This seems strange because:

#ifdef HAVE_GCRYPT
#include <gcrypt.h>
#endif

in gvfsbackendafpbrowse.c.

Maybe there's a mis-detection of the gcrypt on your host and we need to
make sure gvfs doesn't try to detect gcrypt when it is not part of the
enabled packages. I am quite sure I did a build of gvfs 1.16.2 without
gcrypt support, but the machine didn't had the gcrypt development files
installed in the distribution.

Thanks,

Thomas

Hi Thomas,

I will have a look in the build files. I have libgcrypt installed on
the host so maybe it detects this one and fails.

Indeed, it seems the host libgcrypt is picked if there is not one for the target

configure:18751: checking for mips-buildroot-linux-uclibc-libgcrypt-config
configure:18784: result: no
configure:18794: checking for libgcrypt-config
configure:18812: found /usr/bin/libgcrypt-config
configure:18824: result: /usr/bin/libgcrypt-config
configure:18836: WARNING: using cross tools not prefixed with host triplet

I will have a look on how to fix this
