[Cppcms-users] hello_world incorrectly working

From: Basile S. <ba...@st...> - 2012-12-08 11:23:36

Hello All,

I just discovered, downloaded and compiled cppcms-1.0.2

Linux/Debian/Sid/AMD64 GCC 4.7 
When running the hello_world example (in the examples/hello_world source directory
as ../../build/hello_world -c config.js

I am getting the following HTML page http://localhost:8080/hello

<html><body>
<h1>Hello World!</h1>

I don't understand. What is a problem?

Th produced HTML contains a lot of garbage and is not valid HTML.
[notice that there is no </body> in the output I have shown]
It is not the HTML code which the following routine should output
  void my_hello_world::main(std::string /*url*/)
  {
    response().out()<<
        "<html>\n"
        "<body>\n"
        "  <h1>Hello World</h1>\n"
        "</body>\n"
        "</html>\n";
  }

In other words, it seems that something is buggy in the example
(or probably in the cppcms library).

Can someone reproduce the bug?

Cheers

You are running invalid executable file, not one you build, but an internal test executable for CppCMS's build directory called hello_world.

Watch carefully what are you doing :-)

Then could you give step by step instructions on how to build a *working* hello world example???
(Why can't the one in the distributed tar ball be a valid example? Why distribute it in the first place??)


I just recompiled it, with the same buggy result

Thanks. That works but I still don't understand why my tentative gave garbage.

Because its other programm. Open cppcms-1.0.2/src/hello_world.cpp and you se.
Use examples/ and you can also look tests/
