Hello. This is my first post. Any help is welcome
I am following the tutorial to build gcc for cross compiling:
https://wiki.osdev.org/GCC_Cross-CompilerI am building in a Lubuntu Virtual Box machine.
I installed all the dependencies listed in the tutorial except:
CLooG (Optional)
ISL (Optional)
Lubuntu doesn't find them.
Since they are optional I tried to build gcc.
To this point all is ok:
---------------------------------------------------------
cd $HOME/src
# The $PREFIX/bin dir _must_ be in the PATH. We did that above.
which -- $TARGET-as || echo $TARGET-as is not in the PATH
mkdir build-gcc
cd build-gcc
../gcc-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++ --without-headers
---------------------------(All above OK)----------------------------
When I apply:
make all-gcc
after a lot of time I get the following error:
++ -no-pie -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -Woverloaded-virtual -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -static-libstdc++ -static-libgcc -o lto1 \

make[1]: Leaving directory '/home/arbol/src/build-gcc/gcc'
make: *** [Makefile:4390: all-gcc] Error 2
I am using and old PC and the building took more than an hour to finally crash because of this error.
Thanks for your help.
