I'm trying to build a native Windoze console application using gcc under the Cygwin environment. I am using the following make options: CXXFLAGS += -mno-cygwin CPPFLAGS += -I/usr/include/g++-3 LDFLAGS += -v -mno-cygwin LOADLIBES += -lstdc++ -lwsock32 This gives me the following command lines and error messages when I compile: Building MINGWdebug version of /cygdrive/d/software/stlplus/test/TCP/client make -C ../../../../stlplus/source Building MINGWdebug version of /cygdrive/d/software/stlplus/source make[1]: Entering directory `/cygdrive/d/software/stlplus/source' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/cygdrive/d/software/stlplus/source' gcc -v -mno-cygwin MINGWdebug/libTCP.a ../../../../stlplus/source/MINGWdebug/libstlplus.a -lstdc++ -lwsock32 -o client Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/specs gcc version 2.95.3-5 (cygwin special) /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/collect2.exe -Bdynamic --dll-search-prefix=cyg -o client.exe /usr/lib/mingw/crt2.o -L/usr/lib/mingw -L/usr/lib/w32api -L/usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5 MINGWdebug/libTCP.a ../../../../stlplus/source/MINGWdebug/libstlplus.a -lstdc++ -lwsock32 -lmingw32 -lgcc -lmoldname -lmsvcrt -lmingw32 -luser32 -lkernel32 -ladvapi32 -lshell32 -lmingw32 -lgcc -lmoldname -lmsvcrt /usr/lib/libstdc++.a(iostream.o)(.text+0x148):iostream.cc: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iostream.o)(.text+0x515):iostream.cc: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iostream.o)(.text+0x17b3):iostream.cc: undefined reference to `_impure_ptr' /usr/lib/libstdc++.a(iostream.o)(.text+0x17c4):iostream.cc: undefined reference to `_impure_ptr' /usr/lib/libstdc++.a(stdstrbufs.o)(.text+0x4e):stdstrbufs.cc: undefined reference to `_impure_ptr' /usr/lib/libstdc++.a(streambuf.o)(.text+0x3e3):streambuf.cc: undefined reference to `__errno' /usr/lib/libstdc++.a(fileops.o)(.text+0x19d):fileops.c: undefined reference to `__errno' /usr/lib/libstdc++.a(fileops.o)(.text+0x210):fileops.c: undefined reference to `__errno' /usr/lib/libstdc++.a(fileops.o)(.text+0x26d):fileops.c: undefined reference to `__errno' /usr/lib/libstdc++.a(fileops.o)(.text+0x398):fileops.c: undefined reference to `__errno' /usr/lib/libstdc++.a(fileops.o)(.text+0x45d):fileops.c: more undefined references to `__errno' follow /usr/lib/libstdc++.a(floatconv.o)(.text+0x1287):floatconv.c: undefined reference to `_imp____infinity' /usr/lib/libstdc++.a(floatconv.o)(.text+0x13e5):floatconv.c: undefined reference to `__errno' /usr/lib/libstdc++.a(iovfscanf.o)(.text+0x61):iovfscanf.c: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iovfscanf.o)(.text+0x8d):iovfscanf.c: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iovfscanf.o)(.text+0x55c):iovfscanf.c: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iovfscanf.o)(.text+0x5ac):iovfscanf.c: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iovfscanf.o)(.text+0x823):iovfscanf.c: undefined reference to `_imp___ctype_' /usr/lib/libstdc++.a(iovfscanf.o)(.text+0x87d):iovfscanf.c: more undefined references to `_imp___ctype_' follow collect2: ld returned 1 exit status make: *** [client] Error 1 I have found definitions for __errno in libmsvcrt.a (so why is that failing?) but I cannot find any definitions of _imp___ctype_ in any of the libraries in /lib/mingw. Some version numbers in case they help: cygwin-1.3.3-2.tar.bz2 gcc-2.95.3-5.tar.bz2 mingw-runtime-1.1-1.tar.bz2 Can anyone suggest what I'm doing wrong here?
