在qmake命令行中定义一个字符串 [英] Define a string in qmake command line

问题描述

我需要将一个字符串作为定义传递给我的源代码，这是一个base64编码的字符串（可能包含 / 和
$ b

  qmake DEFINES + = SERIAL = \\\\f9a / z\\\\
 qmake DEFINES + = SERIAL = \f9a / z\
 qmake DEFINES + =SERIAL = \\f9a / z\\\\
  

G ++应该得到像这样的序列：

  g ++ -DSERIAL = \f9a / z\
  
 
  >  qmake DEFINES + = SERIAL = \\\\\\\\f9a / z\\\\\\\\ 
  
在脚本语言中： 
 
 
 DEFINES + = SERIAL = \\\\\\+ str +\\\\\\\ 
  
 
I need to pass a string as a definition to my source code which is a base64 encoded string (so may contain / and "). I'm using qmake and g++. I've tried so many combinations, but neither works:
qmake DEFINES+=SERIAL=\\\"f9a/z\\\"
qmake DEFINES+=SERIAL=\"f9a/z\"
qmake DEFINES+="SERIAL=\\"f9a/z\\\""
G++ should get the serial like this:
g++ -DSERIAL=\"f9a/z\"

解决方案
In bash:
qmake DEFINES+=SERIAL=\\\\\\\"\"f9a/z\\\\\\\"\"
In a scripting language:
"DEFINES+=SERIAL=\\\\\\\"" + str + "\\\\\\\""
