Description Nathan Whitehorn freebsd_committer 2017-12-09 22:56:42 UTC
Created attachment 188675 [details]

The attached patch fixes the build of the base/ ports and ports-mgmt/pkg via cross-build on systems without QEMU userland support.

It does the following:
- Set C*_FOR_BUILD variables that various GNU tools need for their native compiler in autoconf.
- Set CPPFLAGS to include the sysroot flags so that code using the preprocessor by itself also gets the right headers. This fixes GCC's autoconf checks that override autoconf's AC_GET_HEADER macros to use cpp directly rather than the compiler.
- Have a cross-built pkg(8) use the native system pkg to package itself rather than the new cross-built pkg, which of course is not executable.
- Upgrade GCC to 6.3 from 5.4
- Change the vendor tag on base/gcc from portbld to unknown to fix some brokenness in its internal build system and match the cross-compiler installed by e.g. powerpc64-gcc.
- Repair GCC's build system to pass CPPFLAGS around correctly and avoid conflation of host and build CPPFLAGS, which we require as a result of GCC's broken non-inclusion of -isystem =/usr/include by default unless a cross root is present when building the cross-compiler.
- Repair GCC's build system to set proper C*FLAGS for native tool builds.
Comment 1 Alexander Kabaev freebsd_committer 2017-12-20 13:50:15 UTC
This look sane, will take a closer look at GCC changes on weekend.
Comment 2 Andreas Tobler freebsd_committer 2017-12-20 21:25:17 UTC
Bump gcc at least to 6.4, 6.3 is already EOL.
Comment 3 Alexander Kabaev freebsd_committer 2017-12-24 00:09:03 UTC
I'll update to 6.4 this week
Comment 4 Mark Millard 2018-01-13 23:05:51 UTC
FYI: There are also bugzilla reports:


for base/gcc and base/binutils . Some or all
may be addressed here. These are from back
when I tried to use it and recorded the
work arounds that I used to get the next
stage as I went along.
Comment 5 Nathan Whitehorn freebsd_committer 2018-01-22 23:38:57 UTC
(In reply to Alexander Kabaev from comment #3)

Did you want me to do the update? I was trying to keep this in sync with devel/powerpc64-gcc, which is still 6.3.

Comment 7 Steve Wills freebsd_committer 2018-01-31 18:54:15 UTC
When trying to build world after installing the new packages, I find I have to set COMPILER_TYPE manually and also hit this error:

cc -isystem /usr/obj/usr/src/powerpc.powerpc64/tmp/usr/include -L/usr/obj/usr/src/powerpc.powerpc64/tmp/usr/lib -B/usr/obj/usr/src/powerpc.powerpc64/tmp/usr/lib --sysroot=/usr/obj/usr/src/powerpc.powerpc64/tmp -B/usr/obj/usr/src/powerpc.powerpc64/tmp/usr/bin -shared -nostdlib hack.c -o hack.pico

Sorry, was building kernel and world, that failure was during kernel build.
Comment 9 Mark Millard 2018-01-31 19:07:40 UTC
(In reply to Steve Wills from comment #7)

See bugzilla 214404 for a prior report of such
"collect2: fatal error: cannot find 'ld'" notices.

Although it has been some time, I submitted:


back when I tried the base/ materials. I do not
know how much has been addressed after that.

(In reply to Mark Millard from comment #9)
I have found a way to get it to at least find ld, now it just needs some other help, I'll keep at it and post patches when I have it working.

Updated patch

Here's an updated patch which for me allows the built compiler to generate binaries if I pass -sysroot and -isystem. The OSREL has to be in the --target due to this change:


that was introduced due to this bug report:


When the --target and --host don't match, gcc's configure decides you're building a cross compiler, which we aren't doing here. So unfortunately it seems like the right thing to do is make --target and --host match and to have the OSREL in both for both gcc and binutils.

This change does that and after updating and rebuilding everything I seem to have a working compiler.

Please test and see if this fixes the issues reported in this bug and the other bugs mentioned.
Comment 12 Steve Wills freebsd_committer 2018-02-01 18:12:09 UTC
(In reply to Steve Wills from comment #11)
Correction, passing -sysroot and -isystem is not necessary.
Comment 13 Mark Millard 2018-02-02 05:22:14 UTC
(In reply to Steve Wills from comment #11)

I'm not sure if I'll be able to set up and
test for my old reports this weekend or not.
My time with FreeBSD systems has started to
be greatly constrained in recent times.

If I manage to test, I'll report the results.

# uname -apKU
FreeBSD FBSDFSSD 12.0-CURRENT FreeBSD 12.0-CURRENT  r327485M  amd64 amd64 1200054 1200054

with cross build attempted for targeting powerpc64.

base/binutils did not build once I got needed tools in place.
This stage is tied to the README's:

4/ build the required port
$ cd base/binutils
make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package

(but with powerpc64-gcc and my cross-sysroot path).

Summary of failures:

I had to install devel/bison and devel/gmake to even get
started. devel/powerpc64-xtoolchain-gcc is insufficient.
(I had it installed already.)

It then looked for powerpc64-unknown-freebsd12.0-ar but
no such exists. Instead there is:


which is from:

# pkg which /usr/local/bin/powerpc64-unknown-freebsd12.0-gcc-ar
/usr/local/bin/powerpc64-unknown-freebsd12.0-gcc-ar was installed by package powerpc64-gcc-6.3.0

With that I stopped instead of providing a workaround
this time.

Detail steps/sequence for as far as I got:

I used a pre-existing installworld :


from having built with the system clang and devel/powerpc64-binutils
instead of with gcc 4.2.1 . (I normally experiment with clang
based targeting for powerpc64 and powerpc.)

I reverted /usr/ports/base and then applied the patch. So:

# svnlite status /usr/ports/base | sort
M       /usr/ports/base/gcc/Makefile
M       /usr/ports/base/gcc/distinfo
M       /usr/ports/base/gcc/pkg-plist


# svnlite status /usr/ports/base/
M       /usr/ports/base/binutils/Makefile

?       /usr/ports/base/gcc/files/patch-gcc-configure
M       /usr/ports/base/gcc/pkg-plist

For reference:

# pkg info "powerpc64*"

I then:

# make CROSS_TOOLCHAIN=powerpc64-gcc CROSS_SYSROOT=/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils package

I left RELRO and STATIC unchecked.

The result was:

No go for base/gcc either. . .

I got some more time and attempted base/gcc despite
the base/binutils failure (comments #14 and #15):

# make CROSS_TOOLCHAIN=powerpc64-gcc CROSS_SYSROOT=/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils package

[NOTE: that /usr/local/lib/libintl.so path vs. the later
/wrkdirs/usr/ports/devel/gettext-tools/work/gettext- path.]

It failed building devel/gettext-tools with:

Comment 17 Mark Millard 2018-02-04 02:07:40 UTC
(In reply to Mark Millard from comment #16)

Looks like I should have noted that I already had
a perl in place:

checking for perl... /usr/local/bin/perl

This might go along with devel/bison and devel/gmake
as possibly required --but possibly not automatically
built if missing.

I should have shown that hostname and urlget also got the
pthread_create notice:

--- hostname ---
/wrkdirs/usr/ports/devel/gettext-tools/work/gettext- undefined reference to `pthread_create'
collect2: error: ld returned 1 exit status

make[11]: stopped in /wrkdirs/usr/ports/devel/gettext-tools/work/gettext-

One odd thing that I saw in the output was:
(note the "Unable to load interpreter" and
the long command text but still getting a yes)

checking whether the C++ compiler (/usr/local/bin/powerpc64-unknown-freebsd12.0-g++ -O2 -pipe --sysroot=/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils -isystem /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils/usr/include -DLIBICONV_PLUG -g -fstack-protector -fno-strict-aliasing  --sysroot=/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils -isystem /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils/usr/include -isystem /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils/usr/include/c++/v1 -nostdinc++ -DLIBICONV_PLUG  --sysroot=/usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils -fstack-protector) works... Unable to load interpreter

But its later "checking" that referenced
seemed to go okay.

Note: /wrkdirs is from my /etc/make.conf having:

Comment 18 Mark Millard 2018-02-05 23:32:19 UTC
(In reply to Mark Millard from comment #17)

My results may have been skewed by my forgetting to
revert some forced -unknown- usage in BUTARGET
and BU_PREFIX in the likes of devel/binutils/Makefile
and devel/powerpc64-gcc/Makefile and in
devel/powerpc64-xtoolchain-gcc/files/xtoolchain.mk.in .

I think this was from my earlier attempt at experimenting
with base/binutils and base/gcc .

(In reply to commit-hook from comment #22)

[I got some time to try it: lack of sleep.]

This update worked for me after installing the
following via pkg from my normal poudriere-devel
runs. The README's make commands failed to build
some if they were all missing at the time,
although it tried.


(much like devel/bison and devel/gmake and
lang/perl5.24 were installed first in order
for base/binutils to build). Normal
poudriere-devel builds of these all went fine.

/usr/ports/base/README still makes no mention
of these 7 ports being needed, just mentioning
(for an example *):

pkg install *-xtoolchain-gcc

(in 1/).

Note: I've not done the pkg-plist step or actually
installed what is built.

Is there anything in this patchset that should be submitted upstream
(for GCC 8)?

Probably all the internal GCC build stuff. It would also be *really* nice if we didn't need all the -isystem nonsense when building and the cross-compiler had -I =/usr/include by default when built without a sysroot.

Turns out that a modern devel/powerpc64-binutils
uses powerpc64-unknown-freebsd12.0- prefixes,
just like base/binutils does. The same goes
for devel/powerpc64-gcc and base/gcc .

So base/binutils and devel/powerpc64-binutils
end up with PATH controlling which directory
is used when the path is implicit, just like
base/gcc vs. devel/powerpc64-gcc does.

The above is stated for a powerpc64 context
with both a base/{binutils,gcc} pair installed
and a devel/powerpc64-{binutils,gcc} pair built
and installed. /usr/bin/ vs. /usr/local/bin/
and the like being involved for PATH use when
not explicit.

(I need to be careful of this once I get to the
point of testing base/{binutils,gcc} use in my
powerpc64 context. I normally have
devel/powerpc64-{binutils,gcc} installed and so
could implicitly use the wrong files.)

base/binutils/pkg-plist.sparc64 and
base/binutils/pkg-plist.powerpc64 list:


This appears to imply that the README's sparc64 example lines:

2/ cross build world
make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 buildworld

are intended to be based on (implicitly or
explicitly) WITHOUT_BINUTILS= so that the
files listed are only from base/binutils .
This is likely because the system binutils
are insufficient in some cases for the likes
of, at least, powerpc64.

WITHOUT_BINUTILS= is the default only for arm64/aarch64,
riscv/riscv64, and riscv/riscv64sf according to the
man src.conf that I'm reading.

(It turns out my normal/historical cross-builds include
the system binutils by not having been explicit to avoid
such, both for system-clang based builds and for
powerpc64-xtoolchain-gcc based builds: Not the best way
to test base/binutils use. My test target-context here is:

[I tend to experiment with using system clang for
targeting powerpc64 and powerpc. Thus my context is
odd for what compiler I tend to have around.]

Looks like I also needed to use WITHOUT_CLANG_IS_CC
(or the matching one for gcc for the normal sort of
build context) to avoid overlaps with the
freebsd-gcc-6.3.0.txz content.

I'll note that for WITH_CLANG_IS_CC there is a /usr/bin/CC
script that is installed:

# more /usr/obj/DESTDIRs/clang-powerpc64-installworld_altbinutils/usr/bin/CC
# $FreeBSD: head/usr.bin/clang/clang/CC.sh 292950 2015-12-30 16:14:30Z dim $
# This file is in the public domain.
exec /usr/bin/c++ "$@"

The /wrkdirs/usr/ports/base/gcc/work/pkg/freebsd-gcc-6.3.0.txz
produced in my context for base/gcc does not seem to have such
to put in place:

# tar -tf /wrkdirs/usr/ports/base/gcc/work/pkg/freebsd-gcc-6.3.0.txz | more
. . .
. . .

I do not know if anything needs /usr/bin/CC to be around or not.

Side note:

Panics in fork activity on amd64 have sidelined my progress on the
powerpc64 targeted base/* testing. I'm not likely to get through it
this weekend. Instead the bias is to help identify what head version
is the first to get the panics on amd64 (and possibly others).
