I'm trying to install SciLab.

I've downloaded source code tarball, unpacked it and run :

./configure

which says.....

checking for tcl library tcl8.5... configure: error: header file tcl.h has been found for 8.4* but no corresponding tcl library (ie libtcl8.4.so)



If search for libtcl8.4.so in Add/Remove software repositories, I can't see it anywhere or any relevant tcl libraries.

Any suggestions please.

try installing tcl8.x-dev

Apart from that scilab is in the repositories - are you sure you need to install from source?

Check where the tcl package has installed the shared library:
and see if it is in the library cache:
otherwise the RPM package can be broken or the system did not update the library cache correctly. If you find out that the tcl library is not in a standard place or does not appear in the cache, usually you can specify the correct location using some option of the configure script. Or eventually add the path to the library using the LDFLAGS environment variable and specify the library name using LIBS. Look at
to see which is the more suitable solution to the software you're going to compile. Another option is to update tcl to version 8.5, if the package is available for your system.

Edit: the configure script of scilab accepts the --with-tcl-library=DIR option.

Thanks for replies.

klearview, I can't find scilab in my repository, although I know that the search doesn't always programs that I know are in the repository, but, anyway, I can't find it.

colucix, this is what I get :

$ rpm -ql tcl | grep lib
/usr/lib64/libtcl8.5.so
/usr/lib64/tcl8.5

$ /sbin/ldconfig -p | grep libtcl
libtcl8.5.so (libc6,x86-64) => /usr/lib64/libtcl8.5.so

$ echo $LDFLAGS

$



Therefore, do I need to do :

$ ./configure LDFLAGS="-L/usr/lib64"

Hmmm... given the output of the suggested commands, apparently there is no reason why the scilab configuration should not find the tcl library, unless scilab is a 32-bit application and is looking for the 32-bit version of libtcl. You can try to install it. If the Add/Remove Software is not able to find the tcl packages for the reason you will investigate later, you can try
from the command line and see if a 32-bit version is available for your system.

$ yum list SciLab
Loaded plugins: refresh-packagekit
Error: No matching Packages to list

$ yum list scilab
Loaded plugins: refresh-packagekit
Error: No matching Packages to list
[pp@localhost scilab-4.1.2]$


.........so I think there is no SciLab.




$ yum list tcl tcl-devel
Loaded plugins: refresh-packagekit
Installed Packages
tcl.x86_64 1:8.5.2-2.fc9 installed

Available Packages

tcl-devel.i386 1:8.5.2-2.fc9 updates


....Is tcl.i386 32-bit ?
....Can I have 32-bit and 64-bit both installed at the same time ?

Yes and yes!

Having 32-bit and 64-bit libraries installed at the same time is possible, since they will be placed in different directories, e.g. /usr/lib vs. /usr/lib64, and the library cache will take in account the difference. As demonstrated by the error in ./configure.

Please note that mine was just a guess. I mean scilab being a 32-bit application. Anyway you can give it a try and eventually (if still not works) uninstall the 32-bit version of tcl.

Okay, thanks for your help, colucix

./configure works without errors.


...so thanks for your help.

make

...doesn't quite work and gets stuck at a memory allocation problem. Not sure what to do about this.

Please, post the exact error message. Or eventually start a new thread about this new problem for a better exposure.

Sorry - I thought you were using Ubuntu (that's what your profile says). SciLab is in Ubuntu's repos.
