Good evening,
I am trying to cross compile gcc 14 (c, c++) in an Intel platform for
armhf and arm64. I am trying with multiple option sets without success.
Can somebody help me with this, please?
It helps if you tell us what you tried, what that returns in, and what
you expected or wanted instead?
I tried to cross compile in Debian Bookworm in Intel.
I installed
binutils-arm-linux-gnueabi \
linux-libc-dev-armhf-cross \
crossbuild-essential-armhf \
build-essential \
gcc-arm-linux-gnueabihf \
g++-arm-linux-gnueabihf \
libc6-dev-armhf-cross \
dpkg-dev \
debhelper \
fakeroot \
devscripts \
dh-make \
flex \
bison \
libgmp-dev \
libmpfr-dev \
libmpc-dev \
libgmp-dev:armhf \
libmpfr-dev:armhf \
libmpc-dev:armhf \
libunwind-dev:armhf \
zlib1g-dev \
wget
The command I run was:
SOURCE_DIR=~/gcc-host/source
BUILD_DIR="~/gcc-host/build/armhf"
INSTALL_DIR="~/gcc-host/install/armhf"
GCC_VERSION=14.2.0
MACHTYPE=x86_64-linux-gnu
cd "$BUILD_DIR"
$SOURCE_DIR/gcc-$GCC_VERSION/configure --prefix="$INSTALL_DIR"
--build=$MACHTYPE --host=arm-linux-gnueabihf
--target=arm-linux-gnueabihf --enable-languages=c,c++ --enable-multilib
--with-sysroot=/usr/arm-linux-gnueabihf
--with-native-system-header-dir=/include
make V=1 -j$(nproc)
Make command stops:

I hope it can be helpful
And something that makes us believe you actually read the installation
instructions, and tried to follow them, of course ;-)
