Boost non funziona più con Homebrew su Mac El Capitan

Question

Ho appena aggiornato da Yosemite a El Capitan e ha interrotto uno dei miei programmi C++ che faceva affidamento su Boost. Ogni volta che provo a compilare, ottengo questi errori:

fatal error: 'boost/timer/timer.hpp' file not found 
#include <boost/timer/timer.hpp> 

fatal error: 'boost/program_options.hpp' file not found 
#include "boost/program_options.hpp" 

ho compilarlo con le bandiere giuste e ha funzionato perfettamente prima:

-lboost_timer-mt \ 
-lboost_program_options-mt \ 

Ho seguito le istruzioni birra fatta in casa to chown/usr/local, esegui brew doctor e prepara l'aggiornamento, anche brew reinstall boost. Ho anche controllato e timer.hpp è presente in/usr/local/include/boost.

Aggiornamento Ran: clang ++ -E -x C++ - -v </dev/null

Answer 1

È necessario installare gli strumenti di riga di comando con Xcode xcode-select --install per ottenere una versione di clang che cerca/usr/local di default. Altrimenti, stai utilizzando le versioni fornite da Xcode, che cercano solo i percorsi dell'OS X SDK. (/ usr/bin/gcc e/usr/bin/g ++ entrambi invocano clang e non sono in realtà versioni di gcc.)

Answer 2

Ho avuto lo stesso problema quando ho aggiornato a El Capitan. Ho risolto questo problema reinstallando Boost con brew.

Se non si dispone di birra installato, è possibile installarlo con

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 

Quindi, installare spinta

brew install boost
