Installation requires preinstalled proj4?

Hi,

I'm trying to properly install the Saga 2.0.7 binaries on my openSUSE 11.3
x86_64 machine. I have ensured that I have wxGTK, GDAL, GEOS, TIFF and Jasper
installed, and in the process have realized that I also need unixODBC,
PostgreSQL, as well as all the development packages for packages mentioned
earlier (for header files). I'm trying to install using

./configure --prefix=/usr/local/saga

make

and I get the following error:

PROJ4_Base.h:70:22: fatal error: projects.h: No such file or directory

compilation terminated.

Errors similar to this suggested that I needed developer versions of GDAL,
GEOS, etc, which fixed THOSE errors, but even after installing Proj.4 (can't
find libraries for it anywhere though) the error persists.

Any ideas? I didn't think that I'd have to install so many packages just to
get 'make' to work, and it feels like I'm going about this wrong. Any input
would be appreciated, and I'm happy to post output. Thank you!

hi,

there is a saga wiki page on how to compile saga on linux:
https://sourceforge.net/apps/trac/saga-gis/wiki/Compiling%20a%20Linux%20Unico
de%20version.

the dependencies are only listed for fedora and ubuntu, but i think the
package names should be very similar.

you need the both, the libraries and the developer packages containing the
header files to build saga. i don't think there is a dependency on postgres.

in your case the commmands would be:

autoreconf -i

./configure --enable-unicode

make

the default value for the prefix is already set to /usr/local, so you don't
have to specify it.

regards,

Hi there, thank you for your reply!

i followed those instructions, and after some tinkering, things went a little
better. I still didn't expect to have to install so many additional packages.

However. when I enter the 'make' command, after quite some time processing, I
get this output:

.......

/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/bin/ld:
cannot find -lpoppler

collect2: ld returned 1 exit status

make: *** Error 1

........

and the process is aborted. SO I don't know what -lpoppler is (presumably some
library I'm trying to link to that either doesn't exist or is in the wrong
path), but for now I'm hung up again. I was so close!

So does anyone know which library lpoppler would link to, so I can make sure
it's installed? Thank you again! (although don't let my cheery sounding
exclamation points mask the fact that I'm frustrated)

The error is issued from the SAGA GDAL Import/Export Grids module, but the
error message indicates that there is a problem with your GDAL installation.
As far as I know, libpoppler is used in GDAL with the Geospatial PDF driver
and that this driver is optional. Seems like the GDAL package you have
installed is build with GeoPDF support, but that you miss the complete
development package (or the package misses to include the dependency on
libpoppler). I would suggest to verify your GDAL install, libpoppler is no
dependency for SAGA.

Hi, thank you for the suggestion. I reinstalled GDAL using my package manager
and the problem was not fixed. I then installe dthe poppler development
package, and the error disappeared, but then another error popped up, cannot
find -lxerces-c, which I googled and then installed the xerces development
files. So THAT error went away, and the next error is cannot find -lopenjpeg,
so I installed THAT development package and now the error is cannot find
-lgif. So clearly I cannot continue this way, I shouldn't have to manually
install each one of these, to resolve a cascade of errors. I don't know how
many development packages I'm missing, but should these files be contained in
GDAL or something, and even though I reinstalled, the installation is still
not being recognized?

I know that I'll use SAGA in the future, I understand it's very powerful, but
all I wanted to do was read in some USGS .dem files and convert them to text!

I can understand that this is frustrating, but this has nothing to do with
SAGA itself but missing development packages on your system (most if not all
of them required by GDAL). Did you have a look at
http://sourceforge.net/apps/trac/saga-gis/wiki/Compiling%20a%20Linux%20Unicod
e%20version? There are all
dependencies listed that are necessary to build SAGA on Fedora and Ubuntu.
Maybe SUSE has some more.

I see two possibilities: search and install the missing libraries or disable
the build of the io_gdal module in case you don't need it. In order to disable
the module, you would have to edit the Makefile.am in /src/modules_io and
remove the "gdal" entry. Then rerun autoreconf and configure before building
again.

Thank you again, I know that this is an issue on my system, not with Saga,

Of the two options that you proposed (which make sense), I suppose I will
simply have to install each library as it appears. For my purposes now, I
understand that I need the GDAL module to import USGS .DEM raster files, so
it's important that the function is not disabled.

I'll let you know how it goes, and thank you!

Fantastic!

Actually there were only two more libraries I had to install before make
succeeded, make check, make install and make clean were then successful. When
I tried to run saga_gui, I was receiving an error about not finding
libsaga_odbc-2.0.7.so, even though it was clearly in the /usr/local/lib
directory, I had to add to my .bashrc file:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

or type it in the command line before executing saga_gui. But now things run
smoothly, and first crack importing my .DEM file as a raster worked well.
Thank you for your help!

For those of you who find your way here with a similar problem, I made sure
that I had all of the following DEVELOPMENT libraries installed:

jasper

geos

gdal

tiff

unixodbc

proj4

wxgtk

openjpeg

gif

xerces

poppler

mysqlclient

Nice to hear, maybe this list of dependencies should be added to the wiki
page. Instead of setting the library path variable you may try to run the
ldconfig command once.
