I'm trying to build C++ project (mapserver). It depends on some other projects.
When I run nmake
, it shows many errors like this:
...
LIBCMTD.lib(getenv.obj) : error LNK2005: _getenv already defined in MSVCRT.lib(MSVCR90.dll)
LIBCMTD.lib(tolower.obj) : error LNK2005: _tolower already defined in MSVCRT.lib(MSVCR90.dll)
LIBCMTD.lib(fflush.obj) : error LNK2005: _fflush already defined in MSVCRT.lib(MSVCR90.dll)
MSVCRT.lib(MSVCR90.dll) : error LNK2005: __strnicmp already defined in LIBCMTD.lib(strnicmp.obj)
...
I know it is caused by /MD
and /MT
options when they differs from project to project.
I checked all project's build files and have found only one with /MT
. I changed it to /MD
and rebuilt it, but error remained.
How to find a library caused this error?
Thanks for all!
P.S. Project list:
curl-7.24.0
expat-2.0.1
freetype-2.4.8
gdal-1.9.0
gdwin32
jpeg-6b
lpng158
mapserver <-- main
postgresql-8.4.9
proj-4.7.0
regex-0.12
zlib
The solution turned out very simple.
I run dumpbin
on each library that main program uses. One of them was compiled with
/DEFAULTLIB:"LIBCMTD"
that means /MT
option.
P.S. It is interesting, that build file didn't contain /MT
or /MTd
options. Instead, it included
<win32.mak>
with
!IFDEF NODEBUG
cvarsmt = $(noansi) -D_MT -MT
cvars = $(cvarsmt)
cvarsdll = $(noansi) -D_MT -D_DLL -MD
!ELSE
cvarsmt = $(noansi) -D_MT -MTd
cvars = $(cvarsmt)
cvarsdll = $(noansi) -D_MT -D_DLL -MDd
!ENDIF
The makefile contained
CFLAGS= $(cflags) $(cdebug) $(cvars) -I.
I replaced it with
CFLAGS= $(cflags) $(cdebug) $(noansi) -D_MD -MDd -I.
and all begun to work.
