HDF5 Libraries

[Nobody/Anonymous]

Hi all
Does anyone study HDF5 libraries with DEVC++ on windows?
I could not manage to link to lib files given by HDF group.
I want to use HDF5 libs with DEVC++ but could not manage.
Thanks for advance

Well, a good place to start would be to:

(1) Tell us exactly what those libraries are for
(2) Where you got them from (and exactly what you downloaded)
(3) Post your "Basic 3" for a simple as possible example program.
(The Basic 3 are covered in the thread (which you should have read
already) titled "Please Read Before Posting a Question.

It is especially important by the way to start from the beginning,
and be thorough if you have done a forum search (which you should
ALWAYS do before asking a question) and found nothing on a topic,
implying that the chances are pretty good that no one has worked
with the library that you are interested in.

The fact that no one has used it is not neccessarily a show stopper,
but it does imply that you need to provide the basic information
needed for someone to follow in your footsteps, and help you out
with pertinent information.

Hi wayne
1-HDF5 is an image storing format developed by hdf group and home page is
http://hdf.ncsa.uiuc.edu/
2-i have downloaded from http://hdf.ncsa.uiuc.edu/HDF5/release/obtain5.html
3-

include <stdlib.h>

include <hdf5.h>

int writeUCharData(char fname, char dsetname)
{

hid_t fid=-1, dataspace_id=-1, dataset_id=-1;
hsize_t dims[2];
hid_t status=-1;

if(filetype(fname) == SIMPL){
if((fid = H5Fopen(fname, H5F_ACC_RDWR, H5P_DEFAULT)) < 0)
fid = H5Fcreate(fname, H5F_ACC_TRUNC, H5P_DEFAULT, H5P_DEFAULT);
}
else
fid = H5Fcreate(fname, H5F_ACC_TRUNC, H5P_DEFAULT, H5P_DEFAULT);

dataspace_id = H5Screate_simple(2, dims, NULL);

if(filetype(fname) != SIMPL){
dataset_id = H5Dcreate(fid, dsetname, H5T_NATIVE_UCHAR, dataspace_id, H5P_DEFAULT);
}
else{
if((dataset_id = H5Dopen(fid, dsetname)) < 0)
dataset_id = H5Dcreate(fid, dsetname, H5T_NATIVE_UCHAR, dataspace_id, H5P_DEFAULT);
}

return status;

}

Now, I see no MinGW build on the page you referenced.

Did you assume that this one would work with MinGW?

Windows
Compilers: MSVC++ 6.0, .NET 2003

Assuming that a Visual C++ compiled library will work with the MinGW/GCC
environment is not a good assumption. Worse than "it never works", sometimes
it does work, sometimes it doesn't.

p.s. I did a quick google between things on the honey-do list yesterday
evening and found some references to having to build this library from
source using MinGW/MSYS. This may not be a big deal, but I did not have
a lot of chance to look further.

Hi, I would like to use HDF5 libraries inside the Dev-c++ environment. I think the best will be to compile the source code. Has anyone did that already? Is there any package for hdf5 libraries?

Thanks,
