Wie erstelle ich den GCC Cross Compiler für Cross Linux From Scratch (CLFS) für Beagleboard?

Derzeit versuche ich, ein eingebettetes Linux von Grund auf mit den Anweisungen von Cross Linux von Grund auf neu zu erstellen .

Alles hat gut funktioniert, bis ich versucht habe, den GCC Cross-Compiler zu kompilieren. Ich möchte das Linux für das Beagleboard-xM erstellen ... Also habe ich die folgenden Einstellungen gewählt:

export CLFS_ABI="aapcs-linux"
export CLFS_HOST="x86_64-cross-linux-gnu"
export CLFS_TARGET="armv7a-unknown-linux-uclibceabi"
export CLFS_ARCH="arm"
export CLFS_ENDIAN="little"
export CLFS_ARM_ARCH="armv7"
export CLFS_ARM_MODE="arm"
export CLFS_FLOAT="hard"
export CLFS_FPU="neon"

Nein, sobald ich versuche, die Anweisungen auf dieser Seite auszuführen, tritt beim Befehl make all-gcc all-target-libgccein Fehler auf.

Was vermisse ich?

Die Fehler sind wahrscheinlich auf eine falsche Kombination von Build-Variablen zurückzuführen.

Auf der Seite CLFS Build Variable finden Sie detaillierte Erläuterungen zu den besten Kombinationen von Variableneinstellungen für verschiedene Architekturen.

Ähnliche Probleme beim Konfigurieren von Skripten wurden durch Ändern der CLFS_ARCHVariablen in behobenthumb

Bei einem anderen ähnlichen Fehler beim Konfigurieren von BeagleBoard-Skripten scheinen die folgenden Variablen den Trick zu tun:ARMv7-A Thumb-2 - Little-Endian, Soft-Float, GLIBC

Wenn Sie CLFS 1.xx verwendet haben, sollten Sie CLFS 2.xx für einen saubereren Build-Ansatz mit aktualisierter Dokumentation verwenden .

Der beste Ort, um CLFS-Probleme zu diskutieren, ist die Mailingliste für den clfs-Support. Stellen Sie dort Ihre Frage, um weitere Informationen zu erhalten .
