I need to access the compile-time path of the solution/project in C++ code. This seems to be easy to solve by way of compiler option /D ("preprocessor definitions"), which allows to add C++ macros that are treated the same way as regular "#define" statements. Using the /D compiler switch, I can use environment variables such as $(SolutionDir) or $(ProjectName), which are resolved to their actual values before being passed to the preprocessor.
Example: /D _SOLUTIONPATH_="$(Solution
Resolves to: #define _SOLUTIONPATH_ "C:\svn\solutions\mysoluti
Unfortunately, the solution path contains backslashes which create unintended escape sequences in the string that is resolved from the environment variable. I did not find a way to create a properly escaped string. The problem has been discussed elsewhere without any solution:
Any of the following would qualify as a solution to my question:
- A way to create a properly escaped C++ string from the $(SolutionDir) environment variable.
- A way to make $(SolutionDir) a path with forward slashes instead of backslashes, which would eliminate the necessity to escape anything.
- A way to define a C++ macro that contains the length of the $(SolutionDir) string, rather than the string itself.
- Any other way to make the compile-time solution path available in the C++ code without going through compiler option /D.
