## NAME
       dpkg-build-api - source package dpkg build API level

## SYNOPSIS
        Build-Depends:
         dpkg-build-api (= 1),

## DESCRIPTION
       The source package dpkg build API level, defines a versioned interface for source packages,
       where each API level provides specific behaviors and guarantees.

       These interfaces can then be adopted by packages in a gradual way, and phased out more easily
       than with global behavior changes.

       The declaration of this API level is done through build-dependencies, in one of **Build-**
       **Depends**, **Build-Depends-Indep **or **Build-Depends-Arch**, or via the environment variable
       **DPKG_BUILD_API**, which will override these if both are present, and might emit a warning in
       case they are different.

## API LEVELS
       v2  This level is still under development, and cannot be declared via build-dependencies.

       v1  This is the recommended level.  Since dpkg 1.22.0.

           Changes from v0 are:

           •   **dpkg-shlibdeps  **no  longer  uses  the  **LD_LIBRARY_PATH  **environment variable.  The **-l**
               option should be used instead.

           •   **dpkg-buildpackage **defaults to  **Rules-Requires-Root  **value  **no**.   To  restore  the  **v0**
               behavior **Rules-Requires-Root **should be set to **binary-targets**.

           •   **dpkg-buildpackage  **expects  all  required _debian/rules_ targets to be supported and no
               longer has backwards compatibility fallback code.  The required  targets  are  **clean**,
               **build**, **build-indep**, **build-arch**, **binary-indep **and **binary-arch**.

           •   **vendor.mk     **defaults     to     using     **dpkg_vendor_derives_from_v1    **for    the
               **dpkg_vendor_derives_from    **macro.     To    restore    the    **v0    **behavior     set
               **dpkg_vendor_derives_from **to **dpkg_vendor_derives_from_v0**.

           •   **default.mk **defaults to including **buildtools.mk**.

       v0  This  is  the current global level, equivalent to not specifying one.  The interfaces and
           behaviors provided are subject to the normal global  interface  updates,  which  tend  to
           require longer deprecation cycles and/or coordinated transitions.
