cross-compiling

问题 Here is my attempt to provide a dummy implementation of a part of java.awt related to Graphics2D : package java package object awt { object RenderingHints { type Key = Int val KEY_TEXT_ANTIALIASING = 0 val VALUE_TEXT_ANTIALIAS_ON = 0 } object Color { val GREEN = 0 } type Color = Int object image { object BufferedImage { val TYPE_INT_RGB = 0 } class BufferedImage(w: Int, h: Int, tpe: Int) { def createGraphics: Graphics2D = new Graphics2D } } class Graphics2D { def setColor(c: Color): Unit = ()

问题 Though there are many tutorials online on how to make a cross compiler, I am actually not getting it. I am using fedora 16 and already have gcc installed. I am not sure about binutils . How do I make a cross compiler for my own OS (the target) ? I was reading here on os dev wiki but I don't get it. I mean, what do I do ? I just don't follow there steps. Note : I want to build a cross compiler for the same architecture I am currently working on.I mean the same architecture that is running

问题 I wrote an application on my laptop (Ubuntu 14.04) that depends on GStreamer and would like to cross-compile it for my Yocto Linux target (iMX6S-Wandboard). How do I cross-compile the application so that it runs on the target board and is able to use the GStreamer libraries? Thank you, Toan UDPATE: My Makefile: PACKAGES = gstreamer-1.0 override CFLAGS += `pkg-config --cflags $(PACKAGES)` -Wall -Wextra "-DDATADIR=\"$(DATADIR)/\"" -ffunction-sections -fdata-sections override LIBS += `pkg-config

问题 I want to cross compile qt5 on RPi2 according to this RaspberryPi2EGLFS when I want to configure in step7 I see this error and I don't have any idea how to solve it. . . collect2: error: ld returned 1 exit status Makefile:91: recipe for target 'c++11' failed make: *** [c++11] Error 1 C++11 disabled. ERROR: Qt requires a C++11 compiler and yours does not seem to be that. Please upgrade. I use antergos x64. 来源： https://stackoverflow.com/questions/38232461/cannot-cross-compile-qt-5-7-for

问题 There are several tutorials on the web documenting how to cross-compile or cross-build Python for various embedded systems using some basic hacking and patching, like so: http://randomsplat.com/id5-cross-compiling-python-for-embedded-linux.html This worked well for me in the past, when I was using Python 2.7.2. In Python 2.7.4, some cross-compile functionality was finally included in the upstream build process, documented here: http://bugs.python.org/issue17086 https://mail.python.org

问题 Can I compile on mac so it will produce a windows binary? bind with windows dlls? (I have a windows machine to copy them from) How can I do so? clang and gcc are the compilers I can use. 回答1: The MinGW's toolchain can be built on OSX or most other unix/unix-like operating systems. Here's a link to the precompiled binaries: http://crossgcc.rts-software.org/doku.php?id=mingw-older-releases It works fine on my PowerMac G5 and as keith.layne says there is also a solution for Intel Macs. 回答2:

问题 I am bit confused with the terms of cross platform and cross compiler. Let me be first clear about the cross platform. When people talk about cross platform it means the architecture of the CPU, i.e, X86 and X64 ? or the OS i.e windows 32 bit or Windows 64 (server or desktop)? UNIX doesn't have different flavours like 64 bit or 32 bit. Why so? .NET and java is cross compiler language, what it means? When the program is compiled in .NET, we have to choose the option like X86, X64 or Any CPU.
