_dl_hwcap is not a libxml2 symbol as far as I can see. Could you try running revdep-rebuild and/or check what in the libxml dependencies needs rebuilding.
Thx for replying! revdep-rebuild found something, but looked unrelated (a libdb-...so needed by perl and python). Since then some other packages failed with a similar error, so it is not specific to libxml2. I found that _dl_hwcap is a variable in glibc, a "mask for hardware capabilities that are available" and is used in all kinds of processor-specific assembler code, too difficult for me to look into further. Here is the output of 'emerge audiofile'. /bin/sh ../libtool --mode=link powerpc-unknown-linux-gnu-gcc -O2 -mcpu=powerpc -mtune=powerpc -fno-strict-aliasing -pipe -o linuxtest linuxtest.o ../libaudiofile/libaudiofile.la -lm powerpc-unknown-linux-gnu-gcc -O2 -mcpu=powerpc -mtune=powerpc -fno-strict-aliasing -pipe -o .libs/power power.o ../libaudiofile/.libs/libaudiofile.so -lm /mnt/matrox/usr/powerpc-unknown-linux-gnu/gcc-bin/4.1.1/../../../lib/gcc/powerpc-unknown-linux-gnu/4.1.1/../../../libm.a(w_sqrt.o): In function `sqrt': (.text+0xa): undefined reference to `_dl_hwcap' /mnt/matrox/usr/powerpc-unknown-linux-gnu/gcc-bin/4.1.1/../../../lib/gcc/powerpc-unknown-linux-gnu/4.1.1/../../../libm.a(w_sqrt.o): In function `sqrt': (.text+0x16): undefined reference to `_dl_hwcap' /mnt/matrox/usr/powerpc-unknown-linux-gnu/gcc-bin/4.1.1/../../../lib/gcc/powerpc-unknown-linux-gnu/4.1.1/../../../libm.a(e_sqrt.o): In function `__ieee754_sqrt': (.text+0x18a): undefined reference to `_dl_hwcap' /mnt/matrox/usr/powerpc-unknown-linux-gnu/gcc-bin/4.1.1/../../../lib/gcc/powerpc-unknown-linux-gnu/4.1.1/../../../libm.a(e_sqrt.o): In function `__ieee754_sqrt': (.text+0x192): undefined reference to `_dl_hwcap' collect2: ld returned 1 exit status make[2]: *** [power] Error 1
Oh, I tried emerging the newest glibc, no difference. Then I tried downgrading to an older glibc, but I got an error somewhat like "Sanity check: downgrading glibc is a sure way to destruction!" :)
reassigning to toolchain, they'll know better than me what might be the problem
_dl_hwcap is an internal glibc variable ... nothing should be referring to it outside of glibc ... when you say "latest glibc version", what version are you talking about ? the output from sndfile looks screwed up ... it should not have been linking against the static libm which implies your /usr/lib/libm.so does not exist try doing something simple like: echo 'int main(){return sqrt((unsigned long)main);}' > test.c gcc test.c -lm
(In reply to comment #5) > the output from sndfile looks screwed up ... it should not have been linking > against the static libm which implies your /usr/lib/libm.so does not exist You were completely right, /usr/lib/libm.so wasn't found. You see I mounted an external hard drive that I can't boot from and instead of making several partitions for /usr, /var, /home etc.. I thought I could get away with linking e.g. /usr to ln -s /mnt/matrox/usr /usr That worked well for a while but libm.so (and others in /usr/lib) are symlinks themselves, with a relative path (../../lib/libm.so). That should point to /lib, but now didn't. So if glibc is not supposed to play nice with symlinks, then it;s not a bug. BTW, the output of your one liner was again an undefined reference to `_dl_hwcap'. Thx for helping!
yeah, symlinking /usr is known to be funky use a bind mount instead: mount --bind /mnt/matrox/usr /usr that should work for most everything ...
