Hello,

I used buildroot to statically compile MPICH2-1.3 for ARM devices using the following commands:

export CFLAGS="-I/home/doha/buildroot-2015.05/output/host/usr/include/ -DHAVE_DEPRECATED_DNS_FUNCS -fPIC -march=armv5 -mfpu=vfp -O3"

export LDFLAGS="--static -L/home/doha/buildroot-2015.05/output/host/usr/lib/ -fPIC"

cc=/home/doha/buildroot-2015.05/output/host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc ./configure --prefix=/home/doha/mpich/build/ --host=arm-linux --disable-shared --enable-static --with-pm=smpd --with-device=ch3:sock --disable-f77 --disable-fc

when I compile the code using android ndk I get the following error

I want to know what I'm missing and why it is not linking properly
