Hi all,
I managed to install ldd on my device, and the results show nothing wrong that
I can see:
# ldd librxtxSerial.so
libpthread.so.0 => /lib/libpthread.so.0 (0x00000000)
libc.so.0 => /lib/libc.so.0 (0x00000000)
/lib/ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x00000000)
# ls /lib/libpthread.so.0
/lib/libpthread.so.0
# ls /lib/libc.so.0
/lib/libc.so.0
# ls /lib/ld-uClibc.so.0
/lib/ld-uClibc.so.0
# pwd
/var/lib/fluid/osgi-config/bundle9/version0.0/lib/native/linux/mips
Does anybody know if I can get more information out of Felix?
Does anybody know if the following message:
ERROR: JarContent: Unable to create library directory.
is coming from Felix? If I try to install the bundle interactively, it fails
and that is one of the messages. As far as I can tell, I cannot easily get the
source code for the Felix framework to check myself (although I can download
the source code of bundles from http://felix.apache.org/site/downloads.cgi,
just not for the framework itself).
Any help appreciated,
Matt

Hi Chris,
As it happens, the device does not have ldd installed. I am looking into
getting the source code for ldd, but in any case thank you for your response.
Cheers,
Matt

Subject: Re: Cannot load native library
I could be mistaken, but IIRC you can also get this error if the library is
linked against another lib that is missing. On linux you can usually figure
these out with ldd.
ldd -v
/var/lib/fluid/osgi-config/bundle9/version0.0/lib/native/linux/mips/librxtxSerial.so
Not sure if you have that option on your device, but it might be worth a
try.
Chris
