i386 libc6 library "could not read symbols: File in wrong format"
 

I accepted a fishy update to my x64 Debian Wheezy and due to some conflicts it removed some files like libpthread.so from the i386-linux-gnu directory. I reinstalled libc6:i386 and took some packages off the internet and linked them by hand.
Now I am left with the error on the subject. I found librt.so from Debian packages. Downloaded and linked it. Here is the build output:

Any suggestion is appriciated.

I don't undertand. You say you are running Wheezy and yet you have libc version 2.19 installed? Jessie uses 2.19 but Wheezy uses 2.13. That's going to cause lots of problems. I don't understand what "I accepted a fishy update to my x64 Debian Wheezy". Who did you accept it from? Don't you use normal Debian repositories for updating your software? What does your /etc/apt/sources.list file look like?
Oh and shouldn't you be using a 3.2 kernel for Wheezy. I checked and the 2.6 is in the oldlibs subsection and is just a dummy package.
jdk

probably I missed something, you used mipsel-linux-gcc as compiler and tried to link i386 libs. That will not work (if I understand it well), that's why you got this message: could not read symbols: File in wrong format

Hi,

I have x64 and when I installed gstreamer:i386 2.19 must have came along with it.

As fishy update I mean an official one. It showed lots of conflicts and removed 186 MB of libraries.

Can you please help me understand how libc6:i386 and libc6:amd64 can conflict? There is the chance that both are using /usr/lib and files in that directory will get replaced(In that case installer should distinguish the system compiler and cross compiler). What are the other reasons?

By the way, I also have a mipsel toolchain in a separate directory. I ran #find -name librt. It does not exist in the toolchain. So if the application wants those libraries the only source is i386.

Thanks for the reply. That baffled me too. This build worked before I recieved an update. I have a separate toolchain for mipsel and it does not include the libraries. I asked a fried who is able to compile to give me a verbose build log. I will post it. There is the weak chance that makefile is pointing to wrong directory.

I forgot to mention that I also tried 2.13 and failed miserably.

you can check with the command file not only the libs but the archives and object files too: file MediaTransportMain.o or file Decoder.a.

It turns out that error was caused by a unit test which explains the linking of i386 libraries. We get this from a third party software company. This was an error in the build script. Thanks for helping. Now that this thread is moot, how should I edit the title?

I would rather set it to solved and open another if you have additional questions
