Dear All, I seem to be having problems with the installation of an image processing application called ITK-SNAP [0, 1]. This is the error message I get: $ guix environment --pure --ad-hoc itk-snap The following derivations will be built: /gnu/store/qx7cx3gjqc709gla302yyaggbihq9kw0-itk-snap-3.8.0.drv /gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv building /gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv... | 'configure' phasebuilder for `/gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv' failed with exit code 1 build of /gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv failed View build log at '/var/log/guix/drvs/r3/ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv.bz2'. cannot build derivation `/gnu/store/qx7cx3gjqc709gla302yyaggbihq9kw0-itk-snap-3.8.0.drv': 1 dependencies couldn't be built guix environment: error: build of `/gnu/store/qx7cx3gjqc709gla302yyaggbihq9kw0-itk-snap-3.8.0.drv' failed If I understand it correctly, this seems to indicate an underlying problem with vtk-6. As a matter of fact, this also fails: $ guix environment --pure --ad-hoc vtk@6.3.0 The following derivation will be built: /gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv building /gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv... - 'configure' phasebuilder for `/gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv' failed with exit code 1 build of /gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv failed View build log at '/var/log/guix/drvs/r3/ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv.bz2'. guix environment: error: build of `/gnu/store/r3ndf5r2ck8n5h5sq4phipdvgmv5bagg-vtk-6.3.0.drv' failed The output of the following command is attached. $ bzcat /var/log/guix/drvs/r3/ndf5r2ck8n5h5sq4phipdvgmv5bagg\ -vtk-6.3.0.drv.bz2 | tail -n 50 Interestingly, a more recent version of vtk seems to install just fine. $ guix environment --pure --ad-hoc vtk [this works as expected] It may be worth to mention that I'm running Guix on a foreign distribution. This is how my guix self-describes itself: $ guix describe guix 8dcbd8a repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: 8dcbd8a374f21f478f0059d4d62e364897e6e667 Is there anything you would suggest I could investigate to solve this?
