Fix build on windows #18

Closed kkretzschmar closed 8 years ago

kkretzschmar commented 8 years ago

Hi Juan, thanks for fixing the issues in my code.

I have a strange error message which came up after I applied the last PixInsight update (see attachment). At the same time I also updated the PCL branch from github.

The error is a fatal error reporting "Error writing settings data (bool)" when I exit PixInsight. Even when I do nothing with PI justing exiting, this error message occurs and PI hangs, I have to kill the process.

When I have process open (e.g. Dynamic crop) and exit PI the I get in addtion an API error:

"Settings: Error writing local integer data: Interfaces/DynamicCrop/Geometry/Top"

First I thought it has to do with my client development, but even when I disable my plugin the error occurs.

It seems to be a problem with file I/O. The problem occurs also when I try to overwrite an existing image with "Save as"

Have you seen such a problem before?

I am using Ubuntu 14.04 with the latest PI core version. Reinstallation did not work.

Thanks, Klaus

P.S. I am writing this bug message here, since I am not sure whether it belongs to my development. But I think not ...

Hi Klaus,

This problem is very strange. I have seen something similar (bool settings write error on exit) on a Windows 7 machine. However, this has never happened on the rest of our testing machines, including Linux, OS X and Windows (7, 8.1 and 10) physical and virtual machines. Indeed it looks like a file I/O problem, perhaps caused by a permissions issue in your case (typical problem on UNIX/Linux environments), or maybe a rare Qt bug. Anyway, I only saw this once and haven't been able to reproduce it.

Try resetting all application settings by launching the application as follows:

$ PixInsight --uninstall

This will remove all settings created by the core application and all scripts and modules. Let me know if this helps.

HI Juan, thanks.

This application failed to start because it could not find or load the Qt platform plugin "xcb".

Reinstalling the application may fix this problem.

There is no libqxcb.so neither in the installation directory nor in the lib subfolder

Sorry, I found it now in lib/qt-plugins/platform

ldd on libqxcb.so shows that libQt5XcbQpa.so.5 cannot be found.

libQt5XcbQpa.so.5 => not found

Finally I made it with the script: PixInsight.sh --uninstall.

Yes, it solved the problem, thanks !!
