Compile PostGIS 2.0 (SVN)

[JP Glutting]

Thanks Ryan,

I deleted the source directory for postgis 2.0 SVN, started a new shell and
unzipped it, so start over clean. Then I set the environmental variables:

*export CPPFLAGS=-I/opt/local/include
export LDFLAGS=-L/opt/local/lib
export CPATH=/opt/local/include
export LIBRARY_PATH=/opt/local/lib
export CFLAGS="-arch i386 -arch x86_64"
export LDFLAGS="-L/opt/local/lib -arch i386 -arch x86_64" *
*export CC=/opt/local/bin/gcc-4.3
export CXX=/opt/local/bin/g++-4.3
*
and ran

*./configure --with-raster*

But it fails pretty quickly:

*checking build system type... i686-apple-darwin11.1.0*
*checking host system type... i686-apple-darwin11.1.0*
*checking for gcc... /opt/local/bin/gcc-4.3*
*checking for C compiler default output file name... configure: error: C
compiler cannot create executables*
*See `config.log' for more details.*

(I didn't have gcc43 installed, but it even fails on the binary I have in
that directory: gcc-mp-4.4)

However, after taking the the GCC and GXX declarations out, I got an error
from GDAL, and it turned out that GDAL hadn't built properly +universal, so
I rebuilt it and PostGIS compiled correctly.

I'm glad it is finally working. Thanks for all the information, Ryan. I hope
this thread is useful to someone else trying to compile the SVN version of
PostGIS using Macports dependencies.

Cheers,
JP
