Missing "release/RDRAND_Tester_Linux" file/directory about rdrand-tester HOT 4 CLOSED

Please manually create a release directory if it does not exist before executing the gcc command. Alternatively, change the -o parameter from release to a directory that exists.

Try:
gcc RDRAND_Tester.c -o ../RDRAND_Tester_Linux -Wall -Wconversion -Wformat-security -O3 -s
The other options are good security practice but not essential to the functionality of this simple application.

Anyway, the errors seem to be a compiler related and not concerning the code of this application. I cannot help further as I am not familiar with Fedora and not an expert with GCC.

I noted that touch ../<file> was not needed prior to the execution of this gcc command. This command you just suggested and the gcc one that here follows are executed without extra messages. Time to test the binary file created by this process; ./RDRAND_Tester_Linux. It is operational.

$ find .. -maxdepth 1 -type f -ls
$ gcc RDRAND_Tester.c -o ../RDRAND_Tester_Linux -Wall -Wconversion -Wformat-security -O3 -fstack-protector-strong -D_FORTIFY_SOURCE=2 -fPIE -fstack-clash-protection -fcf-protection -s
$ find .. -maxdepth 1 -type f -ls
