c++ - ブーストロガーのリンクの問題

Question

Boost ライブラリを使用するプログラムを作成しています。プログラムオプションのリンクと使用には問題はありませんでしたが、ブーストログを正しく機能させることができないようです。何が欠けているのか誰か教えてもらえますか?

jamroot.jam

using clang : : : <compileflags>-Isrc/main/headers <compileflags>-std=c++11 <compileflags>-stdlib=libc++ <linkflags>-std=c++11 <linkflags>-stdlib=libc++ ;
lib boost_program_options boost_log ;
exe foghorn : [ glob src/main/cpp/*.cpp ] boost_program_options boost_log ;

これは私が得ているエラーです:

Answer 1

私は同じ問題を抱えていました.私の場合、動的ライブラリのみでブーストコンパイルし、BOOST_ALL_DYN_LINK.

http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/rationale/namespace_mangling.html

試しにコンパイルしてみる

http://www.boost.org/doc/libs/1_54_0/libs/log/example/doc/tutorial_fmt_stream.cpp

（#include <boost/log/support/date_time.hpp>追加する必要があります。例は壊れています。）

また、追加します#define BOOST_LOG_DYN_LINK

例をコンパイルできますg++ tutorial_fmt_stream.cpp -Wall -L$BOOST/lib/ -I $BOOST/include/ -pthread -lboost_system -lboost_log_setup -lboost_log -lboost_date_time -lboost_thread -lrt -lboost_filesystem

Answer 2

ブーストの管理に を使用している場合はcmake、次のようなものを用意することを忘れないでください:

add_definitions(-DBOOST_LOG_DYN_LINK)

あなたのCMakeLists.txt

Answer 3

私は同じ問題を抱えていましたが、それは複雑なリンケージパスでした。このメッセージは、 が静的ライブラリ ( ....v2s ...) とリンクしようとしていることを示していますが、リンカーは動的ライブラリのみを提供しています (愚かなため)。

Boost のビルドが.soと.aファイルの両方を生成している可能性があり、両方が存在すると gcc が混乱します。

CMake静的 Boost ライブラリを使用するライブラリを構築しました。フローを使用してこのライブラリをプログラムにリンクする場合Makefile、プログラムは同じ静的 Boost ライブラリも指定する必要があります。ただし、-lリンカーのオプションはあいまいであり、ここではあなたの友人ではありません. 静的 (.a) と動的 (.so) の両方の出力を持つように Boost をビルドした場合、-lオプションを使用するだけでは、リンカーは最初に動的 (.so) ファイルを選択します。

回避策は、-Lおよび-lオプションを使用して Boost スタティック ライブラリを検索するのではなく (失敗するため)、Boost ライブラリへのフル パスを指定することです。例えば、

gcc .... -L/opt/boost_1.55/lib -lboost_log

への変更

gcc .... /opt/boost_1.55/lib/libboost_log.a

別のオプションは、単語-staticを gcc に指定することですが、これにはすべてのライブラリが静的である必要があり、boost 以外のもの (librt.so ライブラリなど) を使用するとおそらく機能しません。
