Hi,

I am very new to OpenFOAM and Linux and am trying to install OpenFOAM onto a raspberry pi 4 using this guide

http://www.wolfdynamics.com/images/r...nFOAM-RPI3.pdf

Everything seems to be working however when I reach the last step of compiling the following error is returned


Allwmake /root/OpenFOAM/OpenFOAM-dev
gcc -DlinuxARM7 -DWM_ARCH_OPTION=32 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -O3 -floop-optimize -falign-loops -falign-labels -falign-functions -falign-jumps -fprefetch-loop-arrays -mcpu=cortex-a9 -mfpu=vfpv3-d16 -mfloat-abi=softfp -fPIC dirToString.c -o /root/OpenFOAM/OpenFOAM-dev/wmake/platforms/linuxARM7Gcc/dirToString
In file included from /usr/include/features.h:448,

from dirToString.c:43:
/usr/include/arm-linux-gnueabihf/gnu/stubs.h:7:11: fatal error: gnu/stubs-soft.h: No such file or directory
# include <gnu/stubs-soft.h>
^~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:68: /root/OpenFOAM/OpenFOAM-dev/wmake/platforms/linuxARM7Gcc/dirToString] Error 1
root@raspberrypi:~/OpenFOAM/OpenFOAM-dev#


If anyone has any advice on this it would be greatly appreciated

In directory wmake/rules/linuxARM7Gcc, for two files, cOpt and c++Opt, option '-mfloat-abi=softfp', change 'softfp' to 'hard'.

ARM7 in RPI4 has a hardware floating point processor. The developers probably didn't see any need to support soft-float calling conventions.

See https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html:
-mfloat-abi=name
Specifies which floating-point ABI to use. Permissible values are: ‘soft’, ‘softfp’ and ‘hard’.

Specifying ‘soft’ causes GCC to generate output containing library calls for floating-point operations. ‘softfp’ allows the generation of code using hardware floating-point instructions, but still uses the soft-float calling conventions. ‘hard’ allows generation of floating-point instructions and uses FPU-specific calling conventions.

The default depends on the specific target configuration. Note that the hard-float and soft-float ABIs are not link-compatible; you must compile your entire program with the same ABI, and link with a compatible set of libraries.
