I don't use an IDE, or indeed any custom authoring tools for that matter. I write web pages in emacs, as plain HTML.
Si I was glad to find out that I'm not entirely alone. Bill Rushmore just wrote about Emacs as a Java IDE. Spurred on by this, I thought about upgrading the version of emacs that I use.
I've been stuck on GNU emacs, version 19, for a very long time. The reason I haven't upgraded to later version is that they're too darn slow. (The same goes for XEmacs.) Which is one reason for not using an IDE - an editor has to start faster than I can start typing.
I now have a dual Opteron desktop, so it should be possible to get the latest version to start up fast enough, right?
I don't know, the darn thing won't build.
So I download emacs, unpack it on my Solaris box, see what configure options I have, and type:
./configure --prefix=/usr/local/versions/emacs-21.4 --without-gcc
--with-xpm --with-jpeg --with-tiff --with-gif --with-png
Why without-gcc? I need this to go real fast, so I want to use the latest studio compiler and crank it up.
It fails. No xpm, png, in fact no nothing.
configure:2694: /usr/ccs/lib/cpp conftest.c >/dev/null 2>conftest.out
"/usr/include/sys/isa_defs.h", line 500: undefined control
Well, there's a fundamental problem. The configure script is trying to be too clever by half, and is calling cpp directly. Don't do that. Run it the same way the compiler does, and things will work much better.
So I tell it to use "cc -E". This gets it past some of the cpp stuff, but there are two new problems that crop up:
configure:5430: cc -o conftest -I/usr/openwin/include - g - O
-I/usr/openwin/include -L/usr/openwin/lib conftest.c -lpng -lz -lm
- lX11 - lkvm - lelf - lsocket - lnsl - lkstat 1>&5
ld: fatal: file g: open failed: No such file or directory
ld: fatal: file O: open failed: No such file or directory
ld: fatal: file lX11: open failed: No such file or directory
ld: fatal: file lkvm: open failed: No such file or directory
ld: fatal: file lelf: open failed: No such file or directory
ld: fatal: file lsocket: open failed: No such file or directory
ld: fatal: file lnsl: open failed: No such file or directory
ld: fatal: file lkstat: open failed: No such file or directory
There's a major thing wrong here. Why has it randomly decided to put spaces in? (And why does it think it needs libelf, libkvm, and libkstat just to see if it can find a png function? I'll let it off some of the other libraries, as although it doesn't need to specify them all there were times in the past when you had to.)
That's not all:
"junk.c", line 586: invalid input token: 8.elc
So it looks like it's trying to use the C preprocessor in different ways.
Really, I can't see why anyone would think that getting a configure script to make a bunch of random guesses (and often get them wrong) is anything other than a stupid idea. There was a time when unix variants differed dramatically and you needed a way to tell them apart, but that time has long gone. As it is, we've now got to the point where the amount of software that compiles and works is heading towards zero, and the worst thing is that - unlike in the old days when it would have taken a couple of seconds to fix the Makefile to make it work - actually correcting the error when it goofs up like this is almost impossible.
