By Jove, I believe you have it!!!I ran the test case under cygwin with LIB_PATH set. The compile was successful and the build ran. I have not tried the g++ -L/<path>/lib yet. So that's in the hopper to work on.
Is there any way of documenting this, and whatever else, so that others have some guidance? I would be more than willing to provide something, but I have so little knowledge that I don't know what good it would do. But, if you'd like I can do something.
And, is there any way of including this, and any other necessary things, in the IDE project properties? After several years (and I do mean years) of asking the question of how to do a build and execute under NB, only Pieter provided an answer. As a general complaint, this shouldn't have happened. And the fix is so trivial. Again, I'd be willing to help, but I haven't looked as the NB source code and I don't know where to begin (or how to make changes).
And the last request, anyway of making it possible to compile a single file rather than forcing the Build to compile all files to create object object files for the build. For my toy projects, this is not an issue. But for larger projects, with hundreds or thousands of files, this could be a stumbling block.
I suspect that a compile of a single file.cpp would involve passing the knowledge of which file to compile to the compile property, perhaps something that allows g++ -c $i to make sense, where $i is the file being compiled, that way when a file.cpp is to be compiled the file name is passed to the compile command.
The Cygwin commands used are: > LIB_PATH=/cygwin/usr/lib/ > ./<path>/netbeans64.exeIf there is any help that I can do, please tell me, but note that there is a long learning curve in understanding a project that is been ongoing for (at least) two decades.
All in all, NB is an excellent IDE. And thank you for everyone's effort in making it so.

isn't there something like a LIB_PATH in the cygwin environment? met vriendelijke groet Pieter van den Hombergh Op do 20 mrt 2025, 21:35 schreef slipbits <slipb...@slipbits.com>: 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; art On 3/4/2025 3:22 AM, Ulf Zibis wrote: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". -Ulf Am 04.03.25 um 06:12 schrieb slipbits: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. art On 3/3/2025 4:33 PM, Ulf Zibis wrote:Hi Art, I now learned, that the `cc` option `-s` means "strip" (I copied the command from elsewhere).

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++. art On 3/2/2025 6:07 PM, Ulf Zibis wrote:Hi Brad, it seems you have good luck with it.
