./boinc: symbol lookup error: ./boinc: undefined symbol: gzopen64

[jgxenite]

I recently noticed that Boinc 5.10.28 had stopped running on my computer. I can find no reason for this, except for this error message that appears when running the client:

./boinc: symbol lookup error: ./boinc: undefined symbol: gzopen64

It has been doing this now for approximately two days. I found posts on various forums relating this error to libxml, but I have not updated my libxml packages (version 2.6.30-1 under Fedora 8) since installing Fedora 8 about a month ago.

Lowering priority, just because I have never seen this reported before.

This is happening on my Gentoo install as well when BOINC tries to upload a result:

I have sys-libs/zlib-1.2.3-r1
which does not appear to contain gzopen64:
#objdump -T /lib/libz.so.1 | grep open

I updated the BOINC client from 5.10.21, which was working fine for me (but manager was not working)

I have the same problem when uploading results:

And one more, reported on ​Cosmology@Home:

Returning priority to Major.

I downloaded the source for 5.10.42, compiled it and no longer have this issue.

[MichaelBuckingham]

I think whats happening is a zlib issue...zlib.h converts gzopen over to *64 calls when _FILE_OFFSET_BITS is 64 but cant define the prototypes unless _LARGEFILE64_SOURCE is also defined...incorrectly calling gzopen64.

Not sure it's a BOINC issue...??

testes on clean Scientific Linux 5.1, Kernel 2.6.18-53.1.21.el5, standard RHEL libcurl

[Eric Korpela]

Should be fully fixed in check-in 15530.

[Nicolas]

Fixed in [15530].

Looks like Trac only looks for "fix #1234" or "fixes #1234", not "fixes ticket #1234".

[romw]

should be fixed in latest 6.2 release
