translate library names by only adding ".so" to them without
prepending them with "lib". Add the flag DSO_FLAG_NAME_TRANSLATION_EXT_ONLY
for that purpose.
appropriate filename translation on the host system. Apart from this point,
users should also note that there's a slight change in the API functions
too. The DSO now contains its own to-be-converted filename
("dso->filename"), and at the time the DSO loads the "dso->loaded_filename"
value is set to the translated form. As such, this also provides an impicit
way of determining if the DSO is currently loaded or not. Except, perhaps,
VMS .... :-)
The various DSO_METHODs have been updated for this mechanism except VMS
which is deliberately broken for now, Richard is going to look at how to
fit it in (the source comments in there explain "the issue").
Basically, the new callback scheme allows the filename conversion to
(a) be turned off altogether through the use of the
DSO_FLAG_NO_NAME_TRANSLATION flag,
(b) be handled in the default way using the default DSO_METHOD's converter
(c) overriden per-DSO by setting the override callback
(d) a mix of (b) and (c) - eg. implement an override callback that;
(i) checks if we're win32 "if(strstr(dso->meth->name, "win32"))..."
and if so, convert "blah" into "blah32.dll" (the default is
otherwise to make it "blah.dll").
(ii) default to the normal behaviour - eg. we're not on win32, so
finish with (return dso->meth->dso_name_converter(dso,NULL)).
(e) be retried a number of times by writing a new DSO_METHOD where the
"dso_load()" handler will call the converter repeatedly. Then the
custom converter could use state information in the DSO to suggest
different conversions or paths each time it is invoked.
ld warns that -Fl "may not be supported in future releases". We know
that, and are doing things in HP-UX 11 (64bit), so turn off that
warning with +vnocompatwarnings.
you should defined _THREAD_SAFE (I found that in an include file, and
that's what everybody tells me) or _THREADSAFE (that's what the gcc
manual says in the FreeBSD-specific section), so I defined both, just
to be safe.
NCONF_get_number_e() is defined (_e for "error checking") and is
promoted strongly. The old NCONF_get_number is kept around for
binary backward compatibility.
to have the full extension information, so residual shared libraries
can be removed so the applications and test programs do not get linked
against them by mistake...
- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.
- Make as few rebuilds of the shared libraries as possible.
- Still avoid linking the OpenSSL programs with the shared libraries.
- When installing, install the shared libraries separately from the
static ones.
Actually, it's a feature that it goes looking at environment
variables. It's just a pity that it's at the cost of the error
checking... I'll see if I can come up with a better interface for
this.
