I've just installed mono complete, mono-vb and associated libraries, it all appears to be there.
I've written the simplest of vb examples:
print "Hello, this is a test"
end
but vbnc gives me an error "Expected identifier" for each line. I've tested with more lines of code and I get an error for each line in my file.
What am I missing?

I'm studying the online course from nand2tetris.com through Coursera. When I try to run the nand2tetris CPUEmulator I get the error message 'Illegal character'. Even the simplest program with one command '#0' I get the error message. I tried indenting 0-10 spaces, and I tried the binary version of the command '0000000000000000' and I still get the error message. To run the emulator I'm using a MacBook and I type the command 'CPUEmulator.sh' into the terminal. I'm using TextEdit with Plain Text format. I named the file 'test.hack'. What am I doing wrong?
I use my own interpreter to run the lua program and debug with zerobrane. If the interpreter encounters an error, how to let the debugger break at the error line?
There is no mechanism in Lua that allows to catch run-time errors. There was a call to debug.traceback function in Lua 5.1, but it's no longer called in Lua 5.2+. If you have your own error handling, you can call require("mobdebug").pause(), which will request ZeroBrane Studio debugger to stop on the next executable Lua line, which will allow you at least to see the stack trace and the location of the error, but this is probably all you can do. You can also try to assign debug.traceback to the function that calls pause, but, again, this will only work in Lua 5.1.
For example, try running the following script from the IDE:
require("mobdebug").start()
debug.traceback = function(...)
print("traceback", ...)
require("mobdebug").pause()
end
a()
print("done") -- it will never get here
If you save it into on-error.lua file and run, you should see the execution stopped on line 5 (after the pause()) call with the following message:
traceback on-error.lua:6: attempt to call global 'a' (a nil value) 2
I have the following line in a CMakeLists.txt file...
else
message(FATAL_ERROR "Could not locate Lua 5.1.\n"
"Please download from Lua website.")
endif
When I run cmake, I get the following error...
Parse error. Expected "(", got newline with text "
".
Okay, I figure. That isn't valid syntax, so I'll just edit the cmake file to put it all on a line like so...
message(FATAL_ERROR "Could not locate Lua 5.1.\nPlease download from Lua website.")
Go to the directory where I ran cmake, delete all the cache stuff, re-run it, and I get the same error as before. I've even deleted that whole line and I keep getting the same error. I'm obviously missing something crucial that defines how cmake operates, but I'm not sure what.
Any help is appreciated.
The if, else, elseif, and endif all need () after them.
I'm trying to use Doxygen with Xcode. I followed the Apple tutorial. After several mistakes, I builded the project and generated the docs. I discovered that if you save the doxygen.config from Doxygen and you use space " " in the directory name you will have problem and others things.
But there is one last problem:

Failed to create docset indexer object
make: *** [docset] Error 1

I don't know what is the problem?? Any idea?
I'm using Core Data - sqlite.
The parser is telling you XML is not well formed, but that error usually shows because nothing has been generated BEFORE running docsetutil.
First thing should be to go over the many lines of console output and look for warnings, probably is there. Also look for the docset you generated and right click > Show Contents. If you don't see a lot of html files with the documentation, same thing: you failed at generating documentation and docsetutil has nothing to do. And btw, it's docsetutil who is using CoreData, doesn't matter if you use it on your project or not.
I don't get why Apple doesn't provide a doxygen-like tool more tightly integrated. Or a better code formatter than Crustify. Just take the damn tools and improve them a little bit. Argh!
There is a know bug from generation of Nodes.xml by Doxygen. It is referenced here https://bugzilla.gnome.org/show_bug.cgi?id=671591 and should be corrected in the next doxygen Version (Post V 1.8.0) :
At the end of the Nodes.xml there is an additional
the -silence option is workaround to suppress error, but this param does not allow dosetgeneration to work properly.
$DOXYGEN_PATH $TEMP_DIR/doxygen.config
make -C $TEMP_DIR/DoxygenDocs.docset/html install
Insert following code
Note : The script works in $TEMP_DIR and not in SOURCE_ROOT as AppleScript
$DOXYGEN_PATH $TEMP_DIR/doxygen.config
# make will invoke docsetutil. Take a look at the Makefile to see how this is done.
LINE=`xmllint --c14n $TEMP_DIR/DoxygenDocs.docset/html/Nodes.xml 2>&1 | awk 'NR == 1 {print $1}' | cut -d':' -f 2`
ECHO $LINE
if [ $LINE -gt 0 ]
then
echo "XML Cleaning "
sed -i.bak $LINE'd' $TEMP_DIR/DoxygenDocs.docset/html/Nodes.xml
fi
make -C $TEMP_DIR/DoxygenDocs.docset/html install
NB: awk and sed may certainly be combined in one line.
So the long story short is that the script creates a Doxyfile on the fly, and it does not recursively scan all subdirectories.
Take a look at this post:

There's a script included on the second post that is based on Apple's script that shouldn't have this issue.
I use an extended version of the above script but based on the same priniciples. Although everything works fine on another project this time my script fails.
The generation of the docset works fine but the make command produces the following error.

The make command I use is: make --silent -C "$DOCSET_OUTPUT/html" install.
I added line breaks to the error message for readability.
I'm trying to work through Apple's CoreData Utility Tutorial. It asks me to create a 'Foundation Tool' project in the 'Command Line Utility' section. In XCode 3.2, I only found a 'Command Line Tool' section with a 'Foundation' type in the 'New Project' wizard.
So I created the 'Command Line Tool' 'Foundation' type project, and added the following line to enable garbage collection:
objc_startCollectorThread();
I also changed the 'Objective-C Garbage Collection' setting in my 'Target Info' 'Build' tab to 'Required [-fobjc-gc-only]'. When I run my build, I get the following error:
warning: implicit declaration of function 'objc_startCollectorThread'
The target runs fine so far. All it does is print 'Hello World' to the console. I'm just concerned about this warning. I must be doing something wrong if I'm getting warnings for something as basic as garbage collection on a command line tool.
You should #include <objc/objc-auto.h>, which is where this function is defined.
