Doc Text:	Previously, the "devtoolset-7-gcc" package did not contain a symbolic link to the objcopy utility installed by the "devtoolset-7-binutils" package. As a consequence, GCC from Red Hat Developer Toolset used the system version of objcopy which lacked some features, such as the `-gsplit-dwarf` option. The symbolic link has been added and the correct version of objcopy is now used.	Story Points:	---

Description Piyush Bhoot 2017-10-12 12:28:12 UTC

Description of problem:
Need a link to objcopy to better support split dwarf
The RH Developer Toolset is missing a symbolic link necessary for seamless use of the relatively new Split Dwarf (or DebugFission) feature.


In particular, there should be an objcopy symbolic link in:
/opt/rh/devtoolset-6/root/usr/libexec/gcc/x86_64-redhat-linux/6.2.1

Pointing to:
../../../../bin/objcopy

If you look in /opt/rh/devtoolset-6/root/usr/libexec/gcc/x86_64-redhat-linux/6.2.1, you will see symbolic links for other compiler-needed binutils tools such as ar, as, ld, nm, ranlib, strip.  For –gsplit-dwarf to work, the compiler also needs the matching version of objcopy.


Version-Release number of selected component (if applicable):
devtoolset-6-binutils-2.27-12.el7.1.x86_64

How reproducible:
Always

Steps to Reproduce:

ls -l devtoolset-6/root/usr/libexec/gcc/x86_64-redhat-linux/6.2.1 | grep bin
 	ar -> lrwxrwxrwx 1 root root       18 Apr 27 15:26 ar -> ../../../../bin/ar
	as ->lrwxrwxrwx 1 root root       18 Apr 27 15:26 as -> ../../../../bin/as
	ld ->lrwxrwxrwx 1 root root       18 Apr 27 15:26 ld -> ../../../../bin/ld
	ld.bdf->lrwxrwxrwx 1 root root       22 Apr 27 15:26 ld.bfd -> ../../../../bin/ld.bfd
	ld.gold->lrwxrwxrwx 1 root root       23 Apr 27 15:26 ld.gold -> ../../../../bin/ld.gold
	nm->lrwxrwxrwx 1 root root       18 Apr 27 15:26 nm -> ../../../../bin/nm

link for objcopy is missing

Additional info:

Comment 4 Nick Clifton 2018-01-09 16:33:53 UTC

Reassigning to gcc, as the symlinks are actually constructed by the %install phase of the gcc.spec file.

Comment 5 Marek Polacek 2018-01-09 19:29:56 UTC

Fixed in git.

Comment 8 Michael Petlan 2018-04-26 22:31:37 UTC

Tested with devtoolset-7-gcc-7.3.1-5.4. It has the requested symlink.
VERIFIED.
