499.0. "Developer Studio linker problem on Alpha" by VAOU09::LAM () Fri Apr 18 1997 15:09

    I have installed Developer Studio 5.0 on my NT4 Miata. I am trying
    to check out the SDK\ISAPI samples but keep running into a linker
    problem:
    LIBCd.lib (crt0.obj) error LNK2001: unresolved external symbol main
    AlphaDbg/IS2WCGI.exe : fatal LNK1120: 1 unresolved external
    I have recreated a new configuration in project, but without success.
    I am able to build using nmake from the command prompt by doing 
    set CPU=ALPHA.
    The .mak file generated by Developer Studio has X86 references in it.
    Is there a way I can set the CPU type inside Developer Studio ?

	the following response is from Vadim Paretsky 1. The IS2WCGI sample has a linker option that says /entry:"_DllMainCRTStartup@12". This decorated name is Intel specific. When creating an Alpha configuration from an Intel configuration the IDE doesn't do translation of /entry: linker options into appropriate Alpha names. That should be done by the user. (To find this option in the IDE, click Settings on the Project menu. Then click the Link tab, and click Output in the Category box.). The Alpha name in this case should be "_DllMainCRTStartup". This should solve the "unresolved external symbol main" problem. 2. The X86 references in the makefile generated by the developer's studio apply to Intel configurations only (linker options /machine:IX86 or /machine:I386) . Alpha configurations cloned from Intel configurations or created from scratch will have /machine:ALPHA. No action from the IDE is necessary.
