針對Boost.Log的g ++靜態鏈接錯誤

Question

靜態鏈接到Boost.Log時出現鏈接錯誤。編譯器版本是g ++ 4.8.1。升級版本是1.55.0。 我可以做一個沒有問題的動態鏈接（在make文件中有一個「-DBOOST_LOG_DYN_LINK」），但是當我進行靜態鏈接時，會出現鏈接錯誤。這個問題不會發生在其他boost庫上。我簡化了我的代碼重現此問題很容易：

#include <boost/log/trivial.hpp> 
int main() 
{ 
    BOOST_LOG_TRIVIAL(trace) << "test trace"; 
    return 0; 
} 

生成鏈接錯誤構建命令：

g++ test.cpp -lboost_thread -lboost_log 

但是，如果我明確指定的lib文件，不會有問題：

g++ test.cpp -lboost_thread /usr/local/lib/libboost_log.a 

我也嘗試添加-L選項，並得到同樣的錯誤回報：

g++ test.cpp -L/usr/local/lib -lboost_thread -lboost_log 

這裏的錯誤日誌：

Answer 1

你見過此頁：

http://www.boost.org/doc/libs/1_55_0/libs/log/doc/html/log/rationale/namespace_mangling.html

我建議你用正確的選項去提升日誌的配置頁面，讓您的項目再次。

Answer 2

我敢肯定，到目前爲止，您已經有了答案，但爲了以防萬一，您需要添加BOOST_LOG_DYN_LINK定義。

g++ -DBOOST_LOG_DYN_LINK logging_test.cpp -lboost_log -lpthread 

使用該命令，它應該現在運行。
