Re: [png-mng-misc] PNG12_0, libpng12.so.0 on Sol10

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Further investigation has shown.....

Taking the source and compiling on Sol10 and RHEL5u3 produces a similar Makefile in that they both contain:

Makefile:       echo PNG12_0 '{global:' > $@.new<mailto:$@.new> (sol10)
Makefile:       echo PNG12_0 '{global:' > $@.new<mailto:$@.new> (RHEL)

Here is the extract from the Makefile.....
 libpng.vers: libpng.sym
        rm -f $@ $@.new
        echo PNG12_0 '{global:' > $@.new
        $(SED) s/$$/\;/ libpng.sym >> $@.new
        echo 'local: *; };' >> $@.new
        mv $@.new $@

but after issuing make, the results are different:

for RHEL
strings .libs/*|grep PNG12
PNG12_0
PNG12_0
PNG12_0
from
libpng12.so
PNG12_0
libpng12.so.0
PNG12_0
libpng12.so.0.44.0
PNG12_0

for Sol10
strings .libs/*|grep PNG12
nothing...

Does anyone have any ideas why this would be?

Cheers

Sean

Hi folks,

got a problems with regards running cups-1.4.4 on Sol10 related to libpng12.so.0 that someone may have run into.

1. The following filters always fail due to the following error:

./bannertops
ld.so.1: bannertops: fatal: libpng12.so.0: version `PNG12_0' not found (required by file /opt/csw/lib/libcupsimage.so.2)
ld.so.1: bannertops: fatal: libpng12.so.0: open failed: No such file or directory

ldd bannertops
        libcupsimage.so.2 =>     /opt/csw/lib/libcupsimage.so.2
.....
        libpng12.so.0 =>         /usr/lib/libpng12.so.0
        libpng12.so.0 (PNG12_0) =>       (version not found)
        libjpeg.so.8 =>  /usr/local/lib/libjpeg.so.8

bash-3.00# ./rastertolabel
ld.so.1: rastertolabel: fatal: libpng12.so.0: version `PNG12_0' not found (required by file /opt/csw/lib/libcupsimage.so.2)
ld.so.1: rastertolabel: fatal: libpng12.so.0: open failed: No such file or directory
Killed

So, has anyone run into this issue? I've searched high and low for this PNG12_0 issue, but cannot find anything of relevance...
