使用libssl与nmake

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

我收到了以下错误

制作文件中的问题是什么？如何将libssl链接到我的应用程序?

您可以从这里下载代码https://rapidshare.com/files/458792519/test.rar (包括liboauth的代码)

Answer 1

为了总结OP注释中的对话，我下载了示例代码并针对它运行了nmake (makefile.nt)。我确实得到了链接器错误，但是缺少的符号来自Win32库。我将user32.lib和gdi32.lib添加到makefile中的LIBS列表中，然后它干净地链接(构建使用了VS2005、VS2008和VS2010)。

正如OP所指出的，在添加这两个额外的库时，它也会干净地链接。我不清楚这将如何帮助解析libeay32.lib中的这些符号。因此，我怀疑，对make文件的更改导致了对所有.obj文件的完全重建和编译。完全干净的构建导致了它的工作。因此，也许(我只是猜测) .obj文件最初编译得不正确(编译器可能对链接器没有很好的工作？)整个重建使一切都保持一致。
