参照博客 java程序员技能树（如有侵权马上删除）经典回顾操作系统（ operation system OS）简介操作系统（operation system，简称OS）是管理计算机硬件与软件资源的计算机程序。操作系统需要处理如管理与配置内存、决定系统资源供需的优先次序、控制输入设备与输出设备、操作网络与管理文件系统等基本事务。操作系统也提供一个让用户与系统交互的操作界面。主要的操作系统嵌入式（ VxWorks 、 eCos 、 Symbian OS 及 Palm OS 、 iOS 、 Android ）类 Unix（ System V 、 BSD 与 Linux ） Microsoft Windows（ Windows XP 、 Windows 7 、 Windows 10 、） MacOS X（ MacOS 和MacOS X ） Google Chrome OS（ Google的轻型的、基于网络的计算机操作系统计划）编译原理基本概念编译原理即是对高级程序语言进行翻译的一门科学技术, 我们都知道计算机程序由程序语言编写而成, 在早期计算机程序语言发展较为缓慢, 因为计算机存储的数据和执行的程序都是由0、1代码组合而成的,

问题 I am trying to install the fancyimpute in my anaconda using pip install. but the error shows fail to install the ecos due to " Microsoft Visual C++ 14.0 is required." the link provided is expired. Does anyone know how to fix this? Thank you!

Does fgets() locks stdout preventing printf

阅读更多关于 Does fgets() locks stdout preventing printf

问题 I have a C program with two threads one of those threads is almost all the time blocked in a fgets() waiting for user input. The second thread may need to print to the terminal while the first one is blocked on fgets() . From my tests it seems that the program waits for the fgets() on the first thread to return and then the second thread can print. Is this who it works or could I print while the the other thread is blocked on the fgets() ? This implementations runs on eCos (embedded

阅读更多关于 GDB remote protocol: how to analyse packets?

问题 I have: A proprietary prototype ARM board (Cortex-M3 based) with eCos OS The board has the programmed RedBoot bootloader Serial line (RS-232) GDB debugger for ARM (arm-eabi-gdb) Host OS is Windows/Cygwin and/or Linux (actually, doesn't matter) Problem: GDB debugger cannot connect to the target over the serial line. What I want: is to sniff the packets of the GDB remote protocol in order to undestand whether the GDB stub on the target is alive and operating. Details: RedBoot has an option to

GCC MIPS-32 Calling Conventions / Stack Frame Definition

阅读更多关于 GCC MIPS-32 Calling Conventions / Stack Frame Definition

问题 There appears to be no definitive standardized stack frame and C language calling conventions (register usage and such) for the MIPS-32 Processor Architecture. That is, it appears to be completely up to the assembler/compiler tool chain to define their own stack frame and calling conventions. I've struggled to find a definitive reference of what conventions the GCC compiler uses for MIPS-32 instruction set. I'm specially using GCC cross-compiler on Cygwin that targets a MIPS-32 core being

Cygwin是一个在windows平台上运行的类UNIX模拟环境，是cygnus solutions公司开发的自由软件（该公司开发的著名工具还有eCos，不过现已被 Redhat 收购）。它对于学习UNIX/ Linux 操作环境，或者从UNIX到Windows的应用程序移植，或者进行某些特殊的开发工作，尤其是使用GNU工具集在Windows上进行嵌入式系统开发，非常有用 1：下载cygwin http://www.cygwin.com/ 2：安装一直默认下一步，这步是选择代理或者是直连，默认即可。这步选择下载点，默认第一个就可以。有的是国内的可能下载速度快一下，根据自己情况选择这一步选择安装的插件，一定要安装lynx (说明一下利用lynx,可以安装 apt-cyg ，利用apt-cyg就可以安装其他软件了），这里也可以安装其他的插件，例如wget,openssh等等。 3：安装完成，进入cygwin,安装 apt-cyg 1 ： lynx -source rawgit.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg 2 ：install apt-cyg /bin 4：安装其他软件 apt-cyg install vim apt-cyg install openssh 其他操作和linux基本相同。 ps：

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: This is a borderline SuperUser question. I've been using pip install <x> to add packages to my 3.6.2 installation, from powershell on Windows 10. I'm struggling to install CVXPY. Specifically, I've already upgraded setuptools and installed visual studio c++ 14. Also, I installed C++ 2008 as suggested by a github user: https://github.com/embotech/ecos/issues/53 . But, I couldn't implement her other suggestion (edit ecosmodules.c) because I dont think that file exists in the raw package I downloaded from github Below is the traceback when I
