在centos7上从源代码编译gcc4.9.2
compile gcc4.9.2 from source on centos7
我想用densepose，根据安装需要安装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
这里是配置结果

我没有C++/C编译经验，希望有人能帮助我。
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，以防其他人有同样的错误。
总之，这是一个与名为 pthread_mutex_t 的变量相关的错误。
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
就我而言，我在不同位置有两个 pthread.h 文件。
通常，/usr/include下的是编译过程中使用的文件。
检查 PTHREAD_MUTEX_INITIALIZER 的定义。
它应该是这样的：
{{0, 0, 0, 0, 0, 0, {0, 0}}}
或者用#ifdef定义，但它们几乎是一回事。
然后检查pthreadtypes.h。通常，它低于 /usr/include/位。
找到 pthread_mutex_t 的定义。
一个版本 (ver1.0) 可能如下所示：
typedef union
{
struct __pthread_mutex_s __data;
char __size[__SIZEOF_PTHREAD_MUTEX_T];
long int __align;
} pthread_mutex_t;
另一个版本（ver2.0）：
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;
可以看到第二个要长很多，在union中定义一个带'{}'的struct。所以报错信息一直说cannot convert ‘’ to ‘short int’ in initialization。原因是 PTHREAD_MUTEX_INITIALIZER 在联合中用 {} 初始化了 pthread_mutex_t。
但是，如果您有看起来像 ver1.0 的定义，那么这里就是冲突。那么您可以将定义替换为 ver2.0.
这也可能与您的GNU版本有关。 ver1.0 定义似乎适用于较新的版本。

我没有C++/C编译经验，希望有人能帮助我。 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，以防其他人有同样的错误。 总之，这是一个与名为 pthread_mutex_t 的变量相关的错误。 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
就我而言，我在不同位置有两个 pthread.h 文件。 通常，/usr/include下的是编译过程中使用的文件。 检查 PTHREAD_MUTEX_INITIALIZER 的定义。 它应该是这样的：
{{0, 0, 0, 0, 0, 0, {0, 0}}}
或者用#ifdef定义，但它们几乎是一回事。
然后检查pthreadtypes.h。通常，它低于 /usr/include/位。 找到 pthread_mutex_t 的定义。 一个版本 (ver1.0) 可能如下所示：
typedef union
{
struct __pthread_mutex_s __data;
char __size[__SIZEOF_PTHREAD_MUTEX_T];
long int __align;
} pthread_mutex_t;
另一个版本（ver2.0）：
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;
可以看到第二个要长很多，在union中定义一个带'{}'的struct。所以报错信息一直说cannot convert ‘’ to ‘short int’ in initialization。原因是 PTHREAD_MUTEX_INITIALIZER 在联合中用 {} 初始化了 pthread_mutex_t。 但是，如果您有看起来像 ver1.0 的定义，那么这里就是冲突。那么您可以将定义替换为 ver2.0.
这也可能与您的GNU版本有关。 ver1.0 定义似乎适用于较新的版本。
