Is there any place were I can download libvnc* binaries for Windows?

[silvioprog]

Hello,

I'm trying to compile libvncserver on Windows 7 using MinGW-w64 Win32 Shell, but I got some errors that breaks the compilation.

I tried to compile the following versions:

. LibVNCServer-0.9.10:

Error:

(tried with --with-libgcrypt-prefix too, but got same error);

. Current trunk (commit 9d4cb56 on 3 Dec 2015):

(tried with --with-libgcrypt-prefix too, but got same error).

I can't fix it because my C knowledgment is a little bit beginner, then I can't compile it. So, is there any place were I can download the libvncserver (server and client) binaries (.dll) for Windows (32 and/or 64 bits)?

Thank you!

[silvioprog]

Tried it too (disabling the TightVNC file transfer protocol):

$ ./configure --without-filetransfer

Output:

[bk138]

Did you run configure beforehand?

[silvioprog]

Sorry for my ignorance, but, how to do it? I just try the commands below:

./configure
make
make install-strip

Is there some additional commands/params specific for Windows?

[bk138]

Your configure log says there's no system gettimeofday - can you post the detailed config.log file?

[bk138]

Also, did you read https://libvnc.github.io/#building ?

[silvioprog]

Yes, I did this basic steps, using the parameters for my system, but I can't compile that. I believe that I can't (unfortunatelly) use libvnc on Windows, because I can't compile it and there is no place to download pre-compiled binaries. :-(

[bk138]

The tightvnc file transfer configure option was wrongly named. Pls try current master.

[silvioprog]

I'm going to test it again and back with some feedback. :-)

[silvioprog]

Sorry for late answer, I tried to compile it using the commands above and this new commands below, btw I got another error:

And about this example below (from the libvncserver doc):

CPPFLAGS=-DWINVER=0x0501 ./configure  \
        --build=<your build system type> --host=i686-w64-mingw32 --with-sdl-config=<your win32 sdl-config> \
            --with-zlib=<path to your win32 zlib> --with-jepg=<path to your win32 libjpeg> \
            --with-gnutls=<path to your win32 gnutls or 'no'> \
            --with-gcrypt=<path to your win32 libgcrypt or 'no'> 

I don't know what means "-DWINVER=0x0501" (what is 0x0501?) and "--build=" (--build=win32?).

Usually I just perform "./configure && make && make install-strip" and it compile many libraries, but I'm getting this problems with libvncserver and I don't know how to fix that. :-(

[bk138]

Looks like you don't have gnutls built.

[silvioprog]

I already had installed gnutls to compile another package:

$ cat /mingw32/include/gnutls/gnutls.h | grep GNUTLS_VERSION_NUMBER
#define GNUTLS_VERSION_NUMBER 0x030405

I think that nobody tried to build libvncserver on Windows besides me.

[Pernat1y-zz]

Some time ago I have crosscompiled it for Windows under Fedora. Will try to reproduce on recent version...

[silvioprog]

Thanks a lot @Pernat1y , this library will help me a lot on Windows.

[cgeorges82]

Hello @silvioprog and everybody

I also need libvncserver and I think I solved some problem. Firstly it's best to use the master branch I try this with MSYS2:

cd libvncserver-master
autogen.sh
CPPFLAGS='-DWINVER=0x0501 -I<include path>' LDFLAGS='-L<lib path>' ./configure --build=i686-w64-mingw32 --host=i686-w64-mingw32 --prefix=...

add I tried some additional options --with-sdl-config = no : no need sdl (I'll use Qt). --without-tightvnc-filetransfer : must include pwd.h that describes the groups and users of files. (custom or from other library ?) --without-ssl --without-gnutls : websockets compiles only in no tls-ssl mode --without-websockets : compile only with 2.4.0<gnu-tls<2.99.1 and with openssl I had another obscure error message --disable-silent-rules : make verbose --without-ipv6 : libraries compile but examples don't work. Error in libvncserver/sockets.c:434 - rfbProcessNewConnection: error in select ... (Result to large or Invalid argument) this select function only work with ipv6 -DWINVER=0x0501 : seems not required but I keep it. That determines the minimum platform SDK (0x0501 = WinXP)

During compilation I got this message libtool: warning: undefined symbols not allowed in i686-w64-mingw32 shared libraries; building static only. In fact I only get libvncserver.a and libvncclient.a but all examples work well even if someone logging many warning message.

I try also with CMake, and I got dynamics librairies. But examples don't works cause IPv6 is disabled. I made some modification to have LIBVNCSERVER_IPv6 option with cmake. I'll send a pull request this evening.

I hope that help you

[silvioprog]

Hello @cgeorges82 , thanks for answer.

Do you sent the pull request?

I tried to compile that but I get same errors:

[cgeorges82]

Sorry, lot of work this week. I just send a pull request, but currently you must compile --without-tightvnc-filetransfer --without-ssl --without-gnutls --without-websockets --disable-silent-rules. For example, tightvnc-filetransfer requires pwd.h, but it is not part of MINGW or MSVC. You can find some porting implementation on the web but I don't try any. Same things for websockets who requires resolv.h and sys/uio.h.

@cgeorges82 sry for the late reply. Concerning https://github.com/LibVNC/libvncserver/pull/105, what are the gnutls changes for if you build without gnutls?

[cgeorges82]

Sorry for the late reply. I aggre, that change nothing. But when I try to compile with it, I got "undefined reference to ` gnutls_transport_set_global_errno'". So I try to solve it. Finally websocket don't work on Windows with MinGW, but I still send that pull request.

You can leave the gnutls changes in there, but then I would expect that to build with gnutls. I am referencing your comment from Mar 5.

[silvioprog]

Hello guys, terrible sorry for late answer. Finally I'm programming in C language and I'm studying it a lot, including some tools like Doxygen, autotools, etc. Well, I solved the problem and now my libvncserver copy compiles like a charm on MinGW-w64, then I sent all changes to this pull-request: https://github.com/LibVNC/libvncserver/pull/154. After applying this PR, you just need: ./configure --without-tightvnc-filetransfer && make install-strip, and the magic happens. Anyway, libvncserver should keep its sources more mingw compatible, ie, I have socket/select available in my system, but libvncserver's pre-compilation always returns checking for select... no and checking for socket... no. I'm very busy developing a project to the company I'm working for, but probably I'll check how to compile tightvnc-filetransfer on Windows (mingw) allowing to use the option --with-tightvnc-filetransfer on that too. Thank you! :+1:
