The question is, how is libitm supposed to work on these systems? The configure.ac file contains: # Check to see if -pthread or -lpthread is needed. Prefer the former. # In case the pthread.h system header is not found, this test will fail. XPCFLAGS="" CFLAGS="$CFLAGS -pthread" AC_LINK_IFELSE( [AC_LANG_PROGRAM( [#include <pthread.h> void *g(void *d) { return NULL; }], [pthread_t t; pthread_create(&t,NULL,g,NULL);])], [XPCFLAGS=" -Wc,-pthread"], [CFLAGS="$save_CFLAGS" LIBS="-lpthread $LIBS" AC_LINK_IFELSE( [AC_LANG_PROGRAM( [#include <pthread.h> void *g(void *d) { return NULL; }], [pthread_t t; pthread_create(&t,NULL,g,NULL);])], [], [AC_MSG_ERROR([Pthreads are required to build libitm])])]) > Can't you just limit adding -pthread to Solaris 8 or something? I didn't invent anything here, this is exactly how -fopenmp/libgomp works. Just define GTM_SELF_SPECS to "" like Darwin and Windows. -- Eric Botcazou
