Sorry this was my mistake. The compile command is
vlog sine.sv dpi_sin.c -dpiheader sin.h

Do you have a work library in the directory where you are calling vlog?
I do not use mingw compiler, I use the cygwin gcc
gcc version 5.3.0 (GCC)
see my compile log below:

Hi sue
I had resolved the work directory isuue ;)
you are using Questa 10.4c, I’m using ModelSim 10.1c, they require different compiler i guess?!
can i use gcc version 5.3.0 (GCC)? i do not know, i’ll try
In reply to saketa:
the gcc version does not matter. I don’t have installed the mingw compiler from Questa. It takes the cygwin gcc and this is 5.3.0.
In reply to chr_sue:
It does not work with ModelSim 10.1c, i must have questaSim 10
.4?
In reply to saketa:
What confuses me is the error message:
** Fatal: ** Error: (vsim-3828) Could not link ‘dpi_auto_compile.dll’: cmd = ’ C:\modeltech_10.1c\gcc-4.2.1-mingw32vc9\bin\gcc.exe -shared -o “C:\cygwin\tmp\ab doo@ABDOO-PC_dpi_4292\win32_gcc-4.9.0\dpi_auto_compile.dll” C:/cygwin/home/abdoo /work_dpi\auto_compile@\win32_gcc-4.9.0*.o -L"C:\modeltech_10.1c\win32" -lm tipli’
I do not see your compiled object (.dll in Windows, .o in Linux. It should not link to dpi_auto_compile.dll. This is correct.
The second thing is you have dpi_auto_compile.dll from 2 sources in the error message, one comes from the modelsim installation and the second one from cygwin. This looks like your setup is wrong.

In reply to saketa:
I was assuming the error appears during compilation. The vsim command needs to know where to look for the linked C-object (.dll for windows, .so for Linux). There is the switch -sv_lib. You have to point to the right place.
In reply to saketa:
the vsim command should look like this
vsim -sv_lib C:/Users/xx/example …
if your .dll file is available in C:/Users/xx/example
