FYI, this issue turned out to be due to the linking to non-debug MSVCR90.lib in: 1. iconv project. - had to make sure that MDFlags in iconv makefile also changed to /MDd when debug was requested. 2. pthreads - changed /MD to /MDd in flags to each .c compilation to .obj, also added /MDd in final linking and removed explicit linking with libcrt.lib - because /MDd already does it with debug crt.

additional info:

it seems even after DEBUG build, my executable is looking for non-DEBUG version of MSVCR90.dll

--------------------------- mserver5.exe - Unable To Locate Component --------------------------- This application has failed to start because MSVCR90.dll was not found. Re-installing the application may fix this problem. ---------------------------

when i copy the set of MSVCR90.dll and manifest into debug directory, i get the error shown below.(my prior message)

here are my build commands that i use for all modules:

nmake /nologo BITS64=1 NEED_MX=1 DEBUG=1 HAVE_ICONV=1 HAVE_MONETDB4=1 HAVE_MONETDB5=1 HAVE_PYTHON=1 "prefix=%BUILDTOOLS_PREFIX%"

nmake /nologo BITS64=1 NEED_MX=1 DEBUG=1 HAVE_ICONV=1 HAVE_MONETDB4=1 HAVE_MONETDB5=1 HAVE_PYTHON=1 "prefix=%BUILDTOOLS_PREFIX%" install

...

Does anyone know why i may be getting this error:

Runtime Error!

Program: C:\monetdb\build\bin\mserver5.exe

R6034

An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information.

----------- also is there a 'clean' target for make? i don't see it anywhere.
