Bug 10786 – festival ebuild is hard coded for i686 w/ gcc3.2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description J Robert Ray 2002-11-15 12:17:27 UTC]

This bit here:

        if [ ${GCCPV} != "2.95.3" ] ; then
                echo
"COMPILERLIBS=/usr/lib/gcc-lib/i686-pc-linux-gnu/${GCCPV}/libstdc++.a
/usr/lib/gcc-lib/i686-pc-linux-gnu/${GCCPV}/libgcc_s.so.1" >> ${T}/config/config
        fi


Fails to compile on my i586 box because there is no .../i686-pc-linux-gnu/...
library.

YAR! You're right it seems. Ought to be able to pull that from a var somewhere
though. Thanks for the heads up!

[Comment 2 Matt Keadle 2002-11-15 16:04:19 UTC]

On your box, I'm guessing that directory is called:

/usr/lib/gcc-lib/i586-pc-linux-gnu ?

Yeppers.  But what about ppc?

[Comment 4 Matt Keadle 2002-11-15 17:43:31 UTC]

I'm testing replacing the i586,i686,etc.. with the output of `uname -m`. Can you
think of a better way?

[Comment 5 J Robert Ray 2002-11-15 17:59:59 UTC]

`uname -m` may not work because on ppc that would yield 'ppc-pc-linux-gnu' and
that is unlikely to be correct.  Looking at the gcc ebuild, it probably uses
$CHOST when it places that library and so using $CHOST here would be better.

[Comment 6 Matt Keadle 2002-11-16 06:23:59 UTC]

Done. -r2 is commited. Also, with the help of Sascha (cybersystem), we've got it
compiling on ppc as well. Woohoo! I can sleep now.

[Comment 7 J Robert Ray 2002-11-26 06:45:29 UTC]

-r2 still doesn't work for me.

My kernel is configured as 'CyrixIII/VIA-C3/VIA-C5'.
uname -r emits "i686" so -r2 still looks for i686-pc-linux-gnu.

My CHOST is set to "i586-pc-linux-gnu".  i686 binaries do not run on my system.
 I really don't know where uname gets off calling my cpu a i686.

Another reason not to use `uname -r`: a situation similar to mine could come up
if someone has decided to not optimize for their CPU and is using
i386-pc-linux-gnu for their CHOST.

I believe CHOST determines the name of the library produced by gcc, it is only
in parity with uname -r in most but not all cases.  The CHOST in the ppc profile
is set to "powerpc-unknown-linux-gnu" which is exactly what you are setting
ARCHTYPE to in -r2 on ppc.

I propose:

        if [ ${GCCPV} != "2.95.3" ] ; then
-    [ `uname -m` = "ppc" ] \
-               && ARCHTYPE="powerpc-unknown" \
-               || ARCHTYPE="`uname -m`-pc"
-       echo
"COMPILERLIBS=/usr/lib/gcc-lib/${ARCHTYPE}-linux-gnu/${GCCPV}/libstdc++.a
/usr/lib/gcc-lib/${ARCHTYPE}-linux-gnu/${GCCPV}/libgcc_s.so.1" >> ${T}/config/config
+               echo
"COMPILERLIBS=/usr/lib/gcc-lib/${CHOST}/${GCCPV}/libstdc++.a
/usr/lib/gcc-lib/${CHOST}/${GCCPV}/libgcc_s.so.1" >> ${T}/config/config
        fi

Excuse the word-wrap.

Please post your modified ebuild.

Created attachment 5981 [details]
festival-1.4.2-r3.ebuild

Uses $CHOST.  WFM

Thanks jrray. Changes are in and commited. What will reopen this bug next?
