Transcode will not compile in Slackware64-13.0, Multilib

I installed Slackware64-13.0 on this laptop on Sat 20090929. On Mon 20090931 I installed Eric's Multilib. I use sbopkg for most upgrades & last evening I attempted to install the sbopkg queuefile transcode_build.sqf. Everything built properly until it got to the transcode package, during which I got the following:

Code:

gcc -I/usr/include -I/usr/include/libxml2 -Wall -Wstrict-prototypes -Wmissing-prototypes -O2 -fPIC -o tccat tccat-tccat.o tccat-dvd_reader.o tccat-extract_avi.o tccat-fileinfo.o tccat-ioaux.o tccat-ioxml.o tccat-ts_reader.o  ../avilib/.libs/libavi.a /usr/lib64/libdv.so -L/usr/lib /usr/lib64/libdvdread.so /usr/lib/libxml2.so ../aclib/.libs/libac.a ../libtc/.libs/libtc.a -lm -lz -ldl   -Wl,--rpath -Wl,/usr/lib64 -Wl,--rpath -Wl,/usr/lib64

/usr/lib/libxml2.so: could not read symbols: File in wrong format

collect2: ld returned 1 exit status

make[3]: *** [tccat] Error 1

There is a file "/usr/lib/libxml2.so". There is also a file "/usr/lib64/libxml2.so". I have a desktop machine on which I have also installed Slackware64-13.0, but not Multilib. I have just now tried to install transcode from the .sqf file on the desktop & it worked perfectly. I can only assume (& you know what that does!) that this is some problem with the Multilib install. Is there some way to fix this, or am I safe in installing the package I made on the desktop onto this laptop?

Try the slackbuild here, that might work. I wonder if the slackbuild for that will work on a pure 64-bit system as well? Or will it also do multi-lib as well as regular 32-bit? :scratch: hrmm.

[edit]

I think that slackbuilds.org should say if the builds for 13 are universal, or specifically for 32-bit, 64-bit, or 64-bit multi-lib. That way it can remove some doubt on the builds. :jawa:

Could this have anything to do with it? From Eric's article:

Quote:

Compiling 32-bit programs

In case you need to compile a 32-bit program (wine and grub are two examples of open source programs that are 32-bit only) you first configure your shell environment by running the command:

. /etc/profile.d/32dev.sh

Note the 'dot' in front of the filename - that is actually part of the commandline! Running this command changes or creates several environment variables. The effect of this is, that 32-bit versions of binaries are preferred over 64bit binaries when you compile source code - you will be running a 32bit compilation. The effect will last until you logout from your shell.

In this changed environment, you will be able to use standard SlackBuilds to build 32-bit packages for Slackware64. There are two things to keep in mind:

1.
You will have to define the ARCH variable as 'x86_64' even though you are compiling a 32-bit program!
2.
You will have to edit the SlackBuild and if it wants to use 'lib64/' directories for “$ARCH = x86_64”, you will have to force it to use 'lib/' directories instead. Usually, this is accomplished by finding a definition like:

LIBDIRSUFFIX="64"

and changing this line to

LIBDIRSUFFIX=""

I had a problem with transcode also.
I messed with it quite awhile and then finally installed Slack64 on another partition without multi-lib to build packages on.
Transcode with all the options enabled built and worked on my Multi-Lib system.
Stellarium was another I had to build on my Slack64 non multi-lib system.
So far I've done:
gparted
gnucash <-- the source link for "slib" dosen't work on the SlackBuild site.
transcode
on Slack64 "no-libs" and all worked on the multi-lib system.

That is the slackbuild I ran, & it works well on a pure 64 bit system.
brianL:
As stated, the source/script works OK on a system w/o Multilib. I don't think I would need to install it as 32 bit.
slackass:
The "slib" link must be fixed, I installed gnucash from the .sqf file last night as well & it worked OK. The only reason I installed multilib on this laptop is that my daughter uses it a couple of times a week to play World of Warcraft, which runs OK under Wine. Until someone who knows more than I fixes it, I can compile on the desktop & install on the laptop.

With a multilib system, there is a little more to the story than the SlackBuild scripts of slackbuilds.org tell you.

There is a single line you have to add to that transcode.SlackBuild script so that the lib64 directory will be favoured over the lib directory when you compile 64bit binaries. I include that line in all of my own SlackBuild scripts (http://slackware.com/~alien/slackbuilds/) which is why I never had complaints from Slamd64 users ;-)

Right between the lines:

Code:

CXXFLAGS="$SLKCFLAGS" \

and

Code:

./configure \

add the following line (do not leave empty lines around it!):

Code:

LDFLAGS="-L/usr/lib${LIBDIRSUFFIX}" \

Now, your compilation will succeed if you set the ARCH variable to "x86_64".

Thanks Eric!
I know you've heard it before but here it is again:
Thanks for a Fantastic System!!

Indeed. That worked fine. Thanks, Eric

Ran into the same problem, found this thread, working fine now. I second the thanks to Eric, the multilib packages you put together are serving me great.

I also find this thread helpful in building GSB. I think you could add this tip in your multilib wiki...

for example:

sed -i 's/\.\/configure/LDFLAGS\=\"\-L\/usr\/lib\$\{LIBDIRSUFFIX\}\" \.\/configure/g' */*/*.SlackBuild
