我正在使用Debian,并按照Rust的编译说明:
我试过几次,但最后总是出现以下错误:

我正在尝试从Datastax网站构建cpp驱动程序。我在ubuntu 12.04。在说明中,要将ppa:linuxjedi/ppa添加到存储库中,以便可以安装libuv。不管我得到了什么

This may mean that the package is missing, has been obsoleted, or

我正在寻找一种在linux主机上的朱莉娅脚本中捕获SIGINT的方法,但我无法理解如何管理信号。
在REPL中:
julia > try
sleep(1000)
catch e

end
Ctrl-C
[ Info: interrupt captured!
相反,执行demo.jl
try
sleep(1000)
catch e
@info "interrupt captured!"
end
给予:
terminal> julia demo.jl

我一直在使用launchpad.net为Xenial、Bionic和现在的焦点构建许多我的项目。
当我试图完成我的项目列表时,其中一个构建让我感到悲伤,因为我说不需要安装依赖项。从我在网络上发现的情况来看,这种情况似乎发生在缺少依赖项时(至少就launchpad.net而言)。以防万一,我今天重新运行了一个构建,大约20小时后,它仍然失败。同样的错误。
还有什么东西我遗漏了吗?

我已经从安装了uv4l raspicam驱动程序(用于rasberryPi的camera CSI摄像头模块的驱动程序)。安装后,当我使用SimpleCV时,我遵循删除了视频预览,并将分辨率设置为640x480。它可以工作,但现在我在SimpleCV中设置摄像头属性时遇到了一些问题,比如宽度和高度。当我运行时:
from SimpleCV import *
c = Camera()
im = c.getImage()
im.show()
它以64x64窗口运行,而不是640x480窗口。因此,用户修复了这个问题,但当我使用以下命令更改代码时:

根据对和的描述,我的理解是在dist tarball中不需要Makefile.am。
我试过了
wget https://dist.libuv.org/dist/v1.44.2/libuv-v1.44.2-dist.tar.gz
tar xf libuv-v1.44.2-dist.tar.gz
cd libuv-1.44.2/
mv Makefile.am Makefile.am.bak
./configure
make
运行make时会出现错误。
