Linux/PROCESSOR-SDK-AM335X: How to create ipk package

Hello Robert,

It is very easy to create ipk files with the OE build system. You just need to copy tnftpd_20130325.bb recipe to <tisdk>/sources/meta-openembedded/meta-networking/recipes-support/tnftp/ and tnftpd-autotools.patch within <tisdk>/sources/meta-openembedded/meta-networking/recipes-support/tnftp/tnftpd/ directory then run MACHINE=am335x-evm bitbake tnftpd -c do_package_write_ipk command.

Alternatively you can build ipk out of the three, manually by creating CONTROL and data directories with the populated content below.

<CONTROL>/control
Package: tnftpd
Version: 20130325-r0
Description: Enhanced NetBSD ftp server
 tnftpd (formerly known as lukemftpd) is a port of the NetBSD FTP server
 to other systems. It offers many enhancements over the traditional BSD
 FTP server, including command-line editing, command-line fetches of FTP
 and HTTP URLs (including via proxies), command-line uploads of FTP URLs,
 context-sensitive word completion, dynamic progress bar, IPv6 support,
 modification time preservation, paging of local and remote files, passive
 mode support (with fallback to active mode), SOCKS support, TIS FWTK
 gate-ftp server support, and transfer rate throttling.

<CONTROL>/postinst
#!/bin/sh
    update-alternatives --install /usr/bin/ftpd ftpd /usr/libexec/tnftpd 100

<CONTROL>/prerm
#!/bin/sh
    update-alternatives --install /usr/bin/ftpd ftpd /usr/libexec/tnftpd 100

Create a data directory with the tnftpd binary.
<data>/usr/libexec/tnftpd

Use opkg-build command to create an ipk.

Usage: ./opkg-build [-c] [-C] [-Z compressor] [-O] [-o owner] [-g group] <pkg_directory> [<destination_directory>]

If you do not have opkg-build in your computer, you can find one in <tisdk>/build/arago-tmp-external-linaro-toolchain/work/x86_64-linux/opkg-utils-native/<version>/image/<path-to-tisdk>/build/arago-tmp-external-linaro-toolchain/work/x86_64-linux/opkg-utils-native/<version>/recipe-sysroot-native/usr/bin/ directory.

To create an ipk in the target EVM board, you need to install the opkg-utils package from <tisdk>/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/opkg-utils/<version>/deploy-ipks/armv7ahf-neon/ to your EVM, native-compile the tnftpd and create the same CONTROL and data directories with the same populated content from above and use the same opkg-build command to create the ipk.

Best regards,
Kemal
