Re: [Interest] Size of libQt5Core in 5.3

2014-05-13 Thread Daniel Bowen
Thanks again for the info. Here's where I've gotten to so far. Starting from the last ./configure command line I mentioned, plus -no-feature- for every qfeature.txt item (minus LIBRARY, SETTINGS and REGULAREXPRESSION, since it doesn't build without those), I was at 4.3 MB stripped. Added to the

2014-05-12 Thread Daniel Bowen
In trying to reduce the size of Qt for an embedded environment, I've run into a couple problems that would be best solved by updates to the source. There was a comment that issues with 5.3.0 RC could be sent to the mailing list here. 1. If -no-gui is specified, qtdiag tries to build, but

I have an embedded environment where we use non-UI parts of Qt (Qt Core, Qt Networking) on an ARM host processor. We've been using 4.8.4 for a little while. There's some other changes coming to this code, and we've been looking to move to 5.x with the upcoming 5.3. After working through several

One other note: And since daylight saving transition dates and time tend to slightly drift from year to year, there's absolutely no guarantees of getting correct time conversion results; in general case 1-hour error is nearly inevitable. The timezone structure on Windows tracks the ST-DT

Let me state for the record that I do not use volatiles for thread synchronization. But the issue at hand is not whether a volatile can be used for full-featured thread synchronization, but whether it can be used by one thread to signal a second looping thread to quit. It can.
