cross sparc64 chapter 5 glibc tls error
Following the "Version 7.0-cross-lfs-20050928-Sparc64" book I stumble
on the following error while building glibc:
>From configure:
(...nothing suspicious before...)
checking for long double... no
checking size of long double... 0
running configure fragment for sysdeps/sparc/sparc64/elf
checking for sparc64 TLS support... no
checking for sparc64 ld WDISP22 handling... ok
running configure fragment for libidn/sysdeps/unix
running configure fragment for nptl/sysdeps/unix/sysv/linux
running configure fragment for nptl/sysdeps/pthread
checking for forced unwind support... (cached) yes
checking for C cleanup handling... (cached) yes
running configure fragment for sysdeps/pthread
(...nothing suspicious here neither...)
Then make aborts with
In file included from include/tls.h:6,
from <stdin>:1:
nptl/sysdeps/sparc/tls.h:59:3: error: #error "TLS support is
required."
make[1]: *** [/mnt/LFS-6/build/glibc-build/Versions.v.i] Error 1
make[1]: Leaving directory `/mnt/LFS-6/build/glibc-20050926'
make: *** [all] Error 2
The reason seems to be that the crt1.o file is not found by the linker
while running the test fragment.
I can work around this by forcing tls support in the config.cache file:
libc_cv_sparc64_tls=yes
Then configure goes like this:
(...)
running configure fragment for sysdeps/sparc/sparc64/elf
checking for sparc64 TLS support... (cached) yes
checking for sparc64 ld WDISP22 handling... ok
(...)
And then the build completes without error.
Is this the way to go ?
