Compile errors including boost/regex.hpp
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 When I try to compile a file that includes <boost/regex.hpp> I get the following error: # /home/me/Projects/myproject> make # /usr/bin/make all-am # make[1]: Entering directory `/home/me/Projects/myproject' # compiling main.cpp (g++) # In file included from /usr/local/include/boost/regex/regex_traits.hpp:27:0, # from /usr/local/include/boost/regex/v4/regex.hpp:39, # from /usr/local/include/boost/regex.hpp:31, # [ ... more traceback ... ] # # /usr/local/include/boost/regex/v4/regex_traits.hpp:87:1: error: macro "test" passed 2 arguments, but # takes just 1 # In file included from /usr/local/include/boost/regex/v4/regex.hpp:79:0, # from /usr/local/include/boost/regex.hpp:31, # [ ... more traceback ... ] # # /usr/local/include/boost/regex/v4/regex_format.hpp:849:1: error: macro "test" passed 2 arguments, but # takes just 1 # In file included from /usr/local/include/boost/regex/regex_traits.hpp:27:0, # from /usr/local/include/boost/regex/v4/regex.hpp:39, # from /usr/local/include/boost/regex.hpp:31, # [ ... more traceback ... ] # # /usr/local/include/boost/regex/v4/regex_traits.hpp:87:1: error: template declaration of ‘char (& # boost::re_detail::test)[2]’ # /usr/local/include/boost/regex/v4/regex_traits.hpp:87:1: error: expected unqualified-id before ‘...’ # token # /usr/local/include/boost/regex/v4/regex_traits.hpp:87:1: error: expected ‘)’ before ‘...’ token # /usr/local/include/boost/regex/v4/regex_traits.hpp:87:1: error: expected ‘)’ before ‘...’ token # /usr/local/include/boost/regex/v4/regex_traits.hpp:87:1: error: expected unqualified-id before ‘(’ # token # In file included from /usr/local/include/boost/regex/v4/regex.hpp:79:0, # from /usr/local/include/boost/regex.hpp:31, # [ ... more traceback ... ] # # /usr/local/include/boost/regex/v4/regex_format.hpp:849:1: error: template declaration of ‘char (& # boost::re_detail::test)[2]’ # /usr/local/include/boost/regex/v4/regex_format.hpp:849:1: error: expected unqualified-id before ‘...’ # token # /usr/local/include/boost/regex/v4/regex_format.hpp:849:1: error: expected ‘)’ before ‘...’ token # /usr/local/include/boost/regex/v4/regex_format.hpp:849:1: error: expected ‘)’ before ‘...’ token # /usr/local/include/boost/regex/v4/regex_format.hpp:849:1: error: expected unqualified-id before ‘(’ # token # make[1]: *** [myproject-main.o] Error 1 # make[1]: Leaving directory `/home/me/Projects/myproject' # make: *** [all] Error 2 # *** Failure: Exit code 2 *** This is how I'm compiling: # g++ -DHAVE_CONFIG_H -I. `mysql_config --include` `mysql_config --cflags` -std=c++0x -g -O2 -MT # myproject-main.o -MD -MP -MF .deps/myproject-main.Tpo -c -o myproject-main.o `test -f 'src/main.cpp' # || echo './'`src/main.cpp Basically, the compile errors trace back to when I include boost/regex.hpp: | #include <boost/regex.hpp> Any ideas why this occurs? Maybe it's because I'm not including -lbooost_regex as a compile option? I specified it as my "myproject_LDADD" macro in Makefile.am so I assume g++ knows when to use it. Thanks.

I did #include <boost/regex.hpp> as the first include statement. I'm the only one writing this program. I haven't defined a macro "test" anywhere. I even grepped for 'test' and found it only used as the BASH command "test" in configure and Makefile files (automatically generated from autotools).

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Okay, who's the smart one? I was also using mysql and so I was including my_global.h (something I heard you are supposed to include with the mysql libraries). Once I removed the culprit it compiled just fine. John Maddock:

That's kind of insane. On my copy of 1_53_0, that section of boost/regex/v4/regex_traits.hpp are: 85 namespace re_detail{ 86 #if !defined(BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION) && !BOOST_WORKAROUND(__HP_aCC, < 60000) 87 BOOST_MPL_HAS_XXX_TRAIT_DEF(boost_extensions_tag) 88 #else 89 template<class T> 90 struct has_boost_extensions_tag 91 { 92 BOOST_STATIC_CONSTANT(bool, value = false); 93 }; 94 #endif
That's hard to read. Is this the same command? g++ -DHAVE_CONFIG_H -I. \ `mysql_config --include` `mysql_config --cflags` \ -std=c++0x -g -O2 \ -MT myproject-main.o -MD -MP -MF .deps/myproject-main.Tpo \ -c -o myproject-main.o \ `test -f 'src/main.cpp' || echo './'`src/main.cpp If so, you should look at the preprocessed output (although you'll likely still get warnings). You can also get the list of where all the macros are defined. Something like this: g++ -DHAVE_CONFIG_H -I. \ `mysql_config --include` `mysql_config --cflags` \ -std=c++0x -g -O2 \ -MT myproject-main.o -MD -MP -MF .deps/myproject-main.Tpo \ -dD -E -o myproject-main.i \ `test -f 'src/main.cpp' || echo './'`src/main.cpp (Note changes: "-c" to "-dD -E", and ".o" to ".i" output). Now you can look through "myproject-main.i" and see if some header is defining "test" or not. If that didn't work, a few more questions: 1. What OS and compiler, and what versions of each? 2. Is this a proper install of boost (through bootstrap etc), or did you just copy the header files in? 3. Can you get a small, self-contained example to compile successfully? (e.g., no libtool noise) Good luck! Best regards, Anthony Foiani
