Hi! I have looked around in the documentation and FAQs about my question, but I don't seem to have found a satisfying answer. My problem is that the boost libraries (especially function) seem to successfully boost the code size of my C++ Builder program, too. The source written by me is around twenty-some thousands of lines, plus the VCL and stdc++ headres, the end result may be somewhere around half a million lines in summary. But after having added some boost headers (mainly function and bind) to where it's appropriate, the amount of compiled lines on a full rebuild jumped to the ten million (!) range. This is way too much. I'm not using any so that much advanced stuff that it would be justified - and the compilation time is inacceptable for such a small app. So, does anyone have some clues regarding why boost may cause so much bloat, and how I could reduce that? thx mortee
