Double braces + using the github code worked. Thanks.

Try this blog post, much easier to setup and work with Elcipse + GCC. embeddedsoftdev.blogspot.ca/.../ehal-nrf51.html

You should have a look at the makefile in the project I linked to in my answer. There are probably some missing files or incorrect paths in your makefile.

Yes thanks, that solves the missing braces error. Now, I get a ton of undefined reference errors. Any suggestions? Sorry, I'm new to eclipse + GCC:

Thanks for giving an explanation of the warning!

It's gcc being picky, but correct

typedef struct {
    unsigned char uuid128[16];
} ble_uuid128_t;

You need braces for the initialisation of the unsigned char array and you need braces for the initialisation of the structure too. Hence you need 2 sets of braces for a valid initialiser.

Hi, don't have a good explanation of why GCC complains about missing braces. However, adding extra braces seems to fix the problem:

ble_uuid128_t nus_base_uuid = {{0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0,  0x93, 0xF3, 0xA3, 0xB5, 0x00, 0x00, 0x40, 0x6E}};

EDIT: There's is also a ble uart example on github with GCC makefile included.
