Thanks for your reply!

I found the stackoverflow reference but did not fully understand or could not implement it successfully..

Have you compiled your grid object on a windows machine? If so, could you provide a step-by-step instruction?:-)
Simpler question, do you have the libc.lib file in your Microsoft Visual Studio/VC/lib folder?

Since in my first post I assume the problem with missing library files due to older versions of Visual Studio, I am trying to run the helloworld examples in Pd\pd-extended\doc\tutorials\externals-howto\example1. Even here, I run into problems

Using the Visual Studio compiler:
LINK : fatal error LNK1561: entry point must be defined
--> I checked the code, places the m_pd.h file in the same directory but still no success...

Using the MingW and Sysm compiler (with appropriate environment vars set):
gcc.exe: error: CreateProcess: No such file or directory
--> gcc.exe is to be found in my folder C:\MinGW\bin to which I have pointed the environment variables and rebooted my machine...

Anyone? Anything?

Hello,

I created a new thread as the older post [Problem compiling on windows] (http://forum.pdpatchrepo.info/topic/967/problem-compiling-external-on-windows/16) seems to have ended and my problem has a different nature.
Moreover. I have not been able to find an answer on the puredata sites (puredata.info or puredata.org).

My problem:

My end goal is to play with the 'grid' external in pd-extended/externals/unauthorized/grid but since I do not get this one working and I have never compiled an external before I started with the simpler tutorials in Pd/doc/6.externs.

My steps and error are as follows:
**1. **Adap path in 'makefile' in Pd/doc/6.externs to 'C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC'
(this path contains a /lib folder with .lib and .obj files on my machine)
**2. **Start ( Admin) Visual C++ 2008 64-bit command prompt
**3. **Locate directory Pd/doc/6.externs
**4. ** run 'nmake pd_nt' command
**5. ** gives error in locating the libc.lib file
(LINK: fatal error LNK1181: cannot open input file 'C:...\VC\lib\libc.lib'

When I remove this instruction from the makefile, I does not find the kernel32.lib file also.
When I finally remove the former instruction, I get an error creating the library obj1,lib and object obj1,exp as I have 6 unresolved external symbols ex. obj1.ob : error LNK2019: unresolved external symbol __imp_post referenced in function obj1_float

Could someone help me solve these issues and help me succeed in making this external work?
Then, any additional explanation in getting grid to work afterwards?

Any additional info regarding Pd's treatment of externals/libraries etc is appreciated as well.. I just can't get a grip on it,
