kill - does it kill the process right away?

由 末鹿安然 提交于 2019-12-22 09:00:09
问题 what does kill exactly do? I have a parent process which is creating 100 (as an example) child processes one after another. At the end of any child's job, I kill the child with kill(pid_of_child, SIGKILL) and I cannot see that in ps output. But if something goes wrong with the parent process and I exit from the parent process with exit(1) (at this point only 1 child is there - I can check tht in ps ), at that point I see a lot of <defunct> processes whose ppid is pid of parent process. How is

问题 I'm working on a Ruby script that will need to be deployed onto systems without a ruby interpreter. It will need to run on FreeBSD systems which uses the ELF format. I know there is a ruby2exe project to compile ruby scripts to run on Windows, but is it easy or even possible to do that on other operating systems? 回答1: Have you checked whether Rubinius or JRuby would allow you to precompile your code? 回答2: Aside from bytecode that requires a VM to run, Ruby cannot be compiled. It is an

Getting GCC in C++11 mode to work on FreeBSD

由 六月ゝ 毕业季﹏ 提交于 2019-12-22 05:11:34
问题 How do I get a working GCC-based C++11 setup on FreeBSD 10? It seems that the standard library that comes with recent GCC versions on FreeBSD is broken. I've installed the port gcc49 and then try to compile this: #include <string> int main() { auto str = std::to_string(42); str = std::to_string(42ull); str = std::to_string(4.2); str.clear(); return 0; } This gives me an error: g++49 -v -std=c++11 foo.cc Using built-in specs. COLLECT_GCC=g++49 COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc49/gcc

How to color a prompt on FreeBSD/cshrc?

由 自作多情 提交于 2019-12-20 10:45:07
问题 I'm being put in charge of managing a bunch of servers, I want to set up my prompts on each of them so that I don't get confused as to where I am logged in to. I've edited my .cshrc files and put this in them: set prompt=`whoami`@`hostname -s`:$cwd'$ ' But I'd like to color that prompt so it stands out a bit more. Maybe green with white text or something. How can I do that? I'm not very familiar with the shell syntax. I'm SSH-ing in from the standard terminal that comes with Ubuntu, if that's

Does GPL code linking with proprietary library depend which is created first? [closed]

由 老子叫甜甜 提交于 2019-12-20 10:28:24
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Microsoft creates their windows and MFC DLL library, etc. An open source develop write a new MFC application and release the source code as GPL. The app has to link with the MS DLL/libraries to run in Windows, but I don't think anyone can argue that we now have the right to force the Microsoft's GPL their DLL.
