我試圖建立和安裝Apache節儉編譯器和庫錯誤:「的strdup」在此範圍

未聲明如圖指令運行./configure && make

而且我得到這個錯誤:

thrift 0.9.3

If something is missing that you think should be present, 
please skim the output of configure to find the missing 
component. Details are present in config.log.

我編輯了thrifty.yy並添加了#include <string.h>但我仍然得到了strdup丟失的錯誤。

src/thrifty.yy:1311:30: error: 'strdup' was not declared in this scope(同樣的錯誤,包括string.h中之前)

缺少什麼我在這裏?

在此先感謝!

那是cygwin的環境嗎? Woudl很高興知道......在這種情況下,請查看[THRIFT-2800](https://issues.apache.org/jira/browse/THRIFT-2800) – JensG

strdup不是標準的C函數。當編譯器被配置爲嚴格C兼容時,不允許在標準庫頭(如<string.h>)中轉儲自己的自定義非標準函數。

您可以通過更改編譯器來編譯非標準C代碼來解決此問題(例如,在gcc中,使用-std=gnu11而不是-std=c11編譯)。或替代,堅持純標準C.


...或只是實施的strdup自己,這是很容易:

#include <string.h> 
#include <stdlib.h> 

char* strdup (const char* s) 
{ 
    size_t slen = strlen(s); 
    char* result = malloc(slen + 1); 
    if(result == NULL) 
    { 
    return NULL; 
    } 

    memcpy(result, s, slen+1); 
    return result; 
}

將'strdup'的實現添加到'thrifty.yy'給出了更多的錯誤: '0.9.3/compiler/cpp/src/thrifty.yy:255.5:error:invalid character:'*' char * strdup const char * s) /c/University/InternetOfThings/thrift-0.9.3/compiler/cpp/src/thrifty.yy:255.14:error:invalid character:'(' char * strdup(const char * s) 我想它是一個C++編譯器,所以它不會識別指針 如何更改編譯器以編譯非標準C代碼 –

@TonyTannous不要使用C++編譯器編譯C代碼,沒有理由爲什麼C++編譯器不會識別指針,更有可能它不識別''但給出了錯誤的錯誤。 – Lundin

這不是我,我所做的只是按照說明中的./configure && make。 https://thrift.apache.org/tutorial/ –
