xpdf编译的第四个错误

原本以为解决了freetype2.lib的问题后就会成功了，结果：

LINK : warning LNK4098: 预设的程式库 ‘MSVCRT’ 与其他使用的程式库冲突，请使用 /NODEFAULTLIB:library
pdftoppm.exe : fatal error LNK1169: 找到有一或多个已定义的符号

后来Google到Linker Tools Warning LNK4098
defaultlib “library” conflicts with use of other libs; use /NODEFAULTLIB:library

这一篇的这个表格：

The table below shows which libraries should be ignored depending on which run-time library you want to use.
To use this run-time library
Ignore these libraries
Single-threaded (libc.lib)
libcmt.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib
Multithreaded (libcmt.lib)
libc.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib
Multithreaded using DLL (msvcrt.lib)
libc.lib, libcmt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib
Debug Single-threaded (libcd.lib)

原创 关于LNK4098MSDN中的一些说明收藏

Linker Tools Warning LNK4098
defaultlib “library” conflicts with use of other libs; use /NODEFAULTLIB:library
You are trying to link with incompatible libraries.
Important The run-time libraries now contain directives to prevent mixing different types. You’ll receive this warning if you try to use different types or debug and non-debug versions of the run-time library in the same program. For example, if you compiled one file to use one kind of run-time library and another file to use another kind (for example, single-threaded versus multithreaded) and tried to link them, you’ll get this warning. You should compile all source files to use the same run-time library. See the Use Run-Time Library (MD, /ML, /MT, /LD) compiler options for more information.
You can use the linker’s /VERBOSE:LIB switch to determine which libraries the linker is searching. If you receive LNK4098 and want to create an executable file that uses, for example, the single-threaded, non-debug run-time libraries, use the /VERBOSE:LIB option to find out which libraries the linker is searching. The linker should print LIBC.LIB and not LIBCMT.LIB, MSVCRT.LIB, LIBCD.LIB, LIBCMTD.LIB, or MSVCRTD.LIB as the libraries searched. You can tell the linker to ignore the the incorrect run-time libraries by typing the incorrect libraries in the Ignore Libraries text box on the Link tab of the Settings dialog box in Developer’s Studio or by using the /NODEFAULTLIB:library option with LINK for each library you want to ignore. See the Ignore Libraries (/NODEFAULTLIB) linker option for more information.
The table below shows which libraries should be ignored depending on which run-time library you want to use.
To use this run-time library
Ignore these libraries
Single-threaded (libc.lib)
libcmt.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib

引起我的注意，我猜我在建置时可能选错了方案组态，所以我将Release改成Release Multithreaded重新建置后，再重新编译xpdf可真的成功了！！没有错误接下来就试试看能不能使用了！
