1.1 Amazing Discovery 1 DumpFile is linked to libstdc++.6.dylib

------------------------------------------------------------------

|
||||
target/macintosh/intel_64/Release/DumpFile:

/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 22.0.0)

|
||||
|
||||
Conclusion: We should link -lXMPCore with libexiv2.26.dylib
|
||||
We should not link -lXMPCore with applications such as exiv2(.exe)
|
||||
We should build exiv2 code with visibility disabled "CXXFLAGS=-fvisibility=hidden -fvisibility-inlines-hidden"
|
||||
We must compile and link everything with "CXXFLAGS=-stdlib=libstdc++ -Wno-deprecated"

2 Puzzle with autotools/--with-adobe MacOS-X Only
|
||||
Added : 2017-08-17
|
||||
Modified: 2017-08-18
|
||||
|
||||
The --with-adobe code is new (added on Monday/Tuesday 2017-08-15).
|
||||
It's very much "Work in Progress" and will get lots more polishing.
|
||||
This builds and links on Mac and Linux (Cygwin isn't ready yet).
|
||||
Autotools isn't used with Visual Studio
|
||||
|
||||
Default build (which compile/links xmpsdk/src) is fine (and passes test suite)
|
||||
$ sudo make distclean ; make config ; ./configure ; make ; sudo make install ; make samples ; make tests
|
||||
|
||||
Status: The 2016/AdobeXMPsdk requires an entry point that's not in the C++ STL library
|
||||
./configure is building and passing the test suite
|
||||
./configure --with-adobe=2014 is broken on __ZNSs4_Rep11_S_terminalE
|
||||
./configure --with-adobe=2016 is broken on __ZNSiD0Ev
|
||||
|
||||
The missing entry points are in /usr/lib/libstdc++.6.dylib
|
||||
When I use install_name_tool to change to libstdc++.6.dylib, I crash in this:
|
||||
|
||||
$ c++filt __ZNSt3__112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEED1Ev
|
||||
std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >::~basic_string()
|
||||
$
|
||||
|
||||
There's something mixed up concerning the libraries used by Adobe's XMPSDK and libexiv2.26.dylib
|
||||
-stdlib=libstdc++ will link /usr/lib/libstdc++.6.dylib, however the compiler warns:
|
||||
clang: warning: libstdc++ is deprecated; move to libc++ [-Wdeprecated]
|
||||
|
||||
2.1 To build without the external Adobe SDK:
|
||||
--------------------------------------------
|
||||
|
||||
Edit config/config.mk.in and modify:
|
||||
XMPSDK_LIBS= -lXMPCore
|
||||
to
|
||||
XMPSDK_LIBS = ''
|
||||
|
||||
$ sudo make distclean ; make config ; ./configure --with-adobe ; make
|
||||
|
||||
The following command works:
|
||||
$ bin/exiv2 http://clanmills.com/Stonehenge.jpg is working
|
||||
|
||||
On 2017-08-15 The following command crashes when it attempts to execute XMPsdk code
|
||||

2.2 To add the external Adobe SDK to the mix:

This code is being accessed by Adobe XMPSDK 2016 libXMPCore.a and isn't in the c++ library.

|
||||

|

|
||||
|
||||
Adobe XMPSDK 2014 has a similar problem with __ZNSs4_Rep11_S_terminalE
|
||||
|
||||
$ nm -g Adobe/XMP-Toolkit-SDK-CC201412/libXMPCore.a | grep __ZNSs4_Rep11_S_terminalE | sort --unique

2.3 Notes (mostly to remind me of painful discoveries)
|
||||
------------------------------------------------------
|
||||
|
||||
How does the build get generated?
|
||||
$ make config
|
||||
This generates ./configure by reading config/configure.ac
|
||||
|
||||
When you use --with-adobe, CXXFLAGS and LDFLAGS are modified and ENABLE_XMP is set to 2016.
|
||||
Makefile has code to execute the script xmpsdk/buildXMPsdk.sh which
|
||||
downloads and builds the XMPsdk to create libCore.a (which we need) and libFiles.a
|
||||
|
||||
config/config.mk.in is converted into config/config.mk and included in xmpsdk/src/Makefile
|
||||
This is really ugly. config.mk also messes with CPPFLAGS and LDFLAGS
|
||||
|
||||
To get -lXMPCore into the mix, set XMPSDK_LIBS in config/config.mk.in
|
||||
XMPSDK_LIBS = -lXMPCore
|
||||
|
||||

3 Features to Add to the CMake code
|
||||
|
||||
* Auto usage of ccache on Linux and Mac.
|
||||
* Remove the trick to compile the documentation using the configure script. Native documentation generation on CMake.

4 Build design for v0.26.1
|
||||
|
||||
Added : 2017-08-18
|
||||
@ -408,77 +28,6 @@ Modified: 2017-08-23
|
||||
The purpose of the v0.26.1 is to release bug fixes and
|
||||
experimental new features which may become defaults with v0.27
|
||||
|
||||
4.1 Backwards compatibility
|
||||
This feature is being added to v0.26.1 DOT release and therefore existing
|
||||
behaviour of ./configure, CMake and msvc does not change.
|
||||
|
||||
./configure --enable-xmp (default is true) will build a library libxmpsdk.a
|
||||
using the code in xmpsdk/src. This library is linked into libexiv2.26.dylib
|
||||
|
||||
4.2 New Options for ./configure
|
||||
|
||||
./configure --with-std=c++11
|
||||
The default behaviour is the same as v0.26.0 --with-std=-std=c++98
|
||||
If the user requests --with-adobe, --with-std=c++11 is the default
|
||||
|
||||
./configure --with-adobe[=2016|2014]
|
||||
This causes the Adobe XMPsdk to be downloaded and built
|
||||
into the directory xmpsdk/Adobe/XMP-Toolkit-SDK-CC201607/libXMPCore.a
|
||||
|
||||
The dynamic library libexiv2.26.dylib will not have libXMPCore.a linked
|
||||
All applications (such as exiv2, exifprint etc) will require:
|
||||
-Lxmpsdk/Adobe/XMP-Toolkit-SDK-CC201607 -lXMPCore
|
||||
|
||||
This is an important architectural change in libexiv2.26.dylib
|
||||
However this is the way to achieve architecture independence between
|
||||
exiv2 and Adobe XMPsdk. A longer term goal is to totally remove
|
||||
all Adobe code from the exiv2 tarball.
|
||||
|
||||
Although --with-adobe causes the default compiler to be --with-std=c++11,
|
||||
the code will with --with-std=c++98 The Adobe XMPsdk is built using the script
|
||||
xmpsdk/buildXMPsdk which downloads and builds libXMPCore.a using Adobe provided
|
||||
CMake code. For the 2016 SDK, libXMPCore.a is built with -std=c++11
|
||||
|
||||
4.3 New Options for msvc
|
||||
This work has not been started. There are at least two possibilities:
|
||||
|
||||
1) To provide a new solution msvc/exiv2-adobe.sln
|
||||
This is the model used by msvc/exiv2-webready.sln
|
||||
2) To update msvc/configure.py to support options similar to
|
||||
./configure --with-std= and ./config --with-adobe
|
||||
|
||||
4.4 New Options for CMake
|
||||
Luis is adopting a two stage approach:
|
||||
|
||||
1) Cleaning up and refactoring the existing CMake scripts (*.cmake and CMakeLists.txt files)
|
||||
This work is proceeding well.
|
||||
2) Adding new EXIV2_ENABLE_XXXXs equivalent to ./configure --with-std and --with-adobe
|
||||
This work is waiting for Robin to complete the ./configure modifications.
|
||||
|
||||
It is expected that the CMake files will execute the script xmpsdk/buildXMPsdk.{sh|cmd}
|
||||
to perform the build of libXMPCore.a
|
||||
|
||||
4.5 New Options for contrib/cmake/msvc
|
||||
To be written. Luis' great new work may make this obsolete.
|
||||
|
||||
4.6 Scripts xmpsdk/buildXMPsdk.sh and xmpsdk/buildXMPsdk.cmd
|
||||
|
||||
These scripts download and build the Adobe XMPsdk. Minor modification of the SDK
|
||||
is necessary to enable the code to build. For example, Adobe does not support Cygwin
|
||||
and minor change are necessary to build on that platform.
|
||||
|
||||
Changes to Adobe code will be minimal and documented in xmpsdk/buildXMPsdk.{sh|cmd}
|
||||
|
||||
4.7 Support for 32/64 bit builds, Release/Debug, Shared/Static
|
||||
|
||||
1) v0.26.1 will build exactly as v0.26 and support linking static libxmpsdk.a
|
||||
32/64 static/shared debug/release are supported on all platforms
|
||||
|
||||
2) The new features (--with-std and --with-adobe) will only be supported for
|
||||
a static/release build of libXMPCore.a
|
||||
msvc will continue to supports 32/64 ReleaseDLL/Release/DebugDLL/Debug of libexiv2
|
||||
which will include the static libXMPCore.a or libxmpsdk.a
|
||||
|
||||
4.8 Support for MinGW
|
||||
MinGW msys/1.0 was deprecated when v0.26 was released.
|
||||
No support for MinGW msys/1.0 will be provided.
|
||||
@ -487,66 +36,6 @@ Modified: 2017-08-23
|
||||
|
||||
MinGW msys/2.0 might be supported as "experimental" in Exiv2 v0.26.2
|
||||
|
||||
4.9 Building and linking XMPsdk with libexiv2
|
||||
|
||||
Exiv2 v0.26 (and many earlier editions) contain Adobe XMPsdk code.
|
||||
The precise version of this code is unknown.
|
||||
The xmpsdk/ directory has files in src/*.cpp and include/*.hpp
|
||||
The xmpsdk/ has its own Makefile, CMakeLists.txt and msvc/xmpsdk/project files.
|
||||
|
||||
Exiv2 v0.26 builds a static library libxmpsdk.a which is linked into libexiv2.a
|
||||
|
||||
None of this will change in Exiv2 v0.26.1
|
||||
|
||||
Exiv2 v0.26.1 will support a new option to download and build "pure Adobe" XMPsdk.
|
||||
Three flavours will be supported:
|
||||
2013 http://download.macromedia.com/pub/developer/xmp/sdk/XMP-Toolkit-SDK-CC-201306.zip
|
||||
2014 http://download.macromedia.com/pub/developer/xmp/sdk/XMP-Toolkit-SDK-CC201412.zip
|
||||
2016 http://download.macromedia.com/pub/developer/xmp/sdk/XMP-Toolkit-SDK-CC201607.zip
|
||||
As Adobe appear to release new editions every 18 months, I guess that Adobe will release
|
||||
a new version in Spring 2018.
|
||||
|
||||
The autotools build supports new ./configure options:
|
||||
--with-adobe builds and links 4089256 Aug 23 11:19 ./xmpsdk/Adobe/XMP-Toolkit-SDK-CC201306/libXMPCore.a
|
||||
--with-adobe=2016 as --with-adobe
|
||||
--with-adobe=2014 4108792 Aug 23 11:18 ./xmpsdk/Adobe/XMP-Toolkit-SDK-CC201412/libXMPCore.a
|
||||
--with-adobe=2013 22242448 Aug 23 10:25 ./xmpsdk/Adobe/XMP-Toolkit-SDK-CC201607/libXMPCore.a
|
||||
|
||||
The build of the Adobe XMPsdk is "pure Adobe". We download the code and build it without modification.
|
||||
|
||||
The scripts to download and build the Adobe code is:
|
||||
xmpsdk/buildXMPsdk.sh
|
||||
xmpsdk/buildXMPsdk.cmd
|
||||
|
||||
Adobe build the 2016 SDK with -std=c++11. This links successfully with the libexiv2 -std=c++98 build.
|
||||
I haven't investigated which compiler Adobe use to build the 2013 and 2014 editions.
|
||||
|
||||
Mac Build
|
||||
Following the analysis of Adobe's build (Topics 1 and 2 in this report), it has been realised that:
|
||||
1 Adobe build the SDK with (both linker and compiler) -stdlib=libstdc++
|
||||
2 Visibility should be disabled in the compiler
|
||||
|
||||
CPPFLAGS = -I/usr/local/include -I/usr/local/include -std=c++98 -fvisibility=hidden -fvisibility-inlines-hidden \
|
||||
-stdlib=libstdc++ -Wno-deprecated -Ixmpsdk/Adobe/XMP-Toolkit-SDK-CC201607/public/include
|
||||
LDFLAGS = -L/usr/local/lib -lpthread -stdlib=libstdc++ -Wno-deprecated -Lxmpsdk/Adobe/XMP-Toolkit-SDK-CC201607
|
||||
LIBS = -lz -lXMPCore
|
||||
CXX = g++
|
||||
|
||||
Linux Build
|
||||
CPPFLAGS = -I/usr/local/include -std=c++98 -Ixmpsdk/Adobe/XMP-Toolkit-SDK-CC201607/public/include
|
||||
LDFLAGS = -L/usr/local/lib -ldl -lpthread -Lxmpsdk/Adobe/XMP-Toolkit-SDK-CC201607
|
||||
LIBS = -lz -lm -lXMPCore
|
||||
CXX = g++
|
||||
|
||||
When 2013 or 2014 are selected, the appropriate -Ipath and -Lpath should be set.
|
||||
|
||||
CMake Build
|
||||
A new option -DEXIV2_ENABLE_ADOBE[=2016|=2014|=2013] should be added.
|
||||
The build of XMPsdk should be performed with xmpsdk/buildXMPsdk.sh (or xmpsdk/buildXMPsdk.cmd for Visual Studio)
|
||||
The build should set same LDFLAGS and CPPFLAGS as the autotools build.
|
||||
|
||||
When the options -DEXIV2_ENABLE_ADOBE is not used, we should compile the code in xmpsdk/src
|
||||
to create and link libxmpsdk.a
