Android NDK:无法解析功能va_start/va_end [英] Android NDK: Function va_start / va_end could not be resolved

问题描述

我试图在我的项目中使用va_start和va_end函数，但是eclipse不想将其解析为函数. gcc编译整个项目而没有错误...

I trying to use va_start and va_end functions in my project, but eclipse don't want to resolve it as functions. gcc compiles whole project without errors...

[myfile.cpp]

[myfile.cpp]

#include <stdio.h>
#include <stdarg.h>
[...]
inline void ShowDbgMsg( const char* str, ... )
{
    va_list argptr;
    va_start(argptr, str);
    vprintf(str, argptr);
    va_end(argptr);
}
[...]

[Android.mk]

[Android.mk]

[...]
LOCAL_C_INCLUDES := jni/pvrTools/ jni/igel/ $(STLPORT_BASE)/stlport
[...]

Eclipse说:

[...]
Description Resource    Path    Location    Type
Function 'va_start' could not be resolved   igel.comdef.h   /NativeProject/jni/igel    line 195 Semantic Error
Function 'va_end' could not be resolved igel.comdef.h   /NativeProject/jni/igel  line 203   Semantic Error
Function 'va_start' could not be resolved   igel.string.h   /NativeProject/jni/igel line 341    Semantic Error
Function 'va_end' could not be resolved igel.string.h   /NativeProject/jni/igel line 351    Semantic Error
[...]

因此，看来Eclipse无法找到某些东西...如何解决此问题? 预先感谢！

So, it looks like Eclipse unable to locate something... How to solve this issue? Thanks in advance!

P.S.>项目->索引->重建无济于事. :(

推荐答案

我通过使用嵌入式编译器功能替换va_ *代码来解决此问题:

I solve this issue by replacing my va_* code with embedded compiler features:

#ifdef IGEL_PLATFORM_ANDROID
#   define ShowDbgMsg(...)  ((void)__android_log_print(ANDROID_LOG_INFO, "igel-debug", __VA_ARGS__))
#else
inline void ShowDbgMsg( const char* str, ... )
{
    va_list argptr;
    va_start(argptr, str);
    vprintf(str, argptr);
    va_end(argptr);
}
#endif // IGEL_PLATFORM_ANDROID

我知道这不是一个好的解决方案，但是它可以工作.

I know it's not a good solution, but it works.
