Hi again

Thanks for the patience.

I don't know if I got what you meant so I tied the following commands

a) mprep addtwo.tm -o addtwotm.c  (page 48 of MathLink Development in C)
b) then I try

C:\msys\1.0\home\eduardo\MATHLI~1\addtwo>g++
-Ic:/msys/1.0/home/eduardo/include
addtwotm.c -o addtwo.exe -Lc:/msys/1.0/home/eduardo/lib -lML32i3 -lML32i2
-lML3
i1
C:\Users\eduardo\AppData\Local\Temp\ccelsS8E.o:addtwotm.c:(.text+0x15b):
undefi
ed reference to `GetStockObject@4'
collect2: ld returned 1 exit status

c) and 

C:\msys\1.0\home\eduardo\MATHLI~1\addtwo>g++
-Ic:/msys/1.0/home/eduardo/include
addtwo.c -o addtwo.exe -Lc:/msys/1.0/home/eduardo/lib -lML32i3 -lML32i2
-lML32i

C:\Users\eduardo\AppData\Local\Temp\cc2EukU7.o:addtwo.c:(.text+0x3a):
undefined
reference to `MLInitializeIcon'
C:\Users\eduardo\AppData\Local\Temp\cc2EukU7.o:addtwo.c:(.text+0x96):
undefined
reference to `MLMain'
collect2: ld returned 1 exit status


Which one is the right one?  The Documentation is too convoluted and there
is no help with cygwin.

Many thanks

Ed

Hi,

why are you giving

> addtwo.c addtwotm.c


both files? You mprep addtwo.tm into addtwo.c and
then use only addtwo.c to compile. This should kill the
multiple references error message.

Cheers
Patrick
