compiling snack package with tcl8,6

[Luc Moulinier]

Hello everybody,

I'm trying to compile the snack package v2.2.10 using tcl/tk 8.6.7 (64 bits) for macOS but the compilation failed (see below). As a test, I tried also to compile the unix version but it failed also.

I used the ActiveState teapot source code. The activeState binary version for macosx does not work, the libsnack.dylib can not be loaded.


Does anyone know about a new version or a mac x86_64 compatible version.? Or is there an alternative to snack ?

Many thanks in advance !

I use an interface to VLC.
I have never used snack, so I don't know if it is a proper alternative.

https://wiki.tcl-lang.org/page/VLC+Tcl+Extension

I believe undroidwish includes a VLC interface.

No mac experience here. I used Fedora 22 srpms for my RHEL 6.5 without major problems. They have several patches and dependencies.

From the tcl-snack.spec:
BuildRequires: tcl-devel, tk-devel, libogg-devel, libvorbis-devel
BuildRequires: libXft-devel
BuildRequires: alsa-lib-devel
BuildRequires: python-devel
Requires: tcl(abi) = %{tcl_version}
...
%configure --disable-static --with-tcl=%{_libdir} --with-tk=%{_libdir} --with-ogg-include=%{_includedir} --with-ogg-lib=%{_libdir} --enable-alsa
make %{?_smp_mflags} EXTRACFLAGS="%{optflags}"

Versions:
SOURCES/libogg-1.1.4.tar.gz
SOURCES/snack2.2.10-nomp3.tar.gz
SOURCES/tcl-core8.6.4-src.tar.gz

Maybe this helps...

I had the same problem on Windows and applied the patch appended at the
end to the *TCL* (not snack!) sources, which basically enables
Tcl_SeekOld and Tcl_TellOld in the TCL library again.

After that, the linker should find those symbols for snack.

Dear Ralf,

Thank you for the trick. It works indeed, but I got an other error when linking with Tk. The linker can not find _TkPutImage when compiling with tcl/tk 8,6,7. (I don't know why it want to use TkPutImage with snack but ....)

Maybe you have an other brillant idea ? ;-) ?

Thanks again !!
