HOWTO build flex (libfl) for cris-axis crisv32-axis

Since some of the EPICS extensions and modules rely on libfl flex and the standard distribution of AXIS SDK doesn't contain the libfl.a this has to be added:

Prerequisites

• Axis SDK
• cross compiler

Build & Installation

1. set some helper variables:
   export SRC_DIR=<Source Directory>
export DOWNLOAD_DIR=<Download Directory>
# provided cross compiler and SDK are installed here export ETRAX_DIR=<ETRAX Tools Directory>
2. download sources from http://sourceforge.net/projects/flex/ (version 2.5.35) via direct link to $DOWNLOAD_DIR
   mkdir -p ${DOWNLOAD_DIR:?undefined} &&
wget http://prdownloads.sourceforge.net/flex/flex-2.5.35.tar.bz2?download
3. unpack to $SRC_DIR
   mkdir -p ${SRC_DIR:?undefined} &&
cd SRC_DIR &&
tar -jxvf flex-2.5.35.tar.bz
4. Source cris-axis-setup.sh ,defining environment variables, e.g. AXIS_TOP_DIR, and extending PATH, needs ETRAX_DIR to be defined.
   cd ${SRC_DIR:?undefined} &&
wget https://wiki.gsi.de/pub/Epics/EpicsTipsAndTricksCrisAxisAddtionForSeveralEpicsApplications/cris-axis-setup.sh &&
source cris-axis-setup.sh
   or just take its main code:
   oldpwd=$OLDPWD
base=$(pwd)
cd ${ETRAX_DIR:?undefined)/SDK && cd $(ls --color=never -t -1 -d devbo* | head -n 1) && . ./init_env
cd $base
cd ${ETRAX_DIR:?undefined)/ETRAX/compiler && . ./setup.sh
cd $oldpwd
cd $base
unset scriptname base oldpwd epicsDir
5. Change to source directory $SRC_DIR
   cd ${SRC_DIR:?undefined}
6. Since configure automatically sets for cross-compilers 'ac_cv_func_malloc_0_nonnull' and 'ac_cv_func_realloc_0_nonnull' to 'no', (since it cannot check it) those have to be configured by hand:
   1. cris-axis
      1. export myTARGET=cris-axis-linux-gnu
      2. make clean
      3. ./configure --prefix=${AXIS_TOP_DIR:?undefined}/target/${myTARGET:?defined}/usr --host=${myTARGET} --build=i686-pc-linux-gnu ac_cv_func_realloc_0_nonnull=yes ac_cv_func_malloc_0_nonnull=yes
      4. make
      5. make install
   2. crisv32-axis
      1. export myTARGET=crisv32-axis-linux-gnu
      2. make clean
      3. ./configure --prefix=${AXIS_TOP_DIR:?undefined}/target/${myTARGET:?defined}/usr --host=${myTARGET} --build=i686-pc-linux-gnu ac_cv_func_realloc_0_nonnull=yes ac_cv_func_malloc_0_nonnull=yes
      4. make
      5. make install
