Description
Hi,
nginx 1.5.10 segfaults on Solaris 11.1 x86/amd64 when compiled with -m64:
./configure --with-cc=/opt/solarisstudio12.3/bin/cc --with-cc-opt="-m64 -g" --with-ld-opt="-m64" ... vi objs/Makefile # remove -fast -xipo gmake ... cd objs dbx nginx (dbx) run -t Running: nginx -t (process id 25357) signal SEGV (no mapping at the fault address) in ngx_time_update at line 83 in file "ngx_times.c" 83 if (!ngx_trylock(&ngx_time_lock)) { (dbx) where =>[1] ngx_time_update(), line 83 in "ngx_times.c" [2] ngx_time_init(), line 69 in "ngx_times.c" [3] main(argc = 2, argv = 0xffff80ffbffff498), line 272 in "nginx.c" (dbx) list 83 if (!ngx_trylock(&ngx_time_lock)) { 84 return; 85 } 86 87 ngx_gettimeofday(&tv); 88 89 sec = tv.tv_sec; 90 msec = tv.tv_usec / 1000; 91 92 ngx_current_msec = (ngx_msec_t) sec * 1000 + msec;
No segfault when compiling with -m32…
Note:
See TracTickets
for help on using tickets.
With the parameters you've supplied, nginx will assume it's building 32-bit binary and will use 32-bit assembler code for atomic instructions (
src/os/unix/ngx_sunpro_x86.il
), while 64-bit one is actually required (src/os/unix/ngx_sunpro_amd64.il
). This expectedly results in problems.Solution is to use
--with-cpu-opt=amd64
instead of adding-m64
to ld/cc options manually, like this:It will configure things correctly for you.
