gcc error causes a section type conflict Weirton, West Virginia

Why then doesn't clang fall foul of the same contradiction? Now for the rest of it. The AVR doesn't use the GCC compiler.

Can you zip up the minimal but complete test project and attach it here so htat we can have a look?

Is there a role with more responsibility? That output custom section will contain get_data()::data as a local symbol and inline_get_data()::inline_data as a unique global symbol. Use the preprocessor builtin __COUNTER__ to do this, e.g. #define CAT2(x,y) x##y #define CONCAT(x,y) CAT2(x,y) #define QUOT(x) #x #define QUOTE(x) QUOT(x) #define SET_SECT() __attribute__((section(QUOTE(CONCAT(.custom.,__COUNTER__))))) The point of this is just to Why is RN2903 dropping packets - only around 1 in 8 packets is getting through LoRaWAN looks great, but I don't want to pay a subscription.

You can give gcc the option -fno-gnu-unique to instruct the compiler to forget the GNU-specfic unique global symbol binding. Why was the identity of the Half-Blood Prince important to the story? If Dumbledore is the most powerful wizard (allegedly), why would he work at a glorified boarding school? But basically if I have setone function to specified memory section and try to call function withstring parameter.

It must either have or not have the GROUP attribute, but either way there is no conflict with a section custom of the same name in other_source.o having the opposite status. See http://www.avrfreaks.net/index.p... In the sed command we need *$$ as the eol-marker to escape make-expansion of $. -fno-gnu-unique is passed in the compiler flags to fill-out the clang mimicry.

But inline_get_data() has been made a weak, neither global nor local symbol (w) and inline_get_data()::inline_data, although it is syntactically block-scope static, has been made a unique global symbol (u). A section custom generated by gcc in source.o is a section in source.o. Log in or register to post comments Top saaadhu Level: Hangaround Joined: Sun.

That's why we can replace the section names custom.a and custom.b with custom, per original, and successfully compile. But basically if I have setone function to specified memory section and try to call function withstring parameter. What version of GNU ld? Not the answer you're looking for?

The first one the compiler gets to works (of course), as do all other with the same (zero or non-zero) values as the first. I have no control over the function signature,the *data variables are produced by a macro provided by me, and they can appear anywhere. I need to produce a macro, e.g: STORE(x), which can appear in any function body, stores the given x, and returns a handle. –erenon Feb 21 at 14:44 Thanks Jan 2, 2013 - 03:52 PM 12345Total votes: 0 The root cause of your problem is that at least one ordinary (const) object and one volatile const object are in the

If you insist on using library, you can at least let it use its own library and then the data can be in the normal places.
