can anyone supply a hint or fix for the binutils ld not finding shared libraries?

Code:
Nokia-N800-26:~# ldconfig -v | grep crypto
        libcrypto.so.0.9.7 -> libcrypto.so.0.9.7
Nokia-N800-26:~# ldconfig --print-cache | grep crypto
        libcrypto.so.0.9.7 (libc6) => /usr/lib/libcrypto.so.0.9.7
Nokia-N800-26:~# ld -lcrypto
ld: cannot find -lcrypto
Nokia-N800-26:~# ls /usr/lib/libcrypto*
/usr/lib/libcrypto.so.0.9.7
Nokia-N800-26:~# ls /usr/lib/libc.*
/usr/lib/libc.a   /usr/lib/libc.so
Nokia-N800-26:~# ld -lc
ld: BFD 2.16.91 20051213 assertion fail /home/ed/su18-2006se-armel-sandbox.gcc34qemu.distcc/work/binutils-2.16.91cs2005q3.2/bfd/elf32-arm.c:2320
ld: warning: cannot find entry symbol _start; defaulting to 00008100
Nokia-N800-26:~#
?

thanks,

rob.

edit:

the problem is with libs that do not end in .so :

Code:
Nokia-N800-26:~/code# ls /usr/lib/libcrypto*
/usr/lib/libcrypto.so.0.9.7
Nokia-N800-26:~/code# cd /usr/lib
Nokia-N800-26:/usr/lib# ld -lcrypto
ld: cannot find -lcrypto
Nokia-N800-26:/usr/lib# ln -s libcrypto.so.0.9.7 libcrypto.so
Nokia-N800-26:/usr/lib# ld -lcrypto
ld: BFD 2.16.91 20051213 assertion fail /home/ed/su18-2006se-armel-sandbox.gcc34qemu.distcc/work/binutils-2.16.91cs2005q3.2/bfd/elf32-arm.c:2320
ld: warning: cannot find entry symbol _start; defaulting to 00008248
Nokia-N800-26:/usr/lib#

I had some errors when i was trying to install g++. A file was missed in the wget step and another one that was downloaded wasn't installed.
Here is the modified script that worked for me.

Code:
wget http://repository.maemo.org/pool/maemo2.2/free/g/gcc-3.4/libstdc++6_3.4.4cs2005q3.2-5.osso3_armel.deb http://repository.maemo.org/pool/maemo2.2/free/g/gcc-3.4/gcc-3.4_3.4.4cs2005q3.2-5.osso3_armel.deb http://repository.maemo.org/pool/maemo2.2/free/g/gcc-3.4/libstdc++6-dev_3.4.4cs2005q3.2-5.osso3_armel.deb  http://repository.maemo.org/pool/maemo2.2/free/g/gcc-3.4/g++-3.4_3.4.4cs2005q3.2-5.osso3_armel.deb  http://repository.maemo.org/pool/maemo3.1/free/binary/libc6_2.3.5cs2005q3.2-5.osso12_armel.deb  http://repository.maemo.org/pool/maemo3.2/free/binary/libc6-dev_2.3.5cs2005q3.2-5.osso12_armel.debhttp://repository.maemo.org/pool/maemo3.1/free/binary/linux-kernel-headers_2.6.16.osso7_armel.deb  http://repository.maemo.org/pool/maemo2.2/free/b/binutils/binutils_2.16.91cs2005q3.2-5.osso1_armel.debhttp://repository.maemo.org/pool/maemo2.2/free/g/gcc-3.4/cpp-3.4_3.4.4cs2

dpkg -i binutils_2.16.91cs2005q3.2-5.osso1_armel.deb
dpkg -i linux-kernel-headers_2.6.16.osso7_armel.deb

dpkg -i cpp-3.4_3.4.4cs2005q3.2-5.osso3_armel.deb
dpkg -i gcc-3.4_3.4.4cs2005q3.2-5.osso3_armel.deb

dpkg -i libstdc\+\+6-dev_3.4.4cs2005q3.2-5.osso3_armel.deb
dpkg -i g\+\+-3.4_3.4.4cs2005q3.2-5.osso3_armel.deb

apt-get -f install
I hope i haven't missed anything.

Thanks rob and i.rachita for the update/fix!

Anyway rob, does that mean that libraries that end in .so will work now? Is it only libcrypto that is affected or are there other libraries that don't end in .so too?

Hi,

This looks brilliant, and i'll try it out soon. Should i consider converting/creating a new partition (efs and jffs2 are mentioned) on my internal memory card for this?

That's really up to you, it takes up 50mb on my uncompressed filesystem. On a jffs2 partition, it should take up a lot lesser.

Agreed. Just followed a modified version to get gcc working on an N800 in OS2008 and it works a treat. Portable c++ development here I come.

Hi,

Then, it's possible to compile a c or c++ app source like in any other linux dist?

I'm thinking that if we have the make utilitie and c/c++ libs, it's possible to make ./configure make make install/or buid package with dpkg utilitie, is it true?

sorry if this is an stupid question, i'm new with the IT, and escuse my poor english.

I would love to see a complete replacement for Scratchbox that runs on the tablet. Plus Glade.

This is way beyond my capabilities to create but I would cheer heartily from the sidelines.

This is so cool. As I read a PDF about C++ using the Evince Document reader, I can try out the examples using SciTE.
