Why won't this simple Boost string example compile?

[Saqib Ali]

I'm using Solaris 10. And I'm trying to compile the simple Boost
string program shown at the top of this link:

http://www.boost.org/doc/libs/1_47_0/doc/html/string_algo/usage.html#id2895475

Here is my compile line: /opt/solstudio12.2/bin/CC -c myTest.C -I /
BOOST/include -o myTest.o

But compilation fails and I can't figure out why. Here are the error
messages:

"myTest.C", line 43: Error: Cannot use std::string to initialize int.
"myTest.C", line 44: Error: Cannot use std::string to initialize int.


FYI, line 43 & 44 are

to_upper(str1); // Line 43
trim(str1); // Line 44

Can anyone advise how to fix?

That simple example does not have 44 lines of code. Your problem lies
in the code that you have not told us about.

Ok. I guess that is a fair point. I had some white-space at the top of
the file. Now I have removed it so it is identical to what is shown at
the link I provided. Here is the error I'm getting:


"myTest.C", line 8: Error: Cannot use std::string to initialize int.
"myTest.C", line 9: Error: Cannot use std::string to initialize int.

Ok. Fair point I guess. I had a lot of white-space at the top of my
file. I have now removed it so that it is exactly identical to the
snippet found at the link I posted above. But I am getting the same
error:

"myTest.C", line 8: Error: Cannot use std::string to initialize int.
"myTest.C", line 9: Error: Cannot use std::string to initialize int.

You need your function calls (i.e. to_upper(str1); trim(str1); ) to
be either in some scope where such statements are valid - i.e. in a
function scope such as main(), or initialising a file-scope/global-
scope variable. What does the following say:

#include <boost/algorithm/string.hpp>
using namespace std;
using namespace boost;

int main(void)
{
string str1(" hello world! ");
to_upper(str1); // str1 == " HELLO WORLD! "
trim(str1); // str1 == "HELLO WORLD!"

string str2=
to_lower_copy(
ireplace_first_copy(
str1,"hello","goodbye")); // str2 == "goodbye world!"
return(EXIT_SUCCESS)'
}

Same Error:

It may be a SunStudio related issue.
Try the same with gcc.

It may be a SunStudio related issue.
Try the same with gcc.

Interestingly, with gcc, compilation works:

gcc -c myTest.C -I BOOST/include -o myTest.o

But linking fails:

gcc myTest.C -I BOOST/include -L BOOST/lib -lboost_thread_d -
lboost_system_d -o myTest
