When i compile OpenSees with MSVC6,
i find all of these projects use option: "/ML" (Single-Threaded)

More details please refer to below link:
http://msdn2.microsoft.com/en-us/librar ... S.71).aspx

After i change all "/ML" options to
"/MD" (Multithread)
i still get below error messages.

libIEPCF90.lib(2696199.obj) : error LNK2001: unresolved external symbol _errno
libIEPCF90.lib(269697.obj) : error LNK2001: unresolved external symbol _errno
libIEPCF90.lib(2696173.obj) : error LNK2001: unresolved external symbol _errno
libIEPCF90.lib(269697.obj) : error LNK2001: unresolved external symbol ___mb_cur_max
libIEPCF90.lib(269697.obj) : error LNK2001: unresolved external symbol __pctype

compiler: MSVC6 + SP6
OS: WinXP + SP2

can anyone give me some help or tips?

Thank you in advance.

i think the reason is the link option of libIEPCF90.lib is also "ML", but I don't have the source code.

if i add "/force" to the link option, it will build an exe file.
But i think it maybe cause some unknown problems.

now i get it!
just change the content of this file to below code, and add to my project
OpenSees/SRC/win32/VC2005errno.cpp

Code: Select all

extern "C" 
{
    int __mb_cur_max;
    unsigned short* _pctype;
    int errno;
}
