我编译不了iconv的程序,求助

balabalacha

iconv装在FB6.2

1. 
   
2. pkg_info | grep "iconv"
   
3. libiconv-1.9.2_2    A character set conversion library
   

复制代码

我先是用#include <sys/iconv.h>
编译提示:

1. 
   
2. cc -O2 -fno-strict-aliasing -pipe   main.c  -o main
   
3. In file included from main.c:3:
   
4. /usr/include/sys/iconv.h:94: error: syntax error before '*' token
   
5. *** Error code 1
   

复制代码

然后我又改成#include "/usr/local/include/iconv.h"
编译提示:

1. 
   
2. cc -O2 -fno-strict-aliasing -pipe   main.c  -o main
   
3. main.c: In function `main':
   
4. main.c:49: warning: passing arg 2 of `libiconv' from incompatible pointer type
   
5. /var/tmp//ccvgGXSD.o(.text+0x98): In function `main':
   
6. : undefined reference to `libiconv_open'
   
7. /var/tmp//ccvgGXSD.o(.text+0xbe): In function `main':
   
8. : undefined reference to `libiconv'
   
9. /var/tmp//ccvgGXSD.o(.text+0x138): In function `main':
   
10. : undefined reference to `libiconv'
    
11. /var/tmp//ccvgGXSD.o(.text+0x1af): In function `main':
    
12. : undefined reference to `libiconv_close'
    
13. /var/tmp//ccvgGXSD.o(.text+0x1f0): In function `main':
    
14. : undefined reference to `libiconv_close'
    
15. *** Error code 1

gvim

没有链接库
cc -O2 -fno-strict-aliasing -pipe -lxxx main.c  -o main
xxx大致应该是iconv

balabalacha

还是不行啊

gcc -O2 -fno-strict-aliasing -pipe -L /usr/obj/usr/src/sys/GOD/modules/usr/src/sys/modules/libiconv/ -liconv ~/test/iconv/main.c -o ~/test/iconv/code
/home/soj/test/iconv/main.c: In function `main':
/home/soj/test/iconv/main.c:49: warning: passing arg 2 of `libiconv' from incompatible pointer type
/usr/bin/ld: cannot find -liconv

dangk

-I/usr/local/include -L/usr/local/lib/ -liconv

嗨,终于行了,谢谢楼上.

BTW:为什么我用
#include <iconv.h>  报没有此文件
或者#include <sys/iconv.h>  则是报

1. 
   
2. In file included from main.c:3:
   
3. /usr/include/sys/iconv.h:94: error: syntax error before '*' token
   
4. main.c: In function `main':
   
5. main.c:16: error: syntax error before "c_pt"
   
6. main.c:36: error: `iconv_t' undeclared (first use in this function)
   
7. main.c:36: error: (Each undeclared identifier is reported only once
   
8. main.c:36: error: for each function it appears in.)
   
9. main.c:36: error: `c_pt' undeclared (first use in this function)

因为Freebsd自己也有iconv库。
而你实际在想要用的是gnu的iconv库。
