如何使用代码块为MIGW构建64位版本的Oracle OCI静态库(libocia/w/m.a)

How to build 64 bit version of Oracle OCI static libraries (libocia/w/m.a) for MIGW using Code blocks?

有人知道如何构建64位版本的Oracle OCI静态库吗?

我从http://sourceforge.net/projects/orclib/files/下载了ocilib-3.12.1-windows.zip (2.9 MB)

得到这个ocilib_static_lib_mingw。/proj文件夹下的CBP项目。它在Migw GCC 32位下编译良好。但是，它不能在64位Migw下编译GCC 64位

-------------- Build: Release - ANSI in ocilib_static_lib_mingw (compiler: Mingw/TDM 64)---------------

C: ocilib src oci_types.h 

#ifdef _WIN64
  #ifndef lint
253: typedef unsigned _int64 ubig_ora;
254: typedef   signed _int64 sbig_ora;
  #else
    #define ubig_ora unsigned _int64
    #define sbig_ora signed _int64
  #endif

我没有关于"expected " = "…"错误的线索

I看起来像是检测到Windows平台，因此假设使用了MSVC编译器。旧版本的MSVC不支持int64_t这样的类型定义(但它们有自己的INT64或_int64版本)。因为你的项目是纯C(没有c++)

像这样做:

#ifdef _WIN64
# if defined(_MSC_VER)
#   ifndef lint
typedef unsigned _int64 ubig_ora;
typedef   signed _int64 sbig_ora;
#   else
#   define ubig_ora unsigned _int64
#   define sbig_ora signed _int64
#   endif
# elif defined(__MINGW64__)    
#   include <stdint.h>
typedef uint64_t ubig_ora;
typedef int64_t sbig_ora;
# endif
...
