CPP-REST-SDK in Centos 7

Question

I have a CentOS 7 (EPEL-Repo is registered) but I do not find the package for CPP-REST (libcpprest-dev in Debian) in the repos.

Do I need to install it from vanilla or is there a package in CentOS?

Thanks!

Short answer...

There is not an "official" CentOS 7 package at this time (2018-10-03) for cpprestsdk (libcpprest-dev in Debian).

Long answer (sharing this in case it helps anyone)...

You could build cpprestsdk from source, but the instructions "How to build for Linux" (https://github.com/Microsoft/cpprestsdk/wiki/How-to-build-for-Linux) do not include CentOS or RHEL (at the time of this writing, 2018-10-03).

Before building cpprestsdk on CentOS 7, you'll need to update boost (at time of this writing CentOS 7 repos have boost 1.53, but 1.54 is required, and 1.68 is latest). You can do this to update (using boost 1.68 as example):

cd && wget https://dl.bintray.com/boostorg/release/1.68.0/source/boost_1_68_0.tar.gz
tar -xzvf boost_1_68_0.tar.gz
cd ~/boost_1_68_0
./bootstrap.sh --prefix=/opt/boost
sudo ./b2 install --prefix=/opt/boost --with=all

After updating boost, I was able to build cpprestsdk on CentOS 7 like this...

Install some needed tools/libraries:

sudo yum -y install git cmake3 openssl-devel gcc-c++ make

Download the cpprestsdk project:

git clone https://github.com/Microsoft/cpprestsdk.git casablanca

cpprestsdk wants to treat warnings as errors. I had to turn this off by commenting out this line in ~/casablanca/Release/CMakeLists.txt:

#set(WERROR ON CACHE BOOL "Treat Warnings as Errors.")

Prepare/build cpprestsdk project:

cd casablanca/Release
mkdir build.release && cd build.release
cmake3 .. -DCMAKE_BUILD_TYPE=Release -DBOOST_ROOT=/opt/boost
make

Install header files and library

sudo make install

Notice that I am calling cmake3 (not cmake) and I am specifying the boost root; which differs from the official instructions that appear to be written and tested for Ubuntu (not CentOS or RHEL). To build my projects using cpprestsdk, I had to use ldconfig to find the library paths.
