Build a 3rd party library from source within an existing Qt project

孤街浪徒 提交于 2021-02-06 11:09:45
问题 My project requires a version of zlib that isn't present on all target machines, so I want to build zlib from source in my project. Then when I make my project, it should first build zlib so it can be linked to when compiling my project. One complication is that zlib requires configure to be run before make can be run. I'm not even sure where to start here. Is there functionality built in to Qt Creator for importing 3rd party library source code like this, or do I need to code out a custom

【Nginx安装】CentOS7安装Nginx及配置

Nginx是一款轻量级的网页服务器、反向代理服务器。相较于Apache、lighttpd具有占有内存少,稳定性高等优势。**它最常的用途是提供反向代理服务。** 安装 在Centos下,yum源不提供nginx的安装,可以通过切换yum源的方法获取安装。也可以通过直接下载安装包的方法,**以下命令均需root权限执行**: 首先安装必要的库(nginx 中gzip模块需要 zlib 库,rewrite模块需要 pcre 库,ssl 功能需要openssl库)。选定**/usr/ local**为安装目录,以下具体版本号根据实际改变。 1.安装gcc gcc-c++(如新环境,未安装请先安装) $ yum install -y gcc gcc-c++ 2.安装PCRE库 $ cd /usr/local/ $ wget http:/ /jaist.dl.sourceforge.net/project /pcre/pcre /8.33/pcre- 8.33.tar.gz $ tar -zxvf pcre- 8.36.tar.gz $ cd pcre- 8.36 $ ./configure $ make && make install 如报错 :configure: error: You need a C++ compiler for C++ support 解决 :yum install

问题 I have work this for weeks, very hope for your help!!! please forgive my poor english. First, I think it's necessary to describe the Application Scenario: what data I want to decompress?---- the data is come from the network traffic of the internet . In these traffic, there are some data are compressed by gzip and store in the http or tcp packet, if the data size is huge and large than the maxlength of tcp payload, it will be sliced and transmiss. I can extract the compressed data from these

win10下安装Cygwin配置gcc编译环境

China☆狼群 提交于 2021-02-02 12:20:43
首先要说明的是,我个人安装cygwin的用途是为了使用kenlm工具训练通及语言模型。 注: 统计语言模型工具有比较多的选择,目前比较好的有srilm以及kenlm,其中kenlm比srilm晚出来,训练速度也更快,而且支持单机大数据的训练。 因为使用该工具在Linux环境下比较方便,我是win10系统,所以需要使用cywin 64模拟linux环境 (先确保linux环境已经按照1.36.0的Boost和zlib。) 然后gcc版本需要是4.8.2及以上。 之后出现的界面,默认为第一个选项,意思是从网络下载并安装(从官网下载的不是完整安装包,只是安装引导程序) 之后都没什么问题,就默认下一步就ok了 然后会出现一个界面,ustc是中科大的镜像,neusoft是东软的镜像下载速度较快,当然也可也选香港的(一个hk的什么网站,很好找)。 在搜索框出处分别搜索 gcc-core、gcc-g++、make、gdb、binutils,以上所有项目都在 devel 文件夹下。点击想要下载的包后面的skip即可。 然后点击下一步。 将安装目录下的 bin目录 添加到 Path 环境变量。我用的是 windows 10,添加环境变量的具体方法自行百度。 最后在terminal中 输入gcc -v + enter,出现如下界面即为安装成功。 来源: oschina 链接: https://my

【学相伴】Nginx最新教程通俗易懂-狂神说

Nginx - 学相伴 分享人:秦疆(遇见狂神说) 公司产品出现瓶颈? 我们公司项目刚刚上线的时候,并发量小,用户使用的少,所以在低并发的情况下,一个jar包启动应用就够了,然后内部tomcat返回内容给用户。 但是慢慢的,使用我们平台的用户越来越多了,并发量慢慢增大了,这时候一台服务器满足不了我们的需求了。 于是我们横向扩展,又增加了服务器。这个时候几个项目启动在不同的服务器上,用户要访问,就需要增加一个代理服务器了,通过代理服务器来帮我们转发和处理请求。 我们希望这个代理服务器可以帮助我们接收用户的请求,然后将用户的请求按照规则帮我们转发到不同的服务器节点之上。这个过程用户是无感知的,用户并不知道是哪个服务器返回的结果,我们还希望他可以按照服务器的性能提供不同的权重选择。保证最佳体验!所以我们使用了Nginx。 什么是Nginx? Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器,同时也提供了IMAP/POP3/SMTP服务。Nginx是由伊戈尔·赛索耶夫为俄罗斯访问量第二的Rambler.ru站点(俄文:Рамблер)开发的,第一个公开版本0.1.0发布于2004年10月4日。2011年6月1日,nginx 1.0.4发布。 其特点是占有内存少,并发能力强,事实上nginx的并发能力在同类型的网页服务器中表现较好

Understanding the zlib header; CMF (CM, CINFO), FLG, (FDICT/DICTID, FLEVEL); RFC1950 § 2.2. Data format

点点圈 提交于 2021-01-29 03:55:53
问题 I am curious about the zlib data format and trying to understand the zlib header as described in RFC1950 (https://tools.ietf.org/html/rfc1950). I am however new to this kind of low level interpretation and seem to have run afoul with some of my conclusions. I have the following compressed data (from a PDF stream object): b'h\xdebbd\x10`b`Rcb`\xb0ab`\xdc\x0b\xa4\x93\x98\x18\xfe>\x06\xb2\xed\x01\x02\x0c\x00!\xa4\x03\xc4' In python, I have successfully decompressed and re-compressed the data: b
