爲什麼autoconf沒有正確檢測到提升？

Question

我使用的autoconf檢測Boost庫，與之相配套的autoconf-archive macros，他們正常工作與全系統的Boost庫，但失敗，如果我手工編譯升壓在我的主目錄：

sb@stephane:~/devel/spectra2$ ./configure --with-boost=/home/sb/local/ 
checking for a BSD-compatible install... /usr/bin/install -c 
checking whether build environment is sane... yes 
checking for a thread-safe mkdir -p... /bin/mkdir -p 
checking for gawk... no 
checking for mawk... mawk 
checking whether make sets $(MAKE)... yes 
checking build system type... i686-pc-linux-gnu 
checking host system type... i686-pc-linux-gnu 
checking for style of include used by make... GNU 
checking for gcc... gcc 
checking for C compiler default output file name... a.out 
checking whether the C compiler works... yes 
checking whether we are cross compiling... no 
checking for suffix of executables... 
checking for suffix of object files... o 
checking whether we are using the GNU C compiler... yes 
checking whether gcc accepts -g... yes 
checking for gcc option to accept ISO C89... none needed 
checking dependency style of gcc... gcc3 
checking for library containing strerror... none required 
checking for g++... g++ 
checking whether we are using the GNU C++ compiler... yes 
checking whether g++ accepts -g... yes 
checking dependency style of g++... gcc3 
checking for boostlib >= 1.31.0... yes 
checking whether the Boost::Program_Options library is available... yes 
checking for exit in -lboost_program_options... yes 
checking whether the Boost::Filesystem library is available... yes 
checking for exit in -lboost_filesystem... no 
checking for exit in -lboost_filesystem... (cached) no 
checking for exit in -lboost_filesystem... (cached) no 
configure: error: Could not link against boost_filesystem ! 

，你可以看，它檢測到一些庫很好，但它與boost文件系統失敗。這些是〜/ local/lib的內容：

sb@stephane:~$ ls -1 /home/sb/local/lib/ 
libboost_filesystem.a 
libboost_filesystem.so 
libboost_filesystem.so.1.42.0 
libboost_program_options.a 
libboost_program_options.so 
libboost_program_options.so.1.42.0 
libboost_system.a 
libboost_system.so 
libboost_system.so.1.42.0 
libboost_thread.a 
libboost_thread.so 
libboost_thread.so.1.42.0 

所以圖書館就在那裏。我試着用boost-1.39和boost-1.42都沒有不同的結果，爲什麼會出現這種情況？我忘了什麼嗎？

Answer 1

由於boost-1.39 libboost_filesystem依賴於libboost_system。在1.39之前，你只能鏈接到boost_filesystem，在以後的版本中你必須鏈接到它們兩個。

也許這與你的錯誤有關。

Answer 2

我發現boost.m4比Autoconf Macro Archive提供的Boost宏更強大。你可能有好運，只需遷移到boost.m4即可。
