How to register FUSE filesystem type with mount(8) and fstab?

无人久伴 提交于 2019-12-03 03:37:55
问题 I've written a small FUSE-based filesystem and now the only part's missing is that I want to register it with fstab(5) to auto-mount it on system startup and/or manually mount it with just mount /srv/virtual-db . How can I achieve this? I know, I can just run /usr/bin/vdbfs.py /srv/virtual-db from some init script, but that's not exactly pretty. I'm sorry because this may be not exactly a programming question, but it's highly related, as the packaging and deployment is still the programmer's

For example: returns: bad flag in substitution command 'i' What should I do to get the GNU version working?

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: I program C++ applications on (Ubuntu) Linux and compile them to 2 operating systems: natively to Linux by using "g++" (GNU C++ compiler) and cross-compile them to Windows by using "i386-mingw32-g++" (MinGW C++ cross-compiler). Now, I am trying to cross-compile "OpenGL" applications (from Linux to Windows) - for that I need some OpenGL library files. As an implementation of OpenGL, I use "Mesa 3D" open source library. Fortunately, Ubuntu offers "precompiled" mesa3d libraries ( libgl1-mesa-dev and libglu1-mesa-dev ) for Linux, but

I've spent the weekend getting the IBM Client SDK for Informix working on Debian (because most directions on the process are lacking, so this took a weekend to sort out.) I can connect and run queries to a remote Informix server with isql now - no problem. Now I need PHP to connect so that I can render output to apache. This syntax; <?php try { $dbh = new PDO("informix:DSN=InformixDB", "username", "password"); } catch (PDOException $e) { echo $e->getMessage

Install GNU GCC on mac

I was wondering what the best way to install GNU GCC on OS X would be. Things to consider: I don't want to use MacPorts, fink, homebrew or any other third party package manager. I would like to use the latest GCC, compiled from source, if possible. I need the existing GCC (hardlink to clang) to remain the default, but to easily be able to use GNU GCC when I need to. I would like to avoid modifying the code if at all possible. EDIT: Success! Using
