QorIQ SDK2.0 compile float

shunpinglin — Wed, 11 Oct 2017 09:29:19 GMT

Now, I use the SDK2.0 to compile my program which had float variable, but gcc display:

MPFR: Can't allocate memory (size=4294967288)
hello.c: In function 'main':
hello.c:5:5: internal compiler error: Aborted
float a=1.0;

The program:

#include <stdio.h>

int main()
{
float a=1.0;
a += 2;
printf("a:%f \n",a);
return 0;
}

compile the program with the flowing command:

arm-fsl-linux-gnueabi-gcc -march=armv7-a -mfloat-abi=hard -mfpu=neon -mtune=cortex-a7 --sysroot=/opt/fsl-qoriq/2.0/sysroots/cortexa7hf-vfp-neon-fsl-linux-gnueabi hello.c -o hello
MPFR: Can't allocate memory (size=4294967288)
hello.c: In function 'main':
hello.c:5:5: internal compiler error: Aborted
float a=1.0;
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

It seems that gcc MPFR's bug, then I how to fix it?

It looks like that toolchain on your Linux host PC is not correctly installed.

Use the following command sequence for toolchain installing and GCC using.

We use ls012atwr as example.

bitbake fsl-toolchain

Run ./fsl-qoriq-glibc-x86_64-cortexa7hf-vfp-neon-toolchain-2.0.sh

from the following folder:

/QorIQ-SDK-V2.0-20160527-yocto/build_ls1021atwr/tmp/deploy/sdk$

source ./environment-setup-cortexa7hf-vfp-neon-fsl-linux-gnueabi

$CC test_float.c -o test_float.elf

Have a great day,

There are no problems if this toolchain is used for float operations.

Have a great day,

What error messages do you see?

Perhaps there is a problem for permission for toolshain installing.

Have a great day,

Pavel,I have this issue,too.

I compile simple code with arm-fsl-linux-gnueabi-gcc ,it works.

But I compile libmodbus and iproute2 with arm-fsl-linux-gnueabi-gcc,It will print MPFR: Can't allocate memory (size=4294967288).

Is something wrong here?
