X11 Version Notes

To build the X11 version, run configure --enable-x11 and make. PDCurses will be built first in the lib/pdcurses subdirectory, and then Qodem will be built as qodem-x11.

Some known issues of the X11 build are:

Win32 Version Notes

To build the Win32 version, build each of the following projects in Visual C++:

Then rename the vc6qodem.exe produced to qodem.exe and use InnoSetup with the build/win32/qodem-isetup.iss script to create the final installer.

Some known issues of the Win32 build are:


Qodem relies on external code/libraries:

1.0.0 Development Snapshot

A work-in-progress 1.0.0 development source tarball is available here. The corresponding Windows installer is here.

New features in the development version include:

Building Qodem

Qodem uses GNU autoconf, but may have problems on some less-tested platforms (e.g. BSD, OSX). For those who wish to get a working binary, a much simpler makefile is provided in build/Makefile.generic. Execute make -f build/Makefile.generic clean qodem to build. CFLAGS and LDLIBS may need to be adjusted to suit.

General Comments

All features for the 1.0.0 release are now present, though some may have bugs.

This project was originally thought to only require 20,000-ish lines of code (measured with 'wc') to replicate the key features of Qmodem™. lrzsz was supposed to handle the file transfer protocols; command-line clients would handle the actual connections. Qodem would be more glue than anything else. However, each key feature turned out to be much more extensive: VT100 required a lot of testing; file transfer protocols had to be implemented inline to provide proper reporting and user control; eventual Win32 support required code to handle telnet/rlogin/etc.; host mode required server-side code for the protocols, and integrating with UPnP was an obvious needed feature; the list goes on. Today qodem exceeds 95,000 LOC but has only a few bugs to go. The point now of 1.0.0 is to finish the vision: go beyond feature parity with Qmodem™ and instead strive to be an excellent client for modern BBSes and other servers. See here for a more detailed discussion of the long slog to 1.0.0.
