https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265519 Bug ID: 265519 Summary: devel/libunwind: fix build with clang 15 Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: sunpoet@FreeBSD.org Reporter: dim@FreeBSD.org Flags: maintainer-feedback?(sunpoet@FreeBSD.org) Assignee: sunpoet@FreeBSD.org During an exp-run for llvm 15 (see bug 265425), it turned out that devel/libunwind fails to build with clang and lld 15, with multiple errors: setjmp/siglongjmp.c:111:48: error: incompatible pointer to integer conversion passing 'unw_word_t *' (aka 'unsigned long *') to parameter of t= ype 'unw_word_t' (aka 'unsigned long'); remove & [-Wint-conversion] if (unw_set_reg (&c, UNW_REG_EH + 2, &wp[JB_MASK]) < 0) ^~~~~~~~~~~~ ../include/libunwind-common.h:283:56: note: passing argument to paramet= er here extern int unw_set_reg (unw_cursor_t *, int, unw_word_t); ^ dwarf/Gparser.c:901:5: error: call to undeclared function '_Ux86_64_stash_frame'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] tdep_stash_frame (c, rs); ^ ../include/tdep-x86_64/libunwind_i.h:246:41: note: expanded from macro 'tdep_stash_frame' #define tdep_stash_frame UNW_OBJ(stash_frame) ^ The first error is because the syntax is indeed wrong, the '&' should be removed. The second error is because tdep_stash_frame() is only declared for Linux in libunwind_i.h, but it is used in Gparser.c. Declare it unconditionally to fix the problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
