many files (.exe) in the C:\Users\zgl\Desktop\ft2demos-2.9\objs. 
However, when I click most of the them, they  just blink and close themselves. 
Only the ftgamma.exe and gbench.exe I can see the running results.The 
apinnames.exe, ftbenche.exe, ftchkwd.exe and... just blink. I want to know 
what's wrong here.


Could you give me some advice about my errors?


sincerely,
