这真让我发疯。在我的CMakeLists.txt
中,我有:
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
并且:
$ 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).
我以前使用过自动编译的1.63.0
,但是已经删除了/usr/local/lib
和/usr/local/include
中的所有文件。也许还是在这里出没。
如果我发现这样的Boost(没有系统):
find_package(Boost 1.63.0 REQUIRED)
..然后配置成功,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
答案 0 :(得分:0)
问题是,即使使用system
时,它也会抱怨缺少SYSTEM
,但您应该要求boost_system
而不是SYSTEM
。我发现一个位令人困惑:
find_package(Boost 1.63.0 REQUIRED system)
