使用 arm-fsl-linux-gnueabi-gcc 编译：int64_t 为 32 位长

Question

I'm cross compiling for imx28 cpu with arm-fsl-linux-gnueabi:

[vladimir@vladimir src]$ arm-fsl-linux-gnueabi-g++ -v
Using built-in specs.
Target: arm-fsl-linux-gnueabi
Configured with: /work/arm-toolchains/tmp/src/gcc-4.4.4/configure --build=i686-build_pc-linux-gnu --host=i686-build_pc-linux-gnu --target=arm-fsl-linux-gnueabi --prefix=/work/arm_fsl_gcc_4.4.4_multilib --with-sysroot=/work/arm_fsl_gcc_4.4.4_multilib/arm-fsl-linux-gnueabi/multi-libs --enable-languages=c,c++ --with-pkgversion=4.4.4_09.06.2010 --enable-__cxa_atexit --disable-libmudflap --with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm' --with-gmp=/work/arm-toolchains/tmp/arm-fsl-linux-gnueabi/build/static --with-mpfr=/work/arm-toolchains/tmp/arm-fsl-linux-gnueabi/build/static --with-ppl=/work/arm-toolchains/tmp/arm-fsl-linux-gnueabi/build/static --with-cloog=/work/arm-toolchains/tmp/arm-fsl-linux-gnueabi/build/static --enable-threads=posix --enable-target-optspace --with-local-prefix=/work/arm_fsl_gcc_4.4.4_multilib/arm-fsl-linux-gnueabi/multi-libs --disable-nls --enable-symvers=gnu --enable-c99 --enable-long-long --enable-multilib --with-system-zlib --enable-lto
Thread model: posix
gcc version 4.4.4 (4.4.4_09.06.2010) 

The following code line:

info->mask = 0xffffffffffffffff;

gives me following error:

warning: integer constant is too large for 'long' type

I tried close to everything, made sure int64_t is defined to long long int, even tried to typedef it manually, still, it gives me the error.

I also tried different -mcpu options.

Is there even a way to use int64_t on imx28, or should I just give up?

Based on your comment.

Try 0xFFFFFFFFFFFFFFFFLL or -1
