[OS] Using OS with Visual Studio and doing transformations

[Stefan.Hackmann at rwe.com]

Hi,

I would like to use COIN OS to call
different linear solvers in a unique
way.
I checked out the current version of OS from
https://projects.coin-or.org/svn/OS/trunk
and opened .\OS\MSVisualStudio\v9\OS.sln
with Visual Studio 2008. First of all the IDE
wants to convert the project. That's strange
from my point of view, since v9 project should
suit the 2008 version. However, all vcproj-files
have been converted. Now, building the complete
solution fails for projects OSSolverService and
OSTest, since external symbols are missing:

Error   420     error LNK2019: unresolved external symbol "public: void __thiscall LAP::TabRow::print(class std::basic_ostream<char,struct std::char_traits<char> > &,int,int const *,int)" (?print at TabRow@LAP@@QAEXAAV?$basic_ostream at DU?$char_traits at D@std@@@std@@HPBHH at Z) referenced in function "protected: void __thiscall LAP::CglLandPSimplex::printTableau(class std::basic_ostream<char,struct std::char_traits<char> > &)" (?printTableau at CglLandPSimplex@LAP@@IAEXAAV?$basic_ostream at DU?$char_traits at D@std@@@std@@@Z)        libcgl.lib      OSTest

Any ideas, how I can fix this?

Moreover, I would like to know how I can use
the libraries to import and export files, so to do
a pure conversion on file basis, e.g. mps->OSiL, OSiL->mps,
lp->OSiL, OSiL->lp, lpr->OSrL, OSrL->lpr, without calling a solver.

Many thanks for your help,

Regards,
Stefan
