** (UN)FREQUENTLY ASKED QUESTIONS **
1. Why do you have to specify PREFIX= even when building
when overriding the default ?
2. When overriding the default prefix, how do you compile
and link my program ?
--
1. Why do you have to specify PREFIX= even when building,
when overriding the default ?
Because it allows easier linking. The way the Linux
link loader works, if the library name has a slash in it,
then it resolves it that way. If it doesn't it goes through
a series of steps which tries to find it. However, without
updating a certain file it won't find it under '/usr/local'
(and similar with '/tmp'). Therefore, as long as you have
the same PREFIX= (or don't specify it at all), all you need
to do to link to the shared version is link to it (and any
other dependencies; -lpthread comes to mind here). For
example the link options might be :
-langelscript_s -lpthread
--
2. When overriding the default prefix, how do you compile
and link my program ?
An example scenario is the following :
You installed into /opt which means the following
files should exist :
/opt/include/angelscript.h
/opt/lib/libangelscript.so (which is a symbolic link to
the current version installed)
/opt/lib/libangelscript.a (the static library).
If you #include angelscript.h you might normally
have :
#include <angelscript.h>
However, when that file is not in the standard directories
the compiler searches, you have to either use :
#include "/opt/include/angelscript.h"
(method one)
or alternatively keep the include (using the angle brackets)
but pass the include path (or paths actually but in this case
path) to the compiler so it knows to search an additional
location. If you're using g++ then the following option
will work (it also works for gcc but I am assuming you
are using C++) :
-I/opt/include
You must however still link. You therefore must pass another
option to the compiler (which will pass it to the linker)
and the option os -L which is used like so (to follow the
scenario) :
-L/opt/lib
The rest is the same.
CONTACT INFO:
If you have any questions or concerns, by all
means have Andreas contact me (at this time I
don't have an email I feel okay sharing - if it
seems this is of use to others I will likely
create an email on my server for this very
purpose). For now Andreas can forward the
message to me.

If you want to override /usr/local as the default prefix
(which means /usr/local/include would have the header file and
/usr/local/lib would have the library files), then run
make, make install and make uninstall (to build, to
install and uninstall respectively - you need it for
all three as I explain below) :
make PREFIX=/tmp
make PREFIX=/tmp install
make PREFIX=/tmp uninstall
The last two will of course have to be done
as root if you need permissions to write to
the directory (for /tmp you wouldn't unless
the files already existed by someone else and
you didn't have permission).
In any case, the above would install header file
under '/tmp/include' and the library file(s) under
'/tmp/lib'.
If you want to know the technical details as to why
you have to (when overriding the install location)
specify PREFIX= even when building, see the FAQ
file (summary: it makes it easier for you when linking
in the shared library).
A word of caution to those overriding prefix :
--
You are more than welcome to disregard this but I feel
it is something I should bring up. If you do override
the prefix I strongly recommend you do not specify
'/usr'. Why one might ask. The typical way is
that user-compiled programs/libraries/etc. go under
'/usr/local' (other times '/opt'). This has multiple
benefits: you keep '/usr' clean and if you have a
package manager then it makes it easy to say:
"The only files under /usr/include and /usr/lib are
those that belong to a package."
In other words it is easier to maintain integrity
and verify everything. Most important of it all
(aside the security implications) is this:
You have less chance of name clashes. If there ever
is a package that installs to /usr and it includes
the files (maybe a package for AngelScript) then you
will have issues.
--
Lastly: I don't have a way to test the phone builds
so I cannot verify the build process (it really
depends on the environment and architecture, like
most things); I'm an old-timer that hates the
"smart" trend (besides: it is a horrible misuse
of the world 'smart').
CONTACT:
If you have any questions or concerns, by all
means have Andreas contact me (at this time I
don't have an email I feel okay sharing - if it
seems this is of use to others I will likely
create an email on my server for this very
purpose). For now Andreas can forward the
message to me.

If you haven't done that already set up an environment variable named MINGDIR
pointing the the directory where your MinGW is, e.g. "C:\MINGW"
To compile the library, just type in the command line:
make
make install

// as_callfunc_arm.cpp
//
// These functions handle the actual calling of system functions on the arm platform
//
// Written by Fredrik Ehnbom in June 2009, based on as_callfunc_x86.cpp
//
// The code was complemented to support Linux with ARM by Carlos Luna in December, 2012.
//
// Added support for functor methods by Jordi Oliveras Rovira in April, 2014.
// This code has to conform to both AAPCS and the modified ABI for iOS
//

*
* A: The idea is to pre-arange the parameters so that X64_CallFunction() can do
* it's little magic which must work regardless of how the compiler decides to
* allocate registers. Basically:
* - the first MAX_CALL_INT_REGISTERS entries in tempBuff will
* contain the values/types of the x64INTARG parameters - that is the ones who
* go into the registers. If the function has less then MAX_CALL_INT_REGISTERS
* integer parameters then the last entries will be set to 0
* - the next MAX_CALL_SSE_REGISTERS entries will contain the float/double arguments
* that go into the floating point registers. If the function has less than
* MAX_CALL_SSE_REGISTERS floating point parameters then the last entries will
* be set to 0
* - index MAX_CALL_INT_REGISTERS + MAX_CALL_SSE_REGISTERS marks the start of the
* parameters which will get passed on the stack. These are added to the array
* in reverse order so that X64_CallFunction() can simply push them to the stack
* without the need to perform further tests

// as_callfunc_xenon.cpp
//
// These functions handle the actual calling of system functions
//
// This version is Xenon specific
// Modified from as_callfunc_ppc.cpp by Laszlo Perneky February 2007
//
// Modified by Cyril Tissier March 2010:
// various fixes in 'float' args passing / function return
// properly handling 'double' type
// various fixes in asm ppcFunc
// fix for variable arguments
//
// Modified by Anthony Clark May 2015
// Fixed the issue where int64 and uint64 could not be passed nativly
// few minor fixes within asm ppcFunc to handle int64 and uint64
// XBox 360 calling convention
// ===========================
// I've yet to find an official document with the ABI for XBox 360,
// but I'll describe what I've gathered from the code and tests
// performed by the AngelScript community.
//
// Arguments are passed in the following registers:
// r3 - r10 : integer/pointer arguments (each register is 64bit)
// fr1 - fr13 : float/double arguments (each register is 64bit)
//
// Arguments that don't fit in the registers will be pushed on the stack.
//
// When a float or double is passed as argument, its value will be placed
// in the next available float register, but it will also reserve general
// purpose register.
//
// Example: void foo(float a, int b). a will be passed in fr1 and b in r4.
//
// For each argument passed to a function an 8byte slot is reserved on the
// stack, so that the function can offload the value there if needed. The
// first slot is at r1+20, the next at r1+28, etc.
//
// If the function is a class method, the this pointer is passed as hidden
// first argument. If the function returns an object in memory, the address
// for that memory is passed as hidden first argument.
//
// Return value are placed in the following registers:
// r3 : integer/pointer values
// fr1 : float/double values
//
// Rules for registers
// r1 : stack pointer
// r14-r31 : nonvolatile, i.e. their values must be preserved
// fr14-fr31 : nonvolatile, i.e. their values must be preserved
// r0, r2, r13 : dedicated. I'm not sure what it means, but it is probably best not to use them
//
// The stack pointer must always be aligned at 8 bytes.
//

// ok - The script context must make sure to always allocate the local stack memory buffer on 16byte aligned boundaries (asCContext::ReserveStackSpace)
// ok - The engine must make sure to always allocate the memory for the script objects on 16byte aligned boundaries (asCScriptEngine::CallAlloc)
// ok - The application needs to inform a new flag when registering types that require 16byte alignment, e.g. asOBJ_APP_ALIGN16 (asCScriptEngine::RegisterObjectType)
// ok - The script object type must make sure to align member properties of these types correctly (asCObjectType::AddPropertyToClass)
// ok - Script global properties must allocate memory on 16byte boundaries if holding these types (asCGlobalProperty::AllocateMemory)
// TODO - The script compiler must make sure to allocate the local variables on 16byte boundaries (asCCompiler::AllocateVariable)
// TODO - The script compiler must add pad bytes on the stack for all function calls to guarantee that the stack position is 16byte aligned on entry in the called function (asCCompiler)
// TODO - The bytecode serializer must be capable of adjusting these pad bytes to guarantee platform independent saved bytecode. Remember that the registered type may not be 16byte aligned on all platforms (asCWriter & asCReader)
// TODO - The bytecode serializer must also be prepared to adjust the position of the local variables according to the need fro 16byte alignment (asCWriter & asCReader)
// TODO - The code for the native calling conventions must be adjusted for all platforms that should support 16byte aligned types (as_callfunc...)
// ok - When the context needs to grow the local stack memory it must copy the function arguments so that the stack entry position is 16byte aligned (asCContext::CallScriptFunction)
