Dear All, |
| 2 |
|
| 3 |
Gentoo on Android is about running Gentoo natively in a directory prefix |
| 4 |
on Android devices[1,2] in parallel with native Android, mentored by |
| 5 |
Luca. |
| 6 |
|
| 7 |
State, finished up to three wiki pages (on sdcard for gentoo partitiion, |
| 8 |
how to use the bootstrap script and how to cross compile out the |
| 9 |
toolchain toolchain). One quick report here, final report on the entire |
| 10 |
SOC follows. |

It turns out to be as easy as |
| 29 |
|
| 30 |
$ cat setcap |
| 31 |
#!/bin/bash |
| 32 |
ESCULATE="sudo" |
| 33 |
# ESCULATE="su -c" |
| 34 |
|
| 35 |
scriptpath=${BASH_SOURCE[0]} |
| 36 |
scriptname=${scriptpath##*/} |
| 37 |
|
| 38 |
IFS=':' |
| 39 |
|
| 40 |
for path in ${PATH}; do |
| 41 |
[[ -x ${path}/${scriptname} ]] || continue |
| 42 |
[[ ${path}/${scriptname} -ef ${scriptpath} ]] && continue |
| 43 |
|
| 44 |
elog "using ${ESCULATE} to execute ${path}/${scriptname} $@ as root..." |
| 45 |
${ESCULATE} ${path}/${scriptname} $@ |
| 46 |
|
| 47 |
exit 0 |
| 48 |
done |
| 49 |
exit 1 |
| 50 |

Done. |

| 61 |
The bonus part is that I have investigated the partition of sdcard to |
| 62 |
maximize Gentoo performance. Summarizing. |

It works now, similar to canadian cross compile actually. |
| 75 |
|
| 76 |
I can not cross-compile a native toolchain into a prefix. More on the |
| 77 |
steps to wiki. |

no reponse yet. |

Good news is that the council supports development of RAP[3]. I'll take |
| 92 |
more systematic way to integrate it into gentoo-x86 tree. At the same |
| 93 |
time training redlizard to join Gentoo for the development[4]. |
