See answer 2 in this post for a good and detailed explanation of the first error. Next: server.c:459:10: error: incompatible pointer to integer conversion initializing 'char' with an expres …

The staff's implementation does return /test/index.html. While your statement "However it does in fact call indexes() function to modify the URL, and redirect to index.html." is a reasonable human des …

You are never populating path2. That will cause the "test/index.html" fail. Look carefully at your strcat statements. Also, review the first 5 or so minutes of Week 2 lecture. You are not properly {} …

See the section on "interpret" (around page 8) of the instructions. Odds are you’re unfamiliar with popen. That function opens a "pipe" to a process (php-cgi in our case), which provides us with …

Oh, you elusive one! If line is "cat\n" then strlen(line) is 4. The individual chars are addressed at indexes 0 through 3. So this line if(line[len] == '\n') needs to be corrected to get the result yo …

If path is /home/ubuntu/pset6/public.... well, you see what's happening. Is it necessary to look at all the files in path to determine whether index.php|html exist? …

As you say, your curl request (properly) gives a 404 because you do not have a cat.exe file. There probably is a cat.exe file on the check50 server. You could copy cat.html to cat.exe. Then issue the …

This feedback \ expected an exit code of 0, not standard error of "======= Backtrace: =========\n==== indicates a seg fault. Try requesting cat.jpg in your browser and see if server bails with a seg f …

The problem starts here char* possible_query = strtok(NULL, "?");. In the case where request_line is "/hello.php?", strtok will return NULL, because the first call to strtok consumed all of request_li …

It appears this if(strncmp(httpVersion, "HTTP/1.1\r\n", strlen(httpVersion)) == 0) { is always false, based on check50 output. Since program is comparing httpVersion to a string literal, one can draw …

Try man 3 getopt. The salient info is int getopt(int argc, char * const argv[], const char *optstring); ... The getopt() function parses the command-line arguments. …
