Hi!
I'm getting the following error when compiling fobs4jmf from svn on my 64 bit machine :(
ar: creating lib/libfobs.a
g++ -g -dynamic -shared -o lib/fobs4jmf/libfobs4jmf.so src/jmf-pi/decoder.os src/jmf-pi/stand_alone_codec.os -L/home/jack/fobs-build/ffmpeg/lib -L/home/jack/fobs-build/ffmpeg/libavcodec -L/home/jack/fobs-build/ffmpeg/libavformat -L/home/jack/fobs-build/ffmpeg/libavutil -Llib -Lresources/lib -lfobs -lavformat -lavcodec -lavutil -lfaas -lfaad -lmp3lame -lx264 -ldl

If you can somehow get -fPIC on the compliation command line it should fix it
Thx. Ok, if I add the following to src/cppapi/SConstruct and src/jmf-pi/SConstruct
env.Append(CCFLAGS=['-fPIC'])
it should do it? Seems not I get the same error:

:(
the change did not appear to affect the command-line...
Yes, well I don't know where to add the statement: here's my src/cppapi/SConstruct:
ffmpeg_path=fobs.FFMPEG_HOME
env = Environment()
ffmpeg_lib_deps = ['avformat', 'avcodec','avutil'] + fobs.EXTERNAL_LIBS
if env['PLATFORM'] == 'posix':
ffmpeg_lib_deps += ['dl','pthread'] #,z
elif env['PLATFORM'] == 'win32':
env = Environment(tools=['mingw'])
else:
ffmpeg_lib_deps += ['z']
env.Append(CPPPATH=[ffmpeg_path,ffmpeg_path+'/include/ffmpeg', ffmpeg_path+'/libavcodec', ffmpeg_path+'/libavformat', ffmpeg_path+'/libswscale', ffmpeg_path+'/libavutil']+fobs.EXTERNAL_INC_PATHS)
env.Append(LIBPATH=[ffmpeg_path+'/lib',ffmpeg_path+'/libavcodec', ffmpeg_path+'/libavformat', ffmpeg_path+'/libavutil', '#lib']+fobs.EXTERNAL_LIB_PATHS)
if fobs.DEBUG_SYMBOLS == 'yes':
env.Append(LINKFLAGS=['-g'])
env.Append(CCFLAGS=['-g'])
if fobs.OPTIMIZATIONS == 'yes':
env.Append(LINKFLAGS=['-O3'])
env.Append(CCFLAGS=['-O3'])
if sys.platform == 'darwin':
env['SHLINKFLAGS'] = '$LINKFLAGS -dynamiclib -read_only_relocs warning -single_module'
env.Append(CCFLAGS=['-D', '__STDC_CONSTANT_MACROS'])
env.Append(CCFLAGS=['-fPIC'])
env.Library('#lib/fobs',Split('PacketBuffer.cpp Decoder.cpp Encoder.cpp Transcoder.cpp Error.cpp'))
#env.SharedLibrary('#lib/fobsdyn', Split('PacketBuffer.o Decoder.o Encoder.o Transcoder.o Error.o'), LIBS=['fobs']+ffmpeg_lib_deps)
env.Install('#lib', Split('Decoder.h Encoder.h Transcoder.h Error.h common.h'))
env.Program('#lib/samples/test','test.cpp', LIBS=['fobs']+ffmpeg_lib_deps)
env.Program('#lib/samples/tc','tc.cpp', LIBS=['fobs']+ffmpeg_lib_deps)
env.Program('#lib/samples/reencoder','reencoder.cpp', LIBS=['fobs']+ffmpeg_lib_deps)
Sorry, I've definitely run into the fpic problem in other projects, and adding it has worked, but I'm not familiar with fobs's build process.
Ok. I've taken a step forward. env.Append(CCFLAGS=['-fPIC']) did the trick but I had to recompile the libraries (in my case faad, faac, x264, lame). But now I get another error :(

Hi,
for the previous error, you just needed to append the line in both SConstruct files both in
src/cppapi
src/jmfpi
you were just adding it in the src/cppapi and the error was happening in the other directory.
For this other error, you seem to be needing the libz library. Try to append it too to the command line, either manually (editing the appropriate SConstruct files) or by using the parameters of the buildFobs.sh script (see Documentation in the Fobs page to know more about these).

THX :) it works now!

Hm, I was too quick. It build fine now, but when using:
