Re: [Boost-users] A linking error on switch_statement. Can anyone with kindness help me?

I am using Dev-C++ with boost 1.34.1,the program is the following: ....................... typedef std::map IIPrimemap; IIPrimemap primemapvec; # define BetaKGre2 1 # define EqualToOne 2 #define ProductOfKPrime 3 ......................... (switch_statement(_1, case_statement<BetaKGre2> (var(result)=0), case_statement<EqualToOne> (var(result)=1), case_statement<ProductOfKPrime> (var(result)=bind(static_cast(std::pow), constant(-1.0),bind(&IIPrimemap::size,var(primemapvec)))), default_statement ( var(result)=234) ))(switchvalue);

the complier told me no errors.But the linker told me that: nstantiated from `Arg::sig(std::pow), constant(-1.0),bind(&IIPrimemap::size,var(primemapvec)))), otherwise the program do not have such problems. How can I solve it?

1) This is a compiler error, not a linker error. The only way that you can get an error like this from the linker is if the linker is actually doing some of the work that would normally be done by the compiler. 2) It helps if you can provide minimal and complete code (i.e. something I can paste into a file and compile immediately) 3) Posting the noise in the compiler's error message while snipping the useful information is not helpful. 4) If I understand you correctly, this is an irreproducible environment problem, so there is basically nothing I can do to help.
