Hello,
 i'm trying to cross compile mpich , I have extracted mpich-3.1.3 the I created a folder name build inside it . In order to statically build mpich I used the following commands:

export CC="/home/doha/buildroot-2015.02/output/host/usr/bin/arm-linux-gcc"
export AR="/home/doha/buildroot-2015.02/output/host/usr/bin/arm-linux-ar"
export CFLAGS="-march=armv5te -static -I/home/doha/buildroot-2015.02/output/host/usr/include/"
export LDFLAGS="-L/home/doha/buildroot-2015.02/output/host/usr/lib/"


cc=/home/doha/buildroot-2015.02/output/host/usr/bin/arm-linux-gcc ./configure --prefix=/home/doha/mpich-3.1.3/build/ --host=arm-linux  --disable-shared --with-pm=hydra --with-device=ch3:nemesis --disable-fortran


but nothing appears in the build folder while it shows no errors on the terminal
