Linux Build

FYI: Make sure bit architectures matches for all binary components; if you are using 64bit nodejs make sure you are using 64bit Informix Client-SDK as well.

FYI:

Prerequisite :

Update Packages

sudo apt-get update
sudo apt-get dist-upgrade

Install Node.js

# Remove old nodejs installation if any
sudo apt-get remove nodejs nodejs-legacy -y
sudo apt-get remove npm  -y

# Install nodejs
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs

FYI: Make sure you have the right version of node.js installed

rm /work/dev/nodejs
cd /work/dev

If 64bit Linux on x86

wget https://nodejs.org/dist/v10.16.3/node-v10.16.3-linux-x64.tar.xz
tar -xvf node-v10.16.3-linux-x64.tar.xz
sudo ln -s  /work/dev/node-v10.16.3-linux-x64  /work/dev/nodejs

If ARM v7 (Raspberry Pi 3)

sudo wget https://nodejs.org/dist/v10.16.3/node-v10.16.3-linux-armv7l.tar.xz
sudo tar -xvf node-v10.16.3-linux-armv7l.tar.xz
sudo ln -s  /work/dev/node-v10.16.3-linux-armv7l  /work/dev/nodejs

export PATH=/work/dev/nodejs/bin:$PATH
which node
node -v

Complile time environment

# sudo ln -s /opt/csdk450FC1 /work/csdk
# Assuming 'CSDK' is installed at /work/csdk
export CSDK_HOME=/work/csdk

Fire the build

cd /work/t1
git clone https://github.com/OpenInformix/IfxNode.git

cd /work/t1/IfxNode
npm update

rm -rf ./build
npm install -g node-gyp
# Raspberry Pi 3
# sudo npm install -g node-gyp

node-gyp configure -v
node-gyp build -v

check the build output, if all right then the driver binary is

ls -l ./build/Release/ifx_njs_bind.node

Quick test of the local build

Get a sample code
cd /work/try
rm -rf /work/try/node_modules
mkdir /work/try/node_modules

ln -s  /work/t1/IfxNode  /work/try/node_modules/ifxnjs
cp /work/t1/IfxNode/test/SampleApp1.js .
Set runtime environment to pick Informix Client SDK libraries.
export INFORMIXDIR=/work/csdk
export LD_LIBRARY_PATH=${INFORMIXDIR}/lib:${INFORMIXDIR}/lib/esql:${INFORMIXDIR}/lib/cli
# Set the INFORMIXSQLHOSTS too, say
# export INFORMIXSQLHOSTS=/work/dev/srv/ids0/sqlhosts
Run the sample
#cd /work/try
vi SampleApp1.js

# edit Connection Informaton and then run
node SampleApp1.js

Preparing it for prebuilt

Do this only if you plan to do a public release with the build binary.

# Build Cleanup
rm /work/t1/IfxNode/build/binding.Makefile
rm /work/t1/IfxNode/build/config.gypi
rm /work/t1/IfxNode/build/ifx_njs_bind.target.mk
rm /work/t1/IfxNode/build/Makefile
rm -rf /work/t1/IfxNode/build/Release/obj.target
rm -rf /work/t1/IfxNode/build/Release/.deps

# apt-get update
# apt-get install zip unzip

#### preparing it for prebuilt
cd /work/t1/IfxNode
zip -r build.zip ./build

# if Linu x64 then
mv build.zip ./prebuilt/Linux64/build.zip
md5sum       ./prebuilt/Linux64/build.zip

# ARM then only
# mv build.zip ./prebuilt/Arm/build.zip

# get the md5hash
md5sum    build.zip
# update prebuilt/README.md with the hash value.

# Check-in the changes.
