Build nodejs version 26.8.2 with clang\n2. Observe failure\n\n### How often does it reproduce? Is there a required condition?\n\nAlways while building with clang\n\n### What is the expected behavior? Why is that the expected behavior?\n\nSuccessful build with clang\n\n### What do you see instead?\n\nBuild failure while building with Clang\n\nA snippet from the build log:\n\n```\n...\nIn file included from ../../deps/LIEF/src/platforms/android/version.cpp:17:\nIn file included from ../../deps/LIEF/src/frozen.hpp:22:\n../../deps/LIEF/third-party/frozen/include/frozen/map.h:40:20: error: implicit instantiation of undefined template 'std::less\u003cLIEF::Android::ANDROID_VERSIONS>'\n   40 |   Comparator const comparator_;\n      |                    ^\n../../deps/LIEF/third-party/frozen/include/frozen/map.h:75:29: note: in instantiation of template class 'frozen::impl::CompareKey\u003cstd::less\u003cLIEF::Android::ANDROID_VERSIONS>>' requested here\n   75 |   impl::CompareKey\u003cCompare> less_than_;\n      |                             ^\n../../deps/LIEF/src/platforms/android/version.cpp:22:47: note: in instantiation of template class 'frozen::map\u003cLIEF::Android::ANDROID_VERSIONS, const char *, 8>' requested here\n   22 |   CONST_MAP(ANDROID_VERSIONS, const char*, 8) version2code {\n      |                                               ^\n/usr/include/c++/v1/__fwd/functional.h:25:8: note: template is declared here\n   25 | struct less;\n      |        ^\nIn file included from ../../deps/LIEF/src/platforms/android/version.cpp:17:\nIn file included from ../../deps/LIEF/src/frozen.hpp:22:\n../../deps/LIEF/third-party/frozen/include/frozen/map.h:110:20: error: implicit instantiation of undefined template 'std::less\u003cLIEF::Android::ANDROID_VERSIONS>'\n  110 |       : map{items, Compare{}} {}\n      |                    ^\n../../deps/LIEF/src/platforms/android/version.cpp:22:47: note: in instantiation of member function 'frozen::map\u003cLIEF::Android::ANDROID_VERSIONS, const char *, 8>::map' requested here\n   22 |   CONST_MAP(ANDROID_VERSIONS, const char*, 8) version2code {\n      |                                               ^\n/usr/include/c++/v1/__fwd/functional.h:25:8: note: template is declared here\n   25 | struct less;\n      |        ^\n../../deps/LIEF/src/platforms/android/version.cpp:22:47: error: constexpr variable 'version2code' must be initialized by a constant expression\n   22 |   CONST_MAP(ANDROID_VERSIONS, const char*, 8) version2code {\n...\n```\n\n### Additional information\n\nI think this is due to stricter include requirements on clang\nI was able to build by adding `#include \u003cfunctional>` in deps/LIEF/third-party/frozen/include/frozen/map.h","author":{"url":"https://github.com/listout","@type":"Person","name":"listout"},"datePublished":"2026-09-17T03:34:16Z","url":"https://github.com/nodejs/node/issues/66076"}
