[gdal-dev] building gdal with python and libtool

[Kai Mühlbauer]

Hi all,

while trying to build gdal on linux (on CircleCi in a CentOS based 
docker image using conda/conda-forge) like this:

------------------------------------------------------------
export CC=gcc
export CXX=g++
export CFLAGS="${CFLAGS}"
export CXXFLAGS="${CXXFLAGS} -DBOOST_MATH_DISABLE_FLOAT128"
export LDFLAGS="${LDFLAGS}"
export LINKFLAGS="${LDFLAGS}"
export CFLAGS="${CFLAGS} -m${ARCH}"
export CXXFLAGS="${CXXFLAGS} -m${ARCH}"

export LDFLAGS="$LDFLAGS -L$PREFIX/lib"
export CPPFLAGS="$CPPFLAGS -I$PREFIX/include"

./configure --prefix=$PREFIX \
             --with-hdf4=$PREFIX \
             --with-hdf5=$PREFIX \
             --with-xerces=$PREFIX \
             --with-netcdf=$PREFIX \
             --with-geos=$PREFIX/bin/geos-config \
             --with-kea=$PREFIX/bin/kea-config \
             --with-static-proj4=$PREFIX \
             --with-libz=$PREFIX \
             --with-png=$PREFIX \
             --with-jpeg=$PREFIX \
             --with-libjson-c=$PREFIX \
             --with-expat=$PREFIX \
             --with-freexl=$PREFIX \
             --with-libtiff=$PREFIX \
             --with-xml2=$PREFIX \
             --with-openjpeg=$PREFIX \
             --with-spatialite=$PREFIX \
             --with-pg=$PREFIX/bin/pg_config \
             --with-sqlite3=$PREFIX \
             --with-curl \
             --with-python \
             --disable-rpath

make
make install
-----------------------------------------------------------

we are experiencing the same issue like posted here:

http://www.michael-joost.de/gdal_install.html

Everything works OK, until the build descends into the swig/python 
subdir, then the two compile commands work using libtool. But when it 
comes to linking, we get this error:

/bin/bash -pthread -shared -L/home/sam/miniconda3/envs/_build/lib

Using internet search I found that it could be related to wrongly set 
environment variables. But I can't find any problems so far. Using 
configure with --without-libtool leads to stable build without errors.

Although we can build gdal this way, we like to find the root cause of 
this libtool-problem. Any hints appreciated!

Cheers,
Kai
