I have successfully compiled 4.8 for my native system, Ubuntu Linux.
Now I'm trying to build a cross compiler to generate ARM code for the
Beagle Bone. Having a few problems.
Thank you for including the config.log file. The relevant error is:
/usr/bin/as: unrecognized option '-meabi=5'
Before building a cross-compiler, you need to build a cross-assembler.
It looks like you have not done that.
Thanks for your reply, Ian. I have the binaries for the 4.6 ARM
cross-compiler on this machine. There is a arm-linux-gnueabi-as file in
/usr/bin. Can I not use that assembler? If so, how to tell configure?
If that doesn't work could you point me in the right direction for
building the assembler? That's totally uncharted waters for me.
Googling didn't help much.
Thanks
John
You use this configure command for GCC:
./configure --build=arm-angstrom-linux-gnueabi
--host=arm-angstrom-linux-gnueabi --prefix=/usr/arm-linux-gnueabi-4.8
-bindir=/usr/local/bin --disable-fortran --disable-java --disable-lto
--disable-objc -enable-neon
For a cross-compiler you normally specify a --target. So maybe the command
should look like this:
path/to/gcc/source/configure --target=arm-angstrom-linux-gnueabi
--prefix=/opt/arm-linux-gnueabi-4.8 --disable-fortran --disable-java
--disable-lto --disable-objc -enable-neon
Do not build in the source tree.
To build the Binutils you may use this:
path/to/binutils/source/configure --target=arm-angstrom-linux-gnueabi
--disable-werror --prefix=/opt/arm-linux-gnueabi-4.8
Make sure that the new Binutils are in your path before you build GCC.
