It doesn't show up in the official list archives: http://gcc.gnu.org/ml/gcc-help/2013-11/msg00061.html Nabble.com is not the home of this list, and apparently doesn't accurately forward what you posted. For the benefit of this list: -------------- Build: msw86d_cpp_gcc in zxStuff (compiler: GNU GCC Compiler)--------------- mingw32-gcc.exe -ansi -D_DLL -D_UNICODE -DUNICODE -shared -D_WIN32 -DZXBUILD_DLL -D_WINDLL -Iinclude -I -c C:\Me\Prjs\cpp\zxStuff\svn\trunk\src\zx\endian\zxcopy.c -o .objs\src\zx\endian\zxcopy.o mingw32-gcc.exe -ansi -D_DLL -D_UNICODE -DUNICODE -shared -D_WIN32 -DZXBUILD_DLL -D_WINDLL -Iinclude -I -c C:\Me\Prjs\cpp\zxStuff\svn\trunk\src\zx\endian\zxcopybits.c -o .objs\src\zx\endian\zxcopybits.o mingw32-gcc.exe -ansi -D_DLL -D_UNICODE -DUNICODE -shared -D_WIN32 -DZXBUILD_DLL -D_WINDLL -Iinclude -I -c C:\Me\Prjs\cpp\zxStuff\svn\trunk\src\zx\endian\zxIntEndian.c -o .objs\src\zx\endian\zxIntEndian.o mingw32-gcc.exe -ansi -D_DLL -D_UNICODE -DUNICODE -shared -D_WIN32 -DZXBUILD_DLL -D_WINDLL -Iinclude -I -c C:\Me\Prjs\cpp\zxStuff\svn\trunk\src\zx\event\zxEVENT.c -o .objs\src\zx\event\zxEVENT.o C:\Users\Lee\AppData\Local\Temp\cczuTp1t.o:zxEVENT.c:(.data+0xfc): undefined reference to `zxVECTOR_resize' C:\Users\Lee\AppData\Local\Temp\cczuTp1t.o:zxEVENT.c:(.data+0x100): undefined reference to `zxVECTOR_opAdd' c:/apps86/tools/codeblocks12-11/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: C:\Users\Lee\AppData\Local\Temp\cczuTp1t.o: bad reloc address 0x100 in section `.data' collect2.exe: error: ld returned 1 exit status Process terminated with status 1 (0 minutes, 3 seconds) 2 errors, 0 warnings (0 minutes, 3 seconds) As I thought, the errors shown are linker errors, not compiler errors. You are using -shared to compile single object files, that is wrong. You probably want to use -fPIC to compile each file, then use -shared to combine them into a single .dll file. So your codeblocks settings must be wrong, but that is not a GCC problem so this is the wrong mailing list.
