[Samba] Compiling within Samba Source-Tree

[Peter Koch]

Hi Ralph,

Thanks - you were absolutely right.

I added crypto to the list of the dependencies. Also I
removed all dependencies that I copied from the
smbpasswd-dependency-list besides smbconf and pdb.

Now the wscrip_build entry for my daemon is:

bld.SAMBA3_BINARY('smbscardd',
                  source='smbscardd.c',
                  deps='''
                  smbconf
                  pdb
                  crypto
                  ''')

I tried to do all the initialization that smbpasswd is doing
but I overlooked the first line in the main() routine of
smbpasswd.c:

/*********************************************************
  Start here.
**********************************************************/
int main(int argc, char **argv)
{
         TALLOC_CTX *frame = talloc_stackframe();
         int local_flags = 0;
         int ret;

So I added this line to my main() routine and the final result
is:

root at ns1:/var/tmp/samba-4.19.0# make
PYTHONHASHSEED=1 WAF_MAKE=1  ./buildtools/bin/waf build
Waf: Entering directory `/var/tmp/samba-4.19.0/bin/default'
         Selected embedded Heimdal build

Waf: Leaving directory `/var/tmp/samba-4.19.0/bin/default'
'build' finished successfully (15.537s)


Thanks again - I love this mailing list

Peter
