That's not true; it doesn't matter where you unzip Allegro. To
determine where it should install the library, header file and info
file it uses the DJDIR environment variable which (when running a
djgpp program) should always point to djgpp's directory, unless your
installation is broken. Note that DJDIR is set automatically -- you
don't need to set it yourself, and if you do then your setting will
just be ignored.
This could still be the reason why Vadim's Allegro didn't install
properly. Because Allegro works in this way, it won't be able to
install if you don't have write access to the drive where you
installed DJGPP. If it's a network drive you need to get your
administrator to install Allegro, or arrange a local djgpp directory
where you can install files just for yourself.
If you need to do this, create a local djgpp directory somewhere you
can write, with `include' and `lib' subdirectories. In your
environment set the following, if they are not already set:
CPLUS_INCLUDE_PATH=c:/locdjgpp/include
C_INCLUDE_PATH=c:/locdjgpp/include
LIBRARY_PATH=c:/locdjgpp/lib
INFOPATH=c:/locdjgpp/info
replacing "c:/locdjgpp" with the name of your local djgpp directory if
it's not "c:/locdjgpp".
If any of the above were already set then you should find out who set
them and why, before continuing.
Now the compiler should look in the named directories in addition to
looking in the standard ones. You need to arrange for your libraries
to install to the local directory tree. In Allegro's case you could
just make as usual, ignore the error message at the end, and copy the
files across by hand. Or you can change the following lines in the
makefile:
LIBDEST = $(DJDIR)/lib/liballeg.a
INCDEST = $(DJDIR)/include/allegro.h
DOCDEST = $(DJDIR)/info/allegro.inf
to this:
TARGET_DJDIR = $(DJDIR)
LIBDEST = $(TARGET_DJDIR)/lib/liballeg.a
INCDEST = $(TARGET_DJDIR)/include/allegro.h
DOCDEST = $(TARGET_DJDIR)/info/allegro.inf
Then the target will default to the real djgpp tree, but you can
override it like this:
make TARGET_DJDIR=c:/locdjgpp
replacing "c:/locdjgpp" with the real path of course.
Note that I've never done this over a proper network; however, I set
it up over a peer-to-peer network once, and it worked fine.
