Re: Building libcurl 7.57 on Windows
Thanks for the information Ray, I finally got the library built on Windows using the MakefileBuild.vc. But I have to path MakefileBuild.vc so that I can download the source tar ball, apply the patch, and proceed with the build without manual tweaking. It would be nice if libcurl can take the following changes in MakefileBuild.vc for future releases. 1. !IF "$(VC)"=="6" CC_NODEBUG = $(CC) /O2 /DNDEBUG CC_DEBUG= $(CC) /Od /Gm /Zi /D_DEBUG /GZ CFLAGS = /I. /I../lib /I../include /nologo /W4 /wd4127 /GX /DWIN32 /YX /FD /c /DBUILDING_LIBCURL $(CFLAGSZLIB) ß Add CFLAGSZLIB macro to CFLAGS so I can define ’CFLAGSZLIB=/DZLIB_WINAPI’ in command line parameters to ’nmake’ !ELSE CC_NODEBUG = $(CC) /O2 /DNDEBUG CC_DEBUG= $(CC) /Od /D_DEBUG /RTC1 /Z7 /LDd CFLAGS = /I. /I ../lib /I../include /nologo /W4 /wd4127 /EHsc /DWIN32 /FD /c /DBUILDING_LIBCURL $(CFLAGSZLIB) !ENDIF 2. !IF "$(WITH_ZLIB)"=="dll" !IFNDEF ZLIB_LIBS ß--- This check allows users to override ZLIB_LIBS with their definition of zlibwapi.lib. ZLIB_LIBS = zlib.lib !ENDIF USE_ZLIB= true ZLIB= dll !ELSEIF "$(WITH_ZLIB)"=="static" ZLIB_LIBS = zlib_a.lib USE_ZLIB= true ZLIB= static !ENDIF Thanks for the help.

Re: Building libcurl 7.57 on Windows
Those unresolved symbol errors come from content_encoding.c. They are referenced in older versions, e.g. 7.51.0, where they linked with the same zlibwapi without problems.
