Compiler error - missing iconv.h with -mno-cygwin
Hi, I have a program that uses libxml2 and compiles fine under Cygwin when I compile it as a Cygwin app. However, I want to compile a stand-alone version so I updated the Makefile to add CFLAGS += -mno-cygwin and LDFLAGS += -mno-cygwin (I'm using gcc 3.4.4), and with these it fails to compile because it cannot find iconv.h: gcc -I/usr/include/libxml2 -mno-cygwin -c -o xmlParse.o xmlParse.c In file included from /usr/include/libxml2/libxml/parser.h:797, from xmlParse.c:36: /usr/include/libxml2/libxml/encoding.h:28:19: iconv.h: No such file or directory In file included from /usr/include/libxml2/libxml/parser.h:797, from xmlParse.c:36: /usr/include/libxml2/libxml/encoding.h:136: error: parse error before iconv_t /usr/include/libxml2/libxml/encoding.h:136: warning: no semicolon at end of struct or union /usr/include/libxml2/libxml/encoding.h:137: warning: data definition has no type or storage class make: *** [xmlParse.o] Error 1 But iconv.h does exist in /usr/include, so why can the compiler not find it? Is it looking somewhere different for include files when compiling with -mno-cygwin?

Is it looking somewhere different for include files when compiling with -mno-cygwin? Yes, the compiler is looking somewhere else when you use -mno-cygwin; after all, that option means that you are not compiling for cygwin (implicitly, it means you are cross-compiling for mingw). The confusion caused by this option that turns on cross-compilation is also the reason that the gcc-4 release will not support -mno-cygwin. Search the list archives for more details. Ask the mingw list if you need more details of why mingw does not provide iconv.h. - -- Don't work too hard, make some time for fun as well!
