acrobat reader on slackware64

As a side note, I wish the various SlackBuilds would use the .bin file as a source instead of the .tar.bz2 file, since it is approximately 13.5 Mb smaller due to use of LZMA compression (the same type of high compression used in 7z and xz files).

The .bin actually has a .tar.lzma archive inside it with the exact same files as the .tar.bz2 that is currently used as a source. The contents of this compressed tar can be extracted by either of the following commands:

Code:

$ tail -c+6889 AdbeRdr9.5.5-1_i486linux_enu.bin | bsdtar xvf -

Code:

$ tail -c+6889 AdbeRdr9.5.5-1_i486linux_enu.bin | xz -qqd | tar xv

The value 6889 marks the start of LZMA compressed tar. This value has not changed in all releases of Acroread since .bin files where first offered (i.e. AdbeRdr9.1.0-1_i486linux_enu.bin from February 2009), so it should be relatively safe just to hardcode this value.

For background, I calculated it by using a Regex to search for the start of a typical LZMA stream and printing its position, like so (adding 1 to the resultant value.):

Code:

$ grep -Pabom1 ']\x00{2}.{4}\xff{6}' AdbeRdr9.5.5-1_i486linux_enu.bin
6888:]�������

I did once suggest this (approximately 8 months) to the maintainer for the SBo SlackBuild but never heard back (although the Arch PKGBUILD maintainer did take my suggestion). Here is a suggested patch to the SBo SlackBuild:

Code:

+tail -c+6889 $CWD/AdbeRdr${VERSION}-1_${ARCH}linux_${ADOBE_LANG}.bin | bsdtar xvf -
 
 VERSION=${VERSION}_$ADOBE_LANG

P.S. I learnt the trick of finding compressed files within another file when I once attempted to make the smallest possible rpm2cpio in shell script. I managed it in 8 lines.

@sbabaro1: Curious if this (above) worked out for you. I'm concerned you might have missed this reply following my off-topic response. I have not tested a stripped binary myself but judging by the Arch Linux thread and others I found when Googling the error message you mention, it does seem like stripping might be the cause of your problems.

Thanks for the reply, I'll test the SBo package soon
I'll be back to confirm if worked

I can confirm that using SBo script, adobe works correctly

thanks all

Cool, remember to mark the thread as solved!
