c++ - 如何通过 autoconf/automake 对 boost 库/ header 包含进行故障排除？

Question

我是 autom4te 的新手，我正在尝试使用 autoconf/automake 在多个体系结构上构建和链接 C++ 程序。使链接复杂化的是项目需要 boost (文件系统、系统、程序选项)这一事实。

我正在使用 boost.m4(来自 http://github.com/tsuna/boost.m4/tree/ )，它似乎成功地找到了所有库和 header 。

不幸的是，链接仍然失败，让我很困惑。

这些是configure.ac的相关行:

AC_CONFIG_MACRO_DIR([m4])
# ...
AC_PROG_CXX
AC_PROG_LIBTOOL
# ...
BOOST_REQUIRE([1.41.0])
BOOST_FILESYSTEM
BOOST_SYSTEM
BOOST_PROGRAM_OPTIONS
# ...

在 src/Makefile.am 中:

bin_PROGRAMS = phenomatrix
phenomatrix_CXXFLAGS = $(BOOST_CPPFLAGS)
phenomatrix_LDFLAGS = $(BOOST_LDFLAGS) $(BOOST_SYSTEM_LDFLAGS) $(BOOST_FILESYSTEM_LDFLAGS) $(BOOST_PROGRAM_OPTIONS_LDFLAGS) # $(BOOST_SYSTEM_LIB) $(BOOST_PROGRAM_OPTIONS_LIB) $(BOOST_FILESYSTEM_LIB)
phenomatrix_LIBS = $(BOOST_SYSTEM_LIBS) $(BOOST_FILESYSTEM_LIBS) $(BOOST_PROGRAM_OPTIONS_LIBS)
phenomatrix_SOURCES = adjacency_list.cpp distance.cpp genephene.cpp knearest.cpp marshall.cpp oracle.cpp type_shield.cpp avgmindist.cpp euclidean.cpp hypergeometric.cpp main.cpp mindist.cpp partialbayes.cpp utilities.cpp

这些没有错误，它甚至设法找到库和 header :

checking for Boost headers version >= 104100... yes
checking for Boost's header version... 1_41
checking for the toolset name used by Boost for g++... gcc44 -gcc

checking boost/program_options.hpp usability... yes
checking boost/program_options.hpp presence... yes
checking for boost/program_options.hpp... yes
checking for the Boost program_options library... yes

但是，当我运行 make 时，出现错误:

libtool: link: g++ -g -O2 -o phenomatrix phenomatrix-adjacency_list.o phenomatrix-distance.o phenomatrix-genephene.o phenomatrix-knearest.o phenomatrix-marshall.o phenomatrix-oracle.o phenomatrix-type_shield.o phenomatrix-avgmindist.o phenomatrix-euclidean.o phenomatrix-hypergeometric.o phenomatrix-main.o phenomatrix-mindist.o phenomatrix-partialbayes.o phenomatrix-utilities.o  -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib

/usr/local/include/boost/system/error_code.hpp:216: undefined reference to `boost::system::get_system_category()'

重复广告令人作呕。

我什至不确定如何进行测试以查看它是否包含正确的目录。是的，我知道 g++ 上有一个 -t 标志，但我不知道如何传递它(从 autom4te 内部)。

我认为这与同一台机器上的多个版本的 boost 库和 header 有关，对此我无能为力。

它没有编译，因为它的库没有正确设置...脚本没有正确配置 -lboost_libraryname 选项。

$(BOOST_PROGRAM_OPTIONS_LIB) -> $(BOOST_PROGRAM_OPTIONS_LIBS) in tyour makefil.am your_program_LDFLAGS

以下存储库中的 ax_boost_***.m4 脚本对我来说运行良好:
