All,

I wish to have string (combination of string value and int value) which increments until 100. The code is as below -

--- #include <iostream> #include <cstdlib> #include <string> #include

using namespace std;

int main() {

std::string TID = "Apple"; int TagID = 01, Value = 000 /* 100 IDs*/; std::string TagName, TagInitial, TagUId; TagName = TID + boost::lexical_caststd::string(TagID); //

Should

...

be as -> Apple01

TagInitial = TagName + boost::lexical_caststd::string(Value);

//

...

Should be as -> Apple01000

int i = boost::lexical_cast<int>(TagInitial) + 1; // Should be as

-> Apple01001

TagUId = boost::lexical_caststd::string(i); std::cout << "Tag ID .." << TagUId << endl;

}

I get below error message -

-- terminate called after throwing an instance of

'boost::exception_detail::clone_impl

...

ectorboost::bad_lexical_cast

...

'

what(): bad lexical cast: source type value could not be interpreted

as

...

target Aborted (core dumped) --

Any clue?

Apple01000 cannot be interpreted as an integer, that's why boost::lexical_cast<int>(TagInitial) throws.

I don't think so.

It compiled successfully ( $ g++ test.cpp -o test -lboost_system -lboost_thread ) with GCC-Boost v-1.54 but while linking and execution it gives error as shared.

I think if I can know - How to support lexical or what is the build command to support lexical analysis of Boost during Boost-v1.54 build process with toolset of gcc? I do see lexical_cast.hpp file in include file of Boost-v1.54 while building.

I don't understand. You get a run time exception. You do know that lexical_cast operates at run time, don't you? PS: Don't top post, please.
