libz.so: could not read symbols: File in wrong format

[Martin Herrman]

All,

although not new to linux or compiling software (e.g. kernel, seldom used
apps, running Gentoo), I'm new to cross-compiling and need some help :-)

What is it that I want to accomplish? Create a new custom firmware for my
mediaplayer (EM7075).

What did I do so far?

1. install mips-4.3.51-mips-linux-gnu.bin, typical install, location:
/root/CodeSourcery
2. Modify .bash_profile (I do realise that this impacts all my compilations
on Gentoo :-))

martindesktop ~ # cat /root/.bash_profile

# New environment setting added by Sourcery G++ Lite for MIPS GNU/Linux on
Fri May 14 10:16:00 CEST 2010 1.
# The unmodified version of this file is saved in
/root/.bash_profile254443263.
# Do NOT modify these lines; they are used to uninstall.
PATH="/root/CodeSourcery/Sourcery_G++_Lite/bin:${PATH}"
export PATH

the error)

3. download, gunzip and untar zlib-1.2.5.tar.gz
4. ./configure --prefix=/root/EM7075/mips; make; make install
5. download, gunzip and untar openssl-1.0.0.tar.gz
6. ./Configure dist --prefix=/root/EM7075/mips zlib
--with-zlib-include=/root/EM7075/mips/include
--with-zlib-lib=/root/EM7075/mips/lib
7. when executing 'make', the following error pops up:

8. libz.so is a symlink to libz.so.1.2.5
martindesktop openssl-1.0.0 # file /root/EM7075/mips/lib/libz.so
/root/EM7075/mips/lib/libz.so: symbolic link to `libz.so.1.2.5'
martindesktop openssl-1.0.0 # file /root/EM7075/mips/lib/libz.so.1.2.5
/root/EM7075/mips/lib/libz.so.1.2.5: ELF 32-bit LSB shared object, MIPS,
MIPS32 rel2 version 1 (SYSV), dynamically linked, with unknown capability
0xf41 = 0x756e6700, not stripped

9. nm shows the symbols:
martindesktop openssl-1.0.0 # nm
/root/EM7075/mips/lib/libz.so.1.2.5

00000000 A
ZLIB_1.2.0

(..)

martindesktop openssl-1.0.0 #
/root/CodeSourcery/Sourcery_G++_Lite/bin/mips-linux-gnu-nm
/root/EM7075/mips/lib/libz.so.1.2.5
00000000 A ZLIB_1.2.0
(..)

10. I have replaced the symlink with the original libz.so.1.2.5, makes no
difference (as expected).

11. looked into the known problems file inside the tar.gz, but no luck.

12. I expect that this could be a 32/64-bit issue, or an incompatibility
issue (openssl 1.0.0 depends on zlib < 1.2.5?), but I'm clueless..

I hope someone can help me solving this issue, much thanks in advance!
