open-license-manager/examples

Sample code that integrates open-license-manager

Licensecc

Copy protection, licensing library and license generator for Windows and Linux.

Protect the software you develop from unauthorized copies, limit the usage in time, to a specific set of machines, or prevent the usage in virtualized environments. It is an open source license manager that helps to keep your software closed 😏 . Among other features if it runs on a "real hardware" it can generate a signature of that hardware and report if the signature doesn't match.

A comprehensive list of features, and their status is available in the project site.

If you're experiencing problems, or you just need informations you can't find in the documentation please contact us on github discussions, we'll be happy to help.

Remember to show your appreciation giving us a star here on GitHub.

License

The project is donated to the community. It comes with freedom of use for everyone, and it always will be. It has a BSD 3 clauses licensing schema, that allows free modification and use in commercial software.

Project Structure

The software is made by 4 main sub-components:

• a C++ library with a nice C api, licensecc with minimal (or no) external dependencies (the part you have to integrate in your software) that is the project you're currently in.
• a license debugger lcc-inspector to be sent to the final customer when there are licensing problems or for calculating the pc hash before issuing the license.
• a license generator (github project lcc-license-generator) lccgen for customizing the library and generate the licenses.
• Usage examples to simplify the integration in your project.

How to build

Below an overview of the basic build procedure, you can find detailed instructions for Linux or Windows in the project web site.

Prerequisites

• Operating system: Linux(Ubuntu, CentOS), Windows
• compilers : GCC (Linux) MINGW (Linux cross compile for Windows), MINGW or MSVC (Windows)
• tools : cmake(>3.6), git, make/ninja(linux)
• libs : If target is Linux Openssl is required. Windows depends only on system libraries. Boost is necessary to build license generator and to run the tests but it's NOT a dependency of the final licensecc library.

For a complete list of dependencies and supported environments see the project website

Clone the project. It has submodules, don't forget the --recursive option.

git clone --recursive https://github.com/open-license-manager/licensecc.git
cd licensecc/build

build on Linux

cmake .. -DCMAKE_INSTALL_PREFIX=../install

build on Windows (with MSVC 2017)

cmake .. -G "Visual Studio 15 2017 Win64" -DBOOST_ROOT="{Folder where boost is}" -DCMAKE_INSTALL_PREFIX=../install
cmake --build . --target install --config Release

cross compile with MINGW on Linux

x86_64-w64-mingw32.static-cmake .. -DCMAKE_INSTALL_PREFIX=../install
make
make install

How to test

on Linux

make test

on Windows (MSVC)

ctest -C Release

How to use

The examples repository that shows various ways to integrate licensecc into your project.

How to contribute

The easiest way you can solve your problems or ask help is through the discussions tab above, otherwise if you think there is a problem you can open an issue in the issue system. Have a look to the contribution guidelines before reporting. We use GitFlow (or at least a subset of it). Remember to install the gitflow git plugin and use develop as default branch for your pull requests.

Using licensecc in C projects

Please add C examples for using licensecc.

how to obtain the signature of the hardware?

hi, I want to use the command "bin/lccgen license issue -s [ --client-signature ] ..."，
but I don't know how to get the signature of the hardware?

examples project - integration with travis

Prepare a .travis.yml for examples project to check they're always buildable

submodule/src/example.cpp: errors in identify_pc

In the example file https://github.com/open-license-manager/examples/blob/develop/submodule/src/example.cpp
size_t pc_id_sz = LCC_API_PC_IDENTIFIER_SIZE;
should be modified to
size_t pc_id_sz = LCC_API_PC_IDENTIFIER_SIZE + 1;
or identify_pc will fail and print errors in identify_pc. It won't output the pc signature.

how to obtain the signature of the hardware？

hi, I want to use the command "bin/lccgen license issue -s [ --client-signature ] ..."，
but I don't know how to get the signature of the hardware?

I need your help to use examples.

I downloaded licensecc and finished installing it.
I also completed the test without any problems.
but i got a problem to follow the examples.
I installed "open-license-manager" in the "C:\code-lock\open-license-manager" path.
when I follow "simple-pc-identifier" in examples, an error occurred.
"export LCC_INSTALLATION_DIR = ... #folder where you installed open-license-manager ¹" in this process
I set "set LCC_INSTALLATION_DIR=C:\code-lock\open-license-manager" and go build and start cmake
when the cmake start, an error occured.
The error is as follows.

-- Selecting Windows SDK version 10.0.18362.0 to target Windows 10.0.18363.
CMake Error at CMakeLists.txt:16 (find_package):
By not providing "Findlicensecc.cmake" in CMAKE_MODULE_PATH this project

"licensecc", but CMake did not find one.
Could not find a package configuration file provided by "licensecc"
(requested version 2.0.0) with any of the following names:

Add the installation prefix of "licensecc" to CMAKE_PREFIX_PATH or set
"licensecc_DIR" to a directory containing one of the above files. If
"licensecc" provides a separate development package or SDK, be sure it has
been installed.

Installation problem on Windows

Hello,
I tried to install open-license-manager on Windows with MSVC 2019.
I chose the "Compile and Build (command line)" way to do it.
I retrieved the code from Github and followed the steps written in the documentation.
When I launch "cmake --build . --target install --config Release", I got the following error:

Why do I encounter this message?

To circonvent the problem, I launched the "licensecc.sln" file located in the build folder and compiled in Visual Studio. Is it a valid solution? I am not very confident since I encountered subsequent problems to launch the examples then.

Any help would be appreciated.

I do not get the message `"MY_AWESOME_FUNC is licensed" : what am I doing wrong?
