This failure means the size of `st_index_t` doesn't equal the size of `void*`, so this check was not redundant actually. ---------------------------------------- Misc #16025: 'st_check_for_sizeof_st_index_t' declared as array with a negative size (emscripten) https://bugs.ruby-lang.org/issues/16025#change-80276 * Author: vadimp (Vadim Peretokin) * Status: Assigned * Priority: Normal * Assignee: nobu (Nobuyoshi Nakada) ---------------------------------------- Compilation of st.h with Emscripten 1.38.30 fails: ``` c st.h:65:45: error: 'st_check_for_sizeof_st_index_t' declared as an array with a negative size typedef char st_check_for_sizeof_st_index_t[SIZEOF_VOIDP == (int)sizeof(st_index_t) ? 1 : -1]; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3rdparty/edbee-lib/vendor/onig/config.h:109:22: note: expanded from macro 'SIZEOF_VOIDP' #define SIZEOF_VOIDP 8 ^ 1 error generated. shared:ERROR: compiler frontend failed to generate LLVM bitcode, halting Makefile:36871: recipe for target 'regcomp.o' failed ``` Both sizeof are set to 8: ```c onig$ cat config.h | grep SIZEOF_LONG #define SIZEOF_LONG 8 #define SIZEOF_LONG_LONG 8 ``` Is there a way to fix this issue or add a workaround for emscripten (`__EMSCRIPTEN__`)? -- https://bugs.ruby-lang.org/ Unsubscribe:
