Compile issue

[StefCoders]

Hi my rpi 3b is not working plus i have used issue 41's code and it still doesn't work !

here is the code:

cc -Wall -c mailbox.c
mailbox.c: In function ‘mapmem’:
mailbox.c:62:35: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
   62 |         printf("mmap error %d\n", (int)mem);

Same problem here, tried to add #include <sys/sysmacros.h> but no success.

Exactly same error, working with Rapi 3 B+

I have tried on 32bit OS but have similar error retrive , need help

[IgrikXD]

Fix:
Replace wrong code at line 270-271:

*vAddr = (void*)((uintptr_t)mbox.virt_addr + offset);
*bAddr = (void*)((uintptr_t)mbox.bus_addr + offset);

[Sergey-R5AU]

Thank you IgrikXD it`s working for me.

Just summary, my setup: RPI3

r5au@wspr:~/WsprryPi $ uname -a
Linux wspr 6.1.29-v8+ #1652 SMP PREEMPT Wed May 24 14:46:55 BST 2023 aarch64 GNU/Linux

I did moficitations:

1. Does not compile with gcc-8.3.0 #32 (comment) by damyan-ognyanov :
   added #include <sys/sysmacros.h> in mailbox.c before #include <sys/mman.h>
   and
   added -Wno-psabi to CXXFLAGS in project's makefile

2. Updated wspr.cpp with recommendations by IgrikXD

and finally:

R5AU: Your WSPR transmission as shown in your output only lasted for 81 seconds. WSPR transmissions should have a duration of 110.6 seconds to be decoded properly. I am seeing the same result with my RPI 3B+. Does anyone know what is causing the transmission to end after 81 seconds? Is there a fix to this problem? Thank you!
