[Mingw-users] using Unix static C libraries

[Deepak C. <dch...@gm...>]

Hello,
   I was under the impression that if I have a an achive file (.a)
that I use in Linux, I can can use the same file with MinGW --
basically use the same call that I would use in Linux. MinGW is
recognizing the library (does not produce a no such file error) and
using "ar t ..." on the .a files does show all the .o files), but it
gives "unrecognized reference: " errors for all the functions from the
library that I am using. Here are the specifics:

Here is the Linux command (works in Ubuntu):
gcc mathfuncs.c main.c -lm -lsundials_cvode -lsundials_nvecserial

I executed the same command using MinGW, and I get the following errors:

C:\Users\Deepak\AppData\Local\Temp/ccGBkQwd.o:cvodesim.c:(.text+0x179):
undefined reference to `N_VNew_Serial'
C:\Users\Deepak\AppData\Local\Temp/ccGBkQwd.o:cvodesim.c:(.text+0x23e):
undefined reference to `CVodeCreate'
C:\Users\Deepak\AppData\Local\Temp/ccGBkQwd.o:cvodesim.c:(.text+0x2a2):
undefined reference to `CVodeMalloc'
...several other similar errors....
collect2: ld returned 1 exit status

The .a files are in C:/MinGW/lib, and since there is no "cannot
find..." error, I am assuming that the library files are found.
Is it possible that the exported symbols have changed when using MinGW?
What do I need to do to use the .a files?

Thanks.
