…tern". This commit updates explicit instantiation to use "extern" keyword similarly to what was done in InsightSoftwareConsortium/ITK@b72726c (BUG: Explicitly instantiate common MetaDataObjects). By using the recommended approach for template instantiation, this commit should also fix TransformReadWriteTest where TransformIO failed to be successfully instantiated. Here is the error that was reported when the was compiled on MacOSX using clang-6.0: libc++abi.dylib: terminating with uncaught exception of type itk::ExceptionObject: /scratch/dashboards/MacOSX-clang6/ITK/Modules/IO/TransformBase/src/itkTransformFileWriterSpecializations.cxx:212: itk::ERROR: TransformFileWriterTemplate(0x7fa552100f10): The input of writer should be whether a double precision or a single precision transform type. Called from TransformFileWriterTemplate<double,double$ It also updates IOTransformDCMTK remote module to include a similar fix. Note #1: To shut up the following warning from gcc, context specific "pragma GCC diagnostic" preprocessor instructions have been added: warning: type attributes ignored after type is already defined [-Wattributes] This is most likely specific to gcc (see issue #39159), and at the time of this commit there were no resolution or information about gcc version where the "problem" is addressed. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=39159 For that reason, the "pragma GCC diagnostic" is applied in-conditionally of the gcc version being used. Note #2: While "extern" is only part of the c++ standard starting with c++11 (see section 14.7.2 of the standard), it is supported by Visual Studio 2008, GCC and Clang using compiler specific extension in earlier version: * Visual Studio 2008: https://msdn.microsoft.com/en-us/library/by56e477(v=vs.90).aspx * Gcc: https://gcc.gnu.org/onlinedocs/gcc-4.8.4/gcc/Template-Instantiation.html#Template-Instantiation * Clang (since v2.9): http://clang.llvm.org/cxx_status.html For completeness, initial draft of the "extern" keyword were first introduced in 2003 [1] and then revised in 2006 [2], and ultimately standardized in c++11 [3]: [1] N1448: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2003/n1448.pdf [2] N1987: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1987.htm [3] N3242: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/ See InsightSoftwareConsortium#3393 Suggested-by: Bradley Lowekamp <[email protected]> Co-authored-by: Bradley Lowekamp <[email protected]> Change-Id: I2e3ca2843c500b9bb60bbffc5f3629bc5be0a6fd

In 03c8176 a concept check was added that the sobel operator uses a signed pixel type. On Linux aarch64, ❯ c++ --version c++ (Debian 12.2.0-14) 12.2.0 ❯ uname -a Linux deb 6.1.0-18-arm64 #1 SMP Debian 6.1.76-1 (2024-02-01) aarch64 GNU/Linux char is unsigned, which causes the concept check to fail. Switch `char` to `signed char`.

Found with thread sanitizer (TSan) running the `itkANTSNeighborhoodCorrelationImageToImageRegistrationTest` unit test.
There was already a `m_ANTSAssociateOnceFlag` flag for use with `std::call_once`, so I just used that in this place too (it's already used elsewhere).
Partial backtrace from TSan:
```
