How can I set up a pbuilder with that compiler ? gcc 5 is in experimental, so I guess it should be the experimental chroot but with forced gcc 4:5 there are various ways I guess to achieve it, but here is a fully scripted one ;) mkdir -p /tmp/exp-hooks; echo -ne '#!/bin/sh\nget install -t experimental gcc g++\n' >| /tmp/exp-hooks/E0expgcc; chmod +x /tmp/exp-hooks/E0expgcc sudo pbuilder --create --mirror http://http.debian.net/debian --distribution experimental --hookdir /tmp/exp-hooks NB might want to dump it to some other than base.tgz file > 2. Is there a wiki page somewhere listing the most frequent issue ? FWIW -- some of them seems to be due to internal problems with gcc package(s) as far as I see it, e.g. in scipy gfortran:f77: scipy/fftpack/src/dfftpack/zffti.f x86_64-linux-gnu-gcc-ar: adding 23 object files to build/temp.linux-x86_64-2.7/libdfftpack.a sh: 1: x86_64-linux-gnu-gcc-ar: not found error: Command "x86_64-linux-gnu-gcc-ar rc build/temp.linux-x86_64-2.7/libdfftpack.a build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dffti.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dsinqi.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dffti1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dsinqb.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/zffti1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dcosqi.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dcosqb.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dcosti.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/zfftb.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dsint.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dcosqf.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dfftf.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dfftf1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dsinqf.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dfftb1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dsint1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/zfftf1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dfftb.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dcost.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/zfftf.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/zfftb1.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/dsinti.o build/temp.linux-x86_64-2.7/scipy/fftpack/src/dfftpack/zffti.o" failed with exit status 127sh: 1: x86_64-linux-gnu-gcc-ar: not found so it might be first worthwhile clarifying with Matthias: - aren't those really just have to do with internal gcc package issue and mass bug filing was a bit undue? - is there a page summarizing gcc 5 issue so they could be efficiently tackled? -- Yaroslav O.
