Modules don't build on Linux
Last modified: 2018-08-20 11:51:26 UTC
Modules fail to build on Linux. The problem is partly fixed for Nyquist Workbench (see URL link), though Nyquist Workbench still does not work. The build failure for mod-script-pipe appears to be similar to the original issue in mod-nyq-bench. Both mod-script-pipe and mod-nyq-bench work in r12860 but not in r12861.
(In reply to comment #0) Error in original post. The revision numbers are incorrect, I think it should have been r12960. Checking that now.
(In reply to comment #1) Both mod-script-pipe and mod-nyq-bench build on r12959. I've only tested Nyquist Workbench and that works as expected.
Update to test builds: r12959 Audacity: build successful. mod script pipe: build successful Nyuist workbench: build successful and works as expected. r12960 Audacity: build fails. Modules not tested. r12960 Audacity: build successful. mod script pipe: build fails Nyuist workbench: build fails r13011 Audacity: build successful. mod script pipe: build fails Nyuist workbench: build successful but module fails to load (As discussed in the URL, the error reported in the log is: Error: /home/steve/.audacity-files/modules/mod-nyq-bench.so: undefined symbol: gAudioIO) r13090 Audacity: build successful. mod script pipe: build fails Nyuist workbench: build successful but module fails to load (same error message as for r13011).
(In reply to comment #3) Rats, why can't these posts be previewed :( The second listing for r12960 should have been r12961 r12961 Audacity: build successful. mod script pipe: build fails Nyuist workbench: build fails
Just committed r13093 and r13094. They should correct the loading of mod_nyq_bench and building of mod_script_pipe.
(In reply to comment #5) Nyquist Workbench appears to be working correctly in r13094.
(In reply to comment #6) and mod-script-pipe builds OK.
Not managed to build Nyquist Workbench in Ubuntu 13.10. In file included from /home/gale/audacity/src/Project.h:27:0, from NyqBench.cpp:28: /home/gale/audacity/src/AudioIO.h:16:23: fatal error: portaudio.h: No such file or directory #include "portaudio.h" ^ compilation terminated. make: *** [NyqBench.o] Error 1 What I did was: 1 sudo make clean 2 svn up 3 autoreconf --no-recursive 4 ./configure 5 sudo make 6 cd to and changed /lib-src/mod-nyq-bench/Makefile to: AUDACITY_DIR ?= /home/gale/audacity/ 7 make Also tried restoring original /lib-src/mod-nyq-bench/Makefile with no changes i.e. AUDACITY_DIR = ../.. with same result. Let me know if I am missing a step somewhere.
(In reply to comment #8) Try using a fresh svn checkout.
It was because Gale doesn't have portaudio-devel installed. Just committed a change to allow it to build in that case.
(In reply to comment #10) That seems a bit odd because when I built Audacity on Ubuntu (14.04) this evening, portaudio19-dev was pulled in when I ran: apt-get build-dep audacity
There somehow had to be a portaudio/include directory in the search order for includes for it to be working without portaudio-dev installed. The module build simply had no other way of finding them. I just made them look at the lib-src portaudio version. It's really just to satisfy the Audacity header dependencies and so the lib-src version will work just fine even if the system portaudio is being used for Audacity.
(In reply to comment #12) Hi Leland When I checked "sudo apt-get build-dep audacity" I indeed did not have portaudio19-dev or a few other packages installed, but I have not changed this since I installed Ubuntu 13.10. Without running "sudo apt-get build-dep audacity", I updated to r13097, rebuilt Audacity and was able to build mod-nyq-bench. However Devices Preferences still said "Using: PortAudio V19-devel" and always has IIRC. I was still able to build mod-nyq-bench after running "sudo apt-get build-dep audacity" and rebuilding Audacity. So this seems OK. I also built mod-script-pipe. Then I installed Audacity (the executable is at /usr/local/bin) and ran it, and did cd to the /home/gale/audacity/scripts/ directory and ran ./pipe-test.pl. It runs but it spews out "cannot export to /home/gale/pipetest/" errors for all the export steps. Can I assume I am not doing this right, or was it always like this on Linux, or is something in https://code.google.com/p/audacity/source/detail?r=13094 causing this?
(In reply to comment #13) > It runs but it spews out "cannot export to > /home/gale/pipetest/" errors for all the export steps. Can I assume I am not > doing this right, or was it always like this on Linux I think that is "normal" (if not, it's been doing that for a long time). If you manually create ~/pipetest it should run OK.

OK, that works. RESOLVED - FIXED. Thanks, Leland & Steve.
