sorry, previous email sent by mistake. #include "sys/socket.h" actually solved the problem instead of only "socket.h" many thanks.

camkes error.h include problem
by yogidk . 14 Jun '19

Hi , I have a test_1.c file which includes <camkes.h> camkes.h which is automatically generated has following includes #include <camkes/dataport.h> #include <camkes/error.h> #include <stdint.h> #include <stdlib.h> #include <utils/util.h> #include <platsupport/io.h> and another file test_2.c which includes "socket.h" In CMakeLists.txt, where I compile my test_1.c and test_2.c looks like this DeclareCAmkESComponent(test INCLUDES "../muslibc/include/sys"* // necessary for compilation as test_2.c has "socket.h"* SOURCES "test_1.c" "test_2.c" C_FLAGS -Wall -Werror LIBS seos_libs ) However when I compile , I start getting these errors: In file included from ../projects/util_libs/libplatsupport/include/platsupport/io.h:20:0, from projects/test/include/camkes.h:20, from ../projects/src/test_1.c:8: ../projects/musllibc/include/sys/errno.h:1:2: error: #warning redirecting incorrect #include <sys/errno.h> to <errno.h> [-Werror=cpp] *#warning redirecting incorrect #include <sys/errno.h> to <errno.h>* ^~~~~~~ In file included from ../projects/musllibc/include/sys/errno.h:2:0, from ../projects/util_libs/libplatsupport/include/platsupport/io.h:20, from projects/test/include/camkes.h:20, from ../projects/src/test_1.c:8: ../projects/musllibc/include/sys/errno.h:1:2: error: #warning redirecting incorrect #include <sys/errno.h> to <errno.h> [-Werror=cpp] #warning redirecting incorrect #include <sys/errno.h> to <errno.h> How could this be solved ? thanks --yk

Re: [seL4] xilinx ultrascale+: Spurious interrupt
by Shen, Yanyan (Data61, Kensington NSW) 05 Jun '19

Hi Leonid, One possible cause I can think of is the trigger type (level vs edge) of an interrupt is incorrect. The Linux device tree should have interrupt type for each interrupt source, so you can change the GIC init code to configure the interrupt types (GICD_ICFGR, assuming GICv2) accordingly and see if the messages disappear.

Hello Sel4 developer, Thanks for your support. Aditya and me are debugging physical memory sel4. Is there visual tool or analysis module or anything to debugging that physical memory to virtual mapping table. If you have any question, please let me know. BR, MK
