Create native support for MSVC

[ben-crowhurst]

We've had a fair amount of success with Visual Studio 2015.

Hi,

We'd like to try the project on VS2015, is it possible to add support for this compiler?

Thanks,
Tim

This functionality has been in beta for sometime and should be available in the next week or two. Currently we're addressing the OpenSSL situation to help ease VS2015 integration.

Its now possible to build restbed in windows.

The build has been tested with Visual Studio 2015 Community Edition (compiler version 19.00.23026). You can use cmake to generate a VS project file or NMake files using the instructions below.

Examples that dont require OpenSSL, Syslog or PAM all build. The tests have not yet been ported. SSL support is not yet operational but this is just a matter of modifying cmake files to find the binaries on windows.

To create a Visual Studio project file, type the following at a command prompt or directly in GIT Bash (assuming cmake is in your path):

mkdir build && cd build
cmake -DBUILD_SSL=OFF -DBUILD_EXAMPLES=ON -G "Visual Studio 14 2015" ..

To use NMake, open a Visual Studio Command Prompt and navigate to restbed directory:

mkdir build && cd build
cmake -DBUILD_SSL=OFF -DBUILD_EXAMPLES=ON -DCMAKE_BUILD_TYPE=Release -G "NMake Makefiles" ..
nmake

The following helps to avoid the pain of opening the resource hog that is Visual Studio.

cmake -G "Visual Studio 14 2015" -DBUILD_SSL=NO -DBUILD_EXAMPLES=YES -DBUILD_TESTS=YES ..
cmake --build . --target ALL_BUILD --config Release
ctest

I can confirm that Restbed now builds natively on Windows with Visual Studio 2015. What follows is a set of instructions and any errors we have encountered along the way. I'm not going to close this ticket as several build warnings (unreachable code) still remain around test cases. These issues appear to be caused by our choice of framework.

Environment

• Windows 8.1 x64
• Visual Studio (CE) 14 2015

Setup
To address the resource problem and excessive file indexing caused by Visual Studio. We have opted to build the project using the Visual Studio 2015 x64 Native Tools Command Prompt. If your environment differs x86/ARM, please ensure you open the correct prompt. You MUST build Restbed and any dependencies (OpenSSL) via the same prompt to ensure x64 compatibility.

Once you've built the project and it's dependencies you can confirm you have the right build by checking each library as follows; they should produce matching output 8664 machine (x64) in our case.

dumpbin libeay32.dll /headers | findstr machine
dumpbin ssleay32.dll /headers | findstr machine
dumpbin restbed.lib /headers | findstr machine

Build OpenSSL
These instructions differ on x86/ARM platforms, please see dependency\openssl\INSTALL.* for details.

cd restbed\dependency\openssl
perl Configure VC-WIN64A
ms\do_win64a
nmake -f ms\ntdll.mak
nmake -f ms\ntdll.mak test
set PATH=restbed\dependency\openssl\out32dll;%PATH%

If you need to generate an SSL certificate you will additionally have to install OpenSSL.

nmake -f ms\ntdll.mak install
set PATH=%PATH%;c:\usr\local\ssl\bin

We will move to C:\tmp so the new certificate will work with the HTTPS example. The following must be performed in "Run As Administrator" mode to work, otherwise unable to write 'random state' errors will occur.

mkdir \tmp
cd \tmp
openssl genrsa -out server.key 1024
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt
openssl dhparam -out dh768.pem 768

Build Restbed

cd restbed
mkdir build
cd build
cmake -G "Visual Studio 14 2015 Win64" -DBUILD_EXAMPLES=YES -DBUILD_TESTS=YES ..
cmake --build . --target ALL_BUILD --config Release
ctest

While building OpenSSL with Visual Studio 2015 on Windows 10 we are getting this error. What was your build environment for compiling OpenSSL?

The static library is building fine : nmake -f ms\nt.mak

[ben-crowhurst]

@nViso If I recall correctly, this error was due to an OpenSSL build issue/bug. Please reset the OpenSSL folder to its original state.

Reset

cd restbed
git deinit -f dependency/openssl
git submodule update --init dependency/openssl

Confirm everything has reverted to its original state.

@nViso Alternatively I can make the shared library available to you via download?
