【问题描述】:
这让我发疯了。在我的CMakeLists.txt 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
还有:
$ 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).
我之前使用过自编译的1.63.0,但是我已经删除了/usr/local/lib和/usr/local/include中的所有文件。也许它仍然以某种方式困扰着这里..?
如果我发现像这样的 Boost(无系统):
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
