Write the bat file today, you need to connect two strings, but there are errors. The reason is this
Set vscomntools= "%vs140comntools%"
If not DEFINED "%vcinstalldir%" (
Call "%vscomntools%vsvars32.bat"
)
The path that is actually called after call is "C:\Program Files (x86) \microsoft Visual Studio 11.0\common7\tools\" vsvars32.b
At
So I need to get rid of the string header with a double quote and the middle of the double quotation mark.
On the Internet to find similar problems, refer to the link here is a good solution, is the use of DOS string manipulation techniques, links are as follows:
Concatinating string in a batch file
Finally my change is this, run correctly:
Set vscomntools= "%vs140comntools%"
If not DEFINED "%vcinstalldir%" (
Set Filepath=%vscomntools:~0,-1%vsvars32.bat "
Call%filepath%
)
By the way, the bat file string manipulation techniques are also affixed to, very useful, the English text is as follows (string manipulation technique original link):
dos-string Manipulation Basic string manipulation in batch like you is used to from the other programming languages.
