Bug 307233 – dev-scheme/guile-1.8.5-r1 build fails on ppc/ppc64 with CFLAGS=-O2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Stephen Lewis 2010-02-28 21:53:37 UTC]

dev-scheme/guile-1.8.5-r1 is marked stable for ppc64 but will not compile with CFLAGS=-O2 because the stack direction detection code in configure.in is unreliable
It DOES emerge and build with CFLAGS=-O
the unreliable code has now been removed upstream and is not present in 1.8.7
dev-scheme/guile-1.8.7 is marked unstable but DOES emerge, build and run on ppc64 with CFLAGS=-O2

Reproducible: Always

Steps to Reproduce:
1.set CFLAGS=-O2 in make.conf
2.emerge guile-1.8.5-r1           # fails
3.set CFLAGS=-O in make.conf
4.emerge guile-1.8.5-r1           # succeeds

5.set CFLAGS=-O2 in make.conf
6.ACCEPT_KEYWORDS="~ppc64" emerge '=guile-1.8.7'      # succeeds




emerge --info guile

I confirm this bug is also reproducible on ppc.

[Comment 2 Mounir Lamouri (volkmar) (RETIRED) 2010-03-08 22:47:34 UTC]

dev-scheme/guile-1.8.6 is now stable for ppc/ppc64. It is fixing this bug.
