Hello ,
I am trying to statically build uclibc using buildroot to use it to cross
compile mpich . when I generate uclibc toolchain using make menuconfig the
executables in output/usr/host/bin are dynamically linked .
do I have to build uclibc from output/build/toolchain folder in order to
get the statically linked executables .
I'm new to this if I'm missing something kindly direct me .
Regards,
Doha

Are you sure you have enabled BR2_STATIC_LIBS=y ?
Which Buildroot version are you using ?

Dear Thomas Petazzoni ,
I'm using buildroot-2015.02 and yes BR2_STATIC_LIBS is enabled here is
the defconfig file :
BR2_arm=y
BR2_STATIC_LIBS=y
BR2_GCC_ENABLE_OPENMP=y
BR2_ECLIPSE_REGISTER=y
Regards,
Doha

output/usr/host/bin contains executables for the host. These are linked
dynamically and have an rpath setting to make sure the correct libraries are
found in output/usr/host/lib.
The executables on the target (output/target and output/images) should be
statically linked.
There is no way in buildroot to link the host binaries statically.

So in order to use the generated uclibc to cross compile mpich (and link
everything statically) I have to extract the rootfs.tar and use it to
statically build the mpich is that correct ?
Regards,
Doha.

No: Buildroot does not generate a development environment for the
target (i.e we don't build a compiler).
Instead, you should create a Buildroot package for mpich, so that it
gets cross-compiled as part of the Buildroot build. See the Buildroot
manual for all the details about adding a new package.
Best regards,
Thomas
