NCSA Mosaic 2.7

NCSA Mosaic

This is NCSA Mosaic 2.7, one of the first graphical web browsers. If you're on Ubuntu or something like it, your time machine is fueled up and ready to go. Follow the instructions below to build and run.

Many thanks to Sean MacLennan and Alan Wylie for doing the heavy lifting. And, of course, hats off to Marc Andreessen, Eric Bina, and the rest of the NCSA team for kicking things off for us. Thanks!

Building

• First, install these packages:

  sudo apt-get install build-essential libmotif-dev libjpeg62-dev libpng12-dev x11proto-print-dev libxmu-headers libxpm-dev libxmu-dev
  

• Next, build with:

  make linux
  

• Run!

Libpng 1.4 compile problems

Patch to get mosaic compile against libpng 1.4

outdated build list?

I don't personally use Ubuntu (rather than UNIX/*BSD/etc., Slackware GNU/Linux) but you mentioned it, so I'm trying to build on family PC's Kubuntu-based GNU/Linux (KDE Neon, which is like Kubuntu 20.04 with newer KDE, no other changes. Of course Kubuntu itself is on to 22.04) It worked for a version in 2021 but now says the below.

Ubuntu 14.04 Build

Hi, I was able to compile it in Ubuntu 14.04 (Trusty Tahr) installing the following dependencies:

sudo apt-get install x11proto-core-dev libice-dev libpthread-stubs0-dev libsm-dev libxau-dev libxdmcp-dev x11proto-input-dev x11proto-kb-dev xtrans-dev libxcb1-dev libx11-dev libx11-doc libxt-dev libmotif-common libxm4 libmrm4 libuil4 uil libmotif-dev x11proto-xext-dev libxext-dev libxmu-headers libxmu-dev libpng12-dev libjpeg-turbo8-dev libjpeg8-dev libjpeg-dev libxpm-dev xorg-sgml-doctools

Hope it helps!

Mosaic Mac/Win Source

You wouldn't happen to have a copy of the Mac/Windows ports of Mosaic? The good people of NCSA don't seem to know where the code might be now... though I have it on good authority that the Win/Mac source were released briefly at one point, but I haven't seen it in the wild.

Probably won't compile with GCC 10 on Linux (`-fcommon` issue)

GCC 10 changed the default from -fcommon to -fno-common:

https://wiki.gentoo.org/wiki/Gcc_10_porting_notes/fno_common

I haven't tested this with your version of Mosaic, only with another fork (https://github.com/yotann/ncsa-mosaic -- because it has been ported to a newer version of libpng, see #8). IMO, it's more than likely that it affects your version as well (I don't see any relevant differences between the two) and wanted to let you know.

One blunt workaround is to add -fcommon:

diff --git a/makefiles/Makefile.linux b/makefiles/Makefile.linux
index 2cea009..ad03902 100755
--- a/makefiles/Makefile.linux
+++ b/makefiles/Makefile.linux
@@ -225,7 +225,7 @@ customflags =
 
 # ---------------------- END OF CUSTOMIZABLE OPTIONS -------------------------
 
-CFLAGS = -g $(sysconfigflags) $(prereleaseflags)
+CFLAGS = -fcommon -g $(sysconfigflags) $(prereleaseflags)
 
 # Don't worry about these -- for development purposes only.
 PURIFY = purify

As the Gentoo wiki points out, though, this is not an ideal solution. It also outlines nicely what should be done instead.

Additional packages needed to compile on Ubuntu

On a clean Ubuntu install, the following additional packages also need to be installed (together with the ones mentioned in the README: build-essential, libmotif3, libmotif-dev and libpng3)

• x11-proto-print-dev
• libxmu-headers
• libxpm-dev
• libxmu-dev

WTFont?

Built on Linux... just presents pages in fixed width, fixed height font. Ignores size changes for headings (i.e., <h1>) and any sort of text styles (i.e., <b>). I know these were supported at the time... but out of the box looks worse now on same pages than back in '93!

Changing fonts in the options menu does nothing... what am I missing?

(from another fork) .desktop file, libpng 1.5

The wtachi/ncsa-mosaic fork has a few changes such as libpng 1.5 compatibility and a .desktop file for various graphical environments. Maybe they should be pulled here.

patch for Makefile(s) to build on FreeBSD

This patch add Makefile.freebsd to build on freebsd, it only need to change 'X11R6' to 'local' and add a -D__bsdi__

The patch is here : http://rhaamo.gruik.at/patchs/ncsa-mosaic/0001-Add-makefiles-Makefile.freebsd-and-modifications-to-.patch
