Subject: Re:Re: Problem to develop Qt5 application in Samba share
Date: Thu, 9 Jan 2020 09:58:58 +0000

To make it clear:

After the installation of Cygwin:
- QTDIR is not set. Setting QTDIR has no effect concerning the error.
- In /usr/bin is the file qmake_qt5. This is a symlink to ../lib/qt5/bin/qmake. I included this directory in PATH, cause I prefer to call qmake directly. If I call qmake-qt5 the errors are the same.

I suspect the reason for the errors is the Samba share. As I said, working with qmake on other shares is ok.

For many years i develop C/C++ applications in Cygwin with source code located in Samba shares. The shares are available on Windows with "net use ..." command. In Cygwin they are available via /cygdrive. Now I have to write applications using Qt 5. But there is a problem:

First i go to the project directory (cd ...) and write the source files. After that i call "qmake -project" (PATH includes /lib/qt5/bin),
If the project (source codes) is located on the local drive or a drive connected via SATA/USB, all is ok and the file *.pro is generated. If the sources are located on a Samba share, there are error messages:

---
Could not find qmake configuration file cygwin-g++.
Cannot find feature default_pre.prf
Cannot find feature default_post.prf
---

The Samba server is a Linux host.
This problem is the same on Windows 7 / Windows 10 and Cygwin 2.5.2 / Cygwin 3.1.2.
The problem does not exist if i use a Windows Qt Creator IDE from qt.io.

I couldn't find any hints on the internet, mailing lists, FAQ, ...

Can you help?

Many greetings

Raimund Paulus
