我在CentOS 6.5中成功安装了pbc-0.5.14（http://crypto.stanford.edu/pbc/）。但是当我想安装pbc_sig-0.0.8（http://crypto.stanford.edu/pbc/sig/）时出现以下错误：
In file included from sig/bbs.c:2:
/usr/local/include/pbc/pbc_utils.h:82: error: expected ‘)’ before ‘i’
make[1]: *** [libpbc_sig_la-bbs.lo] Error 1
make[1]: Leaving directory `/root/Desktop/CryptographyLibraries/PBC/pbc_sig-0.0.8'
make: *** [all] Error 2
如果你能帮助我解决它，我将非常感激。我还带来了下面的./configure结果：

尝试在#include <pbc/pbc_utils.h>中切换第二行（#include "pbc_sig.h"）和三行（sig/bbs.c），看看是否能解决问题。
要解释此问题，因为这似乎已修复它，问题是pbc_utils.h标头文件不包含stdint.h但使用intptr_t类型。 sig/bbs.c同样没有包含该标题，pbc_sig.h也是如此。因此，重新排序包含意味着intptr_t在pbc_utils.h中看到它已被定义。
这可能会引起pbc背后的开发人员的注意，因为这可能被视为他们可能想要修复的头文件的问题。
