[LAU] Tranches build problems in Ubuntu 8.04

Hello:

I've been asked by Florent Berthaut, the developer of Tranches.
I'm posting to both lists just in case this problem isn't exclusive to
Ubuntu 8.04.

I just tried building Tranches in UbuntuStudio 8.04, and came up with
some errors, the first of which is below:

src/base/tranches.o: In function `__exchange_and_add':
 /usr/include/c++/4.2/ext/atomicity.h:51: undefined reference to
 `__sync_fetch_and_add_4'
 /usr/include/c++/4.2/ext/atomicity.h:51: undefined reference to
 `__sync_fetch_and_add_4'

 `__sync_fetch_and_add_4'
 src/base/tranches.o:/usr/include/c++/4.2/bits/basic_string.h:234: more
 undefined references to `__sync_fetch_and_add_4' follow
 collect2: ld returned 1 exit status
 scons: *** [tranches] Error 1
 scons: building terminated because of errors.

I contacted the developer, Florent Berthaut, and he provided this
modification for the SConstruct script:

env = Environment(CC = 'gcc',CCFLAGS ='-I/usr/include/libxml2/
-I/usr/include/lash-1.0/',LIBS=['asound','lash','pthread','xml2','sndfile','samplerate','jack'])
env.ParseConfig('fltk-config --libs --cxxflags --ldflags --use-images')

The modification yielded this error when trying to build Tranches:

In file included from src/audio/../base/tranches.h:31,
               from src/audio/jackProcess.cpp:26:
src/audio/../base/../lash/lashClient.h:28:23: error: lash/lash.h: No such
file or directory
In file included from src/audio/../base/tranches.h:31,

token

token
scons: *** [src/audio/jackProcess.o] Error 1
scons: building terminated because of errors.

Florent's first question was whether I had lash-dev installed: as it
turns out I did. This modfication came later...

env = Environment(CC = 'gcc',CCFLAGS ='-I/usr/include/libxml2/
',LIBS=['asound','lash','pthread','xml2','sndfile','samplerate','jack'])
env.ParseConfig('fltk-config --libs --cxxflags --ldflags --use-images')
env.ParseConfig('pkg-config --libs --cflags lash-1.0')

Tranches was built sucessfully after using this modification to
SConstruct. Florent asked that I post this to the lists for anyone
that might be having a similar problem.

Now I just have to figure out how Tranches works ..... ;)

Thanks,
Ernie
