Ok, this seems like a dumb question because MonoDevelop is getting more mature, so I'm sure I'm just missing it, but I looked around and all the questions about this subject seem to be about remote debugging or debugging on a Mac.
I'm using Ubuntu 10.04 Lucid Lynx, and I just installed MonoDevelop 2.2.1 from the software center.
I created a GTk# 2.0 project, added some widgets and code and everything seems to run fine. Then I added a breakpoint, and it shows up in my breakpoints window, and it says it's active, but the breakpoint never actually hits(stops execution and pulls me into the debugger).
I'm in Debug x86 mode, so I can't figure out what's going on.
Anyone have this happening/know what to do about it?
I'm having the same problem (also on Ubuntu 10.04) and found kind of a hack that is working for me. Instead of setting a breakpoint in the IDE (by clicking on the side or hitting F9), make a call to the System.Diagnostics.Debugger.Break() method in your code where you want the execution to break. After doing that, I am able to step through the code, use the immediate window, etc. Obviously, it's not a very good solution, but at least it's something.
To check whether you have a debugger installed, simply check whether the "Run" menu contains a "Debug" command.
You should be aware that Ubuntu ships a rather old version of Mono (2.4) which has no built-in "sdb" debugger, and its version of MonoDevelop 2.2 is patched to remove the sdb interface. To get semi-functional debugging, install the old "mdb" debugger - the mono-debugger and monodevelop-debugger-mdb packages, IIRC.
To get the best debugging experience (sdb), you need Mono 2.6+ and an unmodified MonoDevelop 2.2+. If you decide to build Mono from source, please read this and this first. Alternatively, you could use openSUSE, which has up-to-date Mono and MonoDevelop packages available.
What versions of Mono runtime and debugger are installed? I tried it with monodevelop 2.2 + mono 2.6 + debugger 0.0.0 under Windows and it works just like expected. Here is a quotation from mono's website, which may be helpful:
Mono comes with two Mono-specific debuggers: a hard debugger and a soft debugger, additionally, you can use the Unix GDB debugger with Mono to debug low level problems
...
Soft Debugger:
...
Moonlight, ASP.NET, Gtk#, iPhone and remote debugging supported
Maybe the problem is in a code? What do you mean by:
... (stops execution and pulls me into the debugger).

I'm trying to configure CLion with Cygwin, but I'm having trouble with CMake. The program says that the bundled version doesn't work in that environment and that the CMake from Cygwin is outdated (needs a newer version). However, I tried installing an independant CMake but then the program says it isn't compatible with Cygwin. How do I fix this?

I'm teaching a C++ programming class this semester. All of my students were able to successfully install/configure CLion without too much trouble. Most of them are on Windows boxes, Win7 and Win10.
In my instructions, I referred them to this video, which was the best I could find: https://www.youtube.com/watch?v=i2h_976SpV0
Some of the students were missing the debugger the first time they tried this. In the cygwin installer, the number of check boxes is enormous and many of the names are remarkably similar. When we went back through and re-ran the installer, in each case we were able to find a place where they had checked the wrong box.
So my recommendation would be re-run your cygwin installation after watching the video once through. Then go back to the frame in the video where he shows all his checked install options and very carefully compare your checked boxes against the presenter's.
Good luck!
I would like to install ColdFusion Builder 2 Update 1 as a Plug-in for Eclipse 4.3.
The install seems to work without errors but when I attempt to register my license code, I get an error dialog box that says:
"The chosen operation is not enabled."
None of the CFB features appear in Eclipse.
In some of the documentation that I've found it references installing to Eclipse 3.6.
Can CFB 2u1 get installed on Eclipse 4.3? If not, does someone know which version of Eclipse to use for CFB? Hopefully it is something recent or I'm doing something wrong for the install.
I don't know if it matters, but I'm running:
Windows 7 Pro 64-bit
16GB RAM
According to the ColdFusion Builder System Requirements page one needs Eclipse 3.7.1. Having tried to install it on versions later than that, failing, and talking to Adobe about it, they confirmed that one needs that precise version. More recent ones won't do. This is a bit subpar on the part of Adobe, but so be it.
I have done a little work on lazarus' free pascal. So when a client asked me to write an application for a mac, after the initial, "it can't be done" stage. (followed by an asp.net maybe stage) i thought about writing it using lazarus.
Question is. I have only a virtual machine running mac OSX, this means that i do not really want to develop on the mac. However, i just cannot seem to get the applications that i have written in lazarus on windows to work on the mac. I have tried the deployment using the Lazarus Wiki and the MACOS folder is empty and so when i put it on the mac it doesn't run the application.
What is the best way of doing this or am i barking up the wrong tree?
It seems you want to do cross-compiling, which is theoretically possible, but may not be practical, for the reasons mentioned by Marco above.
As an alternative, you could install XCode, FreePascal, and Lazarus on a MacOX machine. You could still do your development and some testing on Windows/Linux. When you hit a certain milestone, you can copy your source code to the Mac and compile your application to test and give to the user.
Even if it were possible to easily cross-compile, there some minor differences between platforms, so (especially if it's a GUI app), you would want to test it on an actual MacOS box before giving it to the client.
I've taken the route described by Noah - and I was incredibly surprised that after about three weeks development on Windows, it took about 10 minutes to get the application running on the Mac.
My route was to install Xcode 4.3 on an old Mac Mini running snow leopard, then install Lazarus using the fink version as described here. This took a while but was done in an evening.
Then I just copied my folder across to the Mac, opened the lpi on the Mac, compiled it. It failed so I removed a windows references, recompiled, and it was working. I was truly amazed.
What linker and assembler do you use to generate binaries? To my best knowledge the linker for recent OS X versions is not available in source.
Afaik what you want (crosscompiling to Mac) is not possible for recent versions (and I've done it for PowerPC myself in the past).
The easiest is to use the Unix "file" command on the binary to see what is generated, and make sure it reads something with "MachO" in it. Easiest is if you have a Linux install (where this command is pretty standard), but versions can be found for windows too (cygwin, mingw and 3rd party)
i'm developing iPhone apps. Yesterday i updated leopard to snow leopard. Alongside i made the jump from XCode 3.1.4 to 3.2.4
I was always quite happy with XCode - working most of the time under windows, I really appreciate how well the XCode toolchain works together.
however - i'm not happy with 3.2.4 at all. i experience a lot of flaws, mainly with debugging. When an error arises, the debugger often stops at another place than the actual error happened. Sometimes the debugger does not trap into breakpoints at all and i get after some time a Error from Debugger: mi_cmd_stack_list_frames: Not enough frames in stack - whatever that means. And also I get invisible breakpoints which i can't remove anymore.
Does anyone experience similar things with XCode 3.2.4? if so, which is the newest release that works well?
Thanks!
Usually the problem is to do with level of debug symbols or some compiler optimization (which shouldn't be applied in debug builds). Maybe the information here will help.
Also try a complete clean (delete the build folder, remove the app from the device/simulator) & rebuild. Ensure you're working with the Debug configuration.
I'm just starting out with GWT but I can't even run the getting started example without getting the following error:
Invalid memory access of location 0x10 eip=0x93624148
I am aware of the "java hosted mode 32 bit" stuff, anyway I tried every combination I could think of and still could not get away with that error.
I tried:
Using the eclipse plugin
Setting all possible jvm switches in eclipse to 1.5
Use the command line tool
Set the java environment to java 5 32 bit in the preference pane, and do all of the previous options again, without success (I checked that effectively "java -version" gives me the right 32 bit jvm)
Any suggestion? I can't believe that something which should be apparently immediate is so difficult ...
Thanks for your help
Best regards

Seems to be fixed in GWT 2.0.
Alternatively, try using the WebKit Nightly.
Steps here:
http://grack.com/blog/2009/11/16/fix-for-gwt-hosted-mode-crash-with-safari-4-0-4/
See release notes for latest SDK 1.7.1.
You might need to switch to Snow Leopard to get it working.
Update: GWT 2.0 is just out today. Give it a go, even thought I've not seen anything related to Leopard in the change list.
I used gwt a lot on my mac with OS X 10.5 on. It actually worked fine. Have you also set the java class version in the projects facets menu in the project preferences to java 5?
You can also provide which java to use in the launch configuration, you don't need to modify in the Mac OSX preference pane.
I actually upgraded to 10.6 when it came out, and it made life with GW easier.
Hope it helped, if you have any more questions let me know.
Best - István
