Hello, for both 5.22.00-r2 and 5.24.00 with the latest --as-needed from bug 280925 compiled with -Wl,--as-needed at LDFLAGS I encounter runtime freeze after the following actions: 1) ran root as usual without any macro or data files on CLI: $ root -l 2) Create TBrowser object: new TBrowser 3) Open a root file with TTree in it. ...and root freezes, both TBrowser and CINT interpreter. If I recompile without --as-needed it works ok. I reemerge my whole tree with --as-needed via LDFLAGS, but this doesn't help. If one run root with data file specified on CLI, TBrowser works ok and you can view specified file or open other files as well. I suspect CINT + --as-needed problems, maybe CINT was not designed to work with --as-needed due to run-time linking issues. But I am not sure and I have no any clue on how to handle this. If someone can confirm this bug, it would be a good idea to disable --as-needed for this package. I can upload a sample file if someone is interested in.

I will wrangle your bug but please be sure it's valid! Did you test it with more _sane_ C{XX}FLAGS?
(In reply to comment #1) > I will wrangle your bug but please be sure it's valid! Did you test it with > more _sane_ C{XX}FLAGS? OK, I tested it with CFLAGS="-O2 -march=core2" and CXXFLAGS=${CFLAGS} (root will not compile with -march=i386). And of course, nothing changed: it freezes with --as-needed and works OK without it. On my first posting I thought provided arguments are more than enough to convince that this is --as-needed triggered issue.

Sorry I haven't use root for a while. Could you provide the exact test you did and with the file and the use flags, so I can reproduce? Thanks.
I fail to see how -as-needed can be the root cause for this since it only affects the linker (unless it is a linker bug). Could you provide the strace output so we can see what root is doing. Thanks, Markus
Created attachment 206577 [details] test sample Hello, (In reply to comment #3) > Sorry I haven't use root for a while. Could you provide the exact test you did > and with the file and the use flags, so I can reproduce? > Thanks. Test file is attached. Steps to reproduce: 1) root -l root [0] new TBrowser 2) Open test.root via TBrowser interface, then root freezes in my case. Here are my use flags for root: cern clarens doc examples fftw geant4 math mysql pythia6 pythia8 python qt4 reflex ssl xml xrootd -afs -cint7 -debug -emacs -kerberos -ldap -odbc -openmp -oracle -postgres -ruby -xinetd
Created attachment 206579 [details] strace output of freeze Hi, (In reply to comment #4) > I fail to see how -as-needed can be the root cause > for this since it only affects the linker (unless it > is a linker bug). Could you provide the strace output > so we can see what root is doing. ROOT is not just an app, it contains its own interpreter with dynamic library loading, that's why --as-needed affect it. Another test: in my previous message I pointed out a way to reproduce a bug, but if you'll call gSystem->Load("libTree"); in interpreter prior to creation of TBrowser object it will open sample file without a problem. strace output is attached. One can see infinite loop in library access.
I have disabled as-needed in the just committed 5.24.00-r1. Leaving this bug open for now.
hi it seems that root-5.26.00-r2 does fine with as-needed. could you check on your side too, by removing the no-as-needed from the ebuild and adding it to your LDFLAGS? thanks
Hello, with --as-needed it is not even possible to compile root-5.26.00-r2 with the following flags: USE="afs clarens doc examples fftw geant4 kerberos math mysql opengl pythia6 pythia8 qt4 reflex ssl xft xml xrootd -cint7 -emacs -ldap -odbc -openmp -oracle -postgres -python -ruby -xinetd" It fails here: g++ -m32 -march=athlon-xp -m32 --param l1-cache-line-size=64 --param l1-cache-size=64 --param l2-cache-size=512 -O2 -funswitch-loops -fpredicti ve-commoning -fgcse-after-reload -fomit-frame-pointer -ftree-loop-linear -floop-interchange -floop-strip-mine -mfpmath=sse -pipe -Wl,-O1 -Wl,-- as-needed ../../obj/XrdFrmAdminMain.o ../../obj/XrdFrmAdmin.o ../../obj/XrdFrmAdminAudit.o ../../obj/XrdFrmAdminFiles.o ../../obj/XrdFrmAdminFi nd.o ../../obj/XrdFrmAdminQuery.o ../../obj/XrdFrmAdminUnlink.o ../../obj/XrdXrootdMonitor.o ../../obj/XrdScheduler.o -lreadline -lncurses -ln sl -lpthread -lrt -ldl -lc -L../../lib -lXrdFrm -lXrdCms -lXrdOss -lXrdNet -lXrdOuc -lXrdSys -o ../../bin/frm_admin ../../lib/libXrdOss.a(XrdOssAio.o): In function `XrdOssFile::Fsync(XrdSfsAio*)': XrdOssAio.cc:(.text+0x5e): undefined reference to `aio_fsync64' ../../lib/libXrdOss.a(XrdOssAio.o): In function `XrdOssFile::Read(XrdSfsAio*)': XrdOssAio.cc:(.text+0x29c): undefined reference to `aio_read64' ../../lib/libXrdOss.a(XrdOssAio.o): In function `XrdOssFile::Write(XrdSfsAio*)': XrdOssAio.cc:(.text+0x4d8): undefined reference to `aio_write64' ../../lib/libXrdOss.a(XrdOssAio.o): In function `XrdOssAioWait(void*)': XrdOssAio.cc:(.text+0x93f): undefined reference to `aio_error64' XrdOssAio.cc:(.text+0x95b): undefined reference to `aio_return64' collect2: ld returned 1 exit status Unresolved symbols belong to librt: $ symlookup -qr "aio_.*64" /lib/librt-2.11.1.so: aio_return64 /lib/librt-2.11.1.so: aio_cancel64 /lib/librt-2.11.1.so: aio_fsync64 /lib/librt-2.11.1.so: aio_error64 /lib/librt-2.11.1.so: aio_read64 /lib/librt-2.11.1.so: aio_suspend64 /lib/librt-2.11.1.so: aio_write64 and -lrt is before -lXrdOss, so failure is predictable. Without --as-needed it compiles normally.
Alright, I bumped a new revision: root-5.26.00-r3 with a big patch from upstream, more LDFLAGS propagation and as-needed fixes. Right now the ebuild allows as-needed, so please test. Thanks.
(In reply to comment #10) After some base tests r3 works still fine for me (with --as-needed).
