How to build DCMTK 3.6.1 libs for iOS? - ios

Question

I followed Russes' instructions found at http://forum.dcmtk.org/viewtopic.php?f=3&t=3047&start=15
With a fresh copy of his "afab" git branch, I built Xcode project for x86 arch with the command line:
cmake -DIOS_PLATFORM=SIMULATOR64 -G Xcode ../dcmtk.public
or for arm arch with:
cmake -DIOS_PLATFORM=OS -G Xcode ../dcmtk.public
However, my Xcode project can't be successfully built because of, at least, the following errors:
List of Xcode errors on ofchrenc.cc file (for eg. "No class named Implementation in OFCharacterEncoding")
The compilation with Unix makefiles gives the same errors in my case:

I don't understand what is wrong in my configuration:
MacOs Sierra 10.12.2
Xcode 8.2
CMake 3.7.1 (I have the same issue previously with 3.5.2 version)
GNU Make 3.81 (for Unix makefiles compilation)
Apple LLVM version 8.0.0.8000042
Darwin version of host: 16.3.0
Building for minimum iOS version: 10.2 (SDK version: 10.2)

Answer 1

I'm not sure about the first error message but
/usr/local/include/dcmtk/ofstd/ofchrenc.h:97:21: note: member
declaration does not match because it is const qualified const
OFString &getLocaleEncoding() const;
seems to indicate that you are mixing an old version of "ofchrenc.h" (stored in "/usr/local/...") with a more recent version of "ofchrenc.cc" (stored in your working directory).
