Hi,
I'm a beginner in zeromq. i want to integrate zeromq with json rpc on beagleboard. for that first of all installed the zeromq library into my PC by issuing the following commands
git clone git://github.com/jedisct1/libsodium.git
cd libsodium
./autogen.sh
./configure && make check
sudo make install
sudo ldconfig
cd ..
git clone git://github.com/zeromq/libzmq.git
cd libzmq
./autogen.sh
./configure && make check
sudo make install
sudo ldconfig
cd ..
After installation i compile the attached zeromq.c file using command
gcc -o zeromq zeromq.c -lzmq
which produced a zeromq executable file successfully.
i compiled the same c in eclipse tool also sussccessfully.
but for beagleboard integration we are using gcc-linaro-arm-linux-gnueabihf-4.8-2013.07-1_linux toolchain.
so whenever giving this tool in eclipse it shows following error on console
arm-linux-gnueabihf-gcc -L/usr/local/lib -o "zeromq" ./src/zeromq.o -lzmq
/usr/lib/gcc/arm-linux-gnueabihf/4.6/../../../../arm-linux-gnueabihf/bin/ld: skipping incompatible /usr/local/lib/libzmq.so when searching for -lzmq
/usr/lib/gcc/arm-linux-gnueabihf/4.6/../../../../arm-linux-gnueabihf/bin/ld: skipping incompatible /usr/local/lib/libzmq.a when searching for -lzmq
/usr/lib/gcc/arm-linux-gnueabihf/4.6/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lzmq
collect2: ld returned 1 exit status
make: *** [zeromq] Error 1
so i tried to compile the same file on terminal, which also produced the same error.
later i tried to install the zeromq library with different configuration commands as follows.
./configure --host=arm-linux-gnueabihf
./configure --host=arm-linux-gnueabihf --with-libzmq=/usr/local/lib
but at his time it produces the errors as follows.
checking zmq.h usability... yes
checking zmq.h presence... yes
checking for zmq.h... yes
checking for zmq_init in -lzmq... no
configure: error: cannot link with -lzmq, install libzmq.
here what may be the problem? how can i resolve it?
Thanks in advance
