将 libssl 与 nmake 一起使用

Question

    LIBS =   ws2_32.lib winmm.lib advapi32.lib  crypt32.lib user32.lib gdi32.lib   libeay32.lib ssleay32.lib 

OSCOMPAT = /DWIN32 /D_WIN32_WINNT=0x0400
VSCOMPAT = /D_CRT_SECURE_NO_DEPRECATE /D_CRT_NONSTDC_NO_DEPRECATE  
CFLAGS= -I . -I$C /MT /W3 $(OSCOMPAT) $(VSCOMPAT) -nologo $(EXTRACFLAGS)

test: $(CCLIENTLIB) test.obj oauth.obj hash.obj oauth_http.obj xmalloc.obj 
    LINK /NOLOGO mtest.obj oauth.obj hash.obj oauth_http.obj xmalloc.obj  $(LIBS) 


test.obj:test.c 
oauth.obj: oauth.c
hash.obj: hash.c
oauth_http.obj: oauth.h oauth_http.c
xmalloc.obj: xmalloc.c

我收到以下错误

make file 中的问题是什么。 如何将 libssl 与我的应用程序链接？

您可以从此处下载代码 https://rapidshare.com/files/458792519/test.rar （它包括来自 liboauth 的代码）

Answer 1

为了总结 OP 评论中的对话，我下载了示例代码并对其运行了 nmake (makefile.nt)。我确实遇到了链接器错误，但缺少的符号来自 Win32 库。我将 user32.lib 和 gdi32.lib 添加到 makefile 中的 LIBS 列表中，然后干净地链接（该构建适用于 VS2005、VS2008 和 VS2010）。

正如OP指出的那样，在添加这两个额外的库时它也干净地链接起来。我不清楚这将如何帮助解析 libeay32.lib 中的这些符号。所以我怀疑对 make 文件的更改导致了所有 .obj 文件的完全重建和编译。完全干净的构建使其正常工作。所以也许（我只是猜测）.obj 文件最初编译不正确（编译器可能与链接器不能很好地工作？）并且完全重建使一切保持一致。
