Hello, I have succesfully built the regex library under msvc6sp5, using the vc6-sltport.mak file. But I notice that the compiler gives me warnings relating to the microsoft stl include directories: example: vc98\include\iterator: blah blah blah Should it not be linking to the stlport include files? I have added the stlport directory location into the mak file, and I have it added to the list of include directories via the compiler gui. Thanks. Aaron Boxer boxerab@NOSPAMyahoo.com
