iconv-go升级过程中的编译问题

 

工作项目原因,需要对golang进行升级。升级之后老的iconv-go运行有问题。因为新的golang运行更加严格,所以需要升级iconv-go.

从djimenez/iconv-go 拉下来代码进行编译发现“找不到iconv库的一些接口”,目测是库没链进来。错误信息如下:

go install ./...
# github.com/djimenez/iconv-go

collect2: ld returned 1 exit status

很奇怪,本地明明有安装iconv,怎么就找不到iconv库?

iconv --version

进到iconv-go的converter.go发现

package iconv

/*
#cgo darwin LDFLAGS: -liconv
#cgo freebsd LDFLAGS: -liconv
#cgo windows LDFLAGS: -liconv
#include <stdlib.h>
#include <iconv.h>

// As of GO 1.6 passing a pointer to Go pointer, will lead to panic
// Therofore we use this wrapper function, to avoid passing **char directly from go
size_t call_iconv(iconv_t ctx, char *in, size_t *size_in, char *out, size_t *size_out){
        return iconv(ctx, &in, size_in, &out, size_out);
}

*/

我了个去,darwinfreebsd,windows都有。但是我在centos下使用的。难不成是这个原因,导致iconv库没有链进去?于是尝试进行了修改。

package iconv

/*
#cgo darwin LDFLAGS: -liconv
#cgo freebsd LDFLAGS: -liconv
#cgo windows LDFLAGS: -liconv
#cgo LDFLAGS: -liconv
#include <stdlib.h>
#include <iconv.h>

// As of GO 1.6 passing a pointer to Go pointer, will lead to panic
// Therofore we use this wrapper function, to avoid passing **char directly from go
size_t call_iconv(iconv_t ctx, char *in, size_t *size_in, char *out, size_t *size_out){
        return iconv(ctx, &in, size_in, &out, size_out);
}

*/

再进行编译。奇迹般的通过了,通过了,通过了。。。

好吧,目前只是这样猥琐的解决的。这样写不知道会不会对跨平台造成影响。先这样解决吧。记录一下。

如果哪位同仁看到这篇文章,觉得不是这样解决的,请不吝赐教。
