Chroutine

image image image

With Chroutine, you can easily develop highly concurrent programs in C++ and write code with synchronization semantics.

Usage

Create a chroutine is very simple:

ENGIN.create_chroutine([](void *){
    while (1) {
        SPDLOG(INFO, "hello Chroutine 1, looping");
        SLEEP(1000);
    }
}, nullptr);

ENGIN.create_chroutine([](void *){
    SPDLOG(INFO, "hello Chroutine 2");
    SLEEP(1000);
    SPDLOG(INFO, "hello Chroutine 2, exit now");
}, nullptr);

You can also run the examples and see the code to learn more:

$ cd examples/build
$ ./configure.sh
$ cd build
$ make

Install

my platform

  • CentOS Linux release 7.4.1708, x86_64
  • gcc (GCC) 4.8.5 20150623

install grpc (if you need the RPC module)

my system: CentOS Linux release 7.4.1708

get ready

sudo yum install autoconf automake autogen libtool shtool build-essential pkg-config libgflags-dev libgtest-dev clang libc++-dev

build and install

git clone https://github.com/grpc/grpc
cd grpc
git submodule update --init
make
[sudo] make install

error and solution

if get configure error:

configure in doc/example fails with "cannot find install-sh, install.sh, or shtool in "." "./.." "./../..""

try:

cd third_party/protobuf
autoreconf -i -v -f

git submodule update --init will download third party code, try to download yourself and put them in right place if failed in China:

install protoc

it was build but not installed:

cd third_party/protobuf
sudo make install

try to generate protobuf code

cd proto_def
sh gen.sh test.proto

You should see four files:

├── proto_code
│   ├── test.grpc.pb.cc
│   ├── test.grpc.pb.h
│   ├── test.pb.cc
│   └── test.pb.h

install libcurl (if you need the http client module)

curl.git
