Re: [tlug] Compile/load problem with graphics library

[Brian Chandler <brian@example.com>]

Thanks for the many responses. I was looking for people who know more 
than I do, so I don't mind the taunts - and anyway, the last time I was 
working on a real project in C++ was very nearly 30 years ago.

This program suddenly stopped working, I think when my site got 
transferred to a new host at pair.com. I had tried the very obvious 
things, like rm *.o to make sure all the object files were updated. And 
about the loader flags -- the most helpful answer I (just) found is here:

https://stackoverflow.com/questions/519342/what-is-the-difference-between-i-and-l-in-makefile

It says "Even if it may work otherwise, the -l... directives are 
supposed to go after the objects..."; this encourages me to think that I 
am not mad, and yes the makefile was working. But I am a reformed 
person, and will make a new makefile, with the loader flags separated 
from the libraries, and the flags before and the libraries after.

I am also using various image functions directly from PHP, but this is 
(simple) pixel twiddling, and I can't remember whether I couldn't find 
anything to access a single pixel value directly from php, or whether 
there was, but it took 100s of times too long (which is very plausible).

Anyway, I have somehow to get an Imagemagick library to link to this. 
More details in another post.
