2020-10-25 Sunday - GNU Compiler Collection (GCC) 10.2

 

For one who seeks to be a master of their craft - you must continually attend to sharpening the saw.

Today: A deep dive back into C++ POSIX threaded programming, using the G++ compiler, available with the GNU Compiler Collection (GCC 10.2) - and exploring the differences in C++17, and the experimental implementation of some C++20 features.

Eclipse: C/C++ Development Toolkit (CDT) Resources

Although I usually rely on Microsoft Visual Studio (or Visual Studio Code) as my primary IDEs - I'm forcing myself to use Eclipse ("2020-09" CDT release) - so that I maintain familiarity & proficiency:

• https://www.eclipse.org/cdt/
• https://www.eclipse.org/cdt/documentation.php  
• "The C/C++ Development Toolkit (CDT) is a collection of Eclipse-based features that provides the capability to create, edit, navigate, build, and debug projects that use C and/or C++ as a programming language."
• "The CDT does not include the necessary compilers and debuggers to convert C/C++ code into executable programs and to debug those programs, but it does provide the frameworks that allow such tools to be integrated in a consistent fashion. This allows you to mix and match such tools depending on your project requirements."

•  ...which leads to suggesting:
  

Cygwin

• https://cygwin.com/
• Once you have the GCC G++ elements installed, run "g++ -v" at the command line, and you should get something like this:
  

Using built-in specs.

Or, alternatively, you may wish to try LLVM

LLVM & Clang

"The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. The name "LLVM" itself is not an acronym; it is the full name of the project."

"LLVM began as a research project at the University of Illinois, with the goal of providing a modern, SSA-based compilation strategy capable of supporting both static and dynamic compilation of arbitrary programming languages. Since then, LLVM has grown to be an umbrella project consisting of a number of subprojects, many of which are being used in production by a wide variety of commercial and open source projects as well as being widely used in academic research. Code in the LLVM project is licensed under the "Apache 2.0 License with LLVM exceptions" "

• http://llvm.org/ 
  

• http://clang.llvm.org/docs/UsersManual.html#cxx
  

• "clang fully implements all of standard C++98 except for exported templates (which were removed in C++11), all of standard C++11, C++14, and C++17, and most of C++20."

• https://clang.llvm.org/cxx_status.html

Suggested Books:

• A Tour of C++ (C++ In-Depth Series) 2nd Edition (2018), by Bjarne Stroustrup 
  
  "Coverage begins with the basics, then ranges widely through more advanced topics, including many that are new in C++17, such as move semantics, uniform initialization, lambda expressions, improved containers, random numbers, and concurrency. The tour even covers some extensions being made for C++20, such as concepts and modules, and ends with a discussion of the design and evolution of C++."

2019-04-20 Saturday - Eclipse IDE v4.11 Release 2019-03 JSON Schema Validation Issues

During some recent testing of the latest release of the Eclipse IDE, v4.11, Release 2019-03 - I discovered some issues with JSON Schema Validation:

First:

While looking for a better JSON editor - I installed this plugin:

• Eclipse JSON Editor Plugin 
• https://marketplace.eclipse.org/content/json-editor-plugin 

But, I observed that

• It appears that when this plugin is installed - JSON Schema Validation (i.e. after registering the file pattern and schema URL via Window > Preferences > JSON > JSON Catalog) no longer works.

• I repeated this test several times, by uninstalling the plugin - confirming that Schema Validation worked - and then re-installing the plugin and confirming that Schema Validation no longer worked.

• I did not see any errors being logged to the Eclipse log file.

• Tested with Java JDK 12, on a Windows 10 laptop

 Issue #26 Submitted

• "Blocks JSON Schema Validation in Eclipse v4.11 (release 2019-03)"

• https://github.com/boothen/Json-Eclipse-Plugin/issues/26\

Second:

While experimenting with the JSON Schema Validation capabilities of the latest Eclipse release (v4.11, 2019-03) - I noted an error in the log (see my stackoverflow submission) - even though validation appeared to be working.

• relequestual replied soon after: "JSON Schema core dev here. Yeah this looks fine in terms of JSON Schema. No idea why an error is being throw" 

 Issue #546541 Submitted:

• "UnsupportedOperationException: Not a string: {"type":"string","format":"uri-reference"} thrown by JsonValue.java"
• https://bugs.eclipse.org/bugs/show_bug.cgi?id=546541
• (see my follow-up bug comments for additional information I found)

Subsequently:

• By changing the @schema string value from
•  "$schema": "http://json-schema.org/draft-07/schema#", 

• To:
•  "$schema": "http://json-schema.org/draft-04/schema#",

• It appears that the exception is no longer thrown. 

• However, when I change the string to either of the following: 
•  "$schema": "http://json-schema.org/draft-05/schema#",

• or
• "$schema": "http://json-schema.org/draft-06/schema#",

• ....a different error messages shows in the log - with a different exception is thrown.

2016-05-25 Wednesday - Fixing my GDB (and Eclipse CDT Debugging capability)

I previously had my Windows 10 development machine configured to successfully develop and debug C++ programs from within Mars Eclipse - leveraging CDT and Cygwin.

I recently made some changes to my system configuration - and broke my Cygwin GDB debugging functionality.

After spending a few hours exploring the problem, I thought sharing this post might help someone else minimize their cycle time if they have a similar problem...

The first clue was in a Windows Command Prompt, I got the following error when trying to launch GDB:

"ImportError: No module named site"

Also, in Eclipse, when attempting to launch the debugger for a C++ program, I encountered this error message:

 "Could not determine DGB version using command gdb --version"

I  read several forum postings - and these were the relevant takeaways:

• http://stackoverflow.com/questions/5599872/python-windows-importerror-no-module-named-site
• https://docs.python.org/2/using/windows.html
• https://docs.python.org/3/using/windows.html
• "The PYTHONPATH variable is used by all versions of Python 2 and Python 3, so you should not permanently configure this variable unless it only includes code that is compatible with all of your installed Python versions."
• "he Python launcher for Windows is a utility which aids in locating and executing of different Python versions"
• "System-wide installations of Python 3.3 and later will put the launcher on your PATH. The launcher is compatible with all available versions of Python," 

Now, in my environment, I had setup Python 2.7.11 and Python 3.5.1 - and since GDB relies on Python 2.7 - I thought, "ah, perhaps one of my library installs / updates has resulted in a broken dependency situation". So, I uninstalled and re-installed them both. 

No joy.

I then uninstalled and re-installed Cygwin.

No joy.

Then I tried alternating where PYTHONHOME and PYTHONPATH pointed...to 2.7 vs 3.5

No joy.

Finally, I removed the System Variables for PYTHONHOME and PYTHONPATH.

Success. 

When in the Cygwin bash shell (or Windows Command Prompt window) - the Windows System Variables for PYTHONHOME and PYTHONPATH were conflicting with the Python 2.7 version that is bundled with Cygwin - and a dependency for GDB.

So I then just added the dir for Python 3.5 directly to the PATH environment variable. 

Problem solved.

2016-03-04 Friday - GCC, The GNU Compiler Collection

2.0 Eclipse CDT

At the time of this writing, CDT 8.8.1 was the latest available.

You can install the CDT version of Eclipse by downloading from here:

• https://eclipse.org/cdt/

 
If you have an existing Eclipse environment already setup, and you just want to add the CDT plugins - you can add this p2 software repository link via the Help > Install New Software menu option

• http://download.eclipse.org/tools/cdt/releases/8.8.1

If you will be using Cygwin GCC compilers, then you'll probably want to make it your default:

You'll eventually need to debug something, so check to see that you have the correct debugger installed and configured properly for CDT:

Doug Schaefer is co-head of the Ecllipse CDT project - and has a few blog posts that may be of interests to CDT users

4.0 Success! Code Compiled (...and ran)

5.0 Debugging

You'll need to setup a Debug profile for your program, and specify the executable - and source file

 Set your breakpoints, and begin a debugging session...

6.0 Additional References

If you run into an issue such as "Symbol 'cout' could not be resolved", or "Symbol 'std' could not be resolved" - you may need to manually add the appropriate Cygwin include directories, select the correct toolchain entry, and try closing and opening the project.

2014-11-28 Friday - Dev Lab Upgrades

Although my role these days is primarily as an architect - I continue to keep my hands firmly familiar with the full technology stack of tooling for developing solutions on different platforms.  A core belief in my view is that architects must not lose touch with their coding skills...and even better, when they are active contributors within an organization...

This post will be a bit messy over the next few days as I continue to add links, commentary, and clean-up the list with the final bits of software upgrades and installations.

My current primary dev machine is a Sony Viao VPC-F23BFX/B notebook running Windows 7 64 bit, with 8GB of RAM, with an Intel Core i7-2670QM processor (quad core, 8 threads, 2.20 GHz), a 640 GB internal hard drive, an NVIDIA Geforce GT 540M GPU, dual external LG Flatron E2260 LED-backlit LCD monitors, and two external USB attached Western Digital My Book drives (an older  2x500MB drive configured with RAID 1, and a more recent 2 TB drive). Additionally, I leverage various cloud hosting service providers when additional hardware/server test configurations are needed.

I've kept several older versions of Eclipse handy as part of my personal Dev Lab environment - but this week decided to discard them and work exclusively in the 4.4 (Luna) release.

Additionally, there are a number of tools which I've spent some time upgrading to their latest releases:


Virtual Machines...
- Oracle VM VirtualBox 4.3.20

If you have used Subclipse in a previous version of Eclipse - and then think, "oh, why don't I try Subversive this time?" (or vice versa)  - then you'll probably find these links helpful (eventually)...

2011-02-26 Saturday - Aptana Pydev "no such file to load"

I've discovered an issue with the latest release of the Aptana Pydev plugin for Eclipse (Aptana Pydev 1.6.5.2011022501).

An internal error occurred during: "Loading bundle: C:\eclipse\configuration\org.eclipse.osgi\bundles\1026\1.cp\bundles\bundle-development.ruble".
(LoadError) no such file to load -- ruble/ui

Also tote: I'm running Eclipse Helios 3.6.2.r362_v201102120-9gF78Gs1FrIGnHDHWkEcopoN8AmxeZflGDGKQi
Build id: M20110210-1200

I posted a message to this thread:

and also found a similar sounding previously reported problem here:

2009-02-07 Saturday - Eclipse Financial Platform

A new Eclipse project has been proposed: Financial Platform.

Given my previous experience leading the design and development of commercial software in the banking and financial services sector, I am intrigued by their vision / goals.
