Hi all,

I grabbed this:

    http://www.thumbuki.com/TheCsoundBlog/message_from_another_planet.csd

and I'm running it with:

    csound -d -+rtaudio=alsa -o dac:hw:0,0 message_from_another_planet.csd

and I get no sound and a message that says "Csound tidy up: Segmentation fault".

This is csound 1:5.12.1~dfsg-5 from Debian on amd64.

Erik

No such problem here on OSX, with last week's CVS checkout.

I'd be happy to if I could figure out how to build a Debian 
package with debug symbols. Unfortunately, the installed binaries
don't have debug symbols and I can't figure out how to build a
packge with debug info.

I looked at building csound in a chroot, but that simply doesn't
work. Running build-linux-double.sh failed with:

    Checking for C header file stdio.h... no
     *** Failed to compile a simple test program. The compiler is
     *** possibly not set up correctly, or is used with invalid flags.
     *** Check config.log to find out more about the error.

Looking on config.log I see:

    .sconf_temp/conftest_1.c:1: error: CPU you selected does not support
    x86-64 instruction set

probably as a result of -mtune=prescott.

However, I know that my machine does support the x86_64 instruction
set and that I have build x86_64 binaries of libflac, libogg, libvorbis
and libsndfile in this same chroot.

This should work:

 DEB_BUILD_OPTIONS=nostrip dpkg-buildpackage

However, I don't know if the combination of -O3 and -g will prove useful.

That script optimizes for (ie, it asks to build for) an atom
processor, which is not 64bit.

Thanks Felipe. That worked.

Here's the backtrace:

My comments were more general than that specific problem.

For most projects, you can download the sources and do:

     ./configure
     make

Most projects also have an INSTALL file containing instructions.

Csound doesn't use a standard configuration and build tool, and
the instructions in the INSTALL file point to

    http://csounds.com/manual/html/BuildingCsound.html

which provides the most complicated configuration instructions
I've ever seen for an open source project. Couldn't the vast
majority of the configuration options be automatically tested
for instead of making the user provide them?
