Exiv2

Exempi recently updated to xmpsdk 2014.12.

Is that the external project mentioned?

I'm not certain what exempi is. I think it might be a snap-shot of Adobe's public offering at some time in the past. Andreas has accepted the challenge of upgrading our XMP code to the latest public offering from Adobe. This is no trivial, there are changes which have to me made to Adobe's code to integrate correctly with Exiv2. #941

There was a recent discussion (on private email) with our friends at Alien Skin Software about using both libexiv2 and Adobe's XMPsdk in the same application. I believe that was successfully concluded with a little bit of namespace massage. I'll email Alien Skin to find out if they are happy.

Here's my latest email with them about using Adobe XMPsdk and Exiv2 in the same application. (2015-02-10)

There’s the issue:
677 rmills@rmillsmbp:~/gnu/exiv2/trunk $ find . -type f -exec grep -H sXMP_InitCount $___
./xmpsdk/src/XMPCore_Impl.cpp:XMP_Int32 sXMP_InitCount = 0;
./xmpsdk/src/XMPCore_Impl.hpp:extern XMP_Int32 sXMP_InitCount;
./xmpsdk/src/XMPCore_Impl.hpp:// ! Don't do the initialization check (sXMP_InitCount > 0) for the no-lock case. That macro is used
./xmpsdk/src/XMPCore_Impl.hpp:    XMP_Assert ( sXMP_InitCount > 0 );                        \
./xmpsdk/src/XMPMeta.cpp:    ++sXMP_InitCount;
./xmpsdk/src/XMPMeta.cpp:    if ( sXMP_InitCount > 1 ) return true;
./xmpsdk/src/XMPMeta.cpp:    --sXMP_InitCount;
./xmpsdk/src/XMPMeta.cpp:    if ( sXMP_InitCount > 0 ) return;
678 rmills@rmillsmbp:~/gnu/exiv2/trunk $ 

That variable sXMP_InitCount isn’t static.  It’s extern and that why it’s visible in xmpsdk.lib

Wrapping it (and his companions) in the Exiv2 namespace OR changing the name to sXMP_InitCount__ will almost certainly fix it.

I'm going to assign this (#742) to Andreas to be considered in the XMP upgrade project for v0.26.

I'm going to mark this as "Closed". It will be dealt with when we update XMPsdk in #941.
