Running the C program of the wind module


I have been trying to run the SAM's C code generated in command prompt. I have used the following command

gcc -o Golden Golden.c

Golden is my file name. However, I have received the error of "undefined resources" which is mostly related to the sscapi.h header file.
Could you please help me about this?

Dear Mohammad,

Please be sure that you are using the same operating system to generate the code from SAM and to run the C program. For example, if you are running the C program in Linux, you should use the Code Generator in the Linux version of SAM to be sure that the code package it creates is for the right operating system.

Best regards,

I just tested the win32 version of the 2018.11.11 release with the default PV/Residential C code generation using mingw 32 bit version on Windows 10. The folder with the code generation has the sscapi.h and appropriate ssc.dll files to run. I matched the results in SAM using the commands in the attached image.

Looking at your command, you are missing the -lssc from the build statement.

For reference, the generated Makefile for the C build is:

ifdef SystemRoot
RM = del /Q
EXT = .exe
CIFLAGS = -I.. -L.
LFLAGS = -lssc
#x64 SET PATH=c:\MinGW64\bin;%PATH%
#win32 SET PATH=c:\MinGW\bin;%PATH%
CCCOMP = gcc
PF = $(shell uname)
ifneq (,$(findstring Darwin, $(PF)))
VERS = $(shell sw_vers -productVersion)
EXT = .dylib
ifneq (,$findstring(Linux, $(PF)))
CIFLAGS = -I.. ./
EXT = .o
RM = rm -f
CCCOMP = gcc
LFLAGS = -ldl
PROJ_NAME = untitled
all :
clean :
@echo "Please check the settings for your system.Your system may not be supported.Please contact"

Let us know if you still are running into issues with the C code.

SAM comes with different ssc.dll files for 32-bit ( sscx32.dll and 64-bit ssc.dll Windows operating systems. If you are compiling a 32-bit C program, you will need to use the 32-bit version of SSC.dll.

For a 32-bit C program, you should run the code generator from the 32-bit version of SAM ( C:/SAM/2018.11.11/win32/sam.exe).

You can then run the mingw32-make from with the generated code instead of using the gcc command.

To use the gcc command instead on Windows 10 with mingw and mingw64 installed, you can do the following from a windows command prompt:

For 32-bit

  1. Start the 32 bit version of SAM 2018.11.11 as described above.
  2. Use the Code Generator to generate the C code in a folder like c:\SAM_c_code.
  3. Open a windows command prompt go to the folder containing the generated code.
  4. Assuming that the 32-bit version of MinGW is installed in C:\MinGW, type:

set path=%PATH%;c:\mingw\bin
gcc -I.. -L. -oGolden Golden.c -lsscx32


  1. Start the 64 bit version of SAM 2018.11.11 as described above.
  2. Generate the C code in c:\SAM_c_code.
  3. Open a windows command prompt and change to the folder.
  4. Assuming the 64-bit version of MinGW is installed in C:\MinGW64:

set path=%PATH%;c:\mingw64\bin
gcc -I.. -L. -oGolden Golden.c -lssc
