Hello Mr. Olbrich, 

I am trying to include protobuf (http://code.google.com/p/protobuf/) in PTXdist and encountered some problems. I succeeded in adding protobuf to the system library section in PTXdist and the build is started when I do a "pdxdist targetinstall protobuf", but I get the following error:

libtool: link: i686-unknown-linux-gnu-g++ -pthread -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare -O2 -g -DNDEBUG -pthread -Wl,-rpath-link -Wl,/home/developer/PTXdist/OSELAS.BSP-ElacNautik-DL3000/platform-i686/sysroot-target/lib -Wl,-rpath-link -Wl,/home/developer/PTXdist/OSELAS.BSP-ElacNautik-DL3000/platform-i686/sysroot-target/usr/lib -o protoc main.o  -L/home/developer/PTXdist/OSELAS.BSP-ElacNautik-DL3000/platform-i686/sysroot-target/lib -L/home/developer/PTXdist/OSELAS.BSP-ElacNautik-DL3000/platform-i686/sysroot-target/usr/lib -lpthread ./.libs/libprotobuf.so ./.libs/libprotoc.so -lz -pthread

The problem is that the library has been built as a 64bit library (ELFCLASS64), but the target is a 32bit one.

I am using the OSELAS.BSP-ElacNautik-DL3000 and the OSELAS.Toolchain-2011.11.3 on a 64bit Ubuntu 12.04 with ptxdist-2012.09.1 for the BSP and ptxdist-2011.11.0 for the Toolchain.
