arts_fft_float is related to aRts, not libart.

Well, fine, I didn't read correctly. Do you know how to resolve the bug? Darrell

Anybody? I never saw this build failure with 3.5.13. Function void arts_fft_float exists in /opt/trinity/include/arts/fft.h. The call to that function exists in tdemultimedia/arts/modules/effects/synth_stereo_fir_equalizer_impl.cc. Darrell

Anybody? Same result with GIT 2803. Darrell

CMake or Autotools?

Autotools. Here is the full build log: http://humanreadable.nfshost.com/trinity/build_logs/tdemultimedia-R14.0.0-i… The error is at the end. I build the package with NUMJOBS=-j1 and --enable-closure. No problems with 3.5.13. Something changed in GIT because other than tdebindings, all other packages build. Darrell

I don't know what would have changed in tdemultimedia...here is the changelog for the effects directory: http://git.trinitydesktop.org/cgit/tdemultimedia/log/arts/modules/effects Are you building any packages with gcc hidden visibility enabled? That might explain the difference. I will see what I can do to replicate the build failure on this end, but it would probably be a good idea to file a bug report. Tim

Yes: qt3, arts, tdelibs, tdebase. I'll rebuild them and try again. Or at least arts because that one is directly involved. How do I disable that option in qt3? I believe qt3 is hard-coded now. Reverse patch? Darrell

Well, I'll be the proverbial monkey's uncle. In arts I toggled -DWITH_GCC_VISIBILITY to OFF, rebuilt and then tdemultimedia finally built. How did you figure that out? Do we need a note in the wiki? You said some time ago that this option was experimental.... Darrell

Experience. :-) It was one of the only ways that a linker failure could result when the correct libraries were already being included via the linker flags.

Things are supposed to Just Work (TM) when that option is enabled. Sometimes a function is not publicly exported when it should be, and that is a bug in TDE. I'll poke around a bit and send in a patch for you to test with WITH_GCC_VISIBILITY set ON. Tim

Please try the attached patch. Apply it to arts, recompile arts with WITH_GCC_VISIBILITY=ON, and then recompile tdemultimedia. Let me know if it works... Thanks! Tim

Works for me, so I committed it to GIT in hash 7395916. Tim

This took a while. Last night after I rebuilt arts with GCC_VISIBILITY=OFF and then successfully built tdemultimedia, I rebuilt all of my packages with that option off. That included qt3, which I had to reverse patch, and the other two core packages. I awakened this morning all packages built (except tdebindings, which is turning into a nightmare). I saw your message that you committed your arts patch to GIT. I updated GIT, restored GCC_VISIBILITY=ON in the core packages and rebuilt qt3 likewise. tdemultimedia built without error. So now we have confirmation that tdemultimedia builds without error regardless of the GCC_VISIBILITY option in the core packages. Both runs are a good test. You said GCC_VISIBILITY is "beta," but we now ran into a bug that the new option exposed and you fixed that. Good job! Darrell
