9.2i EDK - Errors when compiling Xilkernel 4.00a with mb-g++ compiler


Keyword: Xilkernel, G++, compiler, error, C++, gcc, GNU

When I run Generate Libraries and BSP, and use the C++ compiler instead of the C compiler, I get many error messages.

Errors like :
- using void pointers in mathematical expressions popup,and indeed the compiler is not lying! The QUEUE works probably fine because the basic type is a CHAR, but the void pointer is incremented with 1 and not with the actual type-size.
See QUEUE.C line 115 :
memcpy (( queue->items+(qend*queue->item_size)),item,queue- >item_size);

- also function prototypes are not always correct, see sched.c , where
The restore_context() function has a prototype with zero arguments (whoch should be the process structure pointer), using the C compiler this will be slipped trough !

- other messages like
main.c:112: error: 'hw_init' was not declared in this scope
main.c:128: error: 'pthread_init' was not declared in this scope
main.c:131: error: 'sem_heap_init' was not declared in this scope
main.c:172: error: 'microblaze_enable_interrupts' was not declared in this
are result of missing prototypes.


As a workaround, please modify the Makefiles at <EDK92_install>\sw\lib\bsp\xilkernel_v4_00_a\src as follows:





This problem has been fixed in the latest EDK 9.2i Service Pack, available at:
The first service pack containing the fix is EDK 9.2i Service Pack 2.
