Added matrix constructors + that do not initialize the matrix (this is faster in cases where + the initial value of the matrix is immediately overwritten anyway). + (Nick Porcino) + * Rewrote function closestPointOnBox(point,box). Shortened + the code, improved numerical accuracy, fixed a bug where + closestPointOnBox(box.center(),box) would return the center + of the +Z side of the box, even if the +/-X or +/-Y sides + were

By default, IlmBase will be built +for the system doing the building. For example, if you build IlmBase on +an Intel system, the libraries will be built for Intel. + +You can specify building for a different architecture, or multiple architectures, +by passing the "--enable-osx-arch" flag to configure. Building for multiple +architectures requires that "--disable-dependency-tracking" be passed as well. + +For example, to build for Intel and PowerPC: + +./configure --enable-osx-arch="i386 ppc" --disable-dependency-tracking. + +To build "4-way universal" for 32-bit and 64-bit Intel and PowerPC: + +./configure --enable-osx-arch="i386 ppc x86_64 ppc64" --disable-dependency-tracking. + +For more information on universal builds, see: + +http://developer.apple.com/documentation/Porting/Conceptual/PortingUNIX/compiling/chapter_4_section_3.html + +Earlier releases of IlmBase included an "--enable-osx-universal-binaries" +switch, which specifies a two-way universal build: Intel and PowerPC, 32-bit only. +This is still available, but deprecated in favor of the more flexible +"--enable-osx-arch" and "--enable-osx-sdk" switches. + + +Choosing an SDK on Mac OS X +------------------ +OS X allows you to specify one of several SDKs, or sysroots. This allows you to +target systems other than the system that your build machine runs. + +For example, if you are building on Mac OS X 10.4, but you need access to features +that were introduced in Mac OS X 10.5, you can build against the Mac OS X 10.5 +versions of system libraries and headers. + +You can choose to build IlmBase with a specific SDK using the "--enable-osx-sdk" +switch. For example: + +./configure --enable-osx-sdk=MacOSX10.5.sdk + +If you are building on Mac OS X 10.4 and want to build universal, you will need to +specify the universal version of the 10.4 SDK: MacOSX10.4u.sdk. Otherwise, you probably +don't need to specify an SDK. + +For more information on sysroots, see: + +http://developer.apple.com/documentation/DeveloperTools/gcc-4.2.1/gcc/Directory-Options.html + + +Shared libraries +---------------- + +IlmBase requires the "flat namespace" option when built as a shared +library. You may have problems trying to use IlmBase shared libraries +with applications that expect OS X's two-level namespace. We have not +tested the shared libs extensively, though they appear to work with +exrdisplay and exrheader, but use them at your own risk. We will +support two-level namespace shared libs in a future release. diff --git a/README.cmake.txt b/README.cmake.txt new file mode 100644 index 0000000..011648b --- /dev/null +++ b/README.cmake.txt @@ -0,0 +1,65 @@ +WINDOWS +------- + +Build IlmBase and OpenEXR on Windows using cmake +------------------ + +What follows are instructions for generating Visual Studio solution +files and building those two packages + +1.

Without an argument (see below) the library +will be built with a suffix made up of the major and minor versions. +For example, for version 2.0.0, the internal library namespaces will be +Imath_2_0, Iex_2_0, IlmThread_2_0 etc + +For additional flexibility and control, this option can take an additional +argument in which case the internal library namespace will be suffixed +accordingly. +For example: + ./configure --enable-namespaceversioning=ILM +will result in the namespaces of the type Imath_ILM, Iex_ILM etc. + +This can be useful for completely isolating your local build. + +Code using the library should continue to use the namespace Imath, or for +greater portability IMATH_NAMESPACE, to refer to objects in libImath. +In particular, the explicit use of the internal namespace is discouraged. +This ensures that code will continue to compile with customised or future +versions of the library, which may have a different internal namespace. + +Similarily, for other namespaces in the libraries: Iex, IlmThread and IlmImf. + +Note that this scheme allows existing code to compile without modifications, +since the 'old' namespaces Imath, Iex, IlmThread and IlmImf continue to be +available, albeit in a slightly different form. +This is achieved via the following, in the Imath case: + namespace IMATH_INTERNAL_NAMESPACE {} + namespace IMATH_NAMESPACE + { + using namespace IMATH_INTERNAL_NAMESPACE; + } +This is included in all header files in the Imath library and similar ones +are present for the libraries Iex, IlmThread and IlmImf. + +The only exception to this is where user code has forward declarations of +objects in the Imf namespace, as these will forward declare symbols in an +incorrect namespace +These forward declarations should be removed, and replaced with + #include , +which forward-declares all types correctly. + + + +-- Public/User Library Namespace +The option, --enable-customusernamespace, can override the namespace into +which we will 'export' the internal namespace. This takes an argument +that sets the name of the custom user namespace. +In the example above, IMATH_NAMESPACE could be resolved into something other +than Imath, say Imath_MySpecialNamespace. + +In nearly all cases, this will not be used as per the above discussion +regarding code compatibility. +Its presence is to provide a mechanism for not prohibiting the case when +the application must pass objects from two different versions of the library. diff --git a/README.win32 b/README.win32 new file mode 100644 index 0000000..e69de29 --- /dev/null +++ b/README.win32 diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 0000000..16b5f06 --- /dev/null +++ b/aclocal.m4 @@ -0,0 +1,8941 @@ +# generated automatically by aclocal 1.11.1 -*- Autoconf -*- + +# Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, +# 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc. +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, +[m4_warning([this file was generated for autoconf 2.63. +You have another version of autoconf.

(The user can also force certain +dnl compiler flags/libs to be tested by setting these environment +dnl variables.) +dnl +dnl Also sets PTHREAD_CC to any special C compiler that is needed for +dnl multi-threaded programs (defaults to the value of CC otherwise). +dnl (This is necessary on AIX to use the special cc_r compiler alias.) +dnl +dnl NOTE: You are assumed to not only compile your program with these +dnl flags, but also link it with them as well. e.g. you should link +dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS +dnl $LIBS +dnl +dnl If you are only building threads programs, you may wish to use +dnl these variables in your default LIBS, CFLAGS, and CC: +dnl +dnl LIBS="$PTHREAD_LIBS $LIBS" +dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +dnl CC="$PTHREAD_CC" +dnl +dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute +dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to +dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +dnl +dnl ACTION-IF-FOUND is a list of shell commands to run if a threads +dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to +dnl run it if it is not found.
