'bug' in mythtv register use?

Hello all.

On my new SuSE Linux 8.2 setup, mythtv won't compile, it keeps giving
this error:

gcc -c -pipe -O2 -march=i586 -mcpu=i686 -fmessage-length=0 -fPIC

A bit of searching on google got me this:
http://lists.debian.org/debian-gcc/2002/debian-gcc-200207/msg00094.html

Another suggested that removing PIC from the compilation should work
just fine. I'm trying to see if I can get that to happen right now:
http://lists.debian.org/debian-gcc/2002/debian-gcc-200207/msg00089.html

As you can see, it only seems to happen in libavcodec.
.. Okay, it seems everything compiles if i remove -fPIC from the
Makefile in the libavcodec catalog. At least that's a way around it for
now. Next is to see if it also works :)

Well, either the lack of -fPIC broke something or more things are
problematic with GCC 3.3:

g++ -c -pipe -O2 -march=i586 -mcpu=i686 -fmessage-length=0 -fPIC
-DNO_DEBUG -Wall -W -O6 -march=pentiumpro -fomit-frame-pointer

make[1]: *** [sub-libmythtv] Fejl 2

make: *** [sub-libs] Fejl 2

That seems to indicate some code needs altering in the future to work on
modern systems. Maybe it will even help stability?

I'm not sure what to do about this...

The best thing would be to not use compilers that are not yet officially
released.

That asm statement should be omitted if you are building with PIC. Try
using -DPIC in addition to -fPIC.

Try adding #include <assert.h>

How did you end up building with -fPIC in the first place? Did you try to
configure it to build a shared library? If so, don't do that.

Fixed in CVS.

Re: 'bug' in mythtv register use? [In reply to]

I ran ./configure without arguments, I even tried ./configure
--disable-shared, but it didn't seem to have any effect. The minute I
wrote 'make' after ./configure (either case) qmake inserted this -fPIC
business.. I even checked the config.mak file and it was not listed in
there, which have me fairly puzzled at this whole thing...

Re: 'bug' in mythtv register use? [In reply to]

Replying to my own message, I'd just like to say that I now got myth to
compile with libs/libavcodec stripped for any type of PICs and
avformatdecoder.cpp having an #include <assert.h> line in it (I put one
in nuppeldecoder.cpp as well, not sure if it was needed).
That is pretty doable for now and it seems Isaac is right and GCC 3.3 is
not yet official. I'm surprised SuSE has used it, then, but why complain
-- my system is quite a bit faster than before (as least it seams to
be).

/Martin.

: bjm[at]moktoo ; ./configure
Please note that these settings only deal with libavcodec, not MythTV.
Install prefix /usr/local

Re: 'bug' in mythtv register use? [In reply to]

I am aware that configure only deals with libavcodec, but it has to be
run, does it not?

My 'problem' seems to lie with qmake, it seems:

#############################################################################
# Makefile for building: libavcodec.a
# Generated by qmake (1.04a) (Qt 3.1.1) on: Mon Apr 14 22:44:33 2003
# Project: libavcodec.pro
# Template: lib
# Command: $(QMAKE) -o Makefile libavcodec.pro
#############################################################################

This makefile is not generated by simply runing configure and the
options that ought to set -fPIC to on are not activated... ?!
