Hi, I'm trying to do some tests of fpWeb on Windows Seven 64bits using Apache2 (32bits). The first test I did was compiling the HelloWorld sample from c:\lazarus\components\fpweb \demo\helloworld\cgi and trying to execute it, but it doesn't work (500 Internal server error).

This is what my Apache's logs in error.log file:

[Sat May 22 17:12:34 2010] [notice] Child 996: Child process is running [Sat May 22 17:12:34 2010] [notice] Child 996: Acquired the start mutex. [Sat May 22 17:12:34 2010] [notice] Child 996: Starting 64 worker threads. [Sat May 22 17:12:34 2010] [notice] Child 996: Starting thread to listen on port 8080.

Any hint?

Can you execute the module in a minimal test environment (not apache) ? (you need at least REQUEST_METHOD QUERY_STRING and PATH_INFO environment variables)

I have a test-cgi application ready, but still need to put it in Subversion. (it sets up a minimal CGI environment, and then executes the CGI application - easier to debug)

Hi Michael, thanks for replying.

I created a basic example called 'cgiproject1' consisting of only an TFPWebModule's OnRequest method like this, with no action:

procedure TFPWebModule1.DataModuleRequest(Sender: TObject; ARequest: TRequest;
AResponse: TResponse; var Handled: Boolean);
begin
??  AResponse.Content := 'Hello';
? Handled := True;
end;

Without environment vars, the result is this:

exception at 000000010003B5DC:
No REQUEST_METHOD passed from server.

If I set the environment var REQUEST_METHOD using "set REQUEST_METHOD=POST", or "GET", the result is this:

An unhandled exception occurred at $000000010001FC05 : EWriteError : Stream write error
$000000010001FC05
$0000000100034C77
$0000000100037D54
$0000000100033DCA
$00000001000015DE main, line 13 of giproject1.lpr

It doesn't matter if I set QUERY_STRING and PATH_INFO, the result is the same.

Make sure you compile for the right Apache version. In your FPC directory under /units/... there are 3 subdirectories

.../httpd13
.../httpd20
and
.../httpd22

Delete all but the version you have. For example, if you have Apache 2.2 then only leave the httpd22 directory there and delete the other two. This might not be the problem for CGI, but for Apache modules it was important when I played with it.

Should work, which version of fpc are you using? And you are really creating a cgi-app, not a f(ast)cgi one?

I'm using 2.5.1 from trunk, and yes, I'm creating a CGI Application. I'll come back to debugging this in a couple of weeks.

Thought so. Please try with fpc 2.4.0.

I'll try it. The root of my fault is that I thougth fpWeb was a Lazarus package, now I know it's an fcl one...
