[Octave-bug-tracker] [bug #41711] Build fails for libtool: moc-file-editor-interface.cc: PIC: No such file or directory

[anonymous]

Follow-up Comment #3, bug #41711 (project octave):

Mike and John,

Thank you very much for your quick responses. I greatly appreciate the
detailed notes and comments that help me learn more on the way... Here is my
feedback after working on the various bits.

1. Indeed, the "-fPIC" option was the redundant element that broke the build.
I clearly copied it from a different "configure" statement without knowing
where it would lead.

2. The "--with-qhull" option I inserted explicitly during earlier attempts
because "configure" was failing to locate the QHull library after manually
building the package on the machine. Including the full QHull path in the
flags did the trick, instead, and I just never got to remove the older
option.

3. The "--enable-shared" option was also a left-over I found from earlier
forum searches in the hope of getting Octave to locate some of the other
libraries I used.

4. I believe I had just about all corners covered by specifying "--enable-64",
particularly after having carefully reviewed the relevant reference that John
sent me, too. However. later at the "make check" stage I got a panic in lu.cc,
and this prompted me to try out a build without this option; see the end of my
message.

Going past the hurdle caused by the "-fPIC" option, I got stuck a couple more
times later in the build:

5. The first was caused by getting a core dump upon execution of:
lrelease -qm languages/be_BY.qm languages/be_BY.ts
I searched a bit, found that it is Qt4 related, but I have no idea what may
have caused it to produce a segmentation fault on my system. I simply skipped
over this part by blanking out the LOCALES= arguments in line 2084 and
commenting out lines 4006-4008 in the libgui Makefile.

6. The last obstacle was my LaTeX default settings: While building the
documentation, I got at some point the following error:
./octave.aux:4743: TeX capacity exceeded, sorry [save size=5000].
I searched and fixed it by going to line 526 of
"/usr/share/texmf/web2c/texmf.cnf" and increasing the default limit of
save_size. A 10x increase from 5000 to 50000 worked more than fine.

Finally, I ran "make check" and got the following results:
  PASS     11463
  FAIL         2
  XFAIL        7
  SKIPPED     58
The failed tests reported were:
  scripts/sparse/svds.m ............... PASS    5/6    FAIL 1
  scripts/testfun/assert.m ............ PASS   87/88   FAIL 1
and the skipped functions (clearly, due to skipping the Magick++ and JIT
dependencies) are:
gui: uimenu
image: imformats, imread
optimization: qp
util: copyobj, findall, graphics_tookit
and the jit.tst

Many thanks again,
Alexander.
