Description Siddhesh Poyarekar 2021-12-08 03:24:19 UTC 
When building i686-gnu with build-many-glibcs.py and this patch[1] (with the hunk changing sysdeps/mach/hurd removed) to enable PIE across the board in glibc, the Hurd target fails as follows:

build-many-2/install/compilers/i686-gnu/lib/gcc/i686-glibc-gnu/11.2.1/../../../../i686-glibc-gnu/bin/ld: cannot find build-many-2/build/glibcs/i686-gnu/glibc/csu/rcrt0.o: No such file or directory
collect2: error: ld returned 1 exit status
make[3]: *** [../Rules:269: build-many-2/build/glibcs/i686-gnu/glibc/support/test-run-command] Error 1

This prevents PIE from being enabled by default for hurd.  I'll post the final link of the commit and clearer steps to reproduce when it actually goes in.

This is fixed by 556a6126f8764bc66d03368b5ac3e26631556559
Comment 2 Siddhesh Poyarekar 2021-12-14 02:49:30 UTC 
Thanks, could you please remove definition of PIE_UNSUPPORTED in sysdeps/mach/hurd/configure.ac so that PIE is enabled on hurd?

yep, done so!
