ARMCC: source input file "absacc.h" not found

Information in this knowledgebase article applies to:

  • MDK-ARM V5.11 and newer


Compiling a source file which includes "absacc.h" fails to compile with the following error message:

  error: #5: cannot open source input file "absacc.h": No such file or directory include


"absacc.h" was removed from \ARM\ARMCC\include since it is not part of the ARM Compiler 5 distribution.


"absacc.h" defines __at(addr) for __attribute__((at(addr))) as shown below

#define __at(_addr) __attribute__ ((at(_addr)))

This was used as shortcut and for compatibility reasons.

Download the attached file and place it into your project or system include path.
