Bug 125708 – zlib fails to build a shared lib

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description João Eduardo Ferreira Bertacchi 2006-03-10 06:34:57 UTC]

This problem occured on a emerge -e system (building stage3).
I noticed that zlib ebuild is creating the link /lib64/libz.so -> /usr/lib64/libz.so but at the end it is deleted.

/lib64/libz.so shouldnt be pointing to stuff /usr/lib64/

post the log as an attachment: `emerge zlib >& log`

[Comment 2 João Eduardo Ferreira Bertacchi 2006-03-10 10:59:09 UTC]

emerge zlib

After I emerge zlib, there isn't /lib64/libz.so link. I noticed that there is a file named libz.so in /usr/lib64 and I make by hand a link to it.

[Comment 3 SpanKY 2006-03-10 11:37:24 UTC]

no, your problem is that zlib doesnt generate a shared lib at all:
>>> Source unpacked.
./configure: line 80: -fPIC: command not found
Checking for shared library support...

run `emerge --debug zlib >& log` and post that as an attachment

"# emerge --debug zlib" output

[Comment 5 SpanKY 2006-03-10 14:04:30 UTC]

ok, that doesnt work ... try this:
edit /usr/portage/sys-libs/zlib/zlib-1.2.3.ebuild
change the line './configure ......' to read 'sh -x ./configure ......'
then run MAKEOPTS=-j1 emerge zlib >& log

[Comment 6 João Eduardo Ferreira Bertacchi 2006-03-10 15:36:22 UTC]

Created attachment 81874 [details]
'MAKEOPTS=-j1 emerge zlib >& log' with changed ebuild

Before run emerge I did 'ebuild zlib-1.2.3.ebuild digest'

[Comment 7 SpanKY 2006-03-10 16:00:44 UTC]

your sync is up to date right ?  also, what version of bash do you have ?

can you post your 
/var/tmp/portage/zlib-1.2.3/work/zlib-1.2.3/configure as an attachment so we can be sure it isnt screwed up ...

[Comment 9 João Eduardo Ferreira Bertacchi 2006-03-13 10:23:45 UTC]

I didn't sync (and I'd like to don't sync). I'm using the release 2006.0.
I'm creating a new system from stage 1 in a system that still works. I use chroot to change the root to other dir and I run emerge from new root.

[Comment 10 SpanKY 2006-03-13 10:41:09 UTC]

ugh, no wonder it isnt working

[Comment 11 SpanKY 2006-03-13 10:42:18 UTC]

sync your tree and dont bother filing a bug again w/out doing so because you'll just waste our time chasing bugs that were fixed already

[Comment 12 João Eduardo Ferreira Bertacchi 2006-03-13 11:54:33 UTC]

I'm sorry and thanks for your time.
After sync, for my shame, it works.
Sorry again.
