如何在没有root用户访问权限的Ubuntu上安装Google Test? [英] How to install Google Test on Ubuntu without root access?

问题描述

我试图根据此答案在没有root访问权限的Ubuntu上安装Google Test，因为我需要学习和使用它在工作.

I am trying to install Google Test according to this answer on Ubuntu without root access, as I need learn and use it at work.

设法在我自己的用户文件夹中完成这些操作:

Managed to get these done in my own user folder:

$ mkdir ~/temp
$ cd ~/temp
$ unzip gtest-1.7.0.zip 
$ cd gtest-1.7.0
$ mkdir mybuild
$ cd mybuild
$ cmake -DBUILD_SHARED_LIBS=ON -Dgtest_build_samples=ON -G"Unix Makefiles" ..
$ make

似乎我已经不想在/usr/src/gtest中使用gtest了，因为不是我安装了它，也不知道它的版本或可用性.未经允许，甚至无法删除它.

It seems I already have gtest in /usr/src/gtest altough I don't want to use this, because it was not me who installed it and I'm not sure about its version, nor in its availability. Can't even delete it without permission.

指令仍以以下方式结束:

Still the instruction ends as:

$ cp -r ../include/gtest ~/usr/gtest/include/
$ cp lib*.so ~/usr/gtest/lib

我在这里想念什么?

推荐答案

假设您要在/home/me/googletest中安装googletest.

Let's say you want to install googletest in /home/me/googletest.

浏览到googletest GitHub存储库https://github.com/google/googletest. (请勿使用您可能在其他地方获得的过时版本.)

Browse to the googletest GitHub repo https://github.com/google/googletest. (Do not use a possibly -out-of-date version you may have got elsewhere.)

使用克隆或下载链接进行克隆或下载并提取 来源为(例如)您当前目录CWD(其中CWD不是/home/me/)下的./googletest.

Using the Clone or Download link, either clone or download-and-extract the source as (let's say) ./googletest under your current directory CWD (where CWD is not /home/me/).

然后在CWD中:-

$ mkdir googletest_build
$ cd googletest_build
$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/home/me/googletest ../googletest
$ make
$ make install

在此之后，您将找到:-

After this, you will find:-

/home/me/googletest/
                lib/
                    libgmock.a
                    libgmock_main.a
                    libgtest.a
                    libgtest_main.a
                include/
                        gmock/
                            # gmock header files
                        gtest/
                            # gtest header files

然后您可以在源代码中使用gtest/gmock标头，例如:

You can then use gtest/gmock headers in your source code like:

#include <gtest/gtest.h>
#include <gmock/gmock.h>

并编译并链接gtest/gmock程序，例如:

and compile and link a gtest/gmock program like:

g++ -pthread -I/home/me/googletest/include -c -o my-unit-tester.o my-unit-tester.cpp
g++ -o my-unit-tester my-unit-tester.o -L/home/me/googletest/lib -lgtest -lgmock -pthread

使用-I...选项告诉编译器gtest/gmock标头位于何处，以及 使用-L...选项告诉链接程序gtest/gmock库在哪里.

using the -I... option to tell the compiler where gtest/gmock headers reside and using the -L... option to tell the linker where gtest/gmock libraries reside.

将-pthread传递给编译器和链接器，因为gtest/gmock库是 默认情况下建立多线程.

Pass -pthread to both compiler and linker because the gtest/gmock libraries are built multi-threading by default.

安装后，您不再需要CWD/googletest或CWD/googletest_build.

After installing you no longer need either CWD/googletest or CWD/googletest_build.

您可能希望将其他选项传递给cmake，在这种情况下，构建产品将根据这些其他选项的含义而有所不同.

You may wish to pass additional options to cmake, in which case the build products will differ as per the meaning of those additional options.
