Question

我正在尝试使用Boost Libraries ......但无济于事。我尝试按照Boost网站上的入门教程（针对Unix变体），但在此过程中遇到了问题。

我将库编译到Downloads文件夹中的目录中：

/Users/myUsername/Downloads/boostCompiled

当我使用库的完整路径时...示例程序（在Boost网站上给出）编译并链接正常。

g++ -o boostTesting boostTesting.cpp -I /Users/myUsername/Downloads/boostCompiled/include/ /Users/myUsername/Downloads/boostCompiled/lib/libboost_regex.a

但是，当我尝试链接使用-L和-l选项时......它失败了......

g++ -o boostTesting boostTesting.cpp -I /Users/myUsername/Downloads/boostCompiled/include/ -L /Users/myUsername/Downloads/boostCompiled/lib/ -l boost_regex

ld: library not found for -lboost_regex
collect2: ld returned 1 exit status

g++ -o boostTesting boostTesting.cpp -I /Users/myUsername/Downloads/boostCompiled/include/ -L /Users/myUsername/Downloads/boostCompiled/lib/ -l libboost_regex

ld: library not found for -llibboost_regex
collect2: ld returned 1 exit status

g++ -o boostTesting boostTesting.cpp -I /Users/myUsername/Downloads/boostCompiled/include/ -L /Users/myUsername/Downloads/boostCompiled/lib/ -l regex

ld: library not found for -lregex
collect2: ld returned 1 exit status

我的shell是bash ...我已将DYLD_LIBRARY_PATH设置为以下内容：

export DYLD_LIBRARY_PATH=/usr/local/cuda/lib:/Users/myUsername/Downloads/boostCompiled/lib

看来我没有使用正确的名称链接（使用-l）选项。有人可以帮忙！提前谢谢！

Answer 1

-L与/Users/myUsername/Downloads/boostCompiled/lib/之间不应有空格
确保在libboost_regex.a中编译/Users/myUsername/Downloads/boostCompiled/lib。

然后这应该有效：

g++ -o boostTesting boostTesting.cpp -I/Users/myUsername/Downloads/boostCompiled/include/ -L/Users/myUsername/Downloads/boostCompiled/lib/ -lboost_regex

Boost Libraries：无法在MAC OS X上链接正则表达式库
