error while building build_caffe.sh

[gaurav16gupta]

As there is not support using hdf5. How can build without it ?

Hi @stark123,
In my caffe fork, hdf5.h is used only with USE_HDF5 set, refer to https://github.com/sh1r0/caffe/blob/cmake_android/include/caffe/util/hdf5.hpp. If you would like to build your own caffe, you could refer to my commits and patch it by yourself. BTW, although I'm willing to help you, I have little time to deal with the issues, and I think you should provide more details (e.g., your setups, custom builds?) in your issues (i.e., #73, #74, and this one).
Thanks.

@sh1r0 I am trying to build this with hdf5 support
getting include error for

I have checked out cmake_android branch

I have tried solution provided on this issue
can't find hdf5.h when build caffe

Created libhdf5.so and libhdf5_hl.so symlinks

Added path for hdf5.h in caffe-android-lib/caffe/Makefile as follows

INCLUDE_DIRS := /usr/local/include /usr/include/hdf5/serial/
LIBRARY_DIRS := /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/ 

as it has header files for hdf5 which are need to build caffe

caffe-android-lib $ ls /usr/include/hdf5/serial/ | grep hdf
hdf5.h
hdf5_hl.h
hdf5.mod

Still getting include error for
#include "hdf5.h"

Am I missing something?
