None of this has been built on a Mac - there is none yet. It is the list a read-only audit of the
viewer/rugnux subtree produced, plus a serial -fsyntax-only pass of every reachable .cpp with
clang 16 + libc++ on Linux, which found exactly one error (the first item).
- JFJochDatasetInfoChartView: std::vector<fftwf_complex> does not compile with libc++, whose
construct_at refuses an array element type (float[2]). Use std::vector<std::complex<float>> and
the reinterpret_cast every other FFTW call site already uses.
- libcurl: GSSAPI off on Linux, and neither TLS nor GSSAPI on macOS. The viewer never sets
CURLOPT_HTTPAUTH, so Negotiate was dead weight that cost a krb5-devel build dependency; on macOS
curl's FindGSS refuses the system Heimdal outright, and with Secure Transport gone from curl
(8.15) TLS would mean a Homebrew OpenSSL - the only host library a Mac build would need.
Linux keeps OpenSSL. CURL_USE_GSSAPI is forced OFF rather than left unset so an existing build
tree drops its cached ON.
- libjpeg-turbo ExternalProject: CMAKE_SYSTEM_NAME/PROCESSOR were forwarded unconditionally, which
puts even a native sub-build into cross-compiling mode, and CMAKE_OSX_ARCHITECTURES / SYSROOT /
DEPLOYMENT_TARGET were not forwarded at all. Now the same rule the zlib-ng sub-build follows.
- ShadowAccumulatorGPU.cu was added on the JFJOCH_USE_CUDA option (default ON) instead of
JFJOCH_CUDA_AVAILABLE like every other .cu, so a machine without nvcc got a CUDA source in a
target with no CUDA language.
- CMAKE_OSX_DEPLOYMENT_TARGET defaults to 12.0 (overridable). Left unset, CMake takes the build
machine's OS version and the .dmg starts nowhere older.
- Standard headers that were only arriving transitively (<chrono>, <cmath>, <limits>, <cstring>,
<atomic>, <thread>, <string>); newer libc++ releases keep removing such transitive includes.
Checked: the seven changed sources pass clang 16 + libc++ -fsyntax-only. The CMake changes are
not configured or built.
