Detailed description of the problem

hi, scilab have problems with libs,

first one is bug #3854 even if i fixed it, other problems still exist and i want to report them:


1st) it link to *.so files, that means they are DEVELs not installed bye default and used only to link libraries.

example: fftw3 module need libfftw3.so, but should be linked to libfftw3.so.3

even if i'm not sure, if my patch is enought i think i fixed it... patch attached

2nd) scilab  search libraries where NOT exist, when IT installed in another directory,

example: 

 !--error 999 
Impossible to load libsciscicos.so library: /usr/share/scilab//modules/scicos/.libs/libsciscicos.so: cannot open shared
object file: No such file or directory
at line      19 of function do_load called by :  
line   283 of function scicos called by :  
line    16 of function scicos_demostration called by :  
scicos_demostration(thispath+"/bounce.cosf");
line     9 of exec file called by :    
mo_gui_update();exec(script_path,-1);;if exists("%oldgcbo") then gcbo = %old
while executing a callback


the file does not exist (the hidden directory  /usr/share/scilab//modules/scicos/.libs does not exist) but:

Hp-Linux:/usr/lib/scilab # locate libsciscicos.so
/usr/lib/scilab/libsciscicos.so
/usr/lib/scilab/libsciscicos.so.5
/usr/lib/scilab/libsciscicos.so.5.0.0


the file was installed with "make install" in /usr/lib/scilab (the place is right, but scilab search the lib in a wrong
path

same problem with ALL "libsci*" libraries... scilab search them in 

 /usr/share/scilab//modules/<module-name>/.libs direcotry but all libs are in /usr/lib(64)/scilab or in /usr/lib(64) if
scilab is compiled with shared

Text of the scilab error message

everything is attached

Steps to reproduce the bug

Created an attachment (id=950) [details]
libfftw3 patch

compile scilab from source and lunch some demos

------- Comment #1 From Andrea 2008-12-14 23:10:10 -------

errors displayed into scilab console

i printed to file everything was printed in scilab console...

here the list of all files (libraries) available in /usr/lib/scilab, you are now able to check that all lib searched in

------- Comment #3 From Andrea 2008-12-15 12:03:38 -------

any news?

at least, could you please tell me where is definided to search libraries in

 /usr/share/scilab//modules/<module-name>/.libs directory?

thanks

------- Comment #4 From Sylvestre LEDRU 2008-12-15 13:50:06 -------

1) Thanks. Commit 673a5d97ced61a87160128a1b903590e0b98a8f9 in the branch 5.0 (will be reported to the master soon)

2) It should not use this directory. I didn't see this bug before. I have a look.

------- Comment #5 From Andrea 2008-12-15 14:05:02 -------

maybe my configure may help:

./configure --with-tk-library=%{_libdir} \
        --with-tcl-library=%{_libdir} \
        --with-blas-library=%{_libdir} \
        --with-lapack-library=%{_libdir} \
        --with-jdk=%{java_home} \
        --enable-shared \
        --disable-static \
        --with-gfortran \
        --with-gcc \
        --with-ocaml \
        --with-fftw \
        --enable-build-localization \
        --enable-build-help \
        --with-install-help-xml \
        --with-docbook=/etc/xml/docbook-xsl-stylesheets-1.73.2.xml \
        --enable-build-swig \

        --with-x \

        --with-umfpack-include=/usr/include/suitesparse

------- Comment #6 From Sylvestre LEDRU 2008-12-15 14:14:03 -------

I am not sure it is related but why you are not using --with-prefix ?

------- Comment #7 From Andrea 2008-12-15 15:10:49 -------

because in rpms spec file, use the macro %configure is the same to give (on 32bit hosts) :

./configure
--host=i686-pc-linux-gnu
--build=i686-pc-linux-gnu
--target=i586-suse-linux
--prefix=/usr
--exec-prefix=/usr
--bindir=/usr/bin
--sbindir=/usr/sbin
--sysconfdir=/etc
--datadir=/usr/share
--includedir=/usr/include
--libdir=/usr/lib
--libexecdir=/usr/lib
--localstatedir=/var
--sharedstatedir=/usr/com
--mandir=/usr/share/man
--infodir=/usr/share/info


the problem any way is not the prefix, scilab search libs in

 /usr/share/scilab//modules/<module-name>/.libs directory and not in

/usr/local or any other prefix related path...

i'm looking on /usr/share/scilab/etc files but i'm not able to find thing.

------- Comment #8 From Sylvestre LEDRU 2008-12-15 15:30:50 -------

ok, thanks

Could you try with this patch:
http://svn.debian.org/viewsvn/debian-science/packages/scilab/trunk/debian/patches/librarypath.diff?rev=35236&view=markup

We are doing a simple dlopen. If it can find it in the LD_LIBRARY_PATH, it tries againt an hardcoded path for the dev
env.

------- Comment #9 From Andrea 2008-12-15 15:53:14 -------

i'm trying... scilab is compiling right now...

btw

i found in /usr/share/scilab/etc/librarypath.xml that:

.... cat .....
<!-- Developpement environment -->
<path value="$SCILAB/modules/action_binding/.libs"/>
<path value="$SCILAB/modules/console/.libs"/>
<path value="$SCILAB/modules/history_manager/.libs"/>
<path value="$SCILAB/modules/completion/.libs"/>
<path value="$SCILAB/modules/localization/.libs"/>
<path value="$SCILAB/modules/renderer/.libs"/>
<path value="$SCILAB/modules/graphic_export/.libs"/>
<path value="$SCILAB/.libs"/>
.... cat .....

as you can see it looks to be default scilab behavior...

the problem are 2 any way..

1st) as told 

$SCILAB/modules/<module-name>/.libs

directory does not exist..

2nd) no libs should be installed in /usr/share/.. (and scilab DOES NOT install there) so it is a wrong place to search
libraries any way....

libraries should alway be in /usr/lib(64) (and subfolders) and/or in /usr/local/lib(64) and subfolders

------- Comment #10 From Sylvestre LEDRU 2008-12-15 16:05:08 -------

Stuff in etc/librarypath.xml is not used by the dynamic load (maybe this is an error)

1) I know and it is normal. .libs/ is used by the developer who are working on Scilab. In this case, data & libs are in
the same tree ($SCILAB).
Therefor the 2) is obsolete.

------- Comment #11 From Andrea 2008-12-15 17:04:04 -------

well.. debian patch fix the problem thanks

------- Comment #12 From Sylvestre LEDRU 2008-12-15 17:06:47 -------

You are welcome (btw, I am the author of the debian package)
Thanks for testing.
