Strange shell error (Qmake, Win32, MinGW)

[tksharpless]

I have a problem with a Qt project that specifies install commands. My build toolkit is a standard, recent MinGW installation, external to Qt 4.6. The install part of the build fails with this message:

zsh: command not found: mkdir

Which is weird since I can't find any zsh executable on my system.

I got exactly the same result from running "make install" from the MS shell in the build directory, which is also weird as it is not supposed to know about make. But it did, because some old install of Hugin had put a dir containing gnu make on PATH (but that dir has no zsh.exe either). I removed that dir from PATH.

However, the build continues to fail when run from Qt Creator, but works fine if I run "make install" from the Msys shell.

I _think_ this project worked with a previous installation of Qt -- 4.4 or 4.5.

Any insights?

And can anyone point me at documentation of how Qt Creator decides what shell to run, and how it sets that shell's environment?

Thanks, Tom

I don't know any settings of MingW, but it seems you set the default shell of MingW to zsh and not bash (if that is at all possible).

I don't think it is, especially since zsh does not exist on this system.

The root problem was clearly that unsuitable version of gnu make found in the Hugin directory. After I took that off the path, _and_ rebooted, and ran "rebuild all" in Qt Creator, the install still failed, but the error message was from MS command shell, saying that it could not find "test".

Then I ran qmake, after which the build now works. Evidently qmake has somehow enabled the MingGW shell environment, that the Makefile expected all along. Why it did not do so before (and why "rebuild all" doesn't run qmake) I will leave to the Qt internal gurus.

mkdir is not a standard command in zsh. It is available if you install the files module.

I'm very sure that error means that you're using zsh and it can not find the command mkdir.
