[Ipopt] Help with IPOPT linking problems on Windows MSVC/Intel C++

Sat Aug 23 13:04:10 EDT 2008

Hey guys:

Based on Damien's suggestion I tried different permutations of nodefaultlib
to no avail.  I am taking one last crack at linking to this in a debug build
before getting into the building world (release is working sufficiently for
now I believe)
 * I changed the /Code Generation/Runtime Library to Multi-threaded Debug
(/MTd)  from the default dll version
 * I link to just libipopt.lib (adding in others didn't seem to help).
 * without setting any /nodefaultlib I get a bunch of duplicates like the
following, all mentioned are from libcmt.lib such as:
1>LIBCMT.lib(invarg.obj) : error LNK2005: __initp_misc_invarg already
defined in LIBCMTD.lib(invarg.obj)
1>LIBCMT.lib(invarg.obj) : error LNK2005: __invoke_watson already defined in
LIBCMTD.lib(invarg.obj)

 * With setting /NODEFAULTLIB:libcmt I get a bunch of unresolved symbols:
1>cpp_example.cpp
1>Linking... (Intel C++ Environment)
1>xilink: executing 'link'
1>libipopt.lib(IpSumMatrix.obj) : error LNK2001: unresolved external symbol
__invalid_parameter_noinfo
....

 * With setting /NODEFAULTLIB:libcmtd I get 4 unresolved symbols:
1>LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other
libs; use /NODEFAULTLIB:library
1>libcpmtd.lib(stdthrow.obj) : error LNK2019: unresolved external symbol
__CrtDbgReportW referenced in function "void __cdecl
std::_Debug_message(wchar_t const *,wchar_t const *,unsigned int)"
(?_Debug_message at std@@YAXPB_W0I at Z)
1>libcpmtd.lib(xdebug.obj) : error LNK2019: unresolved external symbol
__malloc_dbg referenced in function "void * __cdecl operator new(unsigned
int,struct std::_DebugHeapTag_t const &,char *,int)"
(??2 at YAPAXIABU_DebugHeapTag_t@std@@PADH at Z)
1>libcpmtd.lib(xdebug.obj) : error LNK2019: unresolved external symbol
__free_dbg referenced in function "void __cdecl operator delete(void
*,struct std::_DebugHeapTag_t const &,char *,int)"
(??3 at YAXPAXABU_DebugHeapTag_t@std@@PADH at Z)
1>libcpmtd.lib(_tolower.obj) : error LNK2019: unresolved external symbol
__calloc_dbg referenced in function __Getctype
1>C:\working\libraries\etk\examples\test_etk_coin\Debug/test_etk_coin.exe :
fatal error LNK1120: 4 unresolved externals

* With Setting /NODEFAULTLIB:libcmt and then /NODEFAULTLIB:libcmtd (or a
superset of those) I get an enormous number of unresolved symbols

If anyone has any last minute suggestions on a permuation, I would love to
give it a shot.  Otherwise, do you suggest I try to make the windows
binaries with Visual Studio or MingGW instructions?  Which do you think is
easier to get working for building the 4 permutations of builds
(debug/release and multithreaded/multithreaded-dll)?  Also, do you expect
that I will have trouble with the multi-threaded dll build?  I am using /MDd
for my other libraries and am worried I may run into the opposite problem
changing those over.
