.Net程序跑在Linux上

.Net越来越拥抱开源了，今天就试了如何让.Net程序跑在Linux上，果然再无人可以阻挡.Net的脚步了。 Linux Disibutaion:Open Logic 7.2 1、Install .NET Core SDK SSH进入Linux,输入如下命令： sudo yum install libunwind libicu curl -sSL -o dotnet.tar.gz https://go.microsoft.com/fwlink/?LinkID=827529 sudo mkdir -p /opt/dotnet && sudo tar zxf dotnet.tar.gz -C /opt/dotnet sudo ln -s /opt/dotnet/dotnet /usr/local/bin 这里我们就安装好了.Net程序运行的环境。 2、打开VS，新建一个控制台应用程序 3、将代码文件上传到Linux上这里我使用的是pscp command line工具上传文件到linux 代码上传成功之后，我们的程序要跑在linux上，还缺少一个project.json的文件。输入linux命令：vi project.json 进入vi编辑器加入如下内容： { "version": "1.0.0-*", "buildOptions": { "debugType":

背景在上一篇文章安装dotnet core ，已经安装好dotnet core了。之前只是安装成功了dotnet, 输入dotnet --info，可以确认安装成功了，但是在运行代码时，还是报错了，本章记录在部署好dotnet core后，到能运行控制台程序当中的错误。首先将项目用vs发布一下，然后把文件放到中标麒麟的系统上，在文件夹打开终端，执行 dotnet **.dll，结果如下： [root@gumis02 PublishOutput]# dotnet Beyondbit.ConsoleFrameworkNetStandard.IntegrationTests.dll Failed to load \ufffd=l, error: libunwind.so.8: cannot open shared object file: No such file or directory Failed to bind to CoreCLR at '/home/dotnet/shared/Microsoft.NETCore.App/2.0.7/libcoreclr.so' [root@gumis02 PublishOutput]# 错误 error : libunwind.so.8: cannot open shared object file: No such file or

问题 I am trying to build libunwind on Mac for both iOS and Mac, I was able to resolve few of the compilation problem. Building on Mac I configured the project using ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" And copied elf.h from google's breakpad project. https://google-breakpad.googlecode.com/svn-history/r1017/trunk/src/common/android/include/elf.h I get the following error now: /usr/include/elf.h:58:15: fatal error: 'elf.h' file not found #include_next <elf.h> Can anybody help me in solving

Is there a portable/standard-compliant way to get filenames and linenumbers in a stack trace?

问题 I've just read How to generate a stacktrace when my gcc C++ app crashes which is pretty old by now (5 years). Some answers suggest solutions allowing you to get, for every stack frame, the name of the function and an offset (within the stack I guess). But what I (and may others) really need is the source filename and line number where the call was made (assuming the code was compiled with debug information). One of the answers linked to a part of glibc which does this (libSegfault; see files
