Hey Joseph,

I think all dependencies are ok now, though I'm a bit confused about what
the 'linux-gate.so.1' dependency is, since by the looks of it, it doesn't
point anywhere.

ldd /usr/local/bin/pdf2swf
         linux-gate.so.1 =>   (0x00beb000)
         libmp3lame.so.0 =>  /usr/lib/libmp3lame.so.0 (0x00cbf000)
         libungif.so.4 =>  /usr/lib/libungif.so.4 (0x00dbf000)
         libjpeg.so.62 =>  /usr/local/lib/libjpeg.so.62 (0x00c01000)
         libz.so.1 =>  /usr/local/lib/libz.so.1 (0x00755000)
         libfreetype.so.6 =>  /usr/local/lib/libfreetype.so.6 (0x006cd000)
         libstdc++.so.6 =>  /usr/lib/libstdc++.so.6 (0x00991000)
         libm.so.6 =>  /lib/libm.so.6 (0x00519000)
         libgcc_s.so.1 =>  /lib/libgcc_s.so.1 (0x0079d000)
         libc.so.6 =>  /lib/libc.so.6 (0x003b1000)
         libgif.so.4 =>  /usr/lib/libgif.so.4 (0x002bd000)
         /lib/ld-linux.so.2 (0x0038e000)
         libX11.so.6 =>  /usr/lib/libX11.so.6 (0x00110000)
         libXau.so.6 =>  /usr/lib/libXau.so.6 (0x003ac000)
         libXdmcp.so.6 =>  /usr/lib/libXdmcp.so.6 (0x00213000)
         libdl.so.2 =>  /lib/libdl.so.2 (0x004f9000)

What I noticed now though, is that the output generated by my php-script,
doesn't show the error which is generated by pdf2swf. When I execute pdf2swf
in the shell, it shows:

address@hidden eric]# pdf2swf -vv -T9 LB5a_Compl_FC.pdf -o
/eric/pdf2swftest/LB5a_Compl_FC.swf
VERBOSE setting parameter flashversion to "9"
VERBOSE Generating info structure for page 1
VERBOSE Generating info structure for page 2
Floating point exception

I checked the mailinglist, and I found one similar problem. I'll reply to
that thread too :)

Now, we need to find out what is causing the SIGFPE. I usually use gdb to debug programs.

I will show the simplest possible way to debug pdf2swf, if you want more details, please consult the documentation:

http://sourceware.org/gdb/current/onlinedocs/gdb/

1. Start a gdb session:
gdb /usr/local/bin/pdf2swf [this needs to be the full path to your pdf2swf executable]

2. then at the (gdb) prompt issue:
run <filename>.pdf -o <output>.swf

Can you copy and paste the output. (Please do not include the "(no debugging symbols found)" messages).

3. use the "quit" command to exit the session
