[Ipopt] libc.lib

[tibor.vansa]

Hi,

I use the visual studio 2005 to compile the IPOPT, and I get a link error:
fatal error LNK1104: cannot open file 'libc.lib' in project "hs071_cpp". I
tried to fix this problem by setting "properties->Linker->input->Ignore
Specific Library" as /NODEFAULTLIB:libc.lib. But it still doesn't work well.

========== Rebuild All: 4 succeeded, 1 failed, 0 skipped ==========

I try both release, debug mode, I try to modify makefile.vc to 

CFLAGS = -DUSE_CLOCK -DMSDOS -DNO_ONEXIT -MTd -DNO_My_ctype -DNO_ISATTY

I also google out solution

1. in Project / Settings

    - In Object/Library modules, you added smi.lib

    - ensure "Ignore all default libraries" is *un*checked.

    - in Project Options add manually  /nodefaultlib:"libc" 

    - add a new .c file in your project (any name)

    - in this .c file, put a single line:

int errno= 0;


2. Do Build => Rebuild all

3. You may have a problem with precompiled headers
=> In Project / Settings / C/C++, Category "Precompiled headers"
click the radio button "Not using precompiled headers"
And Rebuild all again.

Nothing works, pls help

Thx
