How to get rid of __ALIGN(4) syntax error in Eclipse?

[Andy]

Hello,

I'm working with FDS and I have declared a variable like this:

__ALIGN(4) static uint32_t data;

My code compiles and works correctly but Eclipse complains about the __ALIGN(4) and highlights it as a syntax error and shows errors everywhere where I use that variable, which is very frustrating.

I know this is an Eclipse issue, but I'd really appreciate it if someone could help me get rid of that annoying error. Is there any file I can include or anything I can do about it?

Hi,

There is a header file called compiler_abstraciton.h located in SDK_folder\components\device . Inside it there are a bunch of redefines. Have you included this header file in your project? Do you know if the correct redefine is being used?

Hi Martin, I checked and explicitly added the file to the project (for Eclipse to index it) but it still shows up as an error. I see the `__ALIGN()` macro definition there, but it's not being used because somehow Eclipse says `defined(__GNUC__)` is false. Any suggestions?

Hi,

Please make sure to enable CDT ARM Cross Built-in Compiler Settings in your project properties:

and that __GNUC__ is included here:

Hi Martin,

I just checked and the entry list in CDT ARM Cross GCC Built-in Compiler Settings is empty. I do have it "checked" but in the Entries menu it doesn't show anything.

Hi,

Please make sure to stand at "source code level":

Then make sure to check "CDT GCC Built-in Compiler Settings Cross ARM:
