R11 configuration problem

Rate this Message:
Hello,
I tried to install R11R-5 on my new Imac running Snow Leopard and got this trying to configure: ... checking for IP version 6 support... yes checking for multicast support... rm: conftest.dSYM: is a directory yes checking how to correct for time adjustments... none checking if gethrvtime works and how to use it... not working checking if clock_gettime can be used to get process CPU time... not working checking for unreliable floating point execptions... and there it gets stuck, hangs forever (or a very long time). Anyone out there know what the problem is? No problems with R12, R13, and yes I need R11 as we have customer installations using R11 that we need to maintain.

There are two main changes related to that test between R11B-5 and R12B-5, the first is surrounding logic to only run the test if HiPE is enabled or the user requested the feature, the second is a check in the test itself against infinite SIGFPE loops. I suspect the latter is what's happening to you. The patch below backports that one fix to R11B-5, apply it and try ./configure again. --- otp_src_R11B-5/erts/configure.in.~1~ 2007-06-11 14:53:45.000000000 +0200 +++ otp_src_R11B-5/erts/configure.in 2009-11-03 18:41:17.000000000 +0100 @@ -1674,6 +1674,19 @@ AC_TRY_RUN([ volatile int erl_fp_exception; +/* + * We expect a single SIGFPE in this test program. + * Getting many more indicates an inadequate SIGFPE handler, + * e.g. using the generic handler on x86. + */ +static void new_fp_exception(void) +{ + if (++erl_fp_exception > 50) { + fprintf(stderr, "SIGFPE loop detected, bailing out\n"); + exit(1); + } +} + /* Is there no standard identifier for Darwin/MacOSX ? */ #if defined(__APPLE__) && defined(__MACH__) && !defined(__DARWIN__) #define __DARWIN__ 1 @@ -2017,7 +2030,7 @@ static void fpe_sig_action(int sig, sigi fpstate->mxcsr = 0x1F80; fpstate->sw &= ~0xFF; #endif - erl_fp_exception = 1; + new_fp_exception(); } static void do_init(void) @@ -2034,7 +2047,7 @@ static void do_init(void) static void fpe_sig_handler(int sig) { - erl_fp_exception = 1; + new_fp_exception(); } static void do_init(void) --- otp_src_R11B-5/erts/configure.~1~ 2007-06-11 19:16:18.000000000 +0200 +++ otp_src_R11B-5/erts/configure 2009-11-03 18:42:20.000000000 +0100 @@ -18197,6 +18197,19 @@ cat >>conftest.$ac_ext <<_ACEOF volatile int erl_fp_exception; +/* + * We expect a single SIGFPE in this test program. + * Getting many more indicates an inadequate SIGFPE handler, + * e.g. using the generic handler on x86. + */ +static void new_fp_exception(void) +{ + if (++erl_fp_exception > 50) { + fprintf(stderr, "SIGFPE loop detected, bailing out\n"); + exit(1); + } +} + /* Is there no standard identifier for Darwin/MacOSX ? */ #if defined(__APPLE__) && defined(__MACH__) && !defined(__DARWIN__) #define __DARWIN__ 1 @@ -18540,7 +18553,7 @@ static void fpe_sig_action(int sig, sigi fpstate->mxcsr = 0x1F80; fpstate->sw &= ~0xFF; #endif - erl_fp_exception = 1; + new_fp_exception(); } static void do_init(void) @@ -18557,7 +18570,7 @@ static void do_init(void) static void fpe_sig_handler(int sig) { - erl_fp_exception = 1; + new_fp_exception(); } static void do_init(void) ________________________________________________________________ erlang-questions mailing list.
