[Gdal-dev] c# Bindings in Mono/Linux

Sat Jun 7 18:30:21 EDT 2008

Hi,

I`ve just tried http://download.osgeo.org/gdal/gdal-1.5.2.tar.gz on my
debian AMD64 installation following your compile steps (the install
directory was different). After the successful build I had managed to
run `make test` in the /csharp directory without further hackings and
file copies. (the csharp related files .so .dll .config was in the
same directory where the application has been started)

However my mono and SWIG version are different:

szekerest at sirius:~$ swig -version

SWIG Version 1.3.31

Compiled with g++ [x86_64-unknown-linux-gnu]
Please see http://www.swig.org for reporting bugs and further information
szekerest at sirius:~$ mcs --version
Mono C# compiler version 1.2.2.1
szekerest at sirius:~$ cat /proc/version
Linux version 2.6.18-5-amd64 (Debian 2.6.18.dfsg.1-13etch6)
(dannf at debian.org) (gcc version 4.1.2 20061115 (prerelease) (Debian
4.1.1-21)) #1 SMP Tue Dec 18 21:39:26 UTC 2007

FYI: The expected compile outputs and the `make test` results can be
inspected at the buildbot:

Best regards,

Tamas

>  - In addition copy *.dll, *.dll.config to $GDAL_HOME/bin
