On my computer , neither FPC nor Lazarus are installed . There is an option to specify either dynamic linking or static linking of libraries . When static linking is selected , it is necessary to have static linkable libraries ( *.a ) of used parts , i.e. , dynamic linkable libraries ( *.so.* ) can not be used for static linking . https://www.google.com/search?q=lazarus+static+linking+of+libraries&sxsrf=AJOqlzXTPuAEwc2JkAaon6mLwAvBM-kn5A%3A1679053415469&ei=Z1IUZL2NHP-Qxc8PqvqOuAM&ved=0ahUKEwj93Iyz8eL9AhV_SPEDHSq9AzcQ4dUDCA4&uact=5&oq=lazarus+static+linking+of+libraries&gs_lcp=Cgxnd3Mtd2l6LXNlcnAQAzIFCCEQoAE6BwgAEB4QsAM6BAgjECc6BggAEBYQHjoICAAQFhAeEAo6CAgAEBYQHhAPOgUIABCRAjoFCAAQgAQ6BwguEIAEEAo6BwgAEIAEEAo6CgguEIAEENQCEAo6CAgAEIAEEMsBOgsILhCABBDUAhDLAToICC4QgAQQywE6BQguEIAEOgsILhCABBDHARCvAToKCAAQgAQQFBCHAjoHCAAQDRCABDoICAAQBRAeEA06BAghEBU6BwghEKABEApKBAhBGAFQpBdYi8IBYIHJAWgDcAB4AIABxwGIAcYikgEEMC4zNpgBAKABAcgBAsABAQ&sclient=gws-wiz-serp lazarus static linking of libraries Comparison of Linux and Windows is not a fruitful action , because they do not have much similarity other than being operating systems .
