i've tested various versions on the pi4 (no crossdev)

cmake-3.16.5
cmake-3.17.4-r1

They all fail while linking libCTestLib.a

Any clues ?

blubberbaer,

Please put the entire log onto a pastebin site. That "Error 2" suggests that the real problem is further up the log. grep the log for "Error 1".

If it helps any my arm64 binhost has cmake-3.18.4 and cmake-3.19.0.
Feel free to help yourself.

I'll try dev-util/cmake-3.16.5. .... dev-util/cmake-3.16.5 builds for me. Trying 3.17.4-r1 now.

-- edit --
Both built and added to the binhost. We need to see your build log.

-- edit again --

Wild guess. 4G RAM ... MAKEOPTS="-j4 ... and C++.
You ran out of RAM and the OOM kicked in and killed one of your make threads.

Dear NeddySeagoon,

i had to split up the build.log in a few smaller files. Sorry for that:

this time i tried cmake-3.18.3 to build but it didn't work out

Post by **NeddySeagoon** » Thu Nov 26, 2020 9:58 pm

blubberbaer,

Its a linker error. I'm using the ~arm64 binutils, which is the package that provides the linker. You may want to try that.

binutils is slotted. The testing binutils will be an addition to your stable binutils.
You must use binutils-conf to choose the new binutils before it will be used.

Code: Select all

$ binutils-config -l
 [1] aarch64-unknown-linux-gnu-2.34

Dear all,

i've tried a few things to get rid of linking problem.

1) did as NeddySeagoon told me ...

update of binutils to binutils unstable (sys-devel/binutils-2.35.1-r1) .... didn't help ;-(

2) recompiled libuv.so

didn't help

3) switched to CFLAGS

-march=armv8-a+crc -mtune=cortex-a72 -ftree-vectorize -O2 -pipe

after that emerge -e system

didn't help

4) switched to aarch64-unknown-linux-gnu-10.2.0

didn't help but ..... the error out in the build.logs changed a bit ...

blubberbaer,

What does eix cmake say?

     Homepage:            https://cmake.org/
     Description:         Cross platform Make

It builds here with USE="doc ncurses qt5 -emacs -test"

You have

Code: Select all

Package:    dev-util/cmake-3.18.3
Repository: myrepo
USE:        arm64 elibc_glibc kernel_linux ncurses userland_GNU

That raises a few eyebrowns. Repository: myrepo ... whats wrong with the gentoo cmake. That's what I use.

You only have USE=ncurses but I don't think is USE flag related.

Please try the in tree cmake.

Dear NeddySeagoon,

thanks for your reply. I have another rpi4 (sakaki image). Since cmake-3.18.3 was already removed from the tree I've copied the ebuild to my new non-sakaki gentoo rpi4. I hoped it would build. But it didn't. Anyway, i've tried with cmake-3.19.1 from the tree:

eix:

 - - emacs   : Add support for GNU Emacs

 - - qt5     : Add support for the Qt 5 application and UI framework
 - - test    : Enable dependencies and/or preparations necessary to run tests (usually
               controlled by FEATURES=test but can be toggled independently)

I've added +doc. +qt5 gave a circular dependencies

It might be possible to break this cycle
by applying the following change:
- dev-util/cmake-3.19.1 (Change USE: -qt5)

The build log of cmake-3.19.1 shows the same failure

Perhaps it is a libgcc problem (see build.log) because aarch64_cas4_acq_rel is a hidden symbol ?

Have a nice day,

blubberbaer,

It build for me on two different arm64 systems, both configured to produce Pi4 optimised code, so I'm at a bit of a loss.
I've not actually tried the build on a Pi yet though. That's my next step.

ebuilds are never gone. The current tree is in git. All the ebuilds since the change from CVS (2015?) can be recovered.
ebuilds that were in CVS are online too, back to the start of CVS in 2000. Almost the dawn of Gentoo.

If you want to ask in #gentoo-arm on freenode, I think the arm team will be interested.
You will need a registered nick to speak.

I don't think its a systematic problem or it would hit everyone, not just you. So far, this is the only report of the problem that I know of

-- edit more --

cmake-3.19.0 builds on an 8G Pi4 here with MAKEOPTS="-j5"

Dear Neddy Seagoon,

thanks. I will ask at #gentoo-arm.

Did another try. This time

compiler: aarch64-unknown-linux-gnu-8.4.0
MAKEPOPTS="-j1" emerge -u cmake
binutils: aarch64-unknown-linux-gnu-2.35.1

;-( still the same ...

now trying

compiler: aarch64-unknown-linux-gnu-10.2.0
MAKEPOPTS="-j1" emerge -u cmake
binutils: aarch64-unknown-linux-gnu-2.35.1

Many thanks anyway ....

Many thanks to #gentoo-arm .....

Here are the instructions they gave to me :

1) Change CFLAGS in make.conf back to standard stuff. If i remember right, those are the default settings if you follow
https://wiki.gentoo.org/wiki/Raspberry_ ... it_Install

make.conf

Code: Select all

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
COMMON_FLAGS="-O2 -pipe"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult https://wiki.gentoo.org/wiki/Changing_the_CHOST_variable before changing.
CHOST="aarch64-unknown-linux-gnu"

Having a peek at the genpi64 make.conf i switched them to #COMMON_FLAGS="-march=armv8-a+crc -mtune=cortex-a72 -ftree-vectorize -O2 -pipe" in between, that did not to work out

2) emerge -v1 libuv

since libuv failed on being linked with the rest, it should be rebuild

3) emerge -v1 cmake

Have fun,

blubberbaer

I have exactly same problem on my PC mashine arm64 with 12G memory and 6 core AMD, and i am forced to compile cmake by hand, because only that option works. And installing it by hand. I do it now from almost 1 year.
My system was updated few times, and problem with CMAKE was still this same.
My common flags looks like this

Code: Select all

#COMMON_FLAGS="-march=native -O2 -pipe -fomit-frame-pointer"
#COMMON_FLAGS="-O2 -pipe "
COMMON_FLAGS="-O2 -pipe -march=native"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"
CHOST="x86_64-pc-linux-gnu"
#CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX:PATH=~/local"

changing to proposed

Code: Select all

COMMON_FLAGS="-O2 -pipe "

did not hep, still I get that error.[/quote]

Code: Select all

[ 99%] Built target CTestLib
make[1]: Leaving directory '/var/tmp/portage/dev-util/cmake-3.23.3/work/cmake-3.23.3_build'

I did try reuse CMAKE_EXTRA_FLAGS because in the past I did put that line in make file for some reason, I don't remember why, but I have.
also without success.
Then I start playing with cmake flags

Code: Select all

sudo USE="qt5 ncurses -static-libs"  emerge -av1 cmake

also did not work. I am thinking if " test " flag have something to do.
Full requirement of cmake use flag looks like this

Code: Select all

dev-util/cmake-3.23.3 -ncurses -qt5 -doc -emacs -test -verify-sig -examples -java static-libs

end emerge is showing me that

Code: Select all

dev-util/cmake-3.23.3:0/0::gentoo [3.22.4:0/3.1::gentoo] USE="ncurses%* -doc% -emacs% -qt5% -test% -verify-sig% (-examples%) (-java%*) (-static-libs%)"

If I try use test flag then emerge shows me

Code: Select all

[ebuild   R    ] app-arch/libarchive-3.6.1:0/13::gentoo  USE="acl bzip2 e2fsprogs iconv lzma lzo xattr zstd* -blake2 -expat -lz4 -nettle -static-libs -verify-sig" ABI_X86="32 (64) (-x32)" 0 KiB
[ebuild  N     ] x11-apps/xhost-1.0.8::gentoo  USE="ipv6" 136 KiB
[ebuild   R    ] x11-base/xorg-server-21.1.4:0/21.1.4::gentoo  USE="systemd test* udev xorg xvfb* -debug (-elogind) -minimal (-selinux) -suid -unwind -xcsecurity -xephyr -xnest" 0 KiB
[ebuild     U  ] dev-util/cmake-3.23.3:0/0::gentoo [3.22.4:0/3.1::gentoo] USE="ncurses%* test%* -doc% -emacs% -qt5% -verify-sig% (-examples%) (-java%*) (-static-libs%)" 0 KiB

Total: 4 packages (1 upgrade, 1 new, 2 reinstalls), Size of downloads: 136 KiB

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by dev-util/cmake-3.23.3::gentoo[test]
# required by cmake (argument)
>=app-arch/libarchive-3.6.1 zstd
# required by dev-util/cmake-3.23.3::gentoo[test]
# required by cmake (argument)
>=x11-base/xorg-server-21.1.4 xvfb

But When I try compile I get error

Code: Select all

!!! All ebuilds that could satisfy "app-arch/libarchive[zstd]" have been masked.
!!! One of the following masked packages is required to complete your request:
- app-arch/libarchive-3.6.1::gentoo (masked by: )

But this package when I am compiling by hand, it works without problems.

and after recompiling all packages needed for cmake " test " flag, and compile cmake it self with that flag, again this same problem.

Code: Select all

/usr/bin/x86_64-pc-linux-gnu-ranlib libCTestLib.a

looks like something is wrong with compatibility with emerge setting compiling process, because compile cmake by hand works with no errors using package downloaded in partage temp directory.

And now, when I am updating @world, or compiling package witch use cmake in tree, I need exclude that package from recompiling.

And still I dont have idea how to solve that problem.
