Building for 64-bit?

[rmfought]

Any tips for building for 64-bit?  I am used to seeing a configure script before the make.

Do you mean building Sonic Visualiser?  On which platform -- Linux?

The qmake + make should work correctly for 64-bit Linux builds.  There is one line of code in the 1.0 release that may not compile in a 64-bit environment -- line 64 of sv/osc/OSCQueue.cpp:

    case 'h': message.addArg(arg->h); break;

If the build fails there, just comment out that line (with "//" at the start), as it isn't necessary anyway.

I've never actually used SV in a 64-bit distribution, but reports suggest that it does work OK.

I'm running gentoo on amd64.  Gentoo provides an ebuild, which succeeds to build but always tells me, when I open a file:

Code: [Select]

Could not open an audio device for playback.
Audio playback will not be available during this session.

So I tried to build straight from the SVN trunk.  First, I had to change the -march in sv.prf to athlon64 instead of pentium-m.  Here's a diff of the change I made:

After that change, run qmake -recursive to rebuild the makefiles.  But there is still a compilation error, and I'm stuck here.

Any advice?

To help any other gentoo users out there...

I was able to get the gentoo ebuild of sonic visualiser 1.0 to play audio, by following the instructions here: http://gentoo-wiki.com/HOWTO_Jack

I never got past the build error above, trying to compile the latest sonic visualiser.

About the build error: My guess is that you have PortAudio v18 installed, and you need PortAudio v19 for SV (or else edit the sv.prf to tell it that you have v18, although that hasn't been tested recently).
