Hello devs, just built from git. I tried the three Lua csd from the examples/opcode_demos directory: luamoog.csd and lua_scoregen.csd run fine; but luaopcode.csd gives a segfault. |

Are you on x86_64? I think the luajit has issues on 64bit. It does segfault here on OSX (and if I remember well, in Ubuntu).

I'm on x86_64. But it used to work recently. So I don't think that the problem comes from Luajit. It seems it has something to do with recent string changes... 2013/6/10 Victor Lazzarini <Victor.Lazzarini@nuim.ie> Are you on x86_64? I think the luajit has issues on 64bit.

| Well, I can't test it, but by looking at it, the opcodes seem to be using the new string code. On 10 Jun 2013, at 20:02, Francois PINOT wrote:

I think you're right, because the lua code in the CSD does not seem to handle the new string variables, maybe it needs to be updated. I think the actual C++ code for the opcodes is probably OK. On 10 Jun 2013, at 20:10, Victor Lazzarini wrote:

I had to change the Lua opcodes in Csound 6 to get them to work on Android. I replaced OpenMP critical sections with pthreads mutexes, and I changed the string handling to use STRINGDATs. Are you using the latest sources? Hope this helps, |

I was wondering whether the lua code needed to be changed to deal with STRINGDAT. I see this in the CSD, for example print(string.format('stringin: %s', ffi.string(arguments.stringin))) arguments.stringin would, in the old string code be a string, but now it's a STRINGDAT. I don't know whether this has already been modified, or whether it needs to be modified at all. On 11 Jun 2013, at 02:36, Michael Gogins wrote:

Here on Ubuntu 12.04, 32 bit, csound_ffi.csd example is working. With Csound6 build yesterday. Ciao, francesco. PS: I have problem with audio ( unknown rtaudio module: 'jack', using dummy module rtaudio: dummy module enabled) same using alsa. But only with this example. -- View this message in context: http://csound.1045644.n5.nabble.com/Segfault-with-lua-tp5724352p5724368.html Sent from the Csound - Dev mailing list archive at Nabble.com. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Csound-devel mailing list Csound-devel@lists.sourceforge.net |

I can confirm that the luaopcode.csd does not work after I changed the LuaCsound.cpp code to use STRINGDATs. Victor, are you saying that the "char *stringin" in the Lua code needs to be "STRINGDAT *stringin"?
That would require the STRINGDAT struct to be defined in the Lua cdef also. I will make these changes if that is the case.

| yes, that is what I meant. In that case stringin->data is the string stringin->size is the size of the data mem. Victor On 11 Jun 2013, at 10:16, Michael Gogins wrote:

I wasn't home for the last two days. Just tried it. I had to change csound64.dll to csound64 (line 7) to get it working on my system (Ubuntu 12.04 x86-64). Many thanks Victor and Michael2013/6/11 Michael Gogins <michael.gogins@gmail.com>
