我正在尝试在Ubuntu 10.04下编译Android源代码.我收到一个错误说,

/ usr/bin/ld:找不到-lz

你能告诉我怎么解决它？什么cannot find -lz意思？这是完整的错误消息:

external/qemu/Makefile.android:1101: warning: overriding commands for target `external/qemu/android/avd/hw-config-defs.h'
external/qemu/Makefile.android:933: warning: ignoring old commands for target `external/qemu/android/avd/hw-config-defs.h'

我的GCC版本输出:

打印由ld按其搜索顺序查看的搜索路径的方法是什么.

我试图Boost在我的项目中包含库,并且一直面临着相同的问题.我在使用Codeblocks IDE的Ubuntu 12.10上,尝试手动从站点读取指令来安装库,但是在使用头文件以及使用前构建的库时出现了错误.

然后我通过terminalby安装了库sudo apt-get install libboost-all-dev.在此之后,在我的Codeblocks程序中,我可以包含标题,#include <boost/regex.hpp>但是当我尝试包含Filesystem库(#include "boost/filesystem/operations.hpp" )的标题时,我收到以下错误:

/usr/include/boost/system/error_code.hpp|214|undefined reference to boost::system::generic_category()'|

我不知道如何解决此错误(特别是在Linux上的Codeblocks中).我真的可以在这里使用一些帮助.

编译器:Gcc
程序代码:仅尝试包含上述文件系统operations.hpp文件.

从Codeblocks构建日志:

我在ubuntu 12.04上安装pyipopt时遇到问题.在链接期间,我收到错误:

/usr/bin/ld: cannot find -lcoinhsl

即使我知道已安装此库,并且可以使用.so和.la文件 /home/mostafa/MyBuilds/CoinIpopt/build/lib/

有没有人有这个解决方案？

下面是运行setup.py build的完整返回:

我有一个单一的.RS文件。当我编译它时rustc test1.rs，我收到一个错误：

我最近不得不在Ubuntu系统上做一些小编程(我是一个非常低级的初学者)而且我真的只是熟悉makefile.

我注意到告诉链接器要包含哪些库的参数总是-l {library name},其中相应的库在/ usr/lib文件夹中称为"lib {library name} .a".

我想知道:这是一个会议吗？我原以为我需要输入-llibNAME来查找一个名为libNAME.a的库,但它似乎假设一个lib前缀.

总是这样吗？我可以在不使用lib前缀的情况下命名库吗？

我将首先说我是gcc和makefile的新手.我在桌面(〜/桌面)上有一个.so文件lib.so.我想将我的程序(称为myProgram)链接到它.我在makefile中写的是:

g++ myProgram.o -L ~/Desktop -l lib -o myProgram

当我跑步时,make我得到一个错误:

/usr/bin/ld: cannot find -llib

我也试过-l lib.so并得到了同样的错误.链接的正确方法是什么？

我正在尝试将开源库libsndfile与 Android NDK 交叉编译。我的主机是 Windows 10 下的 Ubuntu 子系统，目标是 Android 系统（目前任何人都会这样做）。对于构建，我使用 autogen+configure 设置，如 libsndfile文档中所述。编译在链接阶段停止，生成一个冗长的日志文件（略多于 400 行），其中包含多个错误。开始时的错误似乎并不重要，但请配置探测编译器设置，如 本文所述。最后一条错误消息指向链接器问题。我认为这是日志文件的相关摘录：

我似乎无法在我的amazon linux服务器上安装任何R软件包,在EC2上运行.这是一个尝试安装"扫帚"包的简单示例.知道这里发生了什么吗？任何帮助将不胜感激,因为我已经坚持了约5个小时.我已经粘贴了下面的所有控制台输出.

我已经查看了usr/bin/ld:cannot find -l<nameOfTheLibrary>中的答案，但它们都不适用于此上下文。

我刚刚买了一台新笔记本电脑并设置了 Go。一个简单的 hello world 程序可以工作，但是当我尝试一个更复杂的程序时，我得到：

go run .

/usr/bin/ld: cannot find -lavcodec
/usr/bin/ld: cannot find -lavformat
/usr/bin/ld: cannot find -lavutil
