<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3
face="Times New Roman"><span style='font-size:12.0pt'>I am trying to get the
IPOPT samples running in MSVC or Intel C++ and am running into linking
errors. Here are my steps:<br>
<br>
1. Downloading the binaries available on:<a
href="http://www.coin-or.org/download/binary/OS/"><span class=icon>http://www.coin-or.org/download/binary/OS/</span></a>
Note that the only binaries in: <a
href="http://www.coin-or.org/download/binary/Ipopt/">http://www.coin-or.org/download/binary/Ipopt/</a>
are for linux64.<br>
a. (BTW, as a general consideration I would say that people may be
overestimating the applicability of cygwin vs. the native Intel or microsoft
compilers when on windows. Getting a development environment working with
an optimizing compiler on cygwin is very difficult).<br>
2. The sample program I am getting is from the source in Ipopt-3.4.2. I
am trying out the cpp_example.cpp mentioned in: <a
href="http://www.coin-or.org/Ipopt/documentation/node32.html">http://www.coin-or.org/Ipopt/documentation/node32.html</a><br>
3. Since the makefile for this is for cygwin, I need to create my own. .<br>
a. I first added the 3 source files into a new project<br>
b. I ensured that the include path to the headers in the binary
distribution and the libraries directory were set properly.<br>
c. I added libipopt.lib to the linker inputs.<br>
4. I hit compile. All of the source compiled fine, but when linking, it
stated that a whole bunch of functions were already defined in core libraries
such as: MSVCRTD.lib. See notes below for some examples of these.<br>
5. To see if it would help, I added the names of the libraries to the
"ignore specific library" list in the linker input options. No
luck.<br>
6. I tried with Intel C++ vs. MSVC. No difference.<br>
7. I tried the "no default libs" selection in the project. A
million unresolved errors<br>
8. I tried opening the example that came in the binary distribution: called
osTestCode.<br>
a. Had a different link error for a library that wasn't in the binary
libs directory: 1>LINK : fatal error LNK1181: cannot open input file
'libifcorert.lib' <br>
b. That probably is an unrelated error, but why isn't this in the
distribution, and does it have anything to do with the empty IFORT directory in
the libs?<br>
<br>
Can anyone help? Below is a subset of the linker output to get the point:<br>
