Hi Adrian,
Thank you for your explanation. But I am still a little confused. If a C++ program uses standard library, then both standard library C++ library and C library are needed, right? And in sel4, you have ported a standard library C library (muslc), but you do not port any standard library C++ library to sel4. Is this correct? I know some standard library C library, such as glibc or muslc, but I do not know any standard library C++ library. Could you give me suggestion which C++ library may easy to port?
In additon, you said that you had some success with using your native gcc C++ libraries for compilation. Do you mean you link C++ program with Linux native C++ library first, and then link it to C library in sel4?
Thanks a lot!. Yuxin

The seL4 kernel itself does not need anything for running C++ support. However, a version of the C++ standard library would need to be ported / implemented to a particular seL4 environment. If you would like to compile C++ code that does not use the standard library then this relatively easy and there is a trivial example in sel4test (see https://github.com/seL4/sel4test/blob/master/apps/sel4test-tests/src/tests/d... and https://github.com/seL4/sel4test/blob/master/apps/sel4test-tests/Makefile)
I had some success with using my native gcc C++ libraries for compilation, although it was a little fiddly to make work. The idea there is that since the C++ standard libraries depend upon the syscalls and other symbols defined in the C library you can just link against your native C++ libraries, and rely on the ported C library (in our case muslc) to implement the syscalls and make everything work. I am not promoting this as a good idea or a way to build a reliable system, but might give you a bit of insight into what is required for a proper C++ port.

Hi,
Can I run C++ programs on sel4? I am not familiar with programming language. I do not know the relationship between the OS and the C++ language. In order to run C++, does the OS need to provide some support or what user level library are needed?
Thanks a lot. Yuxin
