Cmake 包括柠檬图书馆
我只想将Lemon库添加到我的CMakeLists.txt中。当我不使用CMake时,我只是添加了“-lemon”,一切都很顺利,但现在我不知道将其添加到CMake文件的过程 已编辑的不包括myCMakeLists.txt:Cmake 包括柠檬图书馆,cmake,Cmake,我只想将Lemon库添加到我的CMakeLists.txt中。当我不使用CMake时,我只是添加了“-lemon”,一切都很顺利,但现在我不知道将其添加到CMake文件的过程 已编辑的不包括myCMakeLists.txt: # Created by the script cgal_create_cmake_script_with_options # This is the CMake script for compiling a set of CGAL applications. proje

它非常简单,请使用:
在本例中,我链接到libm。在您的情况下,m
将是lemon
。至少我认为,从你的问题来看,我不确定库名是lemon
还是emon
,因为-l
是标志,名称应该跟在后面(即-lm
links libm)
对于我的简单示例,如果我运行make VERBOSE=1
(并去掉不重要的行):
因此,它首先编译源文件,然后将
-lm
放在链接器行上。库的名称实际上是lemon
。但是当我运行make
命令时,现在我得到了错误clang:warning:-lemon:'linker'输入未使用,当'-c'存在时
@MauricioZambon因为它只是一个警告,所以生成的可执行文件仍然有效吗?不,它没有链接库。make VERBOSE=1
为生成警告的编译行显示了什么?/usr/bin/c++-DCGAL\u USE\u MPFR-DCGAL\u USE\u GMP-lemon-O3-DNDEBUG-I/opt/local/include-I/Users/../code-o CMakeFiles/ssp.dir/scheduleGraph.cpp.o-c/Users/../code/scheduleGraph.cpp
