To set this definition + you have the following alternatives: + + - Modify lib/config-win32.h and src/config-win32.h + - Modify lib/Makefile.vc6 + - Add definition to Project/Settings/C/C++/General/Preprocessor Definitions + in the vc6libcurl.dsw/vc6libcurl.dsp Visual C++ 6 IDE project. + + Once that libcurl has been built with BSD-style lwIP TCP/IP stack support, + in order to use it with your program it is mandatory that your program + includes lwIP header file <lwip/opt.h> (or another lwIP header that includes + this) before including any libcurl header. Your program does not need the + USE_LWIPSOCK preprocessor definition which is for libcurl internals only. + + Compilation has been verified with lwIP 1.4.0 and contrib-1.4.0 from: + + http://download.savannah.gnu.org/releases/lwip/lwip-1.4.0.zip + http://download.savannah.gnu.org/releases/lwip/contrib-1.4.0.zip + + This BSD-style lwIP TCP/IP stack support must be considered experimental + given that it has been verified that lwIP 1.4.0 still needs some polish, + and libcurl might yet need some additional adjustment, caveat emptor. + Important static libcurl usage note ----------------------------------- |
