mksm is a tool to generate SMLinux-compatible package build files. It currently
|
||||
supports generation of build files for sources that support compilation using:
|
||||
-> Make
|
||||
-> Autoconf
|
||||
-> Cmake
|
||||
-> Meson
|
||||
|
||||
Usage: mksm <application_name> <application_version> <build_system>
|
||||
|
||||
**You must be inside the directory containing source tarball when running mksm.**.
|
||||
For example if you want to build glib 2.60.0,
|
||||
|
||||
$ mkdir glib && cd glib
|
||||
$ wget <glib-source-tarball-URL>
|
||||
$ ls
|
||||
...
|
||||
glib-2.60.0.tar.xz
|
||||
...
|
||||
|
||||
$ mksm glib 2.60.0 meson
