cross-compiling

问题 I have a embedded device with MIPS arch working under OpenWRT system type: MediaTek MT7628AN ver:1 eco:2 machine: WRTnode2P processor: 0 cpu model: MIPS 24KEc V5.5 I want to compile compile a small program in C through my computer (ubuntu) #include <stdio.h> int main(void){ printf("HelloWorld"); return 0; } To compile it I use mips-linux-gnu-gcc command mips-linux-gnu-gcc -march=24kec -mabi=32 hello.c -o hello I send hello program to my device and make a chmod 755 chmod 755 hello When I try

问题 So I have been doing an assembly tutorial, and I got stuck in the very beginning. Project name: asmtut.s The Code: .text .global _start start: MOV R0, #65 MOV R7, #1 SWI 0 Right off the beginning I'm welcomed by 3 error messages after I try this line: as -o asmtut.o asmtut.s asmtut.s:6: Error: expecting operand after ','; got nothing asmtut.s:7: Error: expecting operand after ','; got nothing asmtut.s:9: Error: no such instruction: 'swi 0' I'm confused, because this is the exact code in the

问题 I am writing a Python2.7/PyQt4 programm under Ubuntu, but the application will be deployed on a Windows platform. One of the functions is that the application should capture several keystrokes (e.g. "Alt+A") even if it is not in focus/minimized. I use PyGlobalShortcut for this purpose, which is a Python/SIP wrapper around libxqt. Following the manual, I installed Qt4 + SIP and ran the pip install PyGlobalShortcut command, which automatically compiled and installed the libqxt library and the

问题 I'm building an System with Yocto/poky (morty branch). Building the image and the sdk works fine. I've installed the SDK on an machine (other than the build machine) to cross compile a tool. I've loaded the environment with source /opt/mydistro/2.2.1/environment-setup-cortexa7hf-neon-vfpv4-poky-linux-gnueabi Building a test file with arm-poky-linux-gnueabi-gcc test.cpp will fail with message /opt/mydistro/2.2.1/sysroots/x86_64-pokysdk-linux/usr/lib/arm-poky-linux-gnueabi/gcc/arm-poky-linux

问题 I am using VisualStudio CMake project on Windows machine. I am using an external SDK in order to cross compile my C++ program for Linux arm architecture . I added the SDK toolchain to cmakeToolchain path which is : /opt/poky-atmel/2.5.3/sysroots/x86_64-pokysdk-linux/usr/share/cmake/OEToolchainConfig.cmake and this is my CMakeLists.txt file : set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_PROCESSOR arm) set(Boost_USE_STATIC_LIBS ON) set(Boost_USE_MULTITHREADED OFF) set(Boost_USE_STATIC_RUNTIME

问题 I am trying to build GObject-Introspection on Ubuntu 14.04 using Mingw-w64. I am currently running 64bit Linux and trying to build for a 32bit Windows target. My first attempt used Python 2.7.8 installed in Wine, however, this did not work because Python's path separator was set to '\' (well '\') instead of Linux's '/'. Due to this I tried using the Python 2.7 in Ubuntu. Using the Python provided by Ubuntu doesn't get past the configuration step. Config.log shows the following: In file

问题 I'm trying to compile a C++ application for a Raspberry Pi Zero using GCC 8.2.1. I'm using this for a relatively large C++17 project that is being built using CMake, and I'm trying to cross-compile it on my x86-64 laptop. Even with the simplest code possible, I'm not able to compile it for ARMv6: int main() {} $ arm-linux-gnueabihf-g++ test.cpp -static -march=armv6 -mfpu=vfp -mfloat-abi=hard When running the file on the Pi, I get an Illegal instruction error, and readelf returns the following
