C++ and web access

[outsider]

I done some programming in UNIX and I hope to port it over to Linux. What should I do? I am new to Linux. Need to use for programming and web access. What are the steps to d so? Does Knoppix comes with gcc, perl and web access(e.g. setup webserver)?

[fingers99]

Yes to all 3 :wink:

You might like to see if there's a compatable gcc on your *nix system. From (ancient) memory, it's nice to check that the code compiles on gcc on the original platform before trying to port it over -- it rules out compiler quirks.

On my *nix course I used to drive everyone nuts by insisting on using bash instead of ksh and gcc instead of whatever compiler HP-UX has as default.

So what are the steps to setup the web server? Does it have CGI?

[fingers99]

It's Apache. CGI is available (although very much out of fashion). Just get hold of the Apache documentation: it's all there.

Can anyone help me? I was trying to compile in Knoppix, but I got the following error. When I did it in Sun Solaris, it was ok. What is wrong?

Good Luck!

what are the changes that I need to make?
It can't seem to find hash_set which is a library file.

"stopword.h:6:20: hash_set: No such file or directory"

It could be one of several packages if you are installed to the HD then you should check to see if you have them installed, the search at http://packages.debian.org.

g++ requires

using namespace std;

are you including this line?

It still does not work even though I included "using namespace std;".

It still have the error "stopword.h:6:20: hash_set: No such file or directory"

[A. Jorge Garcia]

Maybe if you found the folder where that interface file resides you can add the -I option for g++ to find include files in other directories. For example, if stopword.h is in the folder /usr/bin/gcc and I needed it in my hello world program hello.cc the compile line would be something like:

g++ -o hello -I/usr/bin/gcc hello.cc
