Не удается связать libsqlite3.so в НКУ

Question

Я пытаюсь собрать следующую программу с GCC 4.8.2 на Ubuntu 14.04.1 с пакетом libsqlite3-dev установлены:

#include <sqlite3.h> 

int main(int argc, char *argv[]) 
{ 
    struct sqlite3 *s3; 
    char *filename = ":memory:"; 
    sqlite3_open(filename, &s3); 
    return 0; 
} 

Когда работает gcc -L/usr/lib/x86_64-linux-gnu -lsqlite3 program.c я в ошибка:

/tmp/ccjvJqkW.o: In function `main': 
program.c:(.text+0x26): undefined reference to `sqlite3_open' 
collect2: error: ld returned 1 exit status 

Он смотрит на меня, как я установил правильную библиотеку:

autobound@Calcium:~$ locate libsqlite3.so 
/usr/lib/i386-linux-gnu/libsqlite3.so.0 
/usr/lib/i386-linux-gnu/libsqlite3.so.0.8.6 
/usr/lib/x86_64-linux-gnu/libsqlite3.so 
/usr/lib/x86_64-linux-gnu/libsqlite3.so.0 
/usr/lib/x86_64-linux-gnu/libsqlite3.so.0.8.6 

autobound@Calcium:~$ readelf -a /usr/lib/x86_64-linux-gnu/libsqlite3.so | grep sqlite3_open 
    71: 00000000000947b0  5 FUNC GLOBAL DEFAULT 11 sqlite3_open_v2 
    157: 00000000000947a0 12 FUNC GLOBAL DEFAULT 11 sqlite3_open 
    194: 00000000000947c0 181 FUNC GLOBAL DEFAULT 11 sqlite3_open16 

Запуск clang с теми же аргументами (clang -L/usr/lib/x86_64-linux-gnu -lsqlite3 program.c) строит исполняемый файл просто отлично. Фактически, аргумент -L не равен , который необходим для создания клана.

подробный вывод НКУ является:

autobound@Calcium:~/src/c/sqlitetest (master)$ gcc --verbose -L/usr/lib/x86_64-linux-gnu -lsqlite3 program.c

Попробуйте изменить порядок параметров

gcc program.c -L/usr/lib/x86_64-linux-gnu -lsqlite3
