通过SConstruct链接到boost [英] Linking to boost through SConstruct

问题描述

我试图在一个跨平台项目中使用boost来执行文件/目录操作。我一直在使用visual studio，但为了在linux上编译，我决定切换到SConstruct。

I'm trying to work on a cross-platform project that uses boost for the file/directory operations. I've been using visual studio, but in order to compile on linux, I've decided to switch to SConstruct.

我不能[正确]链接到文件系统

I cannot [correctly?] link to the filesystem library however.

我的SConstruct文件如下：

my SConstruct file is as follow:

vLibs = [   
            'libboost_system-vc100-mt-1_44.lib',
            'libboost_filesystem-vc100-mt-1_44.lib'];
# LIBS=vLibs,
env = Environment();

env.AppendUnique(CXXFLAGS=Split("/EHsc"));
env.Append(CPPPATH = ["C:\\Program Files (x86)\\boost\\boost_1_44"]);
env.Append(LIBPATH = ["C:\\Program Files (x86)\\boost\\boost_1_44\\lib"]);

env.Program( Glob('test.cpp'),LIBS=vLibs)

$ b b

我不断收到类似

I keep getting errors like

test.obj：error LNK2019：unresolved external symbolclass boost :: system :: error_category函数void __cdecl boost :: system ::`动态初始化器中引用的posix_category的引用的const& __cdecl boost :: system :: generic_category（void）（？generic_category @ system @ boost @@ YAAEBVerror_category @ （void）（?? __ Eposix_category @ system @ boost @@ YAXXZ）

如果我使用visual studio，

If I use visual studio, I get similar errors:

错误2错误LNK2001：未解析的外部符号boost :: system :: error_category const& __cdecl boost :: system :: generic_category （void）（？generic_category @ system @ boost @@ YAABVerror_category @ 12 @ XZ）T：\VS\temp\test.obj temp

Error 2 error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::generic_category(void)" (?generic_category@system@boost@@YAABVerror_category@12@XZ) T:\VS\temp\test.obj temp

直到我将库添加到项目，之后错误消失，它编译良好（在visual studio不SConstruct）。

Until I add the libraries to the project, after which the errors go away and it compiles fine (in visual studio not SConstruct).

我试过库的每个组合（共享/非共享/运行时共享/ runtime-unshared / debug），但我总是得到相同的错误。

I've tried every combination of the libraries (shared/unshared/runtime-shared/runtime-unshared/debug), but I always get the same errors.

我一直在寻找最近6小时内的答案，所以非常感谢您的帮助。

I've been searching for an answer for the last 6+ hours, so I'm grateful for any help.

注意：我没有使用自动链接（#define BOOST_ALL_NO_LIB），因为gcc不支持它）

NOTE: I'm not using autolinking (#define BOOST_ALL_NO_LIB) because gcc doesn't support it)

以下是Scons的输出：

Here's the output of Scons:
