x86 platforms may compile dosbox to use the dynamic-x86 (faster core) or the dynrec core. However, in compiling dosbox-SVN+3dfx_patch with the dynrec core there are a couple of errors which also occur in compiling the 64-bit linux version (credit to Ykhwong). That web link has information to bypass the errors as shown below.
