aixtools.git installation path

(1/1)

Hi Michael

Do you install the hole package content directly to /opt, how can I move it to /opt/aixtools.git instead... can I relocate the path during installation?

Michael:
I have never tested using the relocation flags of installp. (See: https://www.ibm.com/support/knowledgecenter/ssw_aix_72/install/reloc_app_packaging.html)


The fastest way for me will be to repackage it. But that is not likely to be this week - as I am preparing a presentation on Ansible.


You need the prefix to be /opt/aixtools, or /opt/aixtools.git?

While you do not have to answer - I am curious why the prefix /opt is not okay.

FYI: I have been considering - for some time - to change my prefix to /opt/aixtools.

Michael:
No guarantees - but an interesting question - so:

# mkdir /opt/aixtools.git
# mkdir /opt/tmp.git
# cd /opt/tmp.git
# restore -xqf /tmp/aixtools.git.2.24.1.0.I...
x ./opt/libexec/git-core/mergetools/vimdiff2
x ./opt/libexec/git-core/mergetools/vimdiff3
x ./opt/libexec/git-core/mergetools/winmerge
x ./opt/libexec/git-core/mergetools/xxdiff
# ls

# cd opt# ls

# mv * /opt/aixtools.git
# cd /opt/aixtools.git
# ls bin
git                 git-cvsserver       git-receive-pack    git-shell           git-upload-archive  git-upload-pack     gitk
# ldd bin/git
bin/git needs:
         /usr/lib/libc.a(shr_64.o)

         /usr/lib/libc.a(shr.o)
         /usr/lib/libcrypt.a(shr.o)
# bin/git --version
git version 2.24.1

Up to here - so good - except - this is not managed by installp.

Just taking one example, there is some hope - assuming the main program finds /opt/aixtools.git/libexec/*

# file libexec/git-core/git-http-fetch
libexec/git-core/git-http-fetch: 64-bit XCOFF executable or object module not stripped
# ldd libexec/git-core/git-http-fetch
libexec/git-core/git-http-fetch needs:
         /usr/lib/libc.a(shr_64.o)
         /usr/lib/libpthread.a(shr_xpg5_64.o)
         /usr/lib/libz.a(libz.so.1)
         /usr/lib/libcrypto.a(libcrypto64.so)
         /usr/lib/libssl.a(libssl64.so)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)
         /usr/lib/libc.a(shr.o)
         /usr/lib/libcrypto.a(libcrypto64.so.1.0.0)
         /usr/lib/libcrypt.a(shr.o)

So, you could try just moving everything to the directory you want it at. MAYBE it will work - almost out of the box.

soeme:
OK, thank you for this sample.
For me makes more sense to prefix static application in it's own directory, but this is my personal opinion ;-)

Is it correct that all static links are absolut and not relative to the libexec's - A recompile is mandatory for all?

Michael:
I do not worry myself with how packages call themselves - I have no idea how git finds 'helper' programs.

And, while I do use the term static - as to the libraries git uses - embedded is perhaps a better word, i.e., it is not making as much use of dlopen() (viewable by ldd output).

The prefix '/opt' was chosen to specifically not (re-)use and filepath already in use by others (e.g., AIX, BULL Freeware, Michael Perzl, AIXToolbox).

In short, it is possible - from my packages perspective - to have, e.g., the AIX Toolbox version of git installed.

I am working on an Ansible project - that would make it possible to use Ansible to load software packages - including dependencies. And, if that starts to work well I may even consider having dependencies (again).
