我想從DocxFactory編譯一個最小的例子。該示例取自C++ Tutorial。編譯基於DocxFactory的應用程序與gcc
其中執行以下步驟:
- 下載DocxFactory library for 64-bit Linux
- 提取物和作爲C++ Tutorial
- 此後描述安裝該庫中,示例創建文件(top_level.cpp)
top_level.cpp:
#include "WordProcessingCompiler.h"
#include <exception>
#include <iostream>
#include <ctime>
using namespace DocxFactory;
using namespace std;
int main()
{
try
{
WordProcessingCompiler& l_compiler =
WordProcessingCompiler::getInstance();
time_t l_start = clock();
l_compiler.compile(
"/opt/DocxFactory/exercises/templates/top_level_items.docx",
"/opt/DocxFactory/exercises/templates/top_level_items.dfw");
cout<< "Completed (in "
<< (double) (clock() - l_start)/CLOCKS_PER_SEC
<< " seconds)."
<< endl;
}
catch (const exception& p_exception)
{
cout << p_exception.what() << endl;
}
}
之後,它會被編譯,寫在本教程中,有:
g++ -c top_level.cpp /opt/DocxFactory/src/WordProcessingCompiler.cpp /opt/DocxFactory/src/WordProcessingMerger.cpp -I/opt/DocxFactory/include
最後的鏈接失敗,
g++ -o top_level top_level.o WordProcessingCompiler.o WordProcessingMerger.o -L/opt/DocxFactory/lib -lDocxFactory
//opt/DocxFactory/lib/libDocxFactoryLib.so: undefined reference to `ZBarcode_Export'
collect2: error: ld returned 1 exit status
因爲這是一個鏈接錯誤,很顯然,一個或多個缺少額外的動態庫。
問題
- 別的任何人運行到同樣的問題,解決它了嗎?
- 什麼庫包含名稱爲ZBarcode_Export的函數或類?
