[gentoo-user] problems with csound ebuild

hello list,

i need some help to come up with an ebuild for csound (a language for
sound synthesis). 

csound uses scons and then installs files using a script called
install.py. compilation goes fine. 

executables, libraries, plugins and header files are correctly
installed (under /usr/bin, /usr/lib, /usr/lib/csound/plugins/
and /usr/include/csound/ respectively)

but i'm having a bunch of messages like this when it comes to installing
localization files:

 === Installing Localisation files ===
ACCESS DENIED  unlink:    /usr/share/locale/de/LC_MESSAGES/csound5.mo
install: cannot remove `/usr/share/locale/de/LC_MESSAGES/csound5.mo':
Permission denied
 *** error copying /usr/share/locale/de/LC_MESSAGES/csound5.mo

this is the summary:

------------------ ACCESS VIOLATION SUMMARY --------------------------- 
LOG FILE = "/var/log/sandbox/sandbox-15019.log"

unlink:    /usr/share/locale/de/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/en_GB/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/en_US/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/es_CO/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/fr/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/it/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/ro/LC_MESSAGES/csound5.mo
------------------------------------------------------------------------

i can circumvent this emerging with FEATURES="-sandbox", but i'd like
to solve this in a cleaner way.


the relevant (i think) part in the script is this:

print ' === Installing Localisation files ==='
xmgList = findFiles('.', '.+\\.xmg')
if xmgList.__len__() > 0:
    err = installFiles(xmgList, xmgDir)
    installErrors = installErrors or err
else:
  xmgList = ['de', 'en_GB','en_US', 'es_CO', 'fr', 'it','ro']
  for i in xmgList:
    makeDir(concatPath([xmgDir, i, 'LC_MESSAGES']))
    src = 'po/' + i + '/LC_MESSAGES/csound5.mo'
    fileName = concatPath([xmgDir, i, 'LC_MESSAGES/csound5.mo'])
    err = runCmd(['install', '-p', '-m', '0644', src, fileName])
    if err == 0:
        addMD5(fileName, fileName)
        print '  %s' % fileName
    else:
        print ' *** error copying %s' % fileName
        installErrors = installErrors or err


the ebuild is attached, any help greatly appreciated.

best,

lj

Can you emerge attr, then run lsattr on the files that cannot be
unlinked? I suspect that they might have extended attributes
preventing those file from being deleted. If you do have extended
attributes, you can remove them using chattr, I've had extended
attributes appear before and to this day don't understand why they
showed up.

thanks for your answer, that doesn't seem to be the problem, though. 
i can install everything using install.py directly (not emerging with
portage). also, using FEATURES="-sandbox" i can emerge without
problems. so this problem seems to be related to the "sandbox",
something i never got to understand completely...

Have you updated python recently and did not run python-updater? You can
also try to re-emerge scons.


Sandbox errors are mostly caused when the ebuild tries to access the
filesystem directly instead of using $WORKDIR.

Maybe some parts of install.py do not honor --instdir="${D}".

I guess you need to invoke instdir in src_compile too, at least it is an
option available in Sconstruct.

that seems to be the problem, but IANAP and i don't read python... :-(
