core dumping right off the bat

[eantoranz]

Hi!

I'm a newbie on hiphop and/or cmake so take it easy. I just finished compiling hphp on a precise (32-bit) box. When I try to run hphp, it symply core dumps:

$ ../src/hphp/hphp --help
Segmentation fault (core dumped)

Here's the last part of strace on it:

rt_sigaction(SIGQUIT, {0x89340b0, [QUIT], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
rt_sigaction(SIGILL, {0x89340b0, [ILL], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
rt_sigaction(SIGFPE, {0x89340b0, [FPE], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
rt_sigaction(SIGSEGV, {0x89340b0, [SEGV], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
rt_sigaction(SIGBUS, {0x89340b0, [BUS], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
rt_sigaction(SIGABRT, {0x89340b0, [ABRT], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigaction(SIGSEGV, {SIG_DFL, [SEGV], SA_RESTART}, {0x89340b0, [SEGV], SA_RESTART}, 8) = 0
futex(0xb66a2ea0, FUTEX_WAKE_PRIVATE, 2147483647) = 0
futex(0xb66c10fc, FUTEX_WAKE_PRIVATE, 2147483647) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV (core dumped) +++
Segmentation fault (core dumped)
$ echo $LD_LIBRARY_PATH
/usr/local/curl/lib/:/usr/local/libevent/lib/:/usr/local/onig/lib/

I'm not sure if it's because of laking correct environment variables.. .but these are the values I've exported:
$ echo $LD_LIBRARY_PATH
/usr/local/curl/lib/:/usr/local/libevent/lib/:/usr/local/onig/lib/
$ echo $HPHP_HOME
/home/antoranz/Descargas/php/facebook-hiphop-php-cf9b612/
$ echo $HPHP_LIB
/home/antoranz/Descargas/php/facebook-hiphop-php-cf9b612/bin/

Thanks in advance.

The problem could have started right before that:

munmap(0xb76fc000, 4096) = 0
futex(0xb6675c60, FUTEX_WAKE_PRIVATE, 2147483647) = 0
open("/etc/hosts", O_RDONLY|O_CLOEXEC) = 4
fstat64(4, {st_mode=S_IFREG|0644, st_size=296, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb76fc000
read(4, "127.0.0.1\tlocalhost\n127.0.1.1\tpi"..., 4096) = 296
read(4, "", 4096) = 0
close(4) = 0
munmap(0xb76fc000, 4096) = 0
time(NULL) = 1338242128
open("/sys/devices/system/cpu/online", O_RDONLY|O_CLOEXEC) = 4
read(4, "0-1\n", 8192) = 4
close(4) = 0

Then it started with what I wrote before:
rt_sigaction(SIGQUIT, {0x89340b0, [QUIT], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
rt_sigaction(SIGILL, {0x89340b0, [ILL], SA_RESTART}, {SIG_DFL, [], 0}, 8) = 0
blah
blah

I'm wondering if it's something with that file? The file is there and it's readable and the content is 0-1.

Maybe an incompatible extension. Hiphop is coded for 64-bit support only, all 32-bit support is provided by the community only. Try removing some extensions and seeing it it still happens.
