TCL(Tool Command Language) Scripting :: Building Tcl on Linux/Itanium


	Building Tcl on Linux/Itanium I did an --enable-64bit and checking the flyby I see this: checking if 64bit support is requested... yes checking if 64bit Sparc VIS support is requested... no checking system version...

Also, in what cases would you want to pass "--enable-shared"?

If gcc on that machine doesn't accept -m64, then you need an update. We use gcc 3.2.3, and it has been a standard opt for years. > Also, in what cases would you want to pass "--enable-shared"? That's the default.

Well, as Itanium is 64bit only, there is no such compiler switch. Tcl's configure script does not know how to handle this architecture. On the other hand, I compile Tcl/Tk 8.4.14 for Linux/Itanium on a SLES 10 machine with gcc 4.1.0 for some weeks now and it seems to run okay. My application's test-suite runs without failures, Tcl's shows two failures which are due to my environment. There are a couple of Tk tests failing, on which I haven't look closer at, however. kind regards -- Matthias Kraft Software AG, Germany Matthias Kraft wrote: > There are a couple of > Tk tests failing, on which I haven't look closer at, however. It's fairly usual for some Tk tests to fail. They tend to be very sensitive to your environment (and it's often hard to change this in any meaningful way).

That's funny - you are correct, although the docs do clearly state support for -m64/-m32, it is not supported. However, it is not correct that Itanium is "64-bit only". It is a true 64-bit chip, but you can create 32-bit executables natively for it (at least on HP-UX IA64 you can). > On the other hand, I compile Tcl/Tk 8.4.14 for Linux/Itanium on a > SLES 10 machine with gcc 4.1.0 for some weeks now and it seems to run > okay.

Yes, ActiveTcl is available for Linux-ia64 as part of our enterprise distribution set. We have had to tweak a few extensions to properly support things, but the core should be in good shape.

Well, when looking into the IA64 sub model options, there is no -m64/-m32 documented (gcc 4.1.0). As far as I know the "32bit" mode is special to HP-UX in that certain types are reset to the usual length they have in a 32bit environment. kind regards -- Matthias Kraft Software AG, Germany Jeff Hobbs schrieb: >> Well, as Itanium is 64bit only, there is no such compiler switch. >> Tcl's configure script does not know how to handle this architecture. > That's funny - you are correct, although the docs do clearly state > support for -m64/-m32, it is not supported.
