Hi Zeeshan,

We currently support BigBlueButton on Ubuntu 9.04 32-bit. We've seen
similar problems when running on 64-bit. On a hunch, if you are using
64-bit, check the comments in this issue

http://code.google.com/p/bigbluebutton/issues/detail?id=376

If that does not help, could you provide us the following information

1) How did you install BigBlueButton?

2) The output of

bbb-conf --check

3) The output of

uname -a

Regards,... Fred

Hi Zeeshan,

Given you are running on 64-bit linux, you are hitting some of the
subtle problems. While we have been testing and supporting
BigBlueButton on Ubuntu 9.04 32-bit, others have been trying to get it
to work on 64-bit.

Have you tried looking at the comments in

http://code.google.com/p/bigbluebutton/wiki/DevelopingBBB

Again, we (the core BigBlueButton development team) don't support
BigBlueButton on 64-bit. It's not that we don't want to, but it's a
matter of resources. At the moment, we decided to make sure a few
configurations work well, as opposed to try to support many
combinations (Ubuntu 9.04, 9.10, 32-bit, 64-bit, etc.) and none of
them work well.

Are you trying to setup BigBlueButton as an individual or in a
corporation? If corporate, e-mail me directly; we might be able to
help.

Otherwise, at the moment, most of us are focused on getting
BigBlueButton 0.64 tested and released. I recommend searching
through the past messages in this mailing list as others have gone
down the road of setting up BigBlueButton on 64-bit.

Regards,... Fred

I found this problem too but is a swftools issue rather than BBB and
looks specific for 64 platforms. Some details about swftools bug here:

http://bugs.archlinux.org/task/18201

Anyway, pdf2swf launch a segmentation fault in 64 platforms, so the
line:

String COMMAND = SWFTOOLS_DIR + "/pdf2swf -I " +
presentationFile.getAbsolutePath();

in bigbluebutton-web/src/java/org/bigbluebutton/presentation/imp/
Pdf2SwfPageCounter.java file can't get number of pages. This happend
to me in an old Ubuntu Hardy Heron with swftools 0.8.1, trying to
compile swftools 0.9.0 did not fix the problem because libjpeg-dev
libraries are too old in Hardy Heron and segmentation persist. So I
get last ones:

wget http://www.ijg.org/files/jpegsrc.v8a.tar.gz

Overwrite these files in /usr/include
jconfig.h
jerror.h
jmorecfg.h
jpegint.h
jpeglib.h

recompile swftools 0.9.0 and now all works fine in BBB when upload a
file.

Hi,

So you are hitting the same problem even with 32-bit?

What happens if you run the command in the error log on the command line?
/bin/pdf2swf -I /var/bigbluebutton/0eba91cd-c42c-4ba5-
a4a4-26c4cb21a661/0eba91cd-c42c-4ba5-a4a4-26c4cb21a661/eg09/eg09.pdf
