These instructions only cover building grpc C and C++ libraries under |

typical unix systems. If you need more information, please try grpc's |

A typical unix installation won't require any more steps than running: |
|
|
|
$ make |
|
# make install |
|
|
|
You don't need anything else than GNU Make and gcc. Under a Debian or |
|
Ubuntu system, this should boil down to the following package: |
|
|
|
# apt-get install build-essential python-all-dev python-virtualenv |
|

Setting up dependencies |
|
======================= |
|
|
|
Dependencies to compile the libraries |
|
------------------------------------- |
|
|
|
grpc libraries have few external dependencies. If you need to compile and |
|
install them, they are present in the third_party directory if you have |
|
cloned the github repository recursively. If you didn't clone recursively, |
|
you can still get them later by running the following command: |
|
|
|
$ git submodule update --init |
|
|
|
Note that the Makefile makes it much easier for you to compile from sources |
|
if you were to clone recursively our git repository: it will automatically |
|
compile zlib and OpenSSL, which are core requirements for grpc. Note this |
|
creates grpc libraries that will have zlib and OpenSSL built-in inside of them, |
|
which significantly increases the libraries' size. |
|
|
|
In order to decrease that size, you can manually install zlib and OpenSSL on |
|
your system, so that the Makefile can use them instead. |
|
|
|
Under a Debian or Ubuntu system, one can acquire the development package |
|
for zlib this way: |
|
|
|
# apt-get install zlib1g-dev |
|
|
|
To the best of our knowledge, no distribution has an OpenSSL package that |
|
supports ALPN yet, so you would still have to depend on installing from source |
|
for that particular dependency if you want to reduce the libraries' size. |
|
|
|
The recommended version of OpenSSL that provides ALPN support is available |
|
at this URL: |
|
|
|
https://www.openssl.org/source/openssl-1.0.2-beta3.tar.gz |
|
|
|
|
|
Dependencies to compile and run the tests |
|
----------------------------------------- |
|
|
|
Compiling and running grpc plain-C tests dont't require any more dependency. |
|
|
|
|
|
Compiling and running grpc C++ tests depend on protobuf 3.0.0, gtest and |
|
gflags. Although gflags and protobuf are provided in third_party, you will |
|
need to manually install these dependencies on your system to run these tests. |
|
|
|
Under a Debian or Ubuntu system, you can install the gtests and gflags packages |
|
using apt-get: |
|
|
|
# apt-get install libgflags-dev libgtest-dev |
|
|
|
However, protobuf 3.0.0 isn't in a debian package yet: you'll need to compile |
|
and install it from the sources in the third_party. Note that if you already |
|
have the protobuf and protoc packages installed on your system, they will most |
|
likely interfere, and you'll need to uninstall them first. |
|
|
|
Compiling and installing protobuf 3.0.0 requires a few more dependencies in |
|
itself, notably the autoconf suite, curl, and unzip. If you have apt-get, you |
|
can install these dependencies this way: |
|
|
|
# apt-get install unzip curl autotools-dev |
|
|
|
Then, you can build and install protobuf 3.0.0: |
|
|
|
$ cd third_party/protobuf |
|
$ ./configure |
|
$ make |
|
# make install |
|
# ldconfig |
|
|
|
|
|
A word on OpenSSL |
|
----------------- |
|
|
|
Secure HTTP2 requires to have the TLS extension ALPN (see rfc 7301 and |
|
http://http2.github.io/http2-spec/ section 3.3). Our HTTP2 implementation |
|
relies on OpenSSL's implementation. OpenSSL 1.0.2beta3 is the first version |
|
of OpenSSL that has ALPN support, and this explains our dependency on it. |
|
|
|
Note that the Makefile supports compiling only the unsecure elements of grpc, |
|
and if you do not have OpenSSL and do not want it, you can still proceed |
|
with installing only the elements you require. However, it is recommended |
|
to encrypt your network traffic, therefore we urge you to not use the unsecure |
|
version of grpc if possible. |
|
|
|
|
|
Compiling |
|
========= |
|
|
|
If you have all the dependencies mentioned above, you should simply be able |
|
to go ahead and run "make" to compile grpc's C and C++ libraries: |
|
|
|
$ make |
|
|
|
|
|
Testing |
|
======= |
|
|
|
To build and run the tests, you can run the command: |
|
|
|
$ make test |
|
|
|
If you want to be able to run them in parallel, and get better output, you can |
|
also use the python tool we have written: |
|
|
|
$ ./tools/run_tests/run_tests.py |
|
|
|
|
|
Installing |
|
========== |
|
|
|
Once everything is compiled, you should be able to install grpc C and C++ |
|
libraries and headers: |
|
|
|
# make install
|
|
|
