errors compiling ministrace

[aax68]

I had fun reading you blog about ministrace. I tried to compile it but end up with errors.

Could you take a look please?

root@oracle1 ministrace]# make
./gen_tables.py /usr/src/linux/
Traceback (most recent call last):
File "./gen_tables.py", line 109, in ?
sys.exit(main(sys.argv[1:]))
File "./gen_tables.py", line 104, in main
syscall_numbers = do_syscall_numbers(os.path.join(linux_dir, unistd_h))
File "./gen_tables.py", line 9, in do_syscall_numbers
for line in open(unistd_h):
IOError: [Errno 2] No such file or directory: '/usr/src/linux/arch/x86/include/asm/unistd_64.h'
make: *** [syscallents.h] Error 1
[root@oracle1 ministrace]# uname -a

if it helps, this is what I have for unistd on the system

Thank you

You need to modify the python file.

def main(args):
    if not args:
        print >>sys.stderr, "Usage: %s /path/to/linux-2.6" % (sys.argv[0],)
        return 1
    linux_dir = args[0]
    if os.uname()[4] == 'x86_64':
        unistd_h = "asm/unistd_64.h"
    else:
        unistd_h = "asm/unistd_32.h"
 
    syscall_numbers = do_syscall_numbers(os.path.join(linux_dir, unistd_h))
    syscall_types   = find_args(linux_dir)
    write_output('syscallents.h', syscall_types, syscall_numbers)

Please note that python is white space sensitive

Finally, change LINUX_SRC= in the Makefile to /usr/include

I think in your case, you should change asm/unistd_64.h to asm-x86_64/unistd.h in the Python file.
