Hi Guys,

Had a brief discussion with Rory Walsh about this on Cabbage forums a while back and I also briefly mentioned this problem in my last email about OSC opcodes.

I’ve been having this weird issue where when I install csound on a linux machine (through package manager or building manually) I’m unable to access the serial opcodes. Each time, my user is part of the dialout group, and even running as root gets no results. I can see that the serial opcodes are building successfully, but when I csound -z they don’t appear and they’re unrecognised when running a csd containing them.

Currently doing a fresh Ubuntu install and I’ll build it after, but I’m not really expecting positive results. It’s maybe worth noting that these are powerpc machines, specifically iMac G3 and PowerMac G4, and I’ve had this issue on Ubuntu, Debian and Void.

Does anyone have any thoughts? I’m pretty new to linux and building software in general.

Cheers!

hi rhys -

i am on debian and followed the description in 
https://github.com/csound/csound/blob/develop/BUILD.md#debian

in my cs6make folder, i have CMakeCache.txt, and in it:
//Build the serial opcode
BUILD_SERIAL_OPCODES:BOOL=ON

so if you can set this option (which is perhaps OFF in your case), or 
run cmake with BUILD_SERIAL_OPCODES=ON, it should build the serial 
opcodes.  i had a look with csound -z, and the serial opcodes are there.

best -
	joachim

Hi Joachim,

Yeah I actually did check that out as I assumed there would be somewhere specifying whether they should be built or not. That option is set to true, and I can see them being built in the console output.

it's somehow strange that they are building but not part of your csound. 
  perhaps you have two versions of csound?  if you first installed from 
the repo, you will have /usr/bin/csound, and your other version will be 
/usr/local/bin/csound.  you can try
	/usr/local/bin/csound -z

if you use pd, you might consider to use the csound6~ object:

In mty setup libserial.so is built in the build directory and has little 
dependency

xenakis:~/csound6> ldd libserial.so
         linux-vdso.so.1 (0x00007fff377ea000)
         libc.so.6 => /lib64/libc.so.6 (0x00007f9b9165e000)
         /lib64/ld-linux-x86-64.so.2 (0x00007f9b91c1c000)


As a pugin it gts loaded if it is found when csound is run

I clearly have not understood yur setup
