用uclibc库编译mythTV注意事项

首先，uclibc库从何而来？

找到buildroot开源项目，根据自己的需要进行配置，我的配置如下：

同时我们需要修改uclibc目录libpthread/linuxthreads.old下的attr.c文件，在这个文件结尾增加下面的语句：

 

extern int *__libc_stack_end; // weak_alias (__pthread_attr_getstacksize, pthread_attr_getstacksize) void* pthread_getattr_np(pthread_t thread, pthread_attr_t *attr) { static void *stackBase = 0; static size_t stackSize = 0; int ret = 0; /* Stack size limit. */ struct rlimit rl; /* The safest way to get the top of the stack is to read /proc/self/maps and locate the line into which __libc_stack_end falls. */ FILE *fp = fopen("/proc/self/maps", "rc"); if (fp == NULL) ret = errno; /* We need the limit of the stack in any case. */ else if (getrlimit (RLIMIT_STACK, &rl) != 0) ret = errno; else { /* We need no locking. */ __fsetlocking (fp, FSETLOCKING_BYCALLER); /* Until we found an entry (which should always be the case) mark the result as a failure. */ ret = ENOENT; char *line = NULL; size_t linelen = 0; uintptr_t last_to = 0; while (! feof_unlocked (fp)) { if (getdelim (&line, &linelen, '/n', fp) <= 0) break; uintptr_t from; uintptr_t to; if (sscanf (line, "%x-%x", &from, &to) != 2) continue; if (from <= (uintptr_t) __libc_stack_end && (uintptr_t) __libc_stack_end < to) { /* Found the entry. Now we have the info we need. */ attr->__stacksize = rl.rlim_cur; #ifdef _STACK_GROWS_UP /* Don't check to enforce a limit on the __stacksize */ attr->__stackaddr = (void *) from; #else attr->__stackaddr = (void *) to; /* The limit might be too high. */ if ((size_t) attr->__stacksize > (size_t) attr->__stackaddr - last_to) attr->__stacksize = (size_t) attr->__stackaddr - last_to; #endif /* We succeed and no need to look further. */ ret = 0; break; } last_to = to; } fclose (fp); free (line); } #ifndef _STACK_GROWS_UP stackBase = (char *) attr->__stackaddr - attr->__stacksize; #else stackBase = attr->__stackaddr; #endif stackSize = attr->__stacksize; return (void*)(stackBase + stackSize); } int __pthread_attr_getstack (const pthread_attr_t *attr, void **stackaddr, size_t *stacksize) { /* XXX This function has a stupid definition. The standard specifies no error value but what is if no stack address was set? We simply return the value we have in the member. */ #ifndef _STACK_GROWS_UP *stackaddr = (char *) attr->__stackaddr - attr->__stacksize; #else *stackaddr = attr->__stackaddr; #endif *stacksize = attr->__stacksize; return 0; } weak_alias (__pthread_attr_getstack, pthread_attr_getstack)

 

还有libpthread/linuxthreads.old/sysdeps/pthread/pthread.h文件，需要做如下修改：

//#if 0 /* Not yet implemented in uClibc! */ #ifdef __USE_GNU /* Initialize thread attribute *ATTR with attributes corresponding to the already running thread TH. It shall be called on uninitialized ATTR and destroyed with pthread_attr_destroy when no longer needed. */ //extern int pthread_getattr_np (pthread_t __th, pthread_attr_t *__attr) __THROW; extern void* pthread_getattr_np(pthread_t thread, pthread_attr_t *attr); #endif //#endif /* Return the previously set address for the stack. */ extern int pthread_attr_getstack (__const pthread_attr_t *__restrict __attr, void **__restrict __stackaddr, size_t *__restrict __stacksize) __THROW;

 

另外，需要对mythtv-0.22打补丁，补丁如下：
