Hello everyone, I have used -shared options for a long time. Today when I dig into the detailed description of shared option of gcc, I found something strange to me. Quote from gcc man page, -------------------- -shared Produce a shared object which can then be linked with other objects to form an executable. Not all systems support this option. For predictable results, you must also specify the same set of options that were used to generate code (-fpic, -fPIC, or model suboptions) when you specify this option.[1] 1. On some systems, gcc -shared needs to build supplementary stub code for constructors to work. On multi-libbed systems, gcc -shared must select the correct support libraries to link against. Failing to supply the correct flags may lead to subtle defects. Supplying them in cases where they are not necessary is innocuous. -------------------- I only understand this statement "Produce a shared object which can then be linked with other objects to form an executable." and I do not know what are the other points mean. Could anyone help to introduce what do they mean and will the points impact my current work/previous comprehension of shared option of gcc? regards, George __________________________________________________ Do You Yahoo!?
