Hello,
I'm trying to use CDT w/ Cygwin (Platform: Windows + Eclipse). My
HelloWorld.cpp compiles correctly using g++ from Cygwin, but I don't know
how to reference g++ in the make file for Cygwin.
This is the makefile for MinGW..
main : main.o
g++ -o main main.o -L C:/MinGW/lib/gcc-lib/mingw32/3.2.3/lstdc++
main.o : main.cpp
g++ -ggdb -c main.cpp
all :
${MAKE} main
clean :
-del main.o
How do I change it to make it work with Cygwin?
Thanks in advance,
FBM

A lot of people get confused about what MinGW and Cygwin are. Let me
breafly explain each so you get a better picture:
Cygwin: Cygwin is a porting technology. It allows Unix programs to be
recompiled as their are on Windows. So, what you have in the end is a
Windows based executable of a Unix program such as GCC, GDB, make, etc.
MSys: MSys is a project a MinGW. Same goals as Cygwin using almost the
same approach.
MinGW: Finally. We have MinGW. MinGW is a package composed of several
items, including GCC, make and other tools and libraries which allows
you compile C/C++, Java and other languages into native Windows
executables. MinGW does NOT use any porting technology. Several
modifications were made into the source code so it will compile natively
on Windows. Also MinGW includes many crucial components such as system
headers, libraries, etc to compile Windows programs succesfully.
Keep in mind that Cygwin ALSO includes MinGW as an optional component
since is the only project I'm aware of that lets you compile Windows
programs on Windows based on GCC.
So, answering your question it should be exactly the SAME. No
modifications should be made to the source code nor the makefile.
Hope this helps.
Regards,
Emiliano

Hi!
just a short additional comment to your makefile, perhaps important for
further
programming stuff.
You should use the -L flag if you want to pass more library search paths
(like e.g.
"-L/usr/local/include/...") to the compiler, your "-L" is obsolete.
Additionally, as far as I know, you don't have to add "-lstdc++", it's
added
automatically.
Related to your last question: I don't know any solution for this task, at
least not
with standard tools.

I never tried it before. But I think it might be possible. You need to
exec make remotely using rexec or ssh. rexec should be easier to setup.
You will also need samba or other file sharing protocol to remotely edit
files on the Linux box.
Hope this info helps
