[Mingw-users] unknown reference in msvc import library

[Gilgamesh N. <Gil...@el...>]

Hi all,

I'm trying to use MinGW (using Cygwin as evironment) to build against a 
MSVC generated ingres.lib
It almost works but during the linking phase it cannot find a reference 
to '_chkstk'.

The original commandline that the IDE wants to use is this:

link /NOLOGO /SUBSYSTEM:console /ENTRY:mainCRTStartup /OUT:tt.exe 
/MAP:tt.map D:\ingres\ingres\lib\abfmain.obj 
D:\ingres\ingres\abf\xltt\tt\abextract.obj 
D:\ingres\ingres\abf\xltt\tt\start.obj 
D:\ingres\ingres\abf\xltt\tt\blah.obj 
D:\ingres\ingres\abf\xltt\tt\10010.obj shell32.lib msvcrt.lib libc.lib 
kernel32.lib user32.lib mpr.lib advapi32.lib netapi32.lib libcmt.lib 
D:\ingres\ingres\lib\ingres.lib

After it's rewritten this is the commandline that I use to build 
(libc.lib and libcmt.lib get dropped because I couldn't find a 
replacement for them and as far as I can tell they belong to MSVC itself 
so I was hoping that MinGW replaces their functionality):

/usr/bin/gcc -mno-cygwin -mconsole \
   -o tt.exe /ingres/ingres/lib/abfmain.obj \
   /ingres/ingres/abf/xltt/tt/abextract.obj \
   /ingres/ingres/abf/xltt/tt/start.obj \
   /ingres/ingres/abf/xltt/tt/blah.obj \
   /ingres/ingres/abf/xltt/tt/10010.obj \
   -lshell32 -lmsvcrt -lkernel32 -luser32 \
   -lmpr -ladvapi32 -lnetapi32 \
   /ingres/ingres/lib/ingres.lib

And this is the output it generates:

/ingres/ingres/lib/ingres.lib(abrtxio.obj)(.text+0x22c0):abrtxio.c: 
undefined reference to `_chkstk'
/ingres/ingres/lib/ingres.lib(abrtxio.obj)(.text+0x2a65):abrtxio.c: 
undefined reference to `_chkstk'
/ingres/ingres/lib/ingres.lib(abrtcall.obj)(.text+0x1546):abrtcall.c: 
undefined reference to `_chkstk'
/ingres/ingres/lib/ingres.lib(abrtnqry.obj)(.text+0x1096):abrtnqry.c: 
undefined reference to `_chkstk'
/ingres/ingres/lib/ingres.lib(abrtutil.obj)(.text+0x9):abrtutil.c: 
undefined reference to `_chkstk'
/ingres/ingres/lib/ingres.lib(abrtrw.obj)(.text+0x485):abrtrw.c: more 
undefined references to `_chkstk' follow

Unfortunately this is a proprietary product so I can't recompile 
ingres.lib with MinGW. The only thing that looks like _chkstk I can find 
is in libgcc.a but apparantly it doesn't want to get used and I can't 
figure out why(if it could be used at all).

Another thing I tried was generating libingres.a using reimp and digging 
around in the DLL's that are supplied with Ingres. But the approach used 
here (rewriting commandlines) works best as far as I can tell.

I hope somebody can shed some light on this.
