[Linux-gpib-general] libgpib.so.0 not found on Debian

[Alexander Bessman]

Hello,


I've been using linux-gpib successfully on Scientific Linux 6 for a while, and recently decided to migrate to Debian instead. However, after compiling linux-gpib 3.2.21 on Debian I am unable to run gpib-config or ibtest due to this error: "ibtest: error while loading shared libraries: libgpib.so.0: cannot open shared object file: No such file or directory"


Indeed, running ldd on /usr/local/bin/ibtest shows the following:


linux-vdso.so.1 (0x00007ffd3edf2000)
libgpib.so.0 => not found
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f5540a73000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f55406c9000)
/lib64/ld-linux-x86-64.so.2 (0x00007f5540cbf000)


Which is odd, because /usr/local/lib/libgpib.so.0 exists and /usr/local/lib is in my library path.


I've tested this on both Debian Wheezy and Debian Sid with the same result.


Has anyone encountered this problem before, or have any ideas as to what might be the cause?

Hi
Did you install the kernel headers?
apt-get install linux-headers-$(uname -r)

and other packages that migth be needed:
apt-get install kernel-package libncurses5-dev fakeroot wget bzip2
build-essential.

To patch a running Kernel often makes problems, I usually in this case
download a vanilla Kernel from kernel.org, compile over night "the
Debian way" (ask google how to) and linux-gpib runs smoothly....

BTW: Don't use Debian unstable, unless you know what you are doing.
And Debian Jessie will be released soon;)

Regards

I have just built current trunk on my wheezy 32bit
Svn At revision 1624.

I have no problems

I did a build for a Raspberry w. an Agilent-USB GPIB adapter , or the
100% compatible Beiming USB-GPIB.

That build is excatly the same as for a 386' machine , except the
additional boot config.txt modification on the RasPi.

You could use that as a guideline.


6: apt-get install linux-headers-$(uname -r)

6a: Install the needed system packages , in order for linux gpib to build
(i might be a bit generous here , it's the same packages used for making
avr-gcc , but hdd space is cheap)


python-dev is nescary for linux-gpib py support

#All packages on one line
sudo apt-get install build-essential texinfo texi2html libcwidget-dev
tcl8.4-dev tk8.4-dev libncurses5-dev \
libx11-dev binutils-dev bison flex libusb-1.0-0 libusb-dev libmpfr-
dev libexpat1-dev tofrodos subversion autoconf automake libtool python-dev


7: mkdir linux-gpib (we assume in your home dir)
8: cd linux-gpib
9: svn checkout svn://svn.code.sf.net/p/linux-gpib/code/trunk linux-gpib-
code

11: cd linux-gpib-code/linux-gpib/
12: ./bootstrap
13: ./configure
14: make | tee make.log
15: sudo make install | tee imake.log

16: sudo modprobe agilent_82357a
17: sudo gpib_config

Do some udev magic , maybe be a groupmember of gpib , and you should be
good to go.

Once I had a similar problem. Running ldconfig fixed it.
Anyway, the problem should disappear after a reboot.

Also check:
libgpib is correctly compiled for 64 bit system?
libgpib.so.0 is a link; check the file it points to.
