I think I'm going crazy. For some weird reason, I cannot get cmake to find boost_python. I've always used the same CMakeList and the same steps for installing Boost with Boost-Python support on macOS. On GNU/Linux and Windows I usually just build the library manually and it works just fine. Several months ago it also just worked perfectly fine on macOS by issuing the following commands:

brew install python2 boost boost-python

(I'm specifically using python2 and not python3)

I've no idea what's causing this issue because I've never had it before... perhaps it can't find the boost-python library from brew? (/usr/local/Cellar/boost-python/1.67.0/lib/). But then again, I never bothered with changing search paths for cmake or anything like that. This CMakeList always worked both under Linux and macOS.

my CMakeList.txt

  • Set Boost_DEBUG CMake variable to ON (e.g. via additional cmake command line option -DBoost_DEBUG=ON) and see which actual Boost files are searched and not found. Commented Jun 19, 2018 at 7:46
  • @Tsyvarev Thanks for the reply first! I ran the command and showed the output in my original post. The libraries should be found as "_boost_LIBRARY_SEARCH_DIRS_RELEASE = /usr/local/include/lib;" includes the correct search path "/usr/local/include/lib" in which all the boost libraries are located in (some are symlinks like libboost_python27-mt.a -> ../Cellar/boost-python/1.67.0/lib/libboost_python27-mt.a) Commented Jun 19, 2018 at 20:27
  • As you can see from debug output, name of the library file for search is boost_python-mt or so, it doesn't fit (after appending library prefix and suffix) to the file libboost_python27-mt.a which you have. Probably, you need to specify COMPONENTS as boost_python27. Commented Jun 19, 2018 at 20:34

@Tsyvarev this. I needed to change the COMPONENTS as "python27". This behavior definitely changed over the time. I don't remember having to do this at boost release >= 1.65 <= 1.67. Thanks.
