Google protobuf in Linux

提问by Max Frai

I'm working with protobuf and Linux. Where is its compiler protoc. I've downloaded package from main site, compiled and installed it successfully but I can't find protocto build my own format file. Where is it?

我正在使用 protobuf 和 Linux。它的编译器在哪里protoc。我已经从主站点下载了软件包，编译并成功安装了它，但我找不到protoc构建自己的格式文件。它在哪里？

UPDATEHere is folder where I built protobuf:

更新这是我构建 protobuf 的文件夹：

There isn't binary file I need.

没有我需要的二进制文件。

It's probably installed into /usr/local/bin

它可能已安装到 /usr/local/bin

On Ubuntu at least, you can apt-get install protobuf-compilerinstead.

至少在 Ubuntu 上，你可以apt-get install protobuf-compiler代替。

From the INSTALL.txt:

从 INSTALL.txt：

Installation Names

By default, 'make install' will install the package's files in '/usr/local/bin', '/usr/local/man', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PATH'.

安装名称

默认情况下，'make install' 会在 '/usr/local/bin'、'/usr/local/man' 等目录中安装包的文件。你可以通过给出 '配置'选项'--prefix = PATH'。

Also, if you are in fact on Ubuntu, then you can also fetch the source package from Debian unstable and rebuild them locally if you want packages that are more current than the last cutoff (which for Ubuntu 9.10 was some time late last summer). That way you end up with .deb packages and you preserve a normal upgrade path (rather than littering /usr/local with one-off installs).

此外，如果您实际上使用的是 Ubuntu，那么如果您想要比上次截止日期（对于 Ubuntu 9.10 是去年夏末的某个时间）更新的软件包，您还可以从 Debian 不稳定版获取源代码包并在本地重建它们。这样，您最终会得到 .deb 包并保留正常的升级路径（而不是一次性安装乱扔垃圾 /usr/local）。

First, you need to compile you source code from protobuff (in the root folder):

首先，您需要从 protobuff（在根文件夹中）编译源代码：

./configure  
make   
make check   
make install

Second:

第二：

echo "/usr/local/lib">>/etc/ld.so.conf  
echo "/usr/lib">>/etc/ld.so.conf    
ldconfig

Third:

第三：

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

Read README.txt in root folder for more info.

阅读根文件夹中的 README.txt 以获取更多信息。

Actually you don't need to know it's place. All you want is to open terminal where your proto file is located and write at terminal

其实你不需要知道它的位置。您只需要打开 proto 文件所在的终端并在终端写入

protoc -I=. --cpp_out=. filename.proto

You can find protoc in the path which you set ./configure --prefix=you_path. When you make install successful, it will general bin, include and lib in that path.

您可以在您设置的路径中找到 protoc ./configure --prefix=you_path。当您安装成功时，它将在该路径中通用 bin、include 和 lib。
