corrupt dwg file generated from xcode
corrupt dwg file generated from xcode
hi,
we're using dd libs 1.14.02. our app has only recently migrated to xcode. we now use the dd libs built with vc8, codewarrior 9 and xcode 2.2.
the dwg files produced using xcode are corrupt. it can't be read back in our app or in autocad.
dxf files generated with xcode are perfectly fine.
we tried diff'ing the xcode generated dwg files with the codewarrior ones, but could not make much headway as the format is binary.
the macintosh platform is currently ppc (not mactel).
both dwg and dxf export is working fine with codewarrior.
i've attached a zip file containing files (both dwg and dxf) generated with codewarrior and xcode.
please help.

by default xcode uses the -os optimization setting, and this setting was causing incorrect data to be written out to the dwg files. rebuilding the libs without optimizations fixes the problem. a no-optimization version of the xcode and ub libs have been posted on our member download pages, in place of the original downloads.

dwg export is working fine with the new ub libs. thanks for resolving this early.
just an observation, the size of the libs after removing the optimization is huge (the 11 libs we were linking with earlier amounted to 64+ mb and now take up 103+ mb).
i've heard that with xcode 2.3, apple has done much to reduce the size of the ub. the only downside is that libs built with 2.3 will not work for 2.2 projects.
will you be providing 2.3 built libs in your next release?
thanks,
varun
xcode 2.3 doesn't seem to be available yet, but we will upgrade as soon as it is released.
