Hi,
I’m trying to cross compile my sample application code which is written in c for ARM target using pepper_63 toolchain downloaded from samsung developer site.
But, while cross compiling the source with my make file, i’m seeing lot of issues
- Predefined macros like unix, unix, __unix etc are unavailable which is causing compilation issues.
- Getting lot of warnings for system functions like socket, connect etc.
[root@localhost pepper_63]# toolchain/linux_arm_glibc/bin/arm-nacl-gcc -g -o SAM server.c
/tmp/ccVJDzPF.o: In function `main’:
/home/arisanka/tizen/pepper_63/server.c:51: warning: accept is not implemented and will always fail
/home/arisanka/tizen/pepper_63/server.c:40: warning: bind is not implemented and will always fail
/home/arisanka/tizen/pepper_63/server.c:46: warning: listen is not implemented and will always fail
/home/arisanka/tizen/pepper_63/server.c:59: warning: send is not implemented and will always fail
/home/arisanka/tizen/pepper_63/server.c:29: warning: setsockopt is not implemented and will always fail
/home/arisanka/tizen/pepper_63/server.c:22: warning: socket is not implemented and will always fail
i don’t know what this warning means. I could see the symbols for these system functions are present in the libc.so for the target
[root@localhost pepper_63]# toolchain/linux_arm_glibc/bin/arm-nacl-readelf -a toolchain/linux_arm_glibc/arm-nacl/lib/libc-2.23.so | grep socket

#include <netpacket/packet.h>
I can see the headers present in x86 target but not for ARM
[root@localhost pepper_63]# find . -name packet.h
./toolchain/linux_x86_glibc/x86_64-nacl/include/netpacket/packet.h
./toolchain/win_x86_glibc/x86_64-nacl/include/netpacket/packet.h
./toolchain/mac_x86_glibc/x86_64-nacl/include/netpacket/packet.h
./include/nacl_io/socket/packet.h
Appreciate any help or support on this.
