have error when build mini_httpd : previous declaration of ‘getline’ was here

mini_httpd官網

編譯mini_httpd

1. wget http://www.acme.com/software/mini_httpd/mini_httpd-1.19.tar.gz
2. tar zxvf mini_httpd-1.19.tar.gz
3. cd mini_httpd-1.19/
4. make

出現錯誤

htpasswd.c:52: error: conflicting types for ‘getline’

/usr/include/stdio.h:651: note: previous declaration of ‘getline’ was here

htpasswd.c: In function ‘add_password’:

htpasswd.c:117: warning: ignoring return value of ‘fgets’, declared with attribute warn_unused_result

htpasswd.c: In function ‘main’:

htpasswd.c:216: warning: ignoring return value of ‘system’, declared with attribute warn_unused_result

make: *** [htpasswd.o] Error 1

htpasswd.c第52行所宣告的名字getline與/usr/include/stdio.h +651命名相同

以下是/usr/include/stdio.h部分內容

/* Like `getdelim', but reads up to a newline.

   This function is not part of POSIX and therefore no official

   cancellation point.  But due to similarity with an POSIX interface

   or due to the implementation it is a cancellation point and

   therefore not marked with __THROW.  */

extern _IO_ssize_t getline (char **__restrict __lineptr,

                size_t *__restrict __n,

                FILE *__restrict __stream) __wur;

#endif

修改方式將htpasswd.c第52行函數命名方式修改 from getline to getlinexxx

另外第192行也需要修改

重新編譯

make clean

make

OK

最後訊息

gcc -O   -c match.c

gcc -O   -c tdate_parse.c

gcc -O   -s mini_httpd.o match.o tdate_parse.o   -lcrypt -o mini_httpd

gcc -O   -c htpasswd.c

htpasswd.c: In function ‘add_password’:

eclipse無法識別小米2

這篇提供解決方法

1. 安裝驅動程式 (按照小米手機內建教學就可以正確安裝)
2. 撥號介面下輸入以下密碼 *#*#717717#*#*
