The product compilation references wxWidgets libraries using WXWIN environment variable. Please set it to wxWidgets folder (i.e. C:\SDK\wxWidgets).
In order to have the build process digitally sign output files, one should provide the following:
- A signing certificate installed in the current user’s certificate store.
- The following variables in the environment:
ManifestCertificateThumbprint- set the value to certificate’s SHA1 thumbprint (hexadecimal, without spaces, i.e.bc0d8da45f9eeefcbe4e334e1fc262804df88d7e).ManifestTimestampRFC3161Url- set the value to URL used to perform RFC3161 timestamp signature (i.e.http://sha256timestamp.ws.symantec.com/sha256/timestamp). In order to perform timestamp signing successfully, the computer running the build should be online and able to access this URL.
Please note that only Release builds are configured for timestamp signing. Debug configurations do not attempt to timestamp sign the resulting DLL and EXE files in order to speed up the building process and enable offline building.
This product has some submodules. When cloning Git repository, make sure to use --recursive Git switch to clone submodules too. Example:
git clone --recursive "https://github.com/Amebis/GEANTLink.git" "C:\Projects\GEANTLink"
After clone is complete, grant Users local group read and execute permissions to output subfolder (when working folder is private). This allows EapHost service to load DLL, and Event Viewer to display events.
The product can be build and debugged opening GEANTLink.sln in Visual C++ IDE.
Before one can attempt to debug EAP DLLs, you should run nmake register from an elevated command prompt. See Building in command line chapter below.
Next, one must configure a network profile to actually use one of this product's EAP modules for the authentication.
EAP modules are divided into two DLLs: backend (i.e. EAP-TTLS.dll) and GUI (i.e. EAP-TTLS_UI.dll).
The backend DLL is loaded by Eap3Host.exe process when connecting to the network. One approach to debug the module is to start Visual C++ elevated, open GEANTLink.sln, and attach to the running Eap3Host.exe process.
On initial connection attempt Eap3Host.exe will load the DLL and will not release it until EapHost service is restarted. To release our DLL (i.e. for rebuild) you have to restart EapHost service manually or run nmake register again.
To debug early life of our backend DLL, uncomment Sleep(10000) in DllMain() of the module, and set breakpoints. This should give you plenty of time to catch emerging Eap3Host.exe process and attach the debugger to it before our DLL starts servicing authentication.
The GUI DLL is loaded by DllHost.exe process on XML profile configuration import/export and when interactive user interface is required.
A few seconds after desired function call has finished, DllHost.exe terminates and releases the DLL.
To debug early life of our GUI DLL, uncomment Sleep(10000) in DllMain() of the module, and set breakpoints. This should give you plenty of time to attach the debugger to DllHost.exe process before our DLL starts.
Open Developer Command Prompt for VS 2019 for building.
Use Microsoft NMAKE to build the project.
| Command | Explanation |
|---|---|
nmake Clean |
Deletes all intermediate and output files. |
nmake Register |
Builds a debug version of project, registers DLLs, and adds Start Menu shortcuts. For testing and development purposes only! Requires elevated command prompt. |
nmake Unregister |
Removes Start Menu shortcuts, unregisters DLLs. For testing development purposes only! Requires elevated command prompt. |
nmake Setup |
Builds a release version of project and release MSI setup files. The resulting files can be found in output\Setup folder. |
nmake SetupDebug |
Builds a debug version of project and debug MSI setup files. The resulting files can be found in output\Setup folder. |
The /ls flag can be appended to the commands above to reduce NMAKE’s verbosity. You can combine multiple targets (i.e. nmake Unregister Clean). Please, see NMAKE reference for further reading.
