Fix Version: 8.0.0.15
Severity: Standard
Applicable for: Wind River Linux 8
Component/s: Toolchain
Our customer encountered a problem that when they built a LS1043 project (i.e. aarch64) and exported the SDK, gcc included the SDK cannot compile 64-bit application.
The error message says there is not gnu/stubs-soft.h in the sysroot. It seems that __ARM_PCS_VFP macro is not defined when compiling 64-bit application.
I think this issue relate to following link:
- bootstrap build fails on ARM hard float system
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62099
I checked my gcc's configure options, the -with-float=hard option is not specified.
% aarch64-wrs-linux-gcc -v
Using built-in specs.

1. configure a project with following options:
$WIND_BASE/wrlinux/configure --enable-reconfig --enable-board=fsl-ls1043 --enable-kernel=standard --enable-rootfs=glibc-std+debug --enable-build=production --with-rcpl-version=0009
2. make
3. make export-sdk
4. Install the SDK
e.x. /opt/windriver/wrlinux/8.0-fsl-ls1043
5. source the environment file of SDK
. /opt/windriver/wrlinux/8.0-fsl-ls1043/environment-setup-aarch64-wrs-linux
6. Compile hello.c
#include <stdio.h>
int main(void)
{
printf("Hello World!\n");
return 0;
}
7. Following error will be occurred
