Problem with boost : ‘timer’ is not a member of ‘boost’ - c++

Question

I am trying to install a package called Siconos, which uses python and its libraries, and also C++ and other libraries such as oce and occ.
It is installed correctly but when I run a C++ code using Siconos it is giving me the follwoing Boost error,

Any suggestions ?

Answer 1

It's most likely missing the necessary #include file.
Boost files and others may include other files, but are unspecified as to what else they include (commonly referred to as "dragging in"). This means that if you forget to #include something, it might work anyway because it was nested inside another header. But after an update, or under a different configuration, that no longer works because the internal include files have changed.
You should check the Boost docs for the correct include file for that symbol, and add it to the top of whichever file contains the error. This may be necessary for several files.
