//lib/libm.so.5: could not read symbols: Bad value and /usr/bin/ld: : invalid DSO for symbol `sin@@FBSD_1.0' definition

[Mark Millard]

For 10.1-??? I've been getting:

/usr/bin/ld: : invalid DSO for symbol `sin@@FBSD_1.0' definition
//lib/libm.so.5: could not read symbols: Bad value
*** [fractals] Error code 1

make[6]: stopped in /usr/obj/portswork/usr/ports/graphics/freeglut/work/freeglut-2.8.1/progs/demos/Fractals

when I attempt to portmaster xscreensaver. (The rest of the ports I try to build work fine, including all their dependencies. If xscreensaver finished it would be about 409 ports involved in all.)

I now note it to the list because I've now tried on on powerpc/GENERIC and powerpc64/GENERIC64 with and without /etc/make.conf having:

WITH_DEBUG_FILES=
WITHOUT_CLANG=
WITH_DEBUG=

[WRKDIRPREFIX=(path not listed here) always present]

when I buildworld kernel and use portmaster for the ports.


It appears that no matter what style of build on a PowerMac under either powerpc/GENERIC or powerpc64/GENERIC64 /lib/libm.so.5 ends up with this problem (or the ld checks for invalid DSO's end up wrong  --or both).


I first noticed this with 10.1-PRERELEASE

FreeBSD FBSDG4S0 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r271215: Sat Sep  6 23:56:15 PDT 2014     root at FBSDG4S0:/usr/obj/usr/src/sys/GENERIC  powerpc

I can not claim just what was the last prior working case I had with 10.0-STABLE but all those were "as distributed" installs instead of personal "buildworld kernel" based on a source updates. For 10.1-??? I've been experimenting with source based tracking/building, mostly building on Quad-core PowerMac G5s (booted with either GENERIC based or GENERIC64 based worlds/kernels, up to DDB/GDB being added or not). Here GENERIC and GENERIC64 were not updated at all.

It has continued with the likes of

FreeBSD FBSDG4S1 10.1-BETA1 FreeBSD 10.1-BETA1 #1 r271610M: Wed Sep 17 21:47:20 PDT 2014     root at FBSDG4S1:/usr/obj/usr/src/sys/GENERIC  powerpc

and its GENERIC64 variant. (M in r271610M because of DDB and GDB options added to GENERIC and GENERIC64.)
