Hi,
I am trying to create a Docker image of Alpine targeting s390x architecture.
Natanael suggested me Timo's previous work at :
http://dev.alpinelinux.org/~tteras/bootstrap/ to bootstrap Alpine on new arch.
I have 2 questions related to this, hope you could shed some light.
Q1:
Running createcross-toolchain.sh, at step 5, building gcc pass 2 : (experimenting with targeting x86)
$ ABUILD_CONF=$ABUILD_CREATECROSS_CONF BOOTSTRAP=nolibc CTARGET_LIBC=musl abuild -r || return 1
(this makes sure --disable-shared is passed to configure script)
Then at step 6, it introduces a conflict between host's gcc and newly installed/built gcc-pass2-$CTARGET
ERROR: unsatisfiable constraints:
gcc-5.3.0-r0:
conflicts: gcc-pass2-i486-alpine-linux-musl-5.2.0-r0[so:libcc1.so.0=0.0.0]
satisfies: g++-5.3.0-r0[gcc=5.3.0-r0] build-base-0.4-r1[gcc]
gcc-pass2-i486-alpine-linux-musl-5.2.0-r0:
conflicts: gcc-5.3.0-r0[so:libcc1.so.0=0.0.0]
satisfies: world[gcc-pass2-i486-alpine-linux-musl]
How could I solve this? Should I build gcc-pass-2 with different prefix than /usr/ to avoid conflict dynamic libs? If I do so, will it be any different than a manually/traditionally built cross-toolchain ? (mentioned below)
Q2:
I have built a cross toolchains targeting s390x (gcc, musl, binutils, busybox, apk-tools), based on Gregor Richards's musl-cross with some patches.
If I specifies this cross toolchains in the crossbuild-alpine-bootstrap.sh , rather than doing
${SUDO_APK} --repository $REPODEST_HOST/main add gcc-$CTARGET g++-$CTARGET gcc-gnat-$CTARGET || return 1
then will there be any differences ? I have not try this (havent have cross-built gnat yet) and just want to know what you think about it.
Thank you,
Tuan
