Help - Building DLLs

["Giuliano Garuti" <giuliano dot garuti at sunriseprotel dot com>]

Recently I purchased the Cygwin v1.0 software to compile Linux C source
files in the Windows NT environment. But something went wrong. So I decided
to face the problem by steps.

First I created 2 simple source C files named "myprog.c" and "mydll.c"
(these files are attached to the e-mail). Then I executed the subsequent
commands in the shell:

gcc -c myprog.c

gcc -c mydll.c

ld --dll -o mydll.dll mydll.o -e _mydll_init@12 -d -cref -shared --base-file
mydll.base

dlltool --base-file=mydll.base --output-def mydll.def --output-exp
mydll.exp --dllname mydll.dll

ld --dll -o mydll.dll mydll.o -e _mydll_init@12 -d -cref -shared --base-file
mydll.base mydll.exp

dlltool --base-file=mydll.base --def mydll.def --output-exp
mydll.exp --dllname mydll.dll

ld --dll -o mydll.dll mydll.o -e _mydll_init@12 -d -cref -shared mydll.exp

dlltool --def mydll.def --dllname mydll.dll --output-lib mydll.a

gcc -o myprog myprog.o mydll.a

At the end of this process this error message is displayed:

myprog.o(.text+0x26):myprog.c: undefined reference to 'do_nothing'
collect2: ld returned 1 exit status

What do you suggest I do to resolve the problem?

The software is very important as it will and can aid me in developing my
research. BUT it does not work and I need to know what I am doing wrong or
why the software is not working. Please respond to my email, my questions.

Please answer directly using my email.

Thanks for your attention.

Best Regards.
