“Proper way” to manage multiple versions of Python on archlinux

由 耗尽温柔 提交于 2019-11-30 08:11:10
So I have read this - https://wiki.archlinux.org/index.php/Python And it is clear from this wiki that I can install Python 2.7.2 via pacman -S python2 Is it reasonable for me to create a symlink to python2 ln -s python2 /usr/bin/python if I don't forsee myself switching to python 3.0 any time soon? Or is there a better way of managing multiple python versions like what I usually use on a debian system (update-alternatives --config python) or on a mac os x system (python select)? CLARIFICATION: What I am trying to find out is - what is the "best practice" of managing various python versions on

问题 I have code written in C++: #include <boost/python.hpp> char const* greet() { return "Yay!"; } BOOST_PYTHON_MODULE(libtest) { using namespace boost::python; def("greet", greet); } Now i want to import this dynamic library to python by: import libtest But I get: ImportError: /usr/lib/libboost_python.so.1.54.0: undefined symbol: PyClass_Type What should I do? My OS is Arch Linux. 回答1: Ok, I have found solution for this problem. The simplest options is to compile by: g++ testing.cpp -I/usr

问题 I just updated my arch linux system to the latest which includes gcc 7.1.1. Trying to build this: #include <functional> int main(int argc, char** argv) { return 1; } using the command clang++ main.cpp -std=c++1z results in the error: In file included from main.cpp:1: In file included from /usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/7.1.1/../../../../include/c++/7.1.1/functional:60: In file included from /usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/7.1.1/../../../../include/c++/7.1.1/unordered_map

一、 安装kmscon yaourt -S kmscon 二、 手动创建配置文件 /etc/fonts/conf.d/99-kmscon.conf ------------------------------------------------------------------------------ <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <match> <test name="family"><string>monospace</string></test> <edit name="family" mode="prepend" binding="strong"> <string>DejaVu Sans Mono</string> <string>WenQuanYi Micro Hei Mono</string> </edit> </match> </fontconfig> 三、 启动kmscon替换内核终端 1. 在某个tty显示 # systemctl enable kmsconvt@tty1.service 2. 在所有tty显示 # ln -s /usr/lib/systemd/system/kmsconvt\@.service /etc/systemd

ArchLinux 安装笔记：续 --zz

由 爷，独闯天下 提交于 2019-11-29 03:55:07
续前话 在虚拟机里调试了几天，终于鼓起勇气往实体机安装了，到桌面环境为止的安装过程可以看我的前一篇文章 《ArchLinux 安装笔记》 。桌面环境我使用的是 GNOME，虽然用了很长一段时间的 KDE，但是 KDE5 神一般的开机速度简直让人喜感，最后还是选择了 GNOME～ 安装 GNOME 桌面环境 安装 Xorg 本来以为需要安装整个 Xorg 事实上根本不用～ pacman -S xorg-xinit xorg-server xorg-twm xterm 安装 GNOME pacman -S gnome 如果你还需要 GNOME 自带的软件的话 pacman -S gnome-extra 顺便安装一下 GNOME 优化工具 GNOME Tweak Tool pacman -S gnome-tweak-tool 启动服务 Display Manager 显示管理器 GNOME 默认是用的是 GDM。 systemctl enable gdm.service Network Manager 装完 GNOME 进系统过后你会发现没地方设置网络，到 Settings 里面找到 Network 点开会提示你 NetworkManager 没有运行。 systemctl enable NetworkManager.service 然后重启电脑应该就能进入 GDM 了

64位archlinux运行steam

由 北慕城南 提交于 2019-11-28 19:51:21
1. steam 自带的OpenGL 库是过时的，运行可能会抱怨“Cannot find OpenGL GX” 之类的东西，看ArchWiki 「steam」条目，删除steam 自带的几个库。 2. 但是删除了steam 自带的那些库之后你需要在系统中安装新版的库，除去64 位的库之外（不可能还有人在用32 位的系统吧），看看有没有「lib32-mesa」和「lib32-mesa-libgl」，双显卡的lib32 还需要安装「lib32-intel-dri」，不要问为什么，不装上的话会非常非常卡，「primusrun」会不声不响失败，「optirun」会提示“cannot find opengl entry point xxxx” 之类的东西。 3. NVIDIA 的驱动需要安装「nvidia」而不是「nouveau」，同时安装「nvidia-utils」 和 「lib32-nvidia-utils」 。不过「bumblebee」安装的时候可能会有依赖冲突，看ArchWiki 的「bumblebee」条目，好象是同时安装「intel-dri」、「xf86-video--intel」、「bumblebee」和「nvidia」来规避依赖冲突。 4. 「bumblebee」是用来切换独显来运行某个程序的东西，但是「startx」进入桌面环境还是用的Intel 核心显卡，所以不要生成

set-up X11 Forwarding over ssh

由 和自甴很熟 提交于 2019-11-28 19:35:23
I'm attempting to set up x11 forwarding to monitor video on an embedded robotics platform yet I cannot seem to get the board to generate graphical output. I'm running Arch Linux on a Beagleboard xM wired directly over ethernet (though, I plan to use WiFi in the future). When I try to set the DISPLAY variable it will accept it but when I attempt to run an x11 application is says: (Object:287): Gtk-WARNING **: cannot open display: [displaynamehere] obviously [displaynamehere] was whatever I tried to set as the display, yet no display location seemed to work. What's weird is that whenever I
