I noticed that the biggest reduction in compile-time was due to using precompiled headers - now error messages come out in 3-5 seconds on my initial Windows program (~140 lines of C++). I have an AT&T 6386/SX (16 MHz 386SX) with 2.0 Mb, and use bcx under windows in standard mode. The entire compile/link/resource-compile sequence (ultimately successful) takes ~ 30 sec. My only problem is memory - with 2MB, I cannot reserve 640kb for tkernel, run windows, run bcx, run the resource toolkit, AND run my test program. The big memory hog is the resource toolkit (and windows, of course, and tkernel). Tom Roberts att!ihlpl!tjrob TJROB@IHLPL.ATT.COM
