I truly find the problem.
The path to the executable have Chinese character.
My windows's default language is gbk.
If I use utf-8 encoding for the shell, fork fail. If i use gbk, everything
goes fine.
The following is the test .
[ba...@bambo-notebook ARM9]$ pwd
/cygdrive/d/个人研发/ARM9
^^^^^^^^^^ Chinese directory name
[ba...@bambo-notebook ARM9]$ export LANG=en_US.UTF-8
[ba...@bambo-notebook ARM9]$ ./tvfork.exe
3 [main] tvfork 4900 fork: child -1 - CreateProcessW failed, errno 2
vfork failed.: No such file or directory
[ba...@bambo-notebook ARM9]$ export LANG=en_US.GBK
[ba...@bambo-notebook ARM9]$ ./tvfork.exe
I'm parentI'm chield.
