Log function detect OSX system language and OpenGL version incorrectly

Log function detect OSX system language and OpenGL version incorrectly
By default, Stellarium should display in the language that system is using....But on OSX, Stellarium cannot detect the system language.
The OpenGL version supported by my macbook air mid-2012 should be up to 4.1, but stellarium display it as 2.1

A fix for locale issue has been committed as revision 6722 of the trunk branch in Stellarium's Bazaar repository at Launchpad:

About detecting OpenGL version incorrectly - can you give more info?

[henrysky (henry-leung-2010)]

http://support.apple.com/kb/HT5942
My Macbook air mid-2012 should support up to OpenGL 4.1
I have done a test to confirm (the image)...
But in the log, stellarium only detect my computer only support up to OpenGL2.1

[Alexander Wolf (alexwolf)]

This is very odd because Stellarium getting info about OpenGL version from Qt and "driver".

Line below was get from Qt:
OpenGL versions supported: "1.1, 1.2, 1.3, 1.4, 1.5, 2.0, 2.1"

Line below was get from driver (reinterpret_cast<const char*>(glGetString(GL_VERSION))):
Driver version string: "2.1 INTEL-8.24.11"

[henrysky (henry-leung-2010)]

Maybe this is a Qt bug???
I get 4.1 Intel-8.24.11 from another software (I am not sure if they are using Qt or not)

[Alexander Wolf (alexwolf)]

Henry, can you check latest code?

[henrysky (henry-leung-2010)]

no, the driver version string is still 2.1 INTEL-8.26.34

[gzotti (georg-zotti)]

I am pretty sure the Mac has to be initialized in some different way to enable higher OpenGL context. Some developer with a physical Mac could find this out. As always, patch welcome!

[Alexander Wolf (alexwolf)]

Could you check this issue in last beta?

[henrysky (henry-leung-2010)]

Still the same, I did notice the last beta is significantly slower (Things not smooth) than current stable on MacOS 10.12.3

[Guillaume Chereau (guillaume-chereau)]

At least for the OpenGL version, this is expected since stellarium doesn't set OSX 'Core Profile', and specifically set the version to 2.1 in the code. Somehow I don't think this should affect the speed though.

[gzotti (georg-zotti)]

Ah, this means Macs really deliver a 2.1 format, while e.g. on Windows the system is allowed to deliver higher format? As long as the requested 2.1 does not cause problems, it should be OK. The bug can be closed then, IMHO: locale is fixed, and 2.1 detection is correct. Maybe the log messages can be clarified?
