Title: Metrowerks w/ configure HOWTO
|
||||
Author: David Elliott
|
||||
Id: $Id$
|
||||
|
||||
=== Introduction to Metrowerks command line tools ===
|
||||
|
||||
Since CodeWarrior version 8, Metrowerks has provided command-line compilers
|
||||
hosted on OS X. There are three available targets.
|
||||
|
||||
1) Mac OS X/PPC
|
||||
Compiler: mwcc
|
||||
Linker: mwld
|
||||
-- File formats --
|
||||
Executable: Mach-O
|
||||
Shared Library: Mach-O (bundle, dylib, etc.)
|
||||
Static Library: CodeWarrior
|
||||
Object: CodeWarrior
|
||||
|
||||
2) Mach-O/PPC
|
||||
Compiler: mwccppc
|
||||
Linker: mwldppc
|
||||
-- File formats --
|
||||
Executable: Mach-O
|
||||
Shared Library: Mach-O (bundle, dylib, etc.)
|
||||
Static Library: Archived (ar) Mach-O (.a files)
|
||||
Object: Mach-O .o files
|
||||
|
||||
3) Mac/PPC
|
||||
Compiler: mwpefcc
|
||||
Linker: mwpefld
|
||||
-- File formats --
|
||||
Executable: PEF
|
||||
Shared Library: PEF ("code fragments")
|
||||
Static Library: CodeWarrior
|
||||
Object: CodeWarrior
|
||||
|
||||
As you can see, only one of these targets produces Mach-O .o files that
|
||||
normal ar and ranlib could hope to handle. It's no matter though,
|
||||
really all that ar and ranlib do is create a static library (.a) from a
|
||||
collection of .o files. This can be emulated by a shell script which
|
||||
calls the appropriate mwld. I've provided one called mwar which does this.
|
||||
For ranlib simply use true since mwar does all of the work.
|
||||
|
||||
=== Metrowerks Environment Variables ===
|
||||
|
||||
In order for any of these programs to work some environment variables
|
||||
must be set. The compiler must know where to look for headers (CIncludes).
|
||||
The linker needs to know where to look for libraries (Libraries) such as
|
||||
those specified on the commandline with -l as well as crt1.o (or sometimes
|
||||
mwcrt1.o) for OS X. The linker also needs to know if any additional
|
||||
libraries should be linked into executables (LibraryFiles). Finally,
|
||||
on OS X the linker needs to know where to look for Frameworks (FrameworkPaths).
|
||||
These are controlled by the following environment variables:
|
||||
|
||||
1) Mac OS X/PPC
|
||||
CIncludes: MWCMacOSXPPCIncludes
|
||||
Libraries: MWMacOSXPPCLibraries
|
||||
LibraryFiles: MWMacOSXPPCLibraryFiles
|
||||
FrameworkPaths: MWFrameworkPaths
|
||||
|
||||
2) Mach-O/PPC
|
||||
CIncludes: MWCMachPPCIncludes
|
||||
Libraries: MWMachPPCLibraries
|
||||
LibraryFiles: MWMachPPCLibraryFiles
|
||||
FrameworkPaths: MWFrameworkPaths
|
||||
|
||||
3) Mac/PPC
|
||||
CIncludes: MWPEFCIncludes
|
||||
Libraries: MWPEFLibraries
|
||||
LibraryFiles: MWPEFLibraryFiles
|
||||
FrameworkPaths: (N/A)
|
||||
Notes (mwldppc 3.0.3 build 343):
|
||||
The environment variables (including MWPEFLibraries) aren't read until after
|
||||
the command line options have been parsed! The command line option parser
|
||||
actually tries to do the linking from within the parser and thus -l options
|
||||
which don't have a -L specifying where to look for the library do not work.
|
||||
Yes, this means that MWPEFLibraries is essentially useless AFAICT.
|
||||
|
||||
I have provided an example mwvars.sh. It's what I use with CW 8.3. YMMV.
|
||||
|
||||
=== Compiling wxWidgets targetting Mac OS X with Metrowerks ===
|
||||
|
||||
With recent wxWidgets (2.5.5) it is possible to compile using the
|
||||
Metrowerks tools with minimal effort. You may use either mwcc/mwld
|
||||
or mwccppc/mwldppc. Ideally you will have the tools on your path
|
||||
on your path as well as the mwar script I've provided. You will also
|
||||
have had to source mwvars.sh (either yourself or by sourcing it from
|
||||
your .profile or .bash_profile).
|
||||
|
||||
Before beginning I strongly recommend you write a simple C++ hello world
|
||||
program. I recommend #include <iostream> and cout << "Hello World" << endl;.
|
||||
This will ensure your C++ standard library is working. Note that
|
||||
you can compile this using mwcc hello.cpp. You will find a hello.cpp.o
|
||||
file as well as an a.out file if the compiler and linker were successful.
|
||||
Assuming your compiler can produce a.out you're ready to begin.
|
||||
|
||||
As per usual, I recommend building outside the source tree.
|
||||
From the source tree (workingDirectory$ is the prompt)
|
||||
|
||||
wxWidgets$ mkdir ../BUILD_MACd_CW8
|
||||
wxWidgets$ cd ../BUILD_MACd_CW8
|
||||
BUILD_MACd_CW8$ ../wxWidgets/configure --enable-debug --disable-shared CC=mwcc CXX=mwcc LD=mwld AR=mwar RANLIB=true
|
||||
[ configure hopefully succeeds ]
|
||||
BUILD_MACd_CW8$ make
|
||||
[ make hopefully succeeds ]
|
||||
BUILD_MACd_CW8$ make -C samples/minimal
|
||||
[ minimal make succeeds ]
|
||||
BUILD_MACd_CW8$ ./samples/minimal/minimal.app/Contents/MacOS/minimal
|
||||
[ minimal runs and your prompt will return when you Quit the app ]
|
||||
|
||||
The important options are CC=mwcc CXX=mwcc LD=mwld AR=mwar RANLIB=true
|
||||
Right now you also need --disable-shared. Eventually I hope to add the
|
||||
ability to created shared libraries.
|
||||
|
||||
If you wish to use the Mach-O compilers instead of the Mac OS X compilers
|
||||
then use CC=mwccppc CXX=mwccppc LD=mwldppc. You don't need a special
|
||||
AR or RANLIB with this compiler.
|
||||
|
||||
At the moment, precompiled headers aren't supported though you don't need
|
||||
to pass --disable-precomp-headers since the Makefiles know they can't do PCH.
|
||||
I hope to add this soon.
|
||||
|
||||
As you can see, this is not wildly different from compiling using any
|
||||
other compiler (for instance GCC). The same files that would be compiled
|
||||
by gcc are now compiled by mwcc. The same files that would be linked
|
||||
by the combination of ar and ranlib are now linked using the mwar shell
|
||||
script that calls mwld to do the work and using true in place of ranlib.
|
||||
The same files that would be linked using ld (i.e. the executable sample)
|
||||
are linked using mwld.
|
||||
|
||||
|
||||
=== Compiling wxWidgets targetting Mac OS (Carbon) with Metrowerks ===
|
||||
|
||||
Compiling for Mac OS PEF Carbon is not really more or less difficult
|
||||
than compiling for OS X. However, there is still some work left to do.
|
||||
|
||||
In particular, the -lCarbonLib and -lQuickTimeLib options to the linker don't
|
||||
work because of the aforementioned bug in mwpefld. To fix this you can add
|
||||
-L/path/to/Universal/Libraries/StubLibraries to LDFLAGS. Unfortunately
|
||||
because autoconf (2.59) doesn't always use eval appropriately you cannot
|
||||
have spaces in the path. What I recommend is to make a symlink from
|
||||
/Applications/Metrowerks CodeWarrior 8.0/Metrowerks CodeWarrior/MacOS Support to some path which can be accessed without using spaces.
|
||||
Something like this:
|
||||
~$ ln -snf "/Applications/Metrowerks CodeWarrior 8.0/Metrowerks CodeWarrior/MacOS Support" MW_MacOS
|
||||
|
||||
There is also a problem with the samples Makefiles. Currently they clear
|
||||
the resource fork of the executable rather than append to it. This
|
||||
can be remedied by adding the -a option to Rez before making in that
|
||||
sample's directory. I hope to fix this soon.
|
||||
|
||||
Assuming you work around these it's pretty straightforward:
|
||||
|
||||
wxWidgets$ mkdir ../BUILD_MACCARBONd_CW8
|
||||
wxWidgets$ cd ../BUILD_MACCARBONd_CW8
|
||||
BUILD_MACCARBONd_CW8$ ../wxWidgets/configure --host=powerpc-apple-macos --enable-debug --disable-shared CC=mwpefcc CXX=mwpefcc LD=mwpefld AR=mwpefar RANLIB=true LDFLAGS=-L/Users/yourname/MW_MacOS/Universal/Libraries/StubLibraries
|
||||
[ configure hopefully succeeds ]
|
||||
BUILD_MACd_CW8$ make
|
||||
[ make hopefully succeeds ]
|
||||
BUILD_MACd_CW8$ make -C samples/minimal
|
||||
[ minimal make succeeds ]
|
||||
BUILD_MACd_CW8$ /System/Library/Frameworks/Carbon.framework/Versions/A/Support/LaunchCFMApp ./samples/minimal/minimal
|
||||
[ minimal runs and your prompt will return when you Quit the app ]
|
||||
|
||||
Unlike the OS X case not many people compile wxMac Carbon PEF using configure.
|
||||
From time to time there may be minor problems. Please report these using
|
||||
the sourceforge bug tracker.
|
||||
|
||||
=== Other Metrowerks notes ===
|
||||
--- Object file extension ---
|
||||
By default, the mw compilers when used with the -c option will append .o
|
||||
to the source filename (following symlinks even). This is in contrast to
|
||||
normal compilers which replace the files extension with .o. To get the
|
||||
normal behavior you must add -ext o to the compiler options. The wxWidgets
|
||||
configure script does this and the macros to check for this are part of
|
||||
Bakefile (bakefile.sourceforge.net).
|
||||
|
||||
--- Static library extension ---
|
||||
The CodeWarrior IDE typically uses the .lib extension for CodeWarrior static
|
||||
libraries and .a for Mach-O static libraries (ar/ranlib archives). The
|
||||
wxWidgets makefiles always use .a. This isn't really a problem just be
|
||||
aware that the .a files aren't really ar/ranlib archives and aren't useable
|
||||
by anything other than CodeWarrior itself.
|
||||
|
||||
--- IDE ---
|
||||
As far as I know it should be possible to use libraries created by
|
||||
the command line tools from the IDE. For instance, you could compile
|
||||
wxWidgets using this method but continue to use the IDE for your application.
|
||||
Personally, I prefer sticking with the command line so I haven't tried this.
|
||||
|
||||
--- OS X SDKs ---
|
||||
Before CodeWarrior 9.3 the usage of SDKs (those in /Developer/SDKs) is
|
||||
impossible. You might think that it would work simply be prefacing any
|
||||
/System or /usr paths with the SDK path when setting the environment variables.
|
||||
Unfortunately, the libraries and frameworks inside these SDKs contain absolute
|
||||
paths to libraries and frameworks which they depend on. Thus, the linker
|
||||
attempts to load the non-SDK version to satisfy the dependency.
|
||||
|
||||
To ensure an app will work correctly on previous versions of the OS you
|
||||
can use Apple's availability macros.
|
||||
|
||||
--- CodeWarrior 8.3 and Panther ---
|
||||
CodeWarrior 8.3 has some problems running on Panther. When using the IDE
|
||||
version it is typical to change the OS X directory to the 10.2 SDK.
|
||||
Unfortunately, this is impossible with the command line compiler due to
|
||||
the aforementioned bug. Thus, the only solution is to allow CodeWarrior
|
||||
8.3 to work with Panther's headers. Fortunately, this isn't as hard
|
||||
as some people (particularly those at Metrowerks) would make you think.
|
||||
|
||||
First of all, there are issues with Apple's headers declaring conflicting
|
||||
types. Particularly with respect to wchar_t. Now, I'm sure you're
|
||||
aware of the "(wchar_t Support fix)" directory. What you need to do
|
||||
is create another one called "(wchar_t Support Panther fix)" using the
|
||||
provided machine/ansi.h file which contains some minor changes from
|
||||
the Metrowerks version.
|
||||
|
||||
Secondly, there is an issue with crt1.o. Apple's position is that
|
||||
/usr/lib/crt1.o is intended to be used only with Apple's GCC.
|
||||
Metrowerks does provide an mwcrt1.o and when you're using the IDE you
|
||||
can perfectly well use it instead of Apple's crt1.o. Unfortunately,
|
||||
when you are using mwld it has crt1.o hardcoded. Very fortunately, it
|
||||
has only the filename encoded and it searches the libraries path!
|
||||
What I do is symlink "Mac OS X Support/Libraries/Startup/mwcrt1.o" to
|
||||
crt1.o in the same directory.
|
||||
|
||||
--- MSL on OS X ---
|
||||
In mwvar.sh for the Mac OS X/PPC toolchain I've used MSL C++ with the
|
||||
BSD CRT. To do this I used the .a files. Earlier I used the .lib files
|
||||
but these also require the MSL C .lib. AFAIK using this would cause
|
||||
the MSL CRT to be used and I think I don't want that unless I'm using
|
||||
the MSL CRT headers. It did work although I never tested it with
|
||||
anything too complex. I suspect it would have failed although I'm
|
||||
wondering how it works with the CW projects because I think they do
|
||||
link with the MSL_C libs. This is probably very wrong.
|
||||
|
||||
If you do decide to use the MSL_C libs you'll need to add
|
||||
"MSL/MSL_C/MSL_MacOS/Src/console_OS_X.c". Unfortunately,
|
||||
mwld is a linker and doesn't understand C source code. Thus you must
|
||||
compile this file and use the compiled version.
|
||||
|
||||
What I did was simply run mwcc -c console_OS_X.c to generate a
|
||||
console_OS_X.c.o object file. This file must be in MWMacOSXPPCLibraryFiles.
