Summary [libpas] Build fails with libc implementations that lack execinfo.h
Adrian Perez
Reported 2025-10-14 07:39:56 PDT
For example, attempting to build with Musl: Source/bmalloc/libpas/src/libpas/pas_probabilistic_guard_malloc_allocator.c:52:10: fatal error: execinfo.h: No such file or directory 52 | #include <execinfo.h> | ^~~~~~~~~~~~ compilation terminated. Also, uCLibc supports being configured without support for backtrace()/execinfo.h, as per bug #102946 The right thing to do would be to check whether the backtrace() function and execinfo.h header are available. For example Source/WTF/wtf/StackTrace.h does exactly that: checks for HAVE(BACKTRACE) || HAVE(BACKTRACE_SYMBOLS), which is defined in Source/WTF/wtf/PlatformHave.h -- libpas should have similar checks.
