*OpenOCD compilation errors WITH SOLUTIONS*

[LarsKeuninckx]

Compiling OpenOCD (with gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0) as described in https://github.com/pulp-platform/pulpiss...l-platform, section "GDB and OpenOCD":

Code:

source sourceme.sh && ./pulp-tools/bin/plpbuild checkout build --p openocd --stdout

This error was encountered:

Code:

In function 'memset',
    inlined from 'mg_gen_ataid' at src/flash/mflash.c:1162:2,
    inlined from 'mg_storage_config' at src/flash/mflash.c:1174:2:
/usr/include/x86_64-linux-gnu/bits/string_fortified.h:71:10: error: '__builtin_memset' offset [509, 512] from the object at 'buff' is out of the bounds of referenced subobject 'reserved7' with type 'mg_io_uint8[186]' {aka 'unsigned char[186]'} at offset 322 [-Werror=array-bounds]

SOLUTION: see https://githubmemory.com/repo/STMicroele...OCD/issues, user nretro's comment:
 

  In src/flash/mflash.h the line

  

Code:

mg_io_uint8 reserved7[186];

 

  should be changed to

   

Code:

mg_io_uint8 reserved7[190];

This is obviously an error, since in mflash.c reserved7 is accessed using
    memset(pSegIdDrvInfo->reserved7, 0x00, 190);

    Current gcc compiler flags this with an out of bound warning. In combination with the "Werror" flag, the compilation will be aborted.

After fixing that error, this one appears:

Code:

In file included from src/helper/options.c:38:
/usr/include/x86_64-linux-gnu/sys/sysctl.h:21:2: error: #warning "The <sys/sysctl.h> header is deprecated and will be removed." [-Werror=cpp]
   21 | #warning "The <sys/sysctl.h> header is deprecated and will be removed."
      |  ^~~~~~~

SOLUTION: see https://github.com/rr-debugger/rr/commit...49d49cfe5d
Apply these changes  to pulp-sdk/tools/riscv-openocd/src/helper/options.c:

   

Code:

#if IS_DARWIN
    #include <libproc.h>
    #endif

    #include <sys/syscall.h>
    //#ifdef HAVE_SYS_SYSCTL_H
    //#include <sys/sysctl.h>
    //#endif

    #ifndef CTL_KERN
    #define CTL_KERN 1
    #endif
    #ifndef KERN_RTSIGMAX
    #define KERN_RTSIGMAX 33
    #endif

    (...)    
            char *path = malloc(PATH_MAX);
            if (path == NULL)
                break;
            int mib[] = { CTL_KERN, KERN_PROC, KERN_PROC_PATHNAME, -1 };
            size_t size = PATH_MAX;


            if (syscall(RR__sysctl, mib, (u_int)ARRAY_SIZE(mib), path, &size, NULL, 0) != 0)
            //if (sysctl(mib, (u_int)ARRAY_SIZE(mib), path, &size, NULL, 0) != 0)
                break;
     

Posted here so you don't have to waste the time we did. After that, the compilation works. Good luck.
