Raising error, xtime.hpp compilation problem

Question

I am working on a C ++ project using Boost, and between compilers, I must have updated something in boost without meaning or something like that, because now Boost dependencies will not compile:

In file included from /usr/include/boost/thread/pthread/mutex.hpp:14:0, from /usr/include/boost/thread/mutex.hpp:16, from /usr/include/boost/thread/pthread/thread_data.hpp:12, from /usr/include/boost/thread/thread.hpp:17, from /usr/include/boost/thread.hpp:13, from /blah.h:4, from bluh.h:3, from bleh/main.cpp:4: /usr/include/boost/thread/xtime.hpp:23:5: error: expected identifier before numeric constant /usr/include/boost/thread/xtime.hpp:23:5: error: expected '}' before numeric constant /usr/include/boost/thread/xtime.hpp:23:5: error: expected unqualified-id before numeric constant /usr/include/boost/thread/xtime.hpp:46:14: error: expected type-specifier before 'system_time' In file included from /usr/include/boost/thread/pthread/mutex.hpp:14:0, from /usr/include/boost/thread/mutex.hpp:16, from /usr/include/boost/thread/pthread/thread_data.hpp:12, from /usr/include/boost/thread/thread.hpp:17, from /usr/include/boost/thread.hpp:13, from /blah, from /bleh,(changed these names, obviously) from /bluh /main.cpp:4: /usr/include/boost/thread/xtime.hpp: In function 'int xtime_get(xtime*, int)': /usr/include/boost/thread/xtime.hpp:73:40: error: 'get_system_time' was not declared in this scope /usr/include/boost/thread/xtime.hpp:73:40: note: suggested alternative: /usr/include/boost/thread/thread_time.hpp:19:24: note: 'boost::get_system_time' /usr/include/boost/thread/xtime.hpp: At global scope: /usr/include/boost/thread/xtime.hpp:88:1: error: expected declaration before '}' token make[2]: *** [CMakeFiles/edge_based_tracker.dir/main.o] Error 1 make[1]: *** [CMakeFiles/edge_based_tracker.dir/all] Error 2 make: *** [all] Error 2 

Any ideas? I tried changing TIME_UTC to TIME_UTC_, as it was recommended to me on another site, but that did not seem to help.

EDIT: Boost Version - Version: 1.48.0.2. I added xtime below:

EDIT. To make this clear, the code does not work when importing boost / thread.hpp

Answer 1

Since you are not showing your code, we can only guess. I assume that you are defining a TIME_UTC macro somewhere in your code. This macro header is messes-up xtime.hpp .

Answer 2

For those who are facing the same problem and trying to find a solution here. Obtained from the noodlebox link ( https://svn.boost.org/trac/boost/ticket/6940 ):

You can edit /usr/include/boost/thread/xtime.hpp (or wherever your xtime.hpp is located) and change all occurrences of TIME_UTC to TIME_UTC_ - perhaps around lines 23 and 71.

i.e. sed -i 's/TIME_UTC/TIME_UTC_/g'/usr/include/boost/thread/xtime.hpp

Answer 3

If you get syntax errors when using Boost, you may need to compile the code with -std=c++11 .

The TIME_UTC problem you may have read is a side effect of using C ++ 11. TIME_UTC now defined as a macro in C ++ 11, so you will either need to replace all TIME_UTC instances with TIME_UTC_ , or just use a newer one (1.50. 0+ ) version of Boost, where this has already been fixed.
