我想使用densepose，根据安装情况，我需要安装gcc4.9.2。我已经下载了gcc-4.9.2.tar.gz和先决条件。然后运行配置
../gcc-4.9.2/configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
这是配置结果

我没有C++/C编译的经验，希望有人能帮我。我原来的gcc版本是4.8.5；cmake版本3.6.2。
我已经为这个错误搜索了很多。由于没有人回答，我自己回答，以防其他人也有同样的错误。总之，这是一个与pthread_mutex_t变量有关的错误。此变量的定义和初始化不兼容。
首先，检查pthread.h和pthreadtypes.h 的位置
locate pthread.h
locate pthreadtypes.h
在我的例子中，我在不同的位置有两个pthread.h文件。通常，/usr/include下的文件是编译过程中使用的文件。检查PTHREAD_MUTEX_INITIALIZER的定义。应该是这样的：
{{0, 0, 0, 0, 0, 0, {0, 0}}}
或者使用#ifdef定义，但它们几乎是一样的。
然后检查pthreadtypes.h。通常，它位于/usr/include/bits下。找到pthread_mutex_t的定义。一个版本(1.0版(可能看起来像这样：
typedef union
{
struct __pthread_mutex_s __data;
char __size[__SIZEOF_PTHREAD_MUTEX_T];
long int __align;
} pthread_mutex_t;
另一个版本(2.0版(：
typedef union
{
struct __pthread_mutex_s
{
int __lock;
unsigned int __count;
int __owner;
#if __WORDSIZE == 64
unsigned int __nusers;
#endif
/* KIND must stay at this position in the structure to maintain
binary compatibility. */
int __kind;
#if __WORDSIZE == 64
int __spins;
__pthread_list_t __list;
# define __PTHREAD_MUTEX_HAVE_PREV 1
#else
unsigned int __nusers;
__extension__ union
{
int __spins;
__pthread_slist_t __list;
};
#endif
} __data;
char __size[__SIZEOF_PTHREAD_MUTEX_T];
long int __align;
} pthread_mutex_t;
您可以看到第二个要长得多，并在并集中定义一个具有"｛｝"的结构。这就是为什么错误信息一直说在初始化时无法将"转换为"short int"。原因是PTHREAD_MUTEX_INITIALIZER在并集中用{}初始化了PTHREAD_MUTEX_t。但是，如果您的定义看起来像ver1.0，那么冲突就在这里。然后您可以将定义替换为ver2.0。
这也可能与您的GNU版本有关。1.0版本的定义似乎适用于较新的版本。
