Title: [SOLVED] Fail to run portaudio examples
Post by: nickob on October 21, 2013, 01:10:30 PM

Hi,

For a project I am working on, I have downloaded and compiled the portaudio library. To check if everything is fine I compiled some examples coming with the lib. Compilation worked, but execution fails with the following message:

Code: (bash) [Select]

./paex_sine: line 1: syntax error: unexpected word (expecting ")")
I do not see what it means.. I am on a RPi model B, with core v4.7.5 running, and alsa, gcc, ... installed.

Thanks in advance,

Nicolas

Which example you run?

You could load the bash extension (if not already done) and try again

Please post output of

Code: [Select]

file -k paex_sine

EDIT:
...in case you have the 'file' extension installed, that is...

I was trying the paex_sine example, located in portaudio/examples.

I compiled the source with:

Code: (bash) [Select]

gcc -o paex_sine -c paex_sine.c -I/usr/local/include/ -L/usr/local/lib -lm -lportaudio
I have the bash extension installed.

$file -k ./paex_sine gives:

Code: (bash) [Select]

./paex_sine: ELF 32-bit LSB  relocatable, ARM, EABI5 version 1 (SYSV), not stripped

Hi,

Good news, I have rebooted and the equivocal message has gone... Yet, the executable still do not launch. Now I get:

Code: (bash) [Select]

./paex_sine: error while loading shared libraries: libportaudio.so.2: cannot open shared object file: No such file or directory
libportaudio.so.2 is actually in /usr/local/lib/ (but not as a symbolic link as it is the case for all the other files), and I had declared the directory to the gcc command.

Did I miss something in the installation of portaudio?

Probably

Code: [Select]

ldconfig

Ok, so I rolled up my sleeves, and built the portaudio extension for the PiCore. If anyone is interested I could share it.

Hi,

Here is the extension (I could not upload it here, because of the file size restriction):

Download link deleted to keep post compliant to Forum rules. bmarkus

Just untar and copy the 3 files to your tce/optional directory, then load it the usual way. You will have to install the alsa extension first to get it work.

The extension was built with piCore version 4.7. I have no idea if this will work on other versions.

Regards,

Nicolas

Nicolas,

contribution to repo always welcome. However Forum rules do not allow posting direct download links. If you have an extension for the repo, send it in email to picoresubmit@gmail.com

Yor extension in the present form doesn't comply to repo repo requirements.

- dev files are not separated
- no .dep file, while extension depends on libasound
- .info file is missing
- breaking upstream license as license text is missing
- it is not compiled against jack, celt, libopus and dbus
- cxx binding is disabled

Please study how extensions packed in the repo and the source tarball.

Bela

P.S. Download link deleted

Sorry, I initially created the extension for my own needs, and I did not intend to produce a formal extension for the repo. I just shared the link to help, but I understand it is not a good practice for the consistency of the whole project.

I will try to wrap it properly and to submit to the repo in a near future.

Regards,

Nicolas

Nicolas,

it is in the piCore 5.x repo already. I suggest to change to 5.x as its repo is reacher, more up to date.
