Building from source

Before attempting to build the extension, make sure the SAP NW RFC library is installed. See Installing the SAP NW RFC library for instructions.

Building on Linux

$ git clone
$ cd php7-sapnwrfc
$ phpize
$ ./configure
$ make
$ sudo make install

The build script looks for the SAP NW RFC library in the following locations by default:


If you installed the library in another location, replace the ./configure step above with ./configure --with-sapnwrfc=/path/to/rfc-library.

Building on Windows

We try to provide pre-built extensions for Windows users (see the release page). If you don’t find your desired version there or still want to build yourself, follow the instructions below.

Set up a build environment

Make sure you have a valid build enviroment as described here.

After you have set up the enviroment, try to build PHP itself:

$ configure --disable-all --enable-cli
$ nmake
$ nmake snap

If that works, you can go on. If not, double check your build environment.

Build the extension

Make sure that you dont mix up x86/x64 (PHP and SAP NW RFC library platforms must match).


  1. This guide assumes you want to build the x64 version.

  2. We also assume the SDK files are in C:nwrfcsdk

Copy all header files (*.h) from C:\nwrfcsdk\include to C:\php-sdk\phpdev\vc14\x64\deps\include. Copy all library files (*.lib) from C:\nwrfcsdk\lib to C:\php-sdk\phpdev\vc14\x64\deps\lib.

Download the latest release of this extension and extract it to C:\php-sdk\phpdev\vc14\x64\php-7.0-src\ext\sapnwrfc.

Open the Developer Command Prompt for VS2015 and execute the commands for steps 1-4 as described in the PHP Windows step by step build page.

The configure command (step 6) must be replaced with one of the following commands (depending on which version you want to build):

// for NTS (shared module)
configure --disable-all --enable-cli --disable-zts --with-sapnwrfc=shared
// for NTS (compile in)
configure --disable-all --enable-cli --disable-zts --with-sapnwrfc

// for TS (shared module)
configure --disable-all --enable-cli --with-sapnwrfc=shared
// for TS (compile in)
configure --disable-all --enable-cli --with-sapnwrfc

Then continue with steps 7-9.

If you built a shared extension, the extension files should be available in one of the following locations:

C:\php-sdk\phpdev\vc14\x64\php-7.0-src\x64\Release\php-7.0\ext for the NTS version
C:\php-sdk\phpdev\vc14\x64\php-7.0-src\x64\Release_TS\php-7.0\ext for the TS version
