Hi!
Could you advise the right way to build Glibc2.17 with gcov coverage testing
support?
I couldn't find any working solution on how to do it.
I was trying to add extra CFLAGS="--coverage" (or CFLAGS="-fprofile-arcs
-ftest-coverage") for glibc configuration and build.
The following configuration error occur:
./configure --prefix=/usr --host=arm-none-linux-gnueabi
--enable-add-ons=ports,nptl --without-fp ...
checking whether to put _rtld_local into .sdata section... no checking for
.preinit_array/.init_array/.fini_array support... no
configure: error: Need linker with .init_array/.fini_array support.
Hence I can successfully build Glibc without mentioned CFLAGS.
The second solution I've tried was configuring Glibc without extra CFLAGS
and adding these CFLAGS on make stage only.
Make stage failed with the following error:
arm-none-linux-gnueabi-gcc -nostdlib -nostartfiles -r -o

There are no --enable-coverage or --enable-gcov options for Glibc
configuration.
