After setting environment, QProcess::start() no effect.

[yogeshgokul]

Dear yogeshgokul,
Thank you !
I have ever set the env like : env <<"PATH = /home/azhang/env/tool.env" ,
but the result is same. Why?

Its hard to decide upon little information.
What if you add that path permanently in path variable using command promt or terminal and not with qt app itself ?
I just wanna be sure that adding

home/azhang/env/tool.env"

in path is making any difference anyway.
