Some of the compiler flags that affect code generation may cause stack unwinding to fail. You need to compile these files as C-files, while (most of) the rest of your kernel is C++ Note that you should *NOT* rename any source files from. If you don't need multi-thread support, change it to #include 'gthr-single.h' There is a generated file 'gthr-default.h', most of the time it contains only one line: #include 'gthr-posix.h'.

Try to compile these source files, if any header file is missed, search GCC source tree and build tree for it.

Copy the source files into your kernel source tree except emutls.c(it's unnecessary), and add necessary compiler flags recorded in last step.

Check the console output and find out the exactly source files and compiler flags needed for libgcc_eh.

Type command 'make -k libgcc_eh.a' and record the console output of this command.

Change to the sub-directory libgcc under the directory mentioned above.

In the GCC build tree, you can find a directory named the same as your GCC target, e.g.

First thing is to try to cross compile GCC (you will fail, don't worry).

Then copy all the source files and header files into your own kernel source tree and compile them with your existing build system, no special compiler flags are needed. If you don't need multi-thread support in your kernel (no smp, kernel code isn't preemptive), create some pthread stubs. It depends on a few simple libc functions and a few pthread functions. If you still can't compile libcxxrt or libgcc_eh, find a copy of the corresponding header file from a unix system and find out exactly what you are missing. If you don't have any of the unix header files when compiling libcxxrt or libgcc_eh, e.g. The major reason you may want libunwind instead of libgcc_eh is that libgcc_eh is licensed under LGPL. libunwind is more difficult to port, it depends on pthread and some type definitions in and. For the unwind library part, you have two options, libunwind and libgcc_eh. I prefer the second option, because libsupc++ is part of GCC, it's even not trivial to compile it separately. So, in order to add C++ exception support, you just need to port the second and the third layer into you kernel, which means you need to either port libsupc++ or port libcxxrt and an unwind library. BTW, the second layer also adds support for RTTI & dynamic_cast All the dirty work are done by the third layer: the unwind library. For exception support this layer is more or less a wrapper around the third layer. The compiler translates the 'try' 'catch' 'throw' statements into calls to specific functions in C++ runtime. In the ABI, C++ exception is supported by the cooperation of three layers.
