Description

Just encountered this in my macOS 10.9 VM. Looks like it's also failing for the 10.8 and 10.9 buildbots, as well:

cipher-gcm-intel-pclmul.c:400:33: error: cannot compile this unexpected cast lvalue yet
                : [pconst] "m" (pconst),

I was afraid this might happen with an old OS version.

However, --disable-asm was a blocker on all modern OS versions.

Can we simply make the compiler blacklist more restrictive?

comment:3 Changed 3 years ago by Schamschula (Marius Schamschula)

Try adding

if {${os.platform} eq "darwin" && ${os.major} < 14} {
    configure.args  --disable-asm
}

After including the compiler blacklist PG, our usual go-to worked: clang < 900.

Do we really want to disable assembly code...?

comment:5 Changed 3 years ago by Schamschula (Marius Schamschula)

The error

error: cannot compile this unexpected cast lvalue yet

is a clang issue, so it has nothing to do with --disable-asm

Looking at the Portfile notes:

    # libgcrypt-1.5.0 does some ugly stuff with their udiv_qrnnd macro in mpih-div.c
    # error: invalid use of a cast in a inline asm context requiring an l-value: remove the cast
    configure.cflags-append "-fheinous-gnu-extensions"

no longer seems to work.

Adding

    compiler.blacklist-append {clang < 900}

to the if {[string match "*clang*" ${configure.compiler}]} { block might do the trick.

Marius, don't you need to add the compiler_blacklist_versions portgroup...?

comment:12 Changed 3 years ago by mascguy (Christopher Nielsen)

Fix requires addition of said portgroup, reopening ticket.

comment:14 Changed 3 years ago by Schamschula (Marius Schamschula)

True enough. I lifted the fix from another of my Portfiles and forgot to add the PG.
