I built a new virtual machine (VM) on 2-May-2019 from thenewly-announced GUIX 1.0 release in the
guix-system-install-1.0.0.x86_64-linux.iso
image file. The VM runs on VirtManager (QEMU/KVM) on CentOS 7.
I initially tried to select 3 desktop managers, but later in theinstallation, one of them died and the system could not recover, norcould it boot from the virtual disk. I tried again, choosing onlyxfce as the desktop manager, and that succeeded.
Since them, I've been busy trying to understand the GUIX model ofUNIX, and testing software installations with a goal to being able toannounce a TeX Live 2019 port to GUIX 1.0 (I'm part of the TeX Livedevelopment team). My build reports for TeX Live appear here:
http://www.math.utah.edu/pub/texlive-utah-2019/
On GUIX 1.0, I found that I could take arbitrary GNU packages (andmany of my own) and invoke the usual commands
tar xf FOO-x.y.z.tar.gz cd FOO-x.y.z ./configure && make all check && make install
AS LONG AS I am logged in on a terminal window via ssh from anothersystem.
However, if I instead execute those commands remotely with
% ssh guix10.vm.example.com 'cd FOO-x.y.z ; ./configure && make all check && make install'
then the configure script fails like this:
checking whether the C compiler works... no configure: error: in `/local/build/cc/dw-2.00': configure: error: C compiler cannot create executables See `config.log' for more details ...
The config.log file contains these messages:
ld: cannot find crt1.o: No such file or directory ld: cannot find crti.o: No such file or directory collect2: error: ld returned 1 exit status
In separate experiments, I verified that my shell enviroment (asreported by "env | sort") was the same in both cases.
I then installed the strace package and ran
% ssh guix10.vm.example.com 'cd FOO-x.y.z ; strace -f -o foo.strace ./configure'
That identified the problem:
% fgrep crt1.o foo.strace | grep 'lib.*crt' ... 28734 access("/gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/libcrt1.o", R_OK) = -1 ENOENT (No such file or directory)
There is a missing path separator in the word "libcrt1.o"; the correctfile is this one:
$ ls -l /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/crt1.o -r--r--r-- 2 root root 2024 Dec 31 1969 /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/crt1.o
The bad pathname may be generated by GUIX's ld, but it is unclear tome why it works in an interactive login, but fails as shown in an sshbatch command execution.
Until this problem is fixed, I cannot incorporate GUIX in my massivebuild farm testing on 250+ flavors of Unix that I routinely do formany GNU, and other, packages.

You need to install the ‘gcc-toolchain’ package, not just ‘gcc’:

I hope this helps!
Thanks for testing,Ludo’.

What does ‘config.log’ show?
What does ‘guix package --list-installed’ return?
Please make sure that only ‘gcc-toolchain’ is in your profile, and not ‘gcc’.

The config.log fragment is
	configure:2095: gcc  -I${prefix}/include  -I${prefix}/include -L/usr/uumath/lib64 -Wl,-rpath,/usr/uumath/lib64 conftest.c  >&5	ld: cannot find crt1.o: No such file or directory	ld: cannot find crti.o: No such file or directory	collect2: error: ld returned 1 exit status
I tried
	guix remove gcc
Same problem.  I then did
	guix remove gcc-toolchain
Same problem: there is still a gcc visible: /u/sy/beebe/.guix-profile/bin/gcc.
The strace output shows that it tries to load .../libcrt1.o, instead of .../lib/crt1.o.
Here is what I find about installed gcc-related packages:
	$ guix package --list-installed |grep gcc	gccgo   4.9.4   out     /gnu/store/7108fl31hfj9lb4y76g89sxdb43c1wpc-gccgo-4.9.4	gcc-objc        8.3.0   out     /gnu/store/44r4xl10nmix25bv6bv974r280vc232c-gcc-objc-8.3.0	gcc-objc++      8.3.0   out     /gnu/store/wqycqqp4almqcmmsj7gys56lyk9girvq-gcc-objc++-8.3.0	gcc-bootstrap   0       out     /gnu/store/fgarfy5392vz5hik1ag5b8ccv0r4cm01-gcc-bootstrap-0	gcc-toolchain   9.1.0   out     /gnu/store/aqv6njg05w2yqh8krgrjy0wcbfxb4nn3-gcc-toolchain-9.1.0
Maybe it is related to another problem that I wanted to eventuallyraise on a guix list.  Namely, after installing the new GUIX 1.0 VM, Ifound that /usr/bin, /usr/sbin, and /sbin do not exist, and /bincontains only /bin/sh.  Even after numerous "guix install" runs, /bincontinues to have only one entry.
This seems bizarre, because it is long-standing practice thatshell scripts should set PATH to a limited value to avoidtrojan attacks, and things like "/bin/rm foo" should always work.
On your GUIX systems, do you have a reasonably populated /bin?  Dittothe other three.

It’s crowded here. Please remove everything but ‘gcc-toolchain’.
Now, if you want to have Objective-C support, you of course have toinstall ‘gcc-objc’ and/or ‘gcc-objc++’. However, you’ll have to makesure that they come after ‘gcc-toolchain’ in your profile, like so:
guix install gcc-toolchain gcc-objc

Correct.

The GNU build system purposefully makes no assumptions on the locationof tools: ‘configure.ac’ files have AC_PROG_SED, AC_PATH_PROG, andsimilar calls.

No. By default, one gets /bin/sh, and nothing more.
This is a radical departure from Unix tradition, but (1) GNU’s Not Unix;-), and (2) the lack of a global name space gives rise to manyinteresting properties: transactional upgrades and rollbacks are nowpossible, per-user profiles, on-the-fly environments with ‘guixenvironment’, etc.

Note that this is bogus, due tohttps://issues.guix.gnu.org/issue/35541, which will be fixed inGuix 1.0.1 in the coming days.
You should write:
(packages (append (list (specification->package "nss-certs")) %base-packages))
to get the full set of “base packages” (Coreutils, grep, etc.) in $PATHby default.
Once you’ve made that change, you have to reconfigure your system:
guix system reconfigure /etc/config.scm
HTH!

% sudo -s # guix system reconfigure /etc/config.scm # reboot
Even after that major update, and reboot, I still find that, from aremote ssh connection, configure fails to find a C compiler, becauseof the faulty construction of the path to crt1.o.
Can you folks reproduce that behavior at your end with the simple testbundle that I put up at
http://www.math.utah.edu/~beebe/guix-bug.tar.gz
?

I cannot reproduce the problem. With ‘guix environment’, as show below,I build an isolated environment that contains nothing but‘gcc-toolchain’ and Bash:

Toggle snippet (6 lines)

$ guix environment --ad-hoc -C gcc-toolchain[env]$ echo 'int main() { }' > t.c[env]$ gcc t.c[env]$ ./a.out

As you can see, I can compile and link in that environment.
This environment defines PATH, CPATH, and LIBRARY_PATH appropriately:

Toggle snippet (7 lines)

$ guix environment --ad-hoc -C gcc-toolchain grep coreutils[env]$ env | grep PATHCPATH=/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/includeLIBRARY_PATH=/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/libPATH=/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/bin:/gnu/store/26ng85mn5rs22cw654bvh62wh0yjx89h-profile/sbin

Can you check the value of CPATH and LIBRARY_PATH in your user shell?
What does ‘guix package --search-paths’ return?

Nelson please inspect the output you remotely get from:
remote-machine$ ssh guix10.vm.example.com 'env'
compare it with the one you locally get from:
guix10.vm.example.com$ env
and compare it with the one you remotely get from
remote-machine$ ssh guix10.vm.example.com 'bash -l -c "env"'
(the part before the $ prompt is a fictional hostname)
User environment - essential for Guix to work - is not passed(permitted) usually by default via ssh; the easiest option is to wrapyour command in a remote login shell invocation; in your case should be:
remote-machine$ ssh guix10.vm.example.com 'bash -l -c "cd FOO-x.y.z ; ./configure && make all check && make install"'

Earlier you wrote this
there is still a gcc visible: /u/sy/beebe/.guix-profile/bin/gcc.
Where does that come from? Are you activating this profile in someshell initialisation file? Does that profile contain “gcc-toolchain” or“gcc”?
What does PATH look like?
You can check with “guix package -p /u/sy/beebe/.guix-profile -l”.
(Or is $HOME equivalent to /u/sy/beebe on this system and the profile isthus the default?)
I’m interested in the activation of that profile. We recommend addingthese lines to ~/.bash_profile (not .bashrc) in the manual:
export GUIX_PROFILE=$HOME/.guix-profile source $GUIX_PROFILE/etc/profile
(Leaving out the definition of GUIX_PROFILE will change the behaviourslightly and you would end up with potentially outdated absolute storefile names in your PATH.)
