boost的问题：‘；定时器&x2019；不是‘；boost’； 我试图安装一个称为SCONOS的包，它使用Python及其库，以及C++和其他库，如奥西和OCC。 它安装正确，但是当我使用SCONOS运行C++代码时，它给了我一个模糊的提升错误， |===========================================================| | Siconos software, version 4.4.0 - Copyright 2021 INRIA | | | | Free software under Apache 2.0 License. | |===========================================================| [ Generate CMakeLists.txt file in /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/.siconos ] [------------------- Configure project (cmake) --------------------] -- Boost version: 1.65.1 -- Configuring done -- Generating done -- Build files have been written to: /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/.siconos [---------------------- Build project (make) ----------------------] [ 33%] Built target BallPlugin Scanning dependencies of target BouncingBallTS [ 50%] Building CXX object CMakeFiles/BouncingBallTS.dir/scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp.o /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp: In function ‘int main(int, char**)’: /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp:147:12: error: ‘progress_display’ is not a member of ‘boost’ boost::progress_display show_progress(N); ^~~~~~~~~~~~~~~~ /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp:149:12: error: ‘timer’ is not a member of ‘boost’ boost::timer time; ^~~~~ /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp:150:10: error: request for member ‘restart’ in ‘time’, which is of non-class type ‘time_t(time_t*) noexcept {aka long int(long int*) noexcept}’ time.restart(); ^~~~~~~ /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp:162:9: error: ‘show_progress’ was not declared in this scope ++show_progress; ^~~~~~~~~~~~~ /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp:167:41: error: request for member ‘elapsed’ in ‘time’, which is of non-class type ‘time_t(time_t*) noexcept {aka long int(long int*) noexcept}’ cout << "Computation Time " << time.elapsed() << endl; ^~~~~~~ /scratch/rsayoud/Documents/siconos-tutorials/examples/mechanics/BouncingBall/BouncingBallTS.cpp:180:10: error: ‘SiconosException’ does not name a type; did you mean ‘SiconosVector’?

很可能缺少必要的

#include

文件。 Boost文件和其他文件可能包括其他文件，但未指定它们还包括哪些文件（通常称为“拖入”）。这意味着，如果您忘记包含某个内容，它可能仍然有效，因为它嵌套在另一个标题中。但在更新后，或在不同的配置下，由于内部包含文件已更改，因此不再工作

---

您应该检查该符号的正确包含文件，并将其添加到包含错误的任何文件的顶部。这对于几个文件可能是必需的。

可能代码

/scratch/rsayoud/Documents/siconos教程/示例/力学/BouncingBall/BouncingBallTS.cpp

缺少一个include。
