[Coin-ipopt] Problem with Compiling hs071 in IpOpt 3.3.1 till 3.3.3 under VS 2005

[Froidure, Tristan A]

Hi All,

I couldn't get to compile the MSVisualStudio v8 project entirely, as
some libs seems to conflict with each other. 

I used VS 2005, and have also VC6 installed.

More precisely, after getting all third party code and having created
vcf2c.lib, I was able to compile all the libs in the VS project
(Blas,Lapack,HSL, and finally IpOpt). 

However the example couldn't link, and I got:

1>LINK : fatal error LNK1104: cannot open file 'libc.lib'

As this is usually no big deal, I added libc.lib to : Configuration
Properties->Linker->Input-> Ignore Specific Library

I then get the following link errors:

1>LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of
other libs; use /NODEFAULTLIB:library
1>vcf2c.lib(open.obj) : error LNK2001: unresolved external symbol _errno
1>vcf2c.lib(wrtfmt.obj) : error LNK2019: unresolved external symbol
_errno referenced in function _w_ed
1>vcf2c.lib(endfile.obj) : error LNK2001: unresolved external symbol
_errno
1>vcf2c.lib(sfe.obj) : error LNK2001: unresolved external symbol _errno
1>vcf2c.lib(fmt.obj) : error LNK2001: unresolved external symbol _errno
1>vcf2c.lib(wsfe.obj) : error LNK2001: unresolved external symbol _errno
1>vcf2c.lib(err.obj) : error LNK2001: unresolved external symbol _errno
1>Release/hs071_cpp.exe : fatal error LNK1120: 1 unresolved externals

Removing LIBCMT is no solution, and gives the same error.

Hence, it seems that the old libs used by  vcf2c.lib and created by
nmake are conflicting with the new libs used by visual studio.

I compiled vcf2c.lib directly under VS 2005 (and not VC6 or lower), but
could not get around the conflicts between the C Run Time libraries....

I made sure that all the projects are Multi-Threaded, and really don't
see what to do from there.

Could anyone help? I have a wonderfull math problem to solve numerically
and can't wait to go to the best part of the job....
