Dear All,

I am installing EMBOSS on my UBUNTU system. I follow ./configure, make and make install. At make install step, there is an error appearing as follows: error while loading shared libraries: libnucleus.so.6: cannot open shared object file: No such file or directory

I am asking Biostar members how to resolve this problem. THANKS very much!!

I had this same problem today, and the available responses to the question did not help. I finally figured it out after some struggle. I though I should share the solution, in case someone else stumbles across this page. The EMBOSS installer does not refresh the library load cache, and therefore the installed libraries are not visible. The fix is to execute the following command as root after make install:

ldconfig


At this point one can run make install one more time just to make sure everything is OK.

Thanks Paul, your fix is the only one that worked for me as well...(for the install from source of course)

If you don't need the latest and greatest, it's as simple as:

sudo apt-get install emboss


Otherwise, libnucleus.so.6 is found in the emboss-lib package so:

sudo apt-get install emboss-lib


That should install to /usr/lib/emboss/lib/.

Installing a package managed library and then installing a built from source version is not a good idea. As well as version mismatch issues this can cause problems with package dependencies. It is best to either use the packages or build from source, when installing to system locations (e.g. /usr/ or /usr/local/).

That said if you need to have both the package managed version (say to handle package dependencies, or provide specific features) and a source build (to provide a specific version, to test a new version, to have the latest version or to support development), you can do this as long as you install the source based build to a local installation location using the '--prefix=location' option to configure. For example I typically install source based EMBOSS builds into '$HOME/usr/EMBOSS-version', so I can have multiple versions available (handy when working out if a specific behaviour is a bug), while still using the Debian med EMBOSS packages by default. ADD REPLY 0 Entering edit mode Yes, I retract the second part of that answer - mix and match not a good idea. I think you just need to clean up and start again as Hamish suggests. I have never had a problem with EMBOSS install on any Ubuntu machine. It sounds like you are dealing with "your own local mess", which is always difficult for others to troubleshoot :) ADD REPLY 0 Entering edit mode i run sudo apt-get install emboss-lib, and then make install, finally make installcheck. There are two minor errors: runJemboss.sh does not support *[installchekc-binSCRIPTS] error1 Leaving directory 'xxx/jemboss' * [installcheck-recursive] error1 leaving directory 'xxx/jemboss' . So it seems i cannot run jemboss package, do you think it a minor error? THANKS!! ADD REPLY 4 Entering edit mode 8.9 years ago Hamish ★ 3.2k That error suggests that 'libnucleus' failed to build correctly. This implies that you are either missing a build dependency (and 'configure' has not omitted it correctly), or your configuration flags are not appropriate. So your first step is to clean-up your build: make distclean  Now configure the build again: ./configure  Using any desired flags, for example: • Specify the installation location: --prefix=$HOME/usr/EMBOSS-6.6.0
• Disable MySQL support: --without-mysql
• Disable Postgres support: --without-postgresql
• Disable support for SOAP web services (requires Axis2/C): --without-axis2c
• Disable PDF graphics output: --without-hpdf
• Disable X11 graphics: --without-x

See the output of './configure --help' for a wide range of other options.

When running 'configure' check the output for expected features being included. For example:

X11 support:

checking X11/Xlib.h usability... yes
checking X11/Xlib.h presence... yes
checking for X11/Xlib.h... yes


PDF support:

checking whether to look for pdf support... yes
checking for HPDF_New in -lhpdf... yes
PDF support found


PNG support:

checking if png driver is wanted... yes
checking for inflateEnd in -lz... yes
checking for png_destroy_read_struct in -lpng... yes
checking for gdImageCreateFromPng in -lgd... yes
PNG libraries found


If these fail it suggests your are missing the associated development packages for the required libraries, so the compiler tests cannot build the sample programs and the feature cannot be used.

Once you have 'configure' producing the desired build configuration, then compile:

make


This will take a little while. If it fails with an error try to run the compile again:

make


And see if the error tells you anything (missing dependency maybe). If the failure is persistent, report it to the EMBOSS developers .

While the basic EMBOSS tests are not that great, it is worth running them to see if you have any serious issues:

make check


Again if this fails try again, if it still fails report to the EMBOSS folks.

Finally if all is well, install to the location specified by '--prefix', or the default '/usr/local/':

make install


Support for EMBOSS is available from the EMBOSS community via the EMBOSS mailing lists, see http://emboss.open-bio.org/html/use/ch03s04.html
