joyrock · 02-10-2010, 08:21 AM

I want to compile the the source code given in a well known unix programming book(stevens) .I downloaded the codes but unable to build it ,giving me an error
error: stropts.h: No such file or directory
I don't know what to do....
I am using fedora 11 latest gcc in the system.
I also try to include the search path which include a file -I./usr/include/xulrunner-sdk-1.9.1/system_wrappers but it does not help . I open the header file and the definition is there #include_next<strops.h>
so ultimately there is not the original file...
any one please help..

This one ? http://www.kohala.com/start/unpv12e.html
.. from 1998. Or this ? .. http://www.kohala.com/start/apue.html
.. 1992. Please specify book.

Twelwe year old code : some will compile OK, gcc-4.4.x
and some other will require fixing. ( Or gcc-2.95 ).

Please provide a link to the code, somebody may then
have an answer.

This error arises if your code does NOT define a main function as follows:

Code:

int main (int argc, char *argv[])
{
   // call your other functions
   return 0;
}

Alternatively, you could leave the parameters from main ...
