openssl 3.0.5 failing on rasperrypi 22.04

I have tried following build from source steps

curl -OJ https://www.openssl.org/source/openssl-3.0.5.tar.gz
tar -xzf openssl-3.0.5.tar.gz
cd openssl-3.0.5
./config shared -Wl,-rpath=/opt/openssl/lib64 --prefix=/opt/openssl --openssldir=/opt/openssl/ssl
make -j 4
make install
cd ..
rm /usr/bin/openssl
ln -s /opt/openssl/bin/openssl /usr/bin/openssl
ln -s /etc/ssl/certs/*.* /opt/openssl/ssl/certs/
echo "/opt/openssl/lib64" > /etc/ld.so.conf.d/openssl.conf
ldconfig
reboot

However during the make process I get the following error:

'-mfloat-abi=hard': selected processor lacks an FPU

I however believe that the rpi4 does in fact have one. Am I mistaken or is there some other error? Help would be appreciated

Solution

So what you can do to solve this is include the instruction set to which you are compiling openSSL

#!/bin/bash
set -e

if [[ $1 != '' ]]
then
    echo "Getting openssl version ${1}"
    sudo apt -y install libcurl4-openssl-dev librtmp-dev curl
    curl -OJ "https://www.openssl.org/source/openssl-${1}.tar.gz"
    tar -xzf openssl-${1}.tar.gz
    cd openssl-${1}
    ./config shared -Wl,-rpath=/opt/openssl/lib --prefix=/opt/openssl --openssldir=/opt/openssl/ssl -march=armv7-a+fp
    make -j 4
    make install
    cd ..
    rm /usr/bin/openssl
    ln -s /opt/openssl/bin/openssl /usr/bin/openssl
    ln -s /etc/ssl/certs/*.* /opt/openssl/ssl/certs/
    echo "/opt/openssl/lib" > /etc/ld.so.conf.d/openssl.conf
    echo "export LD_LIBRARY_PATH=/opt/openssl/lib" > /etc/profile.d/openssl.sh
    ldconfig
    rm openssl-${1}.tar.gz
    rm -rf openssl-${1}
    reboot
else
    echo Please provide latest openssl version \(3.x.x\) from:
    echo https://www.openssl.org/source/
fi

The above script when saved to a bash file. Eg. openssl.sh

Will take care of your problem. Remember to feed in the openssl version you are targeting.

./openssl.sh 3.0.7

-march=armv7-a+fp is only meant for hardware that supports 32 bit arm based instructions such as RaspberryPi's.

Hope this helps!
