Compilation errors when structs with same name exist in different modules

[stephaneberle9]

This is caused by the fact that struct names (in contrast to union names, e.g.) don't get prefixed with the name of their modules.

E.g., I have a struct

exported struct MyData { ... };

in a module named "MyModule".

Expected generated code in "MyModule.h":

struct MyModule_MyData { ... };

Actual generated code in "MyModule.h":

struct MyData { ... };

works for me. seems to be not valid anylonger. Please reopen with an

Steps to reproduce:

• Go to com.itemis.smartmeter.ssec.implementation.impl.application.ApplicationFlashMemory and remove "Application" prefix in ApplicationInformationMemory struct.
• Do the same thing with com.itemis.smartmeter.ssec.implementation.impl.metrology.MetrologyFlashMemory, so that the struct name is just "InformationMemory" in both cases.
• Rebuild and compile com.itemis.smartmeter.ssec.tests.integration.calibration

You should then get the following compilation error:

In file included from MetrologyNodeStack.h:11:0, from CalibrationTest.h:13, from CalibrationTest.c:1: MetrologyFlashMemory.h:37:16: error: redefinition of 'struct S_InformationMemory' typedef struct S_InformationMemory { ^ In file included from ApplicationNodeStack.h:13:0, from CalibrationTest.h:11, from CalibrationTest.c:1: ApplicationFlashMemory.h:41:16: note: originally defined here typedef struct S_InformationMemory { ^ In file included from MetrologyNodeStack.h:11:0, from CalibrationTest.h:13, from CalibrationTest.c:1: MetrologyFlashMemory.h:39:3: error: conflicting types for 'InformationMemory' } InformationMemory; ^ In file included from ApplicationNodeStack.h:13:0, from CalibrationTest.h:11, from CalibrationTest.c:1: ApplicationFlashMemory.h:43:3: note: previous declaration of 'InformationMemory' was here } InformationMemory; ^

This problem is related to the fact that these structs had the prevent name mangling flag set to true, but the editor for the struct declaration didn't display that. This has been changed now, and I have also removed the flags from the mentioned structs.
