Hello,
With `-O0', the Hurd fails to cross-build:
#v+
i586-pc-gnu-gcc
-Wl,-rpath-link=.:../libtrivfs/:../libports/:../libihash/:../libps/:../libpipe/:../libiohelp/:../libpager/:../libdiskfs/:../libftpconn/:../libnetfs/:../libcons/:../libstore/:../libshouldbeinlibc/:../libfshelp/:../libthreads/:../libhurdbugaddr/
-O0 -g -std=gnu99 -fgnu89-inline -Wall -g -O3 -O0 -g -std=gnu99
-fgnu89-inline -Wall -g -O3 -O0 -g -uargp_program_bug_address -o auth \
auth.o authServer.o auth_replyUser.o \
'-Wl,-(' ../libhurdbugaddr/libhurdbugaddr.so ../libthreads/libthreads.so
../libports/libports.so ../libihash/libihash.so
../libshouldbeinlibc/libshouldbeinlibc.so \
\
'-Wl,-)'
../libthreads/libthreads.so: undefined reference to
`__hurd_threadvar_location'
collect2: ld returned 1 exit status
make[1]: *** [auth] Error 1
#v-
The problem doesn't occur at `-O1' and above.
This is with:
- Hurd ffd73488f9eecdb9da40e15f5fdcebf392cb88f8
- Glibc from Savannah's hurd/glibc.git, branch `tschwinge/Roger_Whittaker',
glibc-2.11-1140-ge6d0540
- GCC 4.5.1, set to cross-build from GNU/Linux.
Thanks,
Ludo'.
