Bug #9436: r44670以降Solaris10でthread_pthread.cがコンパイルエラー

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.2.0dev (2014-01-21) [sparc64-solaris2.10]
• Backport: 1.9.3: DONTNEED, 2.0.0: DONTNEED, 2.1: DONTNEED

[ngoto (Naohisa Goto)]

r44670以降、Solaris10のccでは以下のエラーが出て失敗します。(以下はr44673にて確認)

cc -xO1 -xtarget=sparc64viiplus -m64 -DRUBY_EXPORT -I/usr/local/64/lib/libffi-3.0.10/include -I/usr/local/64/include -I. -I.ext/include/sparc64-solaris2.10 -I./include -I. -o thread.o -c thread.c
"thread_pthread.c", line 1488: missing operator
cc: acomp failed for thread.c
make: *** [thread.o] Error 2

thread_pthread.cの1488行め付近は以下のようになっています。

if TIMER_THREAD_STACK_MIN_SIZE < PTHREAD_STACK_MIN

undef TIMER_THREAD_STACK_MIN_SIZE

define TIMER_THREAD_STACK_MIN_SIZE PTHREAD_STACK_MIN

endif

Solaris10では、PTHREAD_STACK_MIN は /usr/include/limits.h にて以下のように定義されています。
#define PTHREAD_STACK_MIN ((size_t)_sysconf(_SC_THREAD_STACK_MIN))

つまり、PTHREAD_STACK_MINの実体は関数であり、定数ではありません。
このため、#if では使うことができずコンパイルエラーになります。
