Bug 839888 – app-emulation/xen-4.16.2_pre2 calls cc directly

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Agostino Sarubbo 2022-04-21 10:50:17 UTC]

Issue: app-emulation/xen-4.16.0-r6 calls cc directly.
Discovered on: amd64 (internal ref: ci)

NOTE:
As per QA policy, toolchain tools must not be called directly because they can cause issue in cross-compiling and because is not possible use a different CC implementation (like clang). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks].

Error(s) that match a know pattern:


/bin/sh: line 1: gcc: command not found
make[1]: *** No rule to make target 'FATAL'.  Stop.

    app-emulation/xen: provide clang=(y|n), HOSTCC and HOSTCXX to make
    
    Provide clang=(y|n) to the make invocation as it tells Xen's build
    system whether or not clang is used. Also set HOSTCC and HOSTCXX. I
    believe this to probably fix calling cc directly (bug #839888).
    
    Also set LDFLAGS correctly. Previously LDFLAGS would be unset, which
    made raw-ldflags return the empty string, so
    
       # Send raw LDFLAGS so that --as-needed works
       LDFLAGS="$(raw-ldflags)"
    
    set LDFLAGS to the empty string.
    
    Finally, no longer unset ASFLAGS, as the ASFLAGS environment variable is
    no longer used by Xen.
