Error building log4cxx with cmake and APR_STATIC option

[clobotorre]

Steps to reproduce:

# curl -L -O https://dlcdn.apache.org/logging/log4cxx/1.2.0/apache-log4cxx-1.2.0.tar.gz
# tar xzvf apache-log4cxx-1.2.0.tar.gz				
# apt-get install build-essential libapr1-dev libaprutil1-dev gzip zip
# cd apache-log4cxx-1.2.0
# mkdir build
# cd build
# cmake -DAPR_STATIC=yes ..
# make VERBOSE=1

The distro provided apr and apr-util static libraries are built without -fPIC (probably assuming everthing will be statically linked if anything is statically linked).

To build a log4cxx DSO with -DAPR_STATIC=yes you will need to also provide -DCMAKE_PREFIX_PATH=$HOME/libraries after populating $HOME/libraries with apr that you built yourself.

For example:

curl -L -O https://archive.apache.org/dist/apr/apr-1.7.4.tar.bz2
tar xf apr-1.7.4.tar.bz2
cd apr-1.7.4
export CFLAGS=-fPIC
./configure --prefix=$HOME/libraries
make install

I recommend you also use -DAPU_STATIC=yes when using -DAPR_STATIC=yes. This requires you build apr-util yourself as well.

curl -L -O https://archive.apache.org/dist/apr/apr-util-1.6.3.bz2
tar xf apr-util-1.6.3.bz2
cd apr-util-1.6.3
export CFLAGS=-fPIC
./configure --prefix=~/libraries --with-apr=$HOME/libraries
make install

Thank you so much. Solved!!
