"Unable to create directory" - unable to run test build with mingw provided by qt-installer about approvaltests.cpp HOT 5 OPEN

After Reading issue #196 i tried to change some settings in QT Creator.
By changing the generator from ninja to MinGW Makefiles it works.
This is the interesting part of the working output
__FILE__ == C:\Users\florian.fischer\Documents\inmach\src\approvalTest_problem\path_problem_demo\test.cpp
This time the filename contains backslashes instead of slashes.

from approvaltests.cpp.

I did some more investigation of this issue
g++ just copy the filname passed on commandline into FILE
when i use this command
g++.exe .//////.\\\\./.\\./foo.cpp
it prints
.//////.\\./.\./foo.cpp

I think you should normalize the Seperators.
It seems you have there something prepared.

Path::normalizeSeparators
Path::removeRedundantDirectorySeparators

But according to the debugger in qt-creator they are never called

Hello @Florian-Fischer-InMach

Many thanks for this clear report.

We've had a lot of trouble with the Ninja generator previously, and believed that we had worked through all the possible causes.

Here's what we wrote up previously about possible workarounds.

https://approvaltestscpp.readthedocs.io/en/latest/generated_docs/TroubleshootingMisconfiguredBuild.html

If none of those help, would you be interested in pairing with me, via screen sharing from your machine, to find a solution?

Hello @claremacrae
Sry for late answer. Was busy with other stuff.
I have read the workarounds but they do not solve my problem because they are all about getting abolute Paths.
My problem is: Wrong path seperators.
Ninja generates paths with "/".
getDirectorySeparator returns "".
string magic on path fails because of no match

I changed my Hack from the beginning to this:
Florian-Fischer-InMach@84e1a39

It simply calls normalizeSeparators to fix the sepearators in function setFileName

If you want further discussions we can do a screen sharing to improve this fix

I'm cross-compiling from Linux to windows, using mingw. And I bumped into the same problem. I solved it by patching

    std::string ApprovalTestNamer::getSourceFileName() const
    {
        auto file = getCurrentTest().getFileName();
 +       file = Path(file).toString();
        auto start = file.rfind(SystemUtils::getDirectorySeparator()) + 1;
        auto end = file.rfind('.');
        auto fileName = file.substr(start, end - start);
        return convertToFileName(fileName);
    }
...
    std::string FileUtils::getDirectory(const std::string& filePath)
    {
-        auto end = filePath.rfind(SystemUtils::getDirectorySeparator()) + 1;
-        auto directory = filePath.substr(0, end);
+        auto filePath2 = Path(filePath).toString();
+        auto end = filePath2.rfind(SystemUtils::getDirectorySeparator()) + 1;
+        auto directory = filePath2.substr(0, end);
        return directory;
    }

But in the end, Florian-Fischer-InMach@84e1a39 works as well. Why it is not in the master branch yet? This problem is known for at least 2 years.
