Robg: "type info" is undefined moved to "typeinfo" is undefined

If you are compiling with s2scompile (the STRIDE compiler) and encounter the following error message:

error: identifier "type_info" is undefined

You should add the following include statement to the file being compiled:

#include <typeinfo>

This will resolve the problem. Note: This issue is known to occur when compiling using the STRIDE compiler using some versions of the Microsoft standard library include files.

Error compiling standard libaries

Robg:

Because the STRIDE C/C++ compiler (s2scompile) is a program analysis
and instrumentation tool, it does not include its own copy of the
standard C and C++ library header files. Rather, the recommended use
is to configure the STRIDE compiler to use the same header files
as the target compilation system. Normally this works fine without
adjustment. However, from time to time the target compiler may have
certain macros specially predefined that require adjustment
within STRIDE.

If you encounter syntax errors when compiling the systems standard
library header files, the issue is typically that one or more macros
is built into the target compiler and the STRIDE environment needs to
be adjusted to also include the macro. Typically this requires the user
to put one or more defines (-D options) on the STRIDE compiler
commandline.

As an example, in one case, compilation of the local stdlib.h file
yielded the following error message:

"C:/Apps/QDSP6/release_1.0.00/tools/dinkumware/include/common/stdlib.h", line
161: error: linkage specification is incompatible with previous "atexit"
(declared at line 151)

Examination of the stdlib.h file and included filed contents revealed that the
following macro definition needed to be added to the STRIDE compile commandline.

-D_HAS_STRICT_LINKAGE=0

= The scl_struct_sized pragma =

The scl_struct_sized pragma is used to identify a sized structure. A sized structure is a C programming pattern representing structure whose size is variable and defined by one of the members of the structure. In other words the actual size of the structure is defined by programmer convention. This pragma is infrequently used, but must be used, whenever the programmer defined size does not match the C language size (as calculated by the sizeof macro) of the structure.

| Struct, Pointer
| Specifies a structure type (or a pointer to such type) that is to be sized (allocated bytes beyond its type definition).
The following restrictions apply:
* The structure type may not be pointed to by a sized pointer.
* The structure type may not be a member of any other structure or union.
* The structure type may not be passed as a function parameter.
* The structure type may only reside in IN/INOUT memory blocks.
* If the last member of the structure is an array, the array's size is calculated based upon max-size - (size of struct's other members).
* If the last member of the structure is an array, the array's element type may not contain a sized structure or a conformant array (see [[scl_conform]]).

|-
| ''max-size''
| Integer
| Specifies the number of bytes to be allocated for the sized struct.
The following restrictions apply:
* The max-size type must be an integral type (int, short, char).
* The max-size value (at runtime) may not be less than the structure's type size.
* The max-size value (at runtime) may not exceed the maximum payload size.
* The max_size field must be in the same payload block as the type-name sized struct (i.e. no indirection '*' or '->').
