Fail to open .py file..

Postby jiapei100 » Sun Jun 17, 2018 11:03 pm

Two issues are shown in my case:


1. Fail to open any .py file

2. Firmware Version 2.8.0 [out of date - click here to upgrade]

Any suggestions ?


Thank you
Pei

It's ending with .py for sure...

The file is at http://longervision.com/questions/test.py .

Actually, none .py file can be loaded, no matter what contents it has....

Hi, I don't have that issue on windows with v1.9.0. What OS are you on?

I can load your demo file fine.

I'm using Ubuntu 18.04, and I built openmvide from scratch, but using the most recent Qt 5.11.0 ...

So... not to be curt... but, if it's not a binary released by OpenMV how can I know what the problem is? Building the IDE yourself means you have to fix the issues yourself.

Just tested opening files in the IDE and everything works on Ubuntu.

Um, you may wish to search for the error string in the code and then to try to figure out what went wrong and then fix the error. I.e. do a global search through all files for "Could not open" and "Cannot open files of type". This will find the line of code that has an error. Then you have to fix it.

Application Ouput from within qtcreator:

Code: Select all

Hi, it looks like there's an error loading the mime-type database that's built-in to the IDE...

Not sure what to do to fix this. I've never had this error before.

>> MimeDatabase: Error loading :/qt-project.org/qmime/freedesktop.org.xml
>> Cannot open :/qt-project.org/qmime/freedesktop.org.xml: No such file or directory

You need to fix why this file cannot be found. Note that the file it's looking for gets built into the executable. ":/" on the front of a path means the application is looking for a file inside of a file system provided by qt that's inside of the executable.

You may wish to check the qt-resources that include the above "freedesktop.org.xml" file and determine why it's not getting built-in.

1) Looks like it may have something to do with qt-creator itself?
Check this page https://github.com/qt-creator/qt-creato ... ovider.cpp

Code: Select all

//        if (!fdoXmlFound) {
//            // We could instead install the file as part of installing Qt?
#if (QT_VERSION >= QT_VERSION_CHECK(5, 11, 0))
              const char freedesktopOrgXml[] = ":/qt-project.org/qmime/packages/freedesktop.org.xml";
#else
              const char freedesktopOrgXml[] = ":/qt-project.org/qmime/freedesktop.org.xml";
#endif
            allFiles.prepend(QLatin1String(freedesktopOrgXml));
//        }

2) I found my own freedesktop.org.xml at
/opt/Qt/5.11.0/Src/qtbase/src/corelib/mimetypes/mime/packages/freedesktop.org.xml
3) Are you using the NEWEST qt-creator? Looks like you are still using qt-4.8 ?

4) Is it possible to install qt-creator independently, instead of using your qt-creator?




Cheers
Pei

Hi, I'm using Qt 5.8 to build OpenMV IDE. This may be the issue.

Qt Version: 5.11.0
qt-creator: https://github.com/qt-creator/qt-creator/ git of June 20, 2018

By typing ./make.py directly, I still obtain the following error messages:
