How to use 'apt' to get source code and then do separate compile [duplicate]

For this example I'll use icedtea-6-jre-jamvm as the package you want to rebuild.

First install all the dependencies and build essential:

sudo apt-get build-dep icedtea-6-jre-jamvm
sudo apt-get install build-essential

Then grab the source:

apt-get source icedtea-6-jre-jamvm

Then cd in the openjdk directory directory and build the deb, the -us and -uc here skip the GPG checks if you're just rebuilding it for yourself:

cd openjdk-6-6b24-1.11.5
dpkg-buildpackage -us -uc

Then go up a directory and you should have .deb files.

Sources:

• http://www.debian.org/doc/manuals/maint-guide/build.en.html

to just compile the package use the debian/rules script which is provided in each debain package:

sudo apt-get build-dep <package>
apt-get source <package>
cd <package>_<version>
./debian/rules binary

this just does the configure and the compile part.

You can use the follwing :

apt-get source <package>

you need to make sure you install the build dependencies :

sudo apt-get build-dep <package> 

for more info run :

man apt-get

Alternative option :First you need to know the location of the package. then download the tar file using :

sudo wget <url>

You can then untar it and compile it using make

if your not sure about the specific command look inside of the folder, there should be a README file or INSTALL which will tell you the appropriate command .
