2000.01.31 18:29 "Re: Threadsafe MSVC implementation of LibTiff", by Scott Wagner
The build of libtiff which I use is built from source by me - not Frank Warmerdam's build. Mine is a threadsafe DLL, and I call it from multithreaded applications. My experience is that (at least with my Borland compiler) the default C runtime library code selected is the more compact single-thread version; I have to select the multi-threaded CRTL as an option. This is probably true of VC++ as well. Frank, can you comment on this?
