Subject: Re: [OMPI devel] [EXTERNAL] OpenSHMEM round 2
From: Ralph Castain (rhc_at_[hidden])

Turning off the enable_picky, I get it to compile with the following warnings:

pget_elements_x_f.c:70: warning: no previous prototype for 'ompi_get_elements_x_f'
pstatus_set_elements_x_f.c:70: warning: no previous prototype for 'ompi_status_set_elements_x_f'
ptype_get_extent_x_f.c:69: warning: no previous prototype for 'ompi_type_get_extent_x_f'
ptype_get_true_extent_x_f.c:69: warning: no previous prototype for 'ompi_type_get_true_extent_x_f'
ptype_size_x_f.c:69: warning: no previous prototype for 'ompi_type_size_x_f'

I also found that OpenShmem is still building by default. Is that intended? I thought you were only going to build if --with-shmem (or whatever option) was given.

Looks like some cleanup is required
