Hello all, I tried to install crosstoolchain packages for arm and powerpc architectures on GNU/Linux 7.7 (wheezy) distro with kenel debian 3.2.0.4-686-pae #1 SMP Debian 3.2.63-2+deb7u2 i686 GNU/Linux. Here is a list of command sequence I used, this manual I took from here. debootstrap sid sid chroot sid Added "deb http://emdebian.org/tools/debian/ jessie main" in "/etc/apt/sources.list" curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key |apt-key add - dpkg --add-architecture powerpc dpkg --add-architecture armel sudo apt-get update Everything goes fine untill the moment I want to install crossbuild-essential-armhf package, the command apt-get install crossbuild-essential-armhf gives me The following packages have unmet dependencies: crossbuild-essential-armhf : Depends: gcc-arm-linux-gnueabihf (>= 4.9.1-1) but it is not going to be installed Depends: g++-arm-linux-gnueabihf (>= 4.9.1-1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. Attempts to install crossbuild-essential-powerpc with this command apt-get install crossbuild-essential-powerpc gives me The following packages have unmet dependencies: crossbuild-essential-powerpc : Depends: gcc-powerpc-linux-gnu (>= 4.9.1-1) but it is not going to be installed Depends: g++-powerpc-linux-gnu (>= 4.9.1-1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. All attempts to intall missing dependencies for powerpc architecture leaded to: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package gcc-powerpc-linux-gnueabihf For arm croosstoolchain, it ends up with The following packages have unmet dependencies: g++-arm-linux-gnueabihf : Depends: g++-4.9-arm-linux-gnueabihf (>= 4.9.2-2) but it is not going to be installed E: Unable to correct problems, you have held broken packages. What did I do wrong? How could I satisfy missing dependencies?? Thank you in advance. Kind Regards, Oleg |
