jacklund / libgatt Goto Github PK

I performed the following:

sudo apt-get install glib2.0
git clone https://github.com/jacklund/libgatt.git
cd libgatt
./configure
make

make  all-am

Am I missing some dependency?

I was cross-compiling your libgatt for a MIPS processor under openWrt. I was getting an error with the att.h header file where it could not find "bluetooth/uuid.h". I've noticed it is the only header file that sets the path to "bluetooth/uuid.h" instead of just "uuid.h". WIth that change it cross-compiles successfully on my side.

It is not clear whether gatt library refers to bluez header files such as sdp.h or its own; especially that not all the header files available in src folder of the gatt library and required for compilation, are installed in /usr/local/include/gatt.

On Ubuntu 16.04, the libbluetooth-dev 5.37 package does not include the header file bluetooth/uuid.h, which precludes using libgatt due to references to this file.

It seems that the upstream BlueZ project made this header file private back in 2013, renaming it to lib/uuid.h:
https://www.spinics.net/lists/linux-bluetooth/msg33107.html

This probably means that the header file will need to be included in the libgatt repository for the library to be usable with newer versions of BlueZ?

Hello, I have a simple request. Are there any examples you can provide of the use of this library I could use as reference?

Thank you!

Linker was failed with undefined reference:

undefined reference togatt_read_char(GAttrib, unsigned short, void ()(unsigned char, unsigned char const, unsigned short, void_), void*)'`

libgatt configure prefix = /usr/local
libgatt lib: -L /usr/local/lib -lgatt

Something wrong with my libgatt build?
