Musa.Runtime is available, ucxxrt is no longer providing support!!!
UserMode support has been removed since March 29th, 2022. The final version known to support UserMode is e2f159f8f. Please use VC-LTL5 instead in UserMode.
ucxxrt is an open source runtime library based on MSVC. The highlight of this project is its usability in kernel-mode drivers, and it provides you nearly the same experience as developing user-mode applications in C++.
Before ucxxrt was born, in order to use C++ STL in kernel-mode drivers, users have to craft their own template libraries (eg. KTL, ustd, ...).
There are still several problems. Like it does not support C++ exceptions, and mainly, it costs very much time to implement new language features when C++ ISO standard updates.
Then ucxxrt was born.
-
When developing kernel-mode drivers, kernel-mode flag is disabled by using property sheets, forcibly making the compiler support C++ exceptions. Exception flag(
/EHsc) is also enabled. -
Implements exception functions like
throw,catch. Simulates the exception dispatcher inthrowand handles the exception in callback functions.
- support x86, x64, ARM(experimental), ARM64(experimental).
- support new/delete operators.
- support C++ exception (/EHa, /EHsc).
- support SAFESEH、GS (Buffer Security Check).
- support STL (not fully).
- support static objects.

}First, rename DriverEntry to DriverMain.
Right click on the project, select "Manage NuGet Packages".
Search for ucxxrt, choose the version that suits you, and then click "Install".
-
Download the latest package from Releases and unzip it.
-
Add the property sheet
ucxxrt.propsto your project.
IDE：Visual Studio 2022 latest version
and Windows SDK
and Windows Driver Kits
-
git clone --recurse-submodules https://github.com/MiroKaku/ucxxrt.git -
Open
ucxxrt.slnand build. -
For clang-cl or llvm-msvc, you will have to add
-march=nativein the compiler flags.
Thanks to JetBrains for providing free licenses such as Resharper C++ for my open-source projects.
Great thanks to these excellent projects. Without their existence, there would be no
ucxxrtthen.
