why does jpeg_decompress_create crash without error message?

I've a problem with just this sample of code :

struct jpeg_decompress_struct cinfo;
struct jpeg_error_mgr jerr;

cinfo.err = jpeg_std_error(&jerr);

jpeg_create_decompress(&cinfo);

My program exits on jpeg_create_decompress without error message. Any one have an idea ?

I found the solution !

On Android, there is already a libjpeg.so installed and it appears it is loaded in priority. This one seems to be configured differently. So, you have to rename your shared library libjpeg into a different name.

For me, i renamed from libjpeg.so to libmyjpeg.so.

You should have been doing:

struct jpeg_decompress_struct cinfo;
struct jpeg_error_mgr jerr;
cinfo.err = jpeg_std_error(&jerr); // <<-- cinfo here!
jpeg_create_decompress(&cinfo);
