C/C++ FastCGI Developers toolkit example program (not working?) - c++

Question

I am using the fastcgi C/C++ toolkit, to develop a test fastcgi app.
I built (and am now testing) this example provided by the toolkit.
I have loaded Apache mod_fcgid and successfully restarted the apache2 daemon. However, when I try to access the fastcgi resource, it is returning a blank page.
Note: I made the following changes to the example code (as it didn't work with the default socket fd value of 0):
int sock_fd = FCGX_OpenSocket(":5000", 1);
FCGX_InitRequest(&request, sock_fd, 0);
My /etc/apache2/mods-enabled/fcgid.conf file looks like this:
<IfModule mod_fcgid.c>
AddHandler fcgid-script .fcgi
SocketPath /var/lib/apache2/fcgid/sock
IPCConnectTimeout 10
IPCCommTimeout 20
OutputBufferSize 0
MaxRequestsPerProcess 500
</IfModule>
My /etc/apache2/mods-enabled/fcgid.load file looks like this:
LoadModule fcgid_module /my/path/here/libs/mod_fcgid.so
I then accessed the 'resource' in a browser using the following url:
http://127.0.0.1:5000
What am I doing wrong? (assuming that someone has actually managed to get the example cited above, to work)
I am developing/testing on Linux Ubuntu 10.x

Answer 1

i don't use apache for while, but i think your url is bad
i assume your apache run on port 80 and your echo.fcgi is at root of apache folder
for information, i use nginx for serve fcgi application
http://localhost/echo.fcgi

Answer 2

Run apachctl -D to verify your have mod_fcgid running. I believe no output (i.e a white page) occurs when your process crashes.
You will need to compile your program with debugging (-O0 -ggdb), redeploy, and restart Apache.
Change your Apache config to only spawn one process. This will allow you to attach gdb to your FCGI application and debug it.
Let me know if you need further assistance.
