[Freeswitch-dev] FreeSWITCH-dev Digest, Vol 64, Issue 19

I build FS on Windows every day, I rarely have problems with it, and if a problem occurs it's mostly because of a change in the code that works on Linux, but not Windows - but these kind of problems are usually fixed later the same day (or i just submit a patch, and it will be applied soon enough).

Last time I did a complete rebuild of FS (with no libs downloaded) I also found some problems with openssl (but this has only happened once), but I just removed the openssl-folder and rebuilt, and everything worked, the rest of the things you mention here I've never heard of before. My guess is you have problems related to antivirus or UAC on your machine, but I will try to do a complete new rebuild today, and see how it looks for me - I'll get back to you after that.

Also, please don't hijack other threads, send a new mail the next time, instead of replying to a digest mail.

/Peter

COMPILING FREESWITCH ON WINDOWS 7 FROM THE GIT
-----------------------------------------------------------------------------------------

Hi guys, just to give you some update from the trenches and give you some update on
compiling FreeSwitch on Windows from the git.(what a journey!!!)

I can tell you that so far, it appeared to be one of the most frustrating experience in
building a system from a git: files are missing or are not loaded properly as they should...

So after a few nights of sctatching my head, here is the status:


Building on Windows from a git repository
-------------------------------------------------------------

After git cloning the repository, open vs2008 solution then:

Stop Comodo or any firewall and virus detection
(if not this screws up download scripts giving: util.vbs(184, 2) msxml3.dll errors)

0) launch build

1) insure all the supposed dowloaded directories are present. (!!!!!!!!!!!!! VITAL !!!!!!!!)
Actually there are some problems:

-> issue with opensssl download
-------------------------------------------------
for a strange reason after autodownload  the untar is not complete, resulting in missing subdirectory
So make sure to do it by hand if necessary

-> issue with CELT download
-------------------------------------------
MUST change prebuilt instructions to :
if not exist "$(ProjectDir)..\celt-0.10.0" cscript /nologo "$(ProjectDir)util.vbs" GetUnzip http://files.freeswitch.org/downloads/libs/celt-0.10.0.tar.gz "$(ProjectDir).."
xcopy "$(ProjectDir)\celt\config.h" "$(ProjectDir)..\celt-0.10.0\libcelt\" /C /D /Y /S /I
xcopy "$(ProjectDir)\celt\float_cast.h" "$(ProjectDir)..\celt-0.10.0\libcelt\" /C /D /Y /S /I


2) if you uses Windows sdk 7.1

edit fake-rfc2533.h and comment out :

#ifdef nodef // *****add this
#ifndef HAVE_STRUCT_ADDRINFO

struct addrinfo {
int    ai_flags;    /* AI_PASSIVE, AI_CANONNAME */
int    ai_family;    /* PF_xxx */
int    ai_socktype;    /* SOCK_xxx */
int    ai_protocol;    /* 0 or IPPROTO_xxx for IPv4 and IPv6 */
size_t    ai_addrlen;    /* length of ai_addr */
char    *ai_canonname;    /* canonical name for hostname */
struct sockaddr *ai_addr;    /* binary address */
struct addrinfo *ai_next;    /* next structure in linked list */
};
#endif /* !HAVE_STRUCT_ADDRINFO */

#endif      // *****add this


3) if issue with folder: sofia-sip
cannot include file sip-extra.h ???????????????????????????????????????

(I'm fed up with this so I just decided to get it from a tar)

4) pb on compile : libsndfile

in sofia_presence.c
    if (mod_sofia_globals.debug_presence > 1) {
        int i;                    // to be added
        for (i = 0; i < argc; i++) {

//----------------------------------------------------------------------------------

That's it for the time being, most of the stuff (but not ALL) now compile
and I'll try to focus on other pending issues.

OBVIOUSLY ANY ADVICE IS MORE THEN WELCOME !!!!

Subject: [Freeswitch-dev] == ISSUE building FreeSwitch on Windows
Hi guys,
For the few days I've been unsuccesfull in building FreeSwith on Windows 7

I did follow the Wiki line per line, but some thing is really going wrong:
> apparently the files in /libs directory are not loaded from the net (ie the util.vbs does seem to load and unpack the libs)
error is : freeswitch\libs\win32\util.vbs(184, 2) msxml3.dll: Le système ne trouve pas la ressource spécifiée (ie system doesn't find specified resource)

To summarize:
I loaded the FreeSwitch git repository with TortoiseGit

My config is :
Windows 7/64bits
VSC2008 sp1
Windows SDK 7.1

My firewall is desactivated as suggested

I did follow the recommendation to clear some files:
del libs\apr\include\apr.h
del libs\js\config.h
del libs\js\src\jsautocfg.h
del libs\js\nsprpub\pr\include\prcpucfg.h
del libs\iksemel\include\config.h
del libs\xmlrpc-c\xmlrpc_config.h
del libs\libsndfile\src\sfconfig.h
del libs\sofia-sip\libsofia-sip-ua\su\sofia-sip\su_configure.h
del libs\js\nsprpub\pr\include\prcpucfg.h

cd libs\win32\libsndfile
rename config.h sfconfig.h

Could a guru provide some hints on how to solve this???
Thanks

Subject: Re: [Freeswitch-dev] Strange behaviour in SOFIA SIP
Now I understand.
If both legs use the same codec, the codec ("fake") will be used in a pass-through way,
so no additional transcoding is applied, as in PROXY PASS-THROUGH condition.

So let me reason in a default media scenario (no proxy-media).

Now, as I explained in the first mail, sofia build "ep_codec_string" (SWITCH_
ORIGINATOR_CODEC_VARIABLE) as the intersection between the codec list received
in SDP offer and the codec loaded in the core.
So if the offered SDP codec list is NOT a subset of the loaded core codecs the other
legs will miss some codecs proposed by the calling endpoint.
That said, if I want to be sure every codecs my endpoint support won't be filtered I
have to register a "fake" pass-through codec for each one.

... you did not answer to my last question :).
I haven't found any other endpoint module the can interwork in PROXY mode with
sofia (even h323 doesn't support this). My question: is there a standard/
recommended way to exchange capability between endpoint of different nature in FS
proxy mode? Maybe using SDP o/a as done in sofia sip?

Thank you again for you help.
Giovanni

that's what I was trying to explain.
PROXY mode does not let you manipulate anything, it's pure
pass-through negotiation between the endpoints.

All the stuff with ep_codec_string are relevant only when you are not
trying to use proxy mode.
This is a common mistake people make assuming not using proxy mode
means somehow doing more work but it's not the case, any time both
legs of a call use the same codec it's equally efficient to what you
end up with in proxy mode.  proxy mode simply means take the inbound
SDP and offer it AS IS to the far end and vice-versa and use a fake
codec in the middle that is agnostic.

I believe that you might be missing some system dll's on your machine.

msxml3.dll is something that should exist on your computer, and I think the download script is depending on it.
