Help for preparing an FLTK plug-in opcode

[Uğur Güney]

# Hi,
# I'm trying to make an oscilloscope using FLTK, because the display
opcode works only on X11.
# I successfully made a very simple (sinusoidal waveform calculating)
plug-in opcode looking at the documentation: ugur2.c For this one, I
have only one question. When I compiled it and made it a .so file and
called its opcode from Csound etc.  it said that "incompatible opcode"
I understand that this is because of MYFLT is default a float and my
Csound version is double. I added a line in the ugur2.c file "#define
MYFLT double" to handle the situation, it works but I get always a
warning which says MYFLT was defined twice. (It is defined in
csound.h) How can I say to compiler that MYFLT is double without
defining it twice.

# I do not know the cause of my second question. I added some FLTK
code for creating an FLTK window, which is the first example in
the FLTK documentation. (same file with additional code from FTLK
example: ugur4.cpp) But I do not know whether I made it correct.
# The file compiled without errors. I copied the .so file under
plugins64 folder but Csound gave this warning:

WARNING: could not open library '/usr/lib/csound/plugins64/ugur4.so'
(/usr/lib/csound/plugins64/ugur4.so: undefined symbol: _Znwj)

# What may be the reason of this warning?
# My system is Ubuntustudio 8.04 and csound 5.08 double version.
# Thanks in advance!

1) MYFLT: don't define it yourself, use -DUSE_DOUBLE

2)It's a link error, try building the C++ code with g++ instead of
gcc (If you have not done so). One of the default C++ libs seems
to be missing.

Note that you need -fPIC to build shared libraries.
I did this and succeeded:

Here are my notes on installing csound5 from source on Fedora 8. I got a
 segfault with the Linux binary installer hence the attempt to install
from source.


----------------------------------------------------------------
Building csound 5.08 from source
--------------------------------
1. download Csound5.08.tgz  from sourceforge

2. tar xzf Csound5.08.tgz

3. cd Csound5.08

4. run scons -h and work out what devel packages to install. I installed

libsndfile-devel
portaudio-devel
fltk-devel
fluidsynth-devel
jack-audio-connection-kit-devel
liblo-devel
tcl-devel
tk-devel

5. edit custom.py and modify the path to fltk as follows

if sys.platform[:5] == 'linux':
    platform = 'linux'
    customCPPPATH.append('/usr/include/FL')
    customLIBPATH.append('/usr/lib')

6. try and run scons as follows

scons useDouble=1 buildCsound5GUI=1 generatePDF=1 \
      buildStkOpcodes=1 buildTclcsound=1 buildVirtual=1 \
      useOSC=1 buildLoris=0

(note I couldn't use gcc4opt=1 as I got an error in config.log with
an unrecognised option mtune=1)

This failed as /usr/include/FL (the fltk include files) included
a file math.h, which was used in preference to the system math.h

I tried renaming /usr/include/FL/math.h to /usr/include/FL/fl_math.h

The next failure was with dirent.h - I tried renaming

/usr/include/FL/dirent.h to /usr/include/FL/fl_dirent.h

A better solution with gcc would be to use -idirafter /usr/include/FL
which would cause that directory to be searched *after* the system
include paths, thus ensuring the correct version of math.h and dirent.h.
However I don't know how to do that with scons.

The next failure was the missing "fluid" command. To fix this:

yum install fltk-fluid

Finally building completed.

7. To install

./install.py

8. Edit your .cshrc or .bash_profile and set
export OPCODEDIR64=/usr/local/lib/csound/plugins64

or

setenv OPCODEDIR64 /usr/local/lib/csound/plugins64

9. set

RAWWAVE_PATH /usr/local/share/csound/rawwaves

in either .bash_profile or .cshrc

# Thank you very much Felipe and everyone! I both did not use the
`fltk-config --ldflags` in creating the .so file and did not used the
-fPIC flag (I do not know what is it used for but will invesitage
about its meaning)
# Now I succeed to create an FLTK window from Csound without any errors.
# Have a nice day!

gcc4opt take i386 or k8 or k6 or pentium or similar values.

PS Setting that option is Well Worth It!  I have been doing some
tracing/instruction counting etc and it takes trapped from 24
billion(US) instructions to 13 if I set gcc4opt=i386
  Still working on it though

Hi Alan,

Thank you for posting this guide. I've been building checkouts of
Csound from CVS since long time using Fedora and always thought about
starting some wiki or blog page where to post a guide for Linux users
wanting to build Csound (I often see people in the list asking for
instructions). The only step I found surprising in your guide was the
one about changing the path to FLTK in custom.py. In all my builds
(including the last one one month ago) using Fedora 8 I've never had
to touch that file or had the problems with the math.h and dirent.h
files. And I've been building with almost everything except for
CsoundVST (and FLTK works). Did you try building without changing
custom.py?

I'm glad John answered the question regarding the value for gcc4opt,
I've been trying to use that flag and getting the same error you got
and since then forgot to try again. It might help with the
performance. Is i686 the right value for a core2duo processor?

Cheers,

Hector

Consult the gcc manual.

The correct value for Core 2 Duo is nocona.

Hi Mike,

Thanks for the information. I checked the gcc manual and there is also
a core2 option:

           nocona
               Improved version of Intel Pentium4 CPU with 64-bit extensions,
               MMX, SSE, SSE2 and SSE3 instruction set support.

           core2
               Intel Core2 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3
               and SSSE3 instruction set support.

This is gcc version 4.1

Cheers,

Hector

I do not have a core2duo so am not sure wht it is

i686 is safe and resonable.  You nmight consider
           prescott
               Improved version of Intel Pentium4 CPU with MMX, SSE, SSE2 and
               SSE3 instruction set support.

           nocona
               Improved version of Intel Pentium4 CPU with 64-bit extensions,
               MMX, SSE, SSE2 and SSE3 instruction set support.

That's why I posted it, I was hoping someone would tell me where I
should put it. I'll have to have a look at csounds.com

Yes, that didn't build.

Here is the problem I was trying to solve

Hi Hector,
  how did you install FLTK? I installed it using yum - I'm not sure if
that means I've got enable-threads or not.

Perhaps if you installed from source the headers end up in a different
place?

Alan

aah! I see.. I didn't realize you are building for 64-bits kernel,
that's why you might have the FLTK problems and I don't (I'm using a
32-bit kernel with a core2duo). Today I just rebuilt from CVS using
gcc4opt=core2 and it seems to be working fine and I think I'm noticing
a slight performance improvement, but still have to do more testing.

Cheers,

Hector
