Re: [Interest] Qt5 cross compilation issues on Tegra3
that will depend on your target build system. Nothing to do with ubuntu. Look what embedded build system you are using. See in its documentation how to add new packages. then download libxcb and compile. But do you really need xcb. I have never compiled qt5 till now. But isn't xcb needed only for x11 based builds. I think on embedded devices eglfs is the recommended approach. regards, Pritam From: interest-bounces+pritam_ghanghas=infosys@qt-project.org [interest-bounces+pritam_ghanghas=infosys@qt-project.org] on behalf of Ramakanthreddy_Kesireddy [ramakanthreddy_kesire...@mahindrasatyam.com] Sent: Tuesday, February 26, 2013 6:46 PM To: Thiago Macieira; interest@qt-project.org Subject: [Interest] Qt5 cross compilation issues on Tegra3 Hi, Could you please let me know where can I get the Qt5 development packages(ubuntu) required for Qt5 configure and how can I install in sysroot for the below errors?

Re: [Interest] Qt5 cross compilation issues on Tegra3
Hi, Actually as neon support is enabled for Tegra3 targetfs, -mfloat-abi=soft is disabling the neon. Please suggest the changes we need to make in qmake.conf as attached. Br, Ramakanth From: interest-bounces+ramakanthreddy_kesireddy=mahindrasatyam@qt-project.org [interest-bounces+ramakanthreddy_kesireddy=mahindrasatyam@qt-project.org] on behalf of Donald Carr [sirsp...@gmail.com] Sent: Friday, February 22, 2013 7:06 AM To: Thiago Macieira Cc: interest@qt-project.org Subject: Re: [Interest] Qt5 cross compilation issues on Tegra3 Yuck, I suspect I might be somewhat to blame. There is so much wrong, I might be causing some of it. If you create a device (TM) mkspec as evident in the device subdir, it automatically includes a header and footer pri file, which try to do the right thing but in a braindead misguided fashion. One of the things that the footer does is automatically append -mfloat-abi=softfp unless you explicitly state that you are using hardfp support. My justification for this stupidity is below, if you care. This is limited to mkspecs in the device folder, and this was meant to ease optimal usage/compilation of Qt since: 1) Our documentation doesn't cut it (cross compilation) 2) Our customers are normally complete dolts, even the chipset dudes who appear to love living in complete ignorance of modern Linux stacks, toolchain progress and the impact of compiler flags on generated code. Since we never actually got the device crap to a point where it was widely adopted, understood and used, this lingers as a semi-functional documentational sore point. I have meant to address this oversight for absolute ages. Cheerio, Donald This was introduced due to the us (possibly just me) deciding that we always wanted -mfloat-abi=softfp _or_ -mfloat-abi=hard, and never -mfloat-abi=soft which is the default for most toolchains I have encountered as part of BSP packages. On devices like the Raspberry Pi -mfloat-abi=softfp made a hell of a difference over -mfloat-abi=soft, and at a point where the hardfp enabled build did not exist.

Do you have a mix of two toolchains in your mkspec. I see that g++ and ld are coming from different paths.
