Hi Guix Devel, I am (again) having (new) test suite failures while building guix version 0.10.0 on Cent0S-7 and would appreciate your help. I am building and testing as follows: env -i PATH=${PATH} bash ## build in a clean shell bld=$(mktemp -d) ## in a clean, new, empty directory cd $bld git clone git://git.savannah.gnu.org/guix.git --branch v0.10.0 guix@v0.10.0 cd guix@v0.10.0 mkdir LOGS ## this is where I'll put logs of each build step ./bootstrap |& tee LOGS/boostrap.log pfx=${bld}/pfx ## use a bogus prefix while testing the build process ./configure --prefix=${pfx} |& tee LOGS/configure.log make -j20 |& tee LOGS/make.log make -j20 check |& tee LOGS/make.check.log I interrupted the check after "PASS: tests/guix-build.sh" as it seemed hung (top showed no activity) The failed logs are attached. They are: tests/builders.log tests/guix-lint.log tests/guix-package-net.log tests/packages.log tests/guix-system.log tests/guix-environment.log In case it helps, searching them for 'error:' finds: tests/builders.log:configure: error: in `/tmp/guix-build-make-boot0-4.1.drv-0/make-4.1': tests/builders.log:configure: error: C compiler cannot create executables tests/guix-lint.log:ERROR: In procedure string-append: tests/guix-lint.log:ERROR: In procedure string-append: Wrong type (expecting string): #f' tests/guix-package-net.log:configure: error: in `/tmp/guix-build-make-boot0-4.1.drv-0/make-4.1': tests/guix-package-net.log:configure: error: C compiler cannot create executables tests/guix-package-net.log:guix build: error: build failed: build of `/tmp/tmp.zs1boPbszS/guix@v0.10.0/test-tmp/store/dz6qqb4qpad02qigvwavyha3ysprsary-make-boot0-4.1.drv' failed tests/packages.log:configure: error: in `/tmp/guix-build-make-boot0-4.1.drv-0/make-4.1': tests/packages.log:configure: error: C compiler cannot create executables tests/packages.log:error: this-package-does-not-exist: unknown package tests/guix-system.log:t-guix-system-26203:2:3: error: missing field initializers (bootloader host-name file-systems timezone) tests/guix-system.log:guix system: error: service 'networking' provided more than once tests/guix-system.log:guix system: error: service 'buggy!' requires 'does-not-exist', which is undefined tests/guix-system.log:guix system: error: build failed: invalid character `@' in name `shepherd-file-system--tmp-tmp.zs1boPbszS-guix@v0.10.0-test-tmp-store.scm-builder' tests/guix-environment.log:configure: error: in `/tmp/guix-build-make-boot0-4.1.drv-0/make-4.1': tests/guix-environment.log:configure: error: C compiler cannot create executables tests/guix-environment.log:guix environment: error: build failed: build of `/tmp/tmp.zs1boPbszS/guix@v0.10.0/test-tmp/store/8xxwc0pws1aq6jj5a91xwsbvrwbf0m1c-profile.drv' failed Also attached are all my LOG/*.log files if it helps If there is any better info I can provide to help in diagnosing, please advise.
