错误：未满足包要求（libprotobuf-c> = 1.0.1）

Question

我正在使用GitHub的protobuf-c。当我运行make时会发生此错误。

$ git clone https://github.com/protobuf-c/protobuf-c.git
Cloning into 'protobuf-c'...
$ cd protobuf-c
$ ./autogen.sh
...

然后：

$ ./configure
...

checking whether g++ supports C++11 features with -std=c++11... yes
checking for protobuf... no
checking for protobuf... no
configure: error: Package requirements (libprotobuf-c >= 1.0.1) were not met:
No package 'libprotobuf-c' found

Consider adjusting the `PKG_CONFIG_PATH` environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables `libprotobuf_c_CFLAGS`
and `libprotobuf_c_LIBS` to avoid the need to call pkg-config.
See the pkg-config man page for more details.
make: *** [config.status] Erreur 1

有什么问题，我该如何解决？

如何解决有关libprotobuf-c的配置错误？ configure：error：未满足包需求（libprotobuf-c> = 1.0.1）...

确保已安装这些先决条件。 README.md没有列出它们。

Ubuntu的软件包是：

• libprotobuf-dev的
• libprotoc-dev的
• protobuf的编译

Fedora的软件包是：

• protobuf的-devel的
• protobuf的编译

如果您缺少libprotobuf-dev，那么您会收到错误：

configure: error: Package requirements (protobuf >= 2.6.0) were not met...

如果您缺少libprotoc-dev，那么您会收到错误：

checking for google/protobuf/compiler/command_line_interface.h:
configure: error: required protobuf header file not found

如果您缺少protobuf-compiler，那么您会收到错误：

configure: error: Please install the protobuf compiler from
https://code.google.com/p/protobuf/

安装了prereq后，您应该使用以下摘要成功配置：

configure: creating ./config.status
config.status: creating Makefile
config.status: creating protobuf-c/libprotobuf-c.pc
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing depfiles commands
config.status: executing libtool commands
