Revision as of 08:40, 19 April 2009 by rosettacode>NevilleDNZ (routine 'http content' not available on win32)

I tested ALGOL 68 (I'm using release algol68g-mk16.win32), but it did not worked. Do I need a library? --Guga360 22:19, 18 April 2009 (UTC)

PS: I'm currently on Windows, i'll try to restart in Ubuntu later.


39 http content (reply, "", " /index.php?title=Special:Categories&limit=500", 0); 1 a68g16.exe: error: 1: tag "httpcontent" has not been declared properly (detected in c onditional-clause starting at "IF" in line 37).

I think it's really a library. But i never programmed in ALGOL, what should i do?

Hi Guya360,

This ALGOL 68 implementation is an interpretor, and it would require the library being linked into the a68g.exe binary. Hence the .exe you have definitely does not have "http content" linked in.

I ran it on Fedora9 OK. I just checked a68g-manual.pdf and it says:

Mark 8, July 2005

  1. Adds procedure http content for fetching web page contents (UNIX)
  2. Adds procedure tcp request for sending requests via TCP (UNIX)
  3. Adds procedure grep in string for matching regular expressions in a string (UNIX)

The key point being the (UNIX) at the end of the line. I am guessing that the tcp library for windows was enough different from the tcp library for Linux/Unix that the "http content" routine remains both un-ported and broken.

Now I have not tried Algol68g on Ubuntu. I hack around on Fedora. So you MAY be able to use the pre-compiled algol68g RPM for ubuntu (Does Ubuntu support RPMs?)

BUT the algol68g source tar ball will definitely work on ubuntu. (Maybe not on a 64bit Ubuntu as the libraries have moved to /lib64 - if so let me know and I'll sort/hack you up a 64bit update)

The compile should be as easy as installing gcc and configure (and if you need them then install postgres or curses or ... ) then:

tar -xvf /tmp/download/algol68g-mk16.tgz
./configure --threads
# as root
make install
# as user
a68g Sort_most_popular_programming_languages.a68

BTW: you are the first person to feed back on running the ALGOL 68 rosettacode code snippets... I am rather impressed. ThanX - (blush)

Is this snippet the first ALGOL 68 that you have tried?
