Hello,
I'm trying to build a crossed native gcc 4.9.1 for arm (linux) on a x86
host. Thus, I have tried to configure gcc tree with :
../gcc-4.9.1/configure --target=arm-cortexa9_neon-linux-gnueabihf
--enable-languages=c,c++,fortran --enable-bootstrap
--with-gmp=/home/bertrand/cross --prefix=/home/bertrand/q7
--with-build-sysroot=/home/bertrand/x-tools/arm-cortexa9_neon-linux-gnueabihf/arm-cortexa9_neon-linux-gnueabihf/sysroot
--disable-threads --build=x86_64-unknown-linux-gnu
--host=arm-cortexa9_neon-linux-gnueabihf
Build aborts in stage 2 with :
checking for arm-cortexa9_neon-linux-gnueabihf-gcc...
/home/bertrand/cross/build/./prev-gcc/xgcc
-B/home/bertrand/cross/build/./prev-gcc/
-B/home/bertrand/q7/arm-cortexa9_neon-linux-gnueabihf/bin/
--sysroot=/home/bertrand/x-tools/arm-cortexa9_neon-linux-gnueabihf/arm-cortexa9_neon-linux-gnueabihf/sysroot
checking for C compiler default output file name...

I have checked xgcc format and xgcc is built for arm, not for x86 :
schroedinger:[~/cross/build/intl] > file
/home/bertrand/cross/build/./prev-gcc/xgcc
/home/bertrand/cross/build/./prev-gcc/xgcc: ELF 32-bit LSB executable,
ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), for
GNU/Linux 2.6.16, not stripped
On https://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html, I can read :
"If host and target are the same, but build is different, you are using
a cross-compiler to build a native for a different system."
I suppose I have done a mistake... Any idea to build a crossed native
compiler ?
Best regards,
JKB
