Hello, I'm not on this list, please add me to Cc: in the follow up.
Do function pthread_getattr_np or pthread_attr_getstack work well on alpha? This is my question. Well, let me explain my issue. I am a maintainer of gauche package (a lisp interpreter which use bdwgc). Upgraded to bdwgc to 7.2d, gauche had FTBFS on alpha. See the log: http://buildd.debian-ports.org/status/fetch.php?pkg=gauche&arch=alpha&ver=0.9.3.3-4&stamp=1354011462 I think that the cause of this problem is the one of message (by bdwgc): GC Warning: pthread_getattr_np or pthread_attr_getstack failed for main thread It seems that pthread_getattr_np or pthread_attr_getstack failed on alpha. It only occurs on alpha, I don't see same/similar issue on any architectures. For gauche build, I added the following patch, so that another implementation (of LINUX_STACKBOTTOM) will be used to detect stack bottom (not using pthread_getattr_np and pthread_attr_getstack). Then, it builds successfully, now. --- a/gc/include/private/gcconfig.h +++ b/gc/include/private/gcconfig.h @@ -1724,6 +1724,7 @@ # endif # ifdef LINUX # define OS_TYPE "LINUX" +# define DONT_USE_GET_STACKBASE_FOR_MAIN # define LINUX_STACKBOTTOM # ifdef __ELF__ # define SEARCH_FOR_DATA_START --- a/gc/os_dep.c +++ b/gc/os_dep.c @@ -1158,7 +1158,7 @@ ptr_t result; /* also used as "dummy" to get the approx. sp value */ # if defined(LINUX) && !defined(NACL) \ && (defined(USE_GET_STACKBASE_FOR_MAIN) \ - || (defined(THREADS) && !defined(REDIRECT_MALLOC))) + || (defined(THREADS) && !defined(REDIRECT_MALLOC) && !defined(DONT_USE_GET_STACKBASE_FOR_MAIN))) pthread_attr_t attr; void *stackaddr; size_t size; -- -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
