快把我逼疯了。在我的CMakeLists.txt
中有:
find_package(Boost 1.63.0 REQUIRED SYSTEM)
结果:
[0/1] Re-running CMake...
Build type: Release
CMake Error at /usr/share/cmake-3.10/Modules/FindBoost.cmake:1947 (message):
Unable to find the requested Boost libraries.
Boost version: 1.65.1
Boost include path: /usr/include
Could not find the following Boost libraries:
boost_system
但是:
$ locate libboost_system
/usr/lib/x86_64-linux-gnu/libboost_system.a
/usr/lib/x86_64-linux-gnu/libboost_system.so
/usr/lib/x86_64-linux-gnu/libboost_system.so.1.65.1
和:
$ sudo apt install libboost-all-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libboost-all-dev is already the newest version (1.65.1.0ubuntu1).
我以前使用过一个自编译的1.63.0
,但是我已经从/usr/local/lib
和/usr/local/include
中删除了所有的文件。也许它还在这里萦绕着..?
如果我发现这样的刺激(没有系统):
find_package(Boost 1.63.0 REQUIRED)
..then配置成功,但不会链接到${Boost_SYSTEM_LIBRARY}
/usr/bin/ld: src/app/CMakeFiles/app.dir/application.cpp.o: undefined reference to symbol '_ZN5boost6system15system_categoryEv'
//usr/lib/x86_64-linux-gnu/libboost_system.so.1.65.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

问题是,您应该要求system
而不是SYSTEM
,即使它在使用SYSTEM
时也抱怨缺少boost_system
。我发现位令人困惑:
find_package(Boost 1.63.0 REQUIRED system)
