爲什麼Xsd無法加載代碼轉換服務？

Question

我正在使用CodeSynthesis XSD（用於C++的XML數據綁定工具）從.xsd文件自動生成.hpp和.cpp文件。

Could not load a transcoding service 

我使用openSUSE的跨越式42.2，XSD 4.0和Apache 3.1.4 Xercess：但在我的.xsd文件運行時XSD，我得到這個錯誤。下面是詳細信息：

Scanning dependencies of target XSDModel

lib/CMakeFiles/XSDModel.dir/build.make:51: recipe for target 'src/model/Model.cpp' failed

編輯1： 我已經建立的Apache Xercess與--enable-transcoder-gnuiconv開關和iconv安裝在我的機器上也是如此。

編輯2： 一些挖後，我發現，在我的Linux的echo $LANG命令打印一個空行。另外，運行localedef -i en_US -f UTF-8 en_US.UTF-8會打印此錯誤：

character map file `UTF-8' not found: No such file or directory 
cannot read character map directory `/usr/share/i18n/charmaps': No such file or directory 

Answer 1

在此Linux上沒有定義locale。所以，只需設置一個區域：

$ export LANG=LANG=en_US.UTF-8 

然後，一切都會好起來的。
