中文转换的问题，linux和hp unix平台

tempname_cn

int Convert(char* encFrom, char* encTo, const char* in, int in_len, char* out, int out_len) {         char* sin, *sout;         int ret;         iconv_t c_pt;         printf("1\n");         if((c_pt = iconv_open(encTo, encFrom)) == (iconv_t)-1)         {                 printf("c_pt == -1\n");                 return GBK_TO_UTF8_ERROR;         }         /*iconv(c_pt, NULL, NULL, NULL, NULL);*/         printf("2\n");         sin = (char*)in;         sout = (char*)out;         ret = iconv(c_pt, &sin, (size_t*)&in_len, &sout, (size_t*)&out_len);         printf("3\n");         if(ret == -1)         {                 printf("iconv error\n");                 iconv_close(c_pt);                 return GBK_TO_UTF8_ERROR;         }         printf("4\n");         iconv_close(c_pt);         return SUCCEED; }

在用hp15CN代理gbk后，

#0  0xc0000000000325f8 in _instantiate_iconv+0x58 () from /usr/lib/nls/iconv/pa20_64/methods.2/lhp15utf8.sl
(gdb) where
#0  0xc0000000000325f8 in _instantiate_iconv+0x58 () from /usr/lib/nls/iconv/pa20_64/methods.2/lhp15utf8.sl
#1  0xc000000000215200 in iconv+0x30 () from /usr/lib/pa20_64/libc.2
#2  0x4000000000018778 in Convert+0x100 ()
#3  0x400000000001cccc in ProcessFlightSupply+0x34c ()
#4  0x400000000000e07c in GetFlightSupplies+0x127c ()
#5  0x4000000000017e04 in main+0x11b4 ()


调用函数
Convert("hp15CN", "utf8", fli_sup->supplies_desc, sizeof(fli_sup->supplies_desc)+1, temp, sizeof(temp));

在linux是用gbk代替hp15CN的

高手指点下从数据库select出来的中文怎么在hp unix转换成utf8，谢谢了

tempname_cn

自己顶了，别沉了

net_robber

linux有个iconv可以gbk转utf8，但是不知道能不能直接从hp15CN转

另外hp有没有这个iconv我不太清楚

tempname_cn

我正在研究怎么在hp unix安装libiconv, 真是麻烦啊

tempname_cn

hp unix安装libiconv
我在hp unix装了libiconv,安装目录是/usr/local/
系统自带的iconv目录是/usr/include/iconv.h

我在头文件中用#include </usr/local/include/iconv.h>，但makefile仍然取了/usr/include/iconv.h，问问该怎么取/usr/local/include/iconv.

随便问下怎么连接，因为makefile自动去连接系统的库

I/opt/mqm/inc -o exdatass.o  -c exdatass.c
cc: "/usr/include/iconv.h", line 51: error 1584: Inconsistent type declaration: "libiconv_t".
*** Error exit code 1

原来一直以为是平台问题，现在发现用下面一段代码是成功的

#include <stdio.h> #include <stdlib.h> #include <string.h> #include <iconv.h> int Convert(char* encFrom, char* encTo, const char* in, int in_len, char* out, int out_len) { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char* sin, *sout; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;int ret; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iconv_t c_pt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("1\n"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if((c_pt = iconv_open(encTo, encFrom)) == (iconv_t)-1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("c_pt == -1\n"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return -1; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iconv(c_pt, NULL, NULL, NULL, NULL); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;sin = (char*)in; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;sout = (char*)out; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("2\n"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ret = iconv(c_pt, &sin, (size_t*)&in_len, &sout, (size_t*)&out_len); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("3\n"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(ret == -1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iconv_close(c_pt); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("iconv error\n"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return -1; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iconv_close(c_pt); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return 1; } int main() { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char buf[50]; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char* str = "1234 abc nimen"; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;memset(buf, '\0', sizeof(buf)); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Convert("hp15CN", "utf8", str, strlen(str)+1, buf, sizeof(buf)); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("buf = %s\n", buf); }

output:
1

3
buf = 1234 abc nimen


简单的测试代码成功了，可程序里的代码却会coredump，我要疯了
程序中的代码

int Convert(char* encFrom, char* encTo, const char* in, int in_len, char* out, int out_len) {         char* bufin = NULL;         char* bufout = NULL;         char* sin, *sout;         int ret;         iconv_t c_pt;         int ilen, olen;         printf("1\n");         if((c_pt = iconv_open(encTo, encFrom)) == (iconv_t)-1)         {                 printf("c_pt == -1\n");                 return GBK_TO_UTF8_ERROR;         }         iconv(c_pt, NULL, NULL, NULL, NULL);         printf("2\n");         bufin = (char*)malloc(in_len);         if(bufin == NULL)                 return  GBK_TO_UTF8_ERROR;         memset(bufin, '\0', sizeof(bufin));         /*strcpy(bufin, in);*/         strcpy(bufin, "wo men ke");         printf("in str len = %d\n", strlen(in));         printf("bufin=%s\n", bufin);         sin = bufin;         sout = bufout;         ilen = strlen(bufin)+1;         olen = 495;         printf("3\n");         printf("sin=%s, sout=%s, ilen=%d, olen=%d\n", sin, out, ilen, olen); ret = iconv(c_pt, &sin,(size_t*)&ilen, &sout, (size_t*)&olen);         printf("4\n");         if(ret == -1)         {                 iconv_close(c_pt);                 if(bufin != NULL)                 {                         free(bufin);                         bufin = NULL;                 }                 printf("iconv error\n");                 return GBK_TO_UTF8_ERROR;         }         if(bufin != NULL)         {                 free(bufin);                 bufin = NULL;         }         iconv_close(c_pt);         return SUCCEED; }

output：
1
2
in str len = 22
bufin=wo men ke
3
sin=wo men ke, sout=, ilen=10, olen=495
Bus error(coredump)

哎，问题还没有解决，接着顶

用iconv -l命令看看系统支持哪些字符集先
