13. Building with CMake
|
||||
Note: Primary development uses automake (./configure). The support for CMake is minimal.
|
||||
|
||||
Internally cmake is setup to do the following:
|
||||
1. Uses the ./configure generated wolfssl/options.h as the build options by coping it to the build directory as user_settings.h.
|
||||
2. Builds wolfSSL as library.
|
||||
3. Builds the examples.
|
||||
|
||||
Build Steps:
|
||||
$ mkdir build
|
||||
$ cd build
|
||||
$ cmake ..
|
||||
$ cmake --build .
|
||||
$ cmake --install .
|
||||
|
||||
To build library only and not build examples and test apps use:
|
||||
$ cmake .. -DBUILD_TESTS=NO
|
||||
|
||||
To build with debugging use:
|
||||
$ cmake .. -DCMAKE_BUILD_TYPE=Debug
|
||||
|
||||
Make sure and run the built examples and test from the wolfssl-root to properly find the ./certs directory.
|
||||
|
||||
CMake on Windows with Visual Studio
|
||||
1. Open Command Prompt
|
||||
2. Run the Visual Studio batch to setup command line variables: Example: C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat
|
||||
3. Then use steps above
