# Convienence class for extracting RPMs

|
|
# Basically, rpm_src_unpack does:
|
| 10 |
|
|
#
|
| 11 |
|
|
# 1. convert all *.rpm in ${A} to tar.gz, non rpm files are passed through
|
| 12 |
|
|
# unpack()
|
| 13 |
|
|
# 2. unpacks the tar.gz into ${WORKDIR}
|
| 14 |
|
|
# 3. if it is a source rpm, it finds all .tar .tar.gz, .tgz, .tbz2, .tar.bz2,
|
| 15 |
|
|
# .zip, .ZIP and unpacks them using unpack() (with a little hackery)
|
| 16 |
|
|
# 4. deletes all the unpacked tarballs and zip files from ${WORKDIR}
|
| 17 |

|
|
# Sometimes, pure rpm2targz will fail on certain RPMs (eg: scim-chinese)
|
| 21 |
|
|
# because their code for detecting RPM header offset is not good enough.
|
| 22 |
|
|
# In that case, you need to add app-arch/rpm to your DEPEND. rpm2targz
|
| 23 |
|
|
# will automatically find rpm2cpio and use it instead of its own rpmoffset.
|
| 24 |

# In addition, rpm2targz-8.0 behaves differently from rpm2targz-9.0. The newer
|
| 26 |
|
|
# versions will autodetect rpm2cpio whereas 8.0 doesn't.
|
| 27 |
|
|
#
|
| 28 |
|
|
# Also, 9.0 wil# detect if it is a source rpm and place files in
|
| 29 |
|
|
# ${prefix%.src} whereas 8.0 will just place them in the current directory.
|
| 30 |
|
|
# As of writing, the current rpm2targz-9.0 in portage has been patched to
|
| 31 |
|
|
# remove this behaviour for backwards compatibility.
