Moin,
ich habe gestern meinen Raspberry Pi bekommen. Habe entsprechend Gentoo Wiki dort auch Gentoo installiert bekommen. Da die Rechenpower ja begrenzt ist, kann man ja mittels distcc nachhelfen oder - soweit ich das Embedded Handbuch richtig verstanden habe - auf einem anderen Rechner die Pakete kompilieren und dann übertragen. Zweiteres habe ich versucht. Die Cross-Toolchain (crossdev -S armv6j-hardfloat-linux-gnueabi) ist erfolgreich eingerichtet und etliche weitere Pakete damit kompiliert. Bei dev-libs/mpc kommt dann aber ein Fehler:

Code:

skycaptain arne # emerge-armv6j-hardfloat-linux-gnueabi --oneshot dev-libs/mpc

These are the packages that would be merged, in order:

Calculating dependencies  ... done!
[ebuild  N     ] dev-libs/mpc-0.8.2 to /usr/armv6j-hardfloat-linux-gnueabi/ 0 kB

Would you like to merge these packages? [Yes/No]

Soweit ich es verstehe, versucht er mpfr zu linken, erkennt aber nicht dessen Dateiformat. Das macht Sinn, wenn er das mpfr von meinem amd64 Rechner verwendet anstatt das mpfr vom cross compile.
Aber warum macht er das nicht? Kann ich mittels crossdev also kein System auf einen anderen Rechner kompilieren? Kenne mich in Embedded-Sachen nicht wirklich aus.
