Hello. Thank you for creating this project. Modula is a lot of fun.
Are there any classes in the libm3 library (or any other importable library) for socket programming? I see the m3-www folder of the repo, but *import("m3-www")* in the m3makefile and/or *IMPORT HTTP* in Main.m3 is not recognized and will not compile.
Directory m3-www is not a CM3 package. There are several immediately inside it that are
packages. (Evidence: they have a src subdirectory.) Of those, only m3-www/web
and m3-www/proxy are built in the CM3 installation. The one you want is m3-www/http.
So I was able to fix the failures you see by going into m3-www/http/src and issuing
first "cm3", then "cm3 -ship". This builds and installs the package http. Now I see
this in my install directory:
/usr/local/cm3$ find . -iname "*http*"
./lib/libhttp.a
./lib/libhttp.so
./lib/libhttp.so.5
./pkg/webcat/src/HTTPCat.m3
./pkg/http
./pkg/http/src/HTTPControlValue.i3
./pkg/http/src/HTTPControlValue.m3
./pkg/http/src/HTTPApp.m3
./pkg/http/src/HTTPPayment.i3
./pkg/http/src/HTTPPayment.m3
./pkg/http/src/HTTP.m3
./pkg/http/src/HTTPProxy.i3
./pkg/http/src/HTTPApp.i3
./pkg/http/src/HTTP.i3
./pkg/http/src/HTTPControl.i3
./pkg/http/src/HTTPProxy.m3
./pkg/http/src/HTTPControl.m3
./pkg/http/AMD64_LINUX/libhttp.a
./pkg/http/AMD64_LINUX/libhttp.so
./pkg/http/AMD64_LINUX/libhttp.m3x
./pkg/http/AMD64_LINUX/libhttp.so.5
./examples/httpd
./examples/httpd/src/HTTPD.m3
And this program compiles:
m3makefile:
import("http")
implementation("Main")
program("HTTPClient")
Main.m3:
MODULE Main
; IMPORT HTTP
; TYPE Style = HTTP . Style
; VAR V : Style
; BEGIN
END Main
.
Is the only solution for one to manually copy the relevant module and interface files into a solution and then import them as *MODULE("")* in the m3makefile?
Also, is there any example code anywhere which demonstrates basic networking functionality?
The build of http done, try looking at /usr/local/cm3/examples/httpd/src/

Couple things.
This is the contents of my usr/local/cm3/pkg. Not seeing m3-www there at all in fact. (My previous mention of seeing m3-www was in regards to the repo here on github) bitvector m3bundle m3quake patternmatching table-list
When I run cm3 in usr/local/cm3 I get the following: quake runtime error: unable to open "/usr/local/cm3/bin/config/AMD64_LINUX" for reading This is despite the fact that I have given all permissions to that folder. Tried deleting it and recreating it. Tried just deleting it. Am not too experienced with Linux so I may be missing something. Thank you for your help. |

in /usr/local/cm3 afterwards to see if the package http got installed.

I don't have m3-www/src anywhere on my system. That's what I was saying before. In fact, when I run find / -type d -name 'm3'* all I get are the following: /usr/local/cm3/pkg/m3objfile So no m3-www/src to run cm3 in. And even the folder were there, running cm3 results in the AMD64_LINUX folder mystery error I mentioned above. Is there anyway to include additional libraries (like http, tcp, etc.) as a pre-built importable package (like libm3) in future releases? |

Did you look at https://github.com/modula3/cm3/blob/master/m3-comm/tcp/src/common/TCP.i3 A nice example https://github.com/modula3/cm3/blob/master/m3-tools/m3browser/src/TCPServer.m3 |

Ah, you must not have pulled the git repo. That's where all the source code is,
which you need to compile something additional. /usr/local/cm3 is only compiled
stuff.
It's at https://github.com/modula3/cm3. When you get a local copy of that,
m3-www is directly inside it.

Yeah, I just followed the install instructions for the "Getting Started" part of Linux, missed that the repo needed to be cloned in order add libraries. Given the bizarre errors regarding AMD64_LINUX I'm now getting with any use of cm3 whatsoever, I'm now trying to start over with a Windows install. |
