Hi all,
I'm trying to use r.area. For that I need to, of course, install it. As I've
never compiled and installed anything before, these questions might be kind
of stupid... So I apologize. Yes, I've read
My dad used to say The only stupid question is the one not asked.
http://grass.osgeo.org/wiki/Compile_and_Install#Compiled_C_modules
but although I tried what it asked me to do I didn't get the results I
expected. Here is what I tried on OpenSUSE 11.3, 32 bit:
First off, there's a module g.extension that is designed to make this
whole addon business smoother. I don't know about OpenSuse: You should
check first if it's available. If you have it, then just run:
g.extension r.area
and it does all the dirty work.
1. Went to the GRASS AddOns Wiki-page
(http://grass.osgeo.org/wiki/GRASS_AddOns) and tried to add the various the
SVN repository to my repository directories in Yast (the OpenSUSE system
tool). Didn't work, which I think is one of those things that everybody'll
say duh about, but when I say duh in this case, it comes from my heart
because I'm dumb :P
SVN is not a YAST repository. It's just way to maintain a collection of
source code. If you run the command that appears in the above wiki page,
you'll get on your computer the source code for all the addons. Then you
have to go into each subdir and compile the ones you want.
2. Found the source codes of r.area (consisting of description.html, main.c
and Makefile), copied their content into files with matching names in my
home directory
3. Followed the instructions on
http://grass.osgeo.org/wiki/Compile_and_Install to compile and install C
add-ons (under the assumption that that's correct for r.area - sure looks
like it is). Got the following results:
- Hoping that the add-on was a binary (I know, I know...), I tried compiling
it with
make MODULE_TOPDIR=/usr/bin/grass64/
Result:
Makefile:11: /usr/bin/grass64//include/Make/Module.make: Not a directory
make: *** No rule to make target
`/usr/bin/grass64//include/Make/Module.make'. Stop.
I think you have to be inside the directory where put the r.area source.
Okay. The computer spoke Latin to me. Noticing that it's got a path with two
slashes right after another after my input, I thought that perhaps it wasn't
finding the proper directory and tried it without the slash at the end:
make MODULE_TOPDIR=/usr/bin/grass64
Result:
Makefile:11: /usr/bin/grass64/include/Make/Module.make: Not a directory
make: *** No rule to make target
`/usr/bin/grass64/include/Make/Module.make'. Stop.
Alright. No more double slash, but for all intents and purposes the same
message. So I then tried setting up an alias, not because I understand what
that means but because it was also suggested on the page:
alias gmake64='make MODULE_TOPDIR=/usr/bin/grass64/'
Computer seemed to like this and gave no reply. However, the next line was
ready, so I guess the alias was set up. Then I tried installing it:
make MODULE_TOPDIR=/usr/bin/grass64/ install
Result:
Makefile:11: /usr/bin/grass64//include/Make/Module.make: Not a directory
make: *** No rule to make target
`/usr/bin/grass64//include/Make/Module.make'. Stop.
Obviously I'm doing something wrong. Thinking that I might be dealing with
source code that still needed to be prepared, I entered:
Yes, you need to have the whole GRASS source available for this. You go
into wherever you unpacked the source and there you run ./configure
Try to follow this wiki page:
http://grass.osgeo.org/wiki/Compile_and_Install#Addons
./configure
To which my computer replied:
bash: ./configure: No such file or directory
No luck. Can anybody help me? I know this is a relatively simple question,
but I don't seem to be able to make anything of the online help texts.
Thanks!!
Best,
Daniel
