I have tried to build using cygwin in a Win11 environment.
The Win PATH variables contains the path to the location of the shared
libraries, C:/cygwin64/lib/gcc/x86_64-pc-cygwin/12/.
The build command I use is:
C:\cygwin64\bin\g++.exe -c *.cpp
And when I use cygpath -u 'C:\cygwin64\bin\g++.exe'
becomes/usr/bin/g++.exe -c *.cpp, and /usr/bin/g++.exe exists.
On a build I get:
C:/cygwin64/lib/gcc/x86_64-pc-cygwin/12/cc1plus.exe: error while loading
shared libraries: ?: cannot open shared object file: No such file or
directory
Doing cygpath -w 'C:/cygwin64/lib/gcc/x86_64-pc-cygwin/12/' becomes
/usr/lib/gcc/x86_64-pc-cygwin/12 and
/usr/lib/gcc/x86_64-pc-cygwin/12/cc1plus.exe exists.
My guess is that g++ can't find cc1plus.exe, or that cc1plus.exe can't
find the shared libraries, but I don't understand why not. PATH includes
the shared libraries, and I suspect that cc1plus.exe either has the path
hard coded or looks at PATH.
The email below that Ulf was able to use Netbeans in a Linux environment
to, at least, build, clean and execute code, but I can't seem to get the
same result in Windows. Does anyone know why?
As a separate question, is there any reason that compiling a single file
is not allowed?
thanks;

Hi Art,
yes, I can build, clean, run and debug my Project with the given
commands.
"Compile" is grayed out either here, regardless, what is put in the
Editor->"Compile Commands" field.
I guess, I could also use `make install` and `make clean` for "Build"
and "Clean".
For debugging, `gdb` must be installed.
I guess on Windows you must use Windows style commands.
And I think, there is no limitation for the length of the commands, so
no need for line continuation characters.
But you can execute multiple commands, if you put them in separate
lines as you can see in my example.
Yes, I compile into the project directory and move the generated
object into the plugin directory of my application at same time with
"Build". I also could use `cc ... -o /home/ich/.jpilot/libmedia.so".

Hi Ulf;
Does it work? If so, great. If not, not so great.
You have one advantage over me, an integrated environment (Linux). I
have a mixture of Windows and Linux, and in this environment without
feedback, I'm lost.
I notice your compile command (cc -ggdb -fPIC -shared) puts the
generated object file into the same directory as the header and
source files. Was that your intent? One issue that I have is that I
want to put the generated object files in another directory. In order
to do that, I have to pass the file name to one of the g++ parameters
(g++ -c -o obj/<filename>) and there are no directions as to how to
do this.
I guess a common issue would be a compile/build command that is
large. I haven't tried this so I don't know if a line continuation
character ('\' in Linux) has to be provided or whether the input
'line' extends to as large as is needed. Another feature that needs
experimentation.
But, if it works for you then that is great.

Hi Art,
I now learned, that the `cc` option `-s` means "strip" (I copied the
command from elsewhere). When I omit it, the debug symbols, created
by option `-ggdb` were not removed again from the binary.
Now, what a surprise, I can debug my code with NetBeans. Wow, that's
great.
So now I have:
Compile Commands:
cc -ggdb -fPIC -shared
Build:
cc -ggdb -shared -fPIC media.c -o libmedia.so
mkdir -p /home/ich/.jpilot/plugins
mv libmedia.so /home/ich/.jpilot/plugins/
Clean:
rm -r /home/ich/.jpilot/plugins
Run:
jpilot -d

Hi Ulf;
Way back in the bottom of this email, I asked about C/C++ support.
Some answers followed.
I work in a Windows environment and have cygwin (a Windows Linux)
with mingw and gcc.
There is no documentation of what is required for entries in
"Compile Command", "Build", "Clean" or "Run". So, I've tried
different versions of paths to reference the gcc toolset. So far,
none have worked, except for "Clean". What is more than puzzling is
how to specify what is being compiled to the compiler. In my case,
I would like to use something like "g++ -c -o obj/?" where the "?"
is a question as to how I can specify that the object file created
goes to a separate directory.
This means that I have given up. My current procedure is to use g++
directly in a script or by typing in a bash shell. I use:
g++ -c obj/$1 $1 in a bash script to compile a file, and
for i in *.cpp; g++ -c obj/$i.o $i 2>> error.log; done. To
compile everything and save the errors.
Don't really know what else to do. There are no descriptions to
follow, nothing to say "hey, this is the correct way to do things",
and there hasn't been since NB 8.0. Without any guidelines it
becomes a matter of experimentation. And when you run out of ideas,
why then, your done.
As a suggestion, if you are having undue difficulty then separate
the compile, build, run and debug tasks from NB and do it
externally. That allows you to go forward. Otherwise you may be
experimenting for a bit.
As another note, for referencing CCLS or clangd, go to tools ->
options -> C/C++. I have no idea whether it works but I use
"C:\cygwin64\usr\clangd\bin\clangd.exe". Note that there is a
selection you have to make at the bottom, "Preferred server".
And one more (snarky) comment. In my C++ setup, the "Run -> Compile
file" selection is grayed out, so even if I wanted to, I can't work
effectively.
As to debug, well, since I have never gotten compiles and builds to
work, I've never gotten as far as debugging. But if I had, there is
no information as to what debugger is being used, this effects the
compile phase, and I don't think that there is an option to allow
specification of what debugger you want. There is also, no way to
specify search paths, which in my case means that I have to change
my Windows environment PATH to include cygwin paths.
I've been asking for help for C/C++ setup for years, yep, years. I
would be willing to take a try at developing documentation but I
have never been able to get it to work so I can't write about
anything but failures.
If this all sounds like I'm frustrated, well, I am. And if it
sounds, or looks, like I'm not accurate in what I say, it's because
I don't know better. But, I truly do like NB, and I do think that
the people who are movers and shakers have done a great job, and
one which I would like to thank them for. But the developers
attention have shifted from C/C++.

Hi Brad,
it seems you have good luck with it.
I have set up a small C project with NB 24 on Ubuntu to build a
library. Package ccls is installed. Must i be somehow registered
in NB?
The build command is:
cc -s -ggdb -shared -fPIC media.c -o libmedia.so
When I set a breakpoint at some line and run "Debug", the program
does not stop at that line, and I don't see any variables.
How does that work?
Can someone tell me where the projects properties are saved?
I don't see a folder like .nbproject in my projects folder.
Regards,
Ulf

There is a plug-in: CPPLite Kit.
I am using NB23.
This kit needs either: ccls, or clangd.
I'm running on Linux and using ccls.
