Bug 43008 – With gnupg-1.2.4, on sun4m (SS20, SS10, SS5), the '-mcpu=v8' CFLAG should be downgraded to '-mcpu=v7'

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ferris McCormick (RETIRED) 2004-02-26 11:12:39 UTC]

gnupg-1.2.4 will not build on all sun4m (SS20 & friends) systems if the CFLAG
'-mcpu=v8' is set because the 'make check' portion fails like this:
===========
./gpg_dearmor > ./pubring.pkr < ./pubring.pkr.asc
./gpg_dearmor > ./secring.skr < ./secring.skr.asc
../g10/gpg --homedir . --quiet --yes --no-permission-warning --import ./pubdemo.asc      
gpg: key 68697734: no valid user IDs
gpg: key 1AFDAB6C: no valid user IDs
gpg: key FAEF6D1B: no valid user IDs
gpg: key 8FC282E6: no valid user IDs
==================
and so on.  If you do
CFLAGS="-mcpu=v7 -mtune=v8 -O2 -pipe" emerge gnupg
everything builds and installs fine.

On sun4u (Ultra 60 etc) with '-mcpu=ultrasparc' everything is fine.

So, the problem is sun4m+-mcpu=v8 specific, and perhaps local to my particular
system, but I cannon verify that.

Reproducible: Always
Steps to Reproduce:
1.CFLAGS="-mcpu=v8 -O2 -pipe" emerge -uv gnupg  (for failure on sun4m)
2.CFLAGS="-mcpu=v7 -O2 -pipe -mtune=v8" emerge -uv gnupg (for success on sun4m)
3.

Actual Results:  
In the first case, the build fails as noted above.  In the second case, it
succeeds.

Expected Results:  
Upgrade gnupg in both cases.

Kernel is 2.4.21-r1 because it is known to work for sun4m-SMP.  Problem could be
kernel related.

Actually we had adjusted the gnupg-1.2.3 ebuilds to fix this, but the syntax of filter-flags slightly changed so it wasn't doing the right thing anymore.  I've adjusted the ebuild and it should be fine now.
