Hello, yesterday I spent some time trying to compile the latest VMware demo I just downloaded from the site. After some research I came to the conclusion that it does not work with the Fedora 3 kernel. During the linking stage of vmmon.o two symbols are missing __copy_from_user_ll and __copy_to_user. As I am not too familiar with the kbuild system I don't know exactly where they come from, as they don't show up in the vmmmon-src. linux/hostif.c is just using the plain functions copy_from_user() and copy_to_user(). (I changed both functions to their direct_.. counterparts, getting the same linker errors) After downloading, extracting and preparing the fedora-kernel srpm I found that (one of) the 4G/4G patches is removing the EXPORT_SYMBOL(copy_from_user). Is this the cause for the errors? Is there a way to make vmmon.o link without errors? thanks for your help Oliver
