QNX Momentics IDE 8.0 (Build 2027): Release Notes

The major changes are:

• Support for QNX SDP 8.0 (including updated command-line tool support)
• Support for Java 17
• Built on Eclipse Platform 4.28 and CDT 11.2 (Eclipse SimRel 2023-06)
• Compliant to the C11, C17, C++17 and C++20 standards (IDE editor)
• Third-party plugins have been updated to fix any known security issues

Mac support:

Support for macOS has been removed.

Some Memory Analysis features are removed:

The lib allocator is replaced with ptmalloc. The supporting library librcheck has been re-written to accommodate this. Accordingly, the Bins, Bands, and Usage tabs are removed from the Memory Analysis editor.

Changes to system information allocator tab:

In the Malloc Information view of the System Information perspective, Total Heap is renamed to Total Allocator Managed Memory. Memory distribution is no longer available. All charts except Overview History are removed. The stats for realloc are not available; only corealloc and corefree are available.

Formatting of event changes:

The System Profiler has been adapted to support event formatting for QNX OS 8.0.

The memory values for Data, Code, and Stack are reconciled with pidin and multiple System Information panels:

The System Resources view has been updated. The Data and Code columns are now totals for the process. Separate columns called Program Data and Program Code have been added.

System Profiler Interrupt Summary:

When opening a trace in the System Profiler, in the System Activity Summary, the entry for interrupts outputs as 0. Interrupt Service Threads (ISTs) have replaced Interrupt Service Routines (ISRs) in QNX OS 8.0.

Application Profiler view C++ function names look mangled:

• When creating and building a C++ project with functions, the functions' names are mangled. (Ref 2940094)

  Solution: The function names appear correctly now.

Valgrind doesn't work out of the box:

• When launching a project with Valgrind, the required libraries cannot be found. (Ref 2914511)

  Solution:The IDE now downloads all the required binaries to the target.

In Eclipse, special keys don't work after creating a new project:

• When creating a new project, control keys like Enter, Backspace, or key combinations like Ctrl+A and Ctrl+V, don't work. (Ref 2887741)

  Solution: This is an Eclipse platform issue.

  Refer to the Eclipse bug tracker for more information.

gles2-gears does not compile in IDE:

• If you import a non-IDE project that uses managed recursive makefiles, the IDE incorrectly modifies the makefiles. The project won't compile, and you'll see errors about variables not being resolved. (Ref 1685684)
  Workaround: Modify common.mk to include .qnx_internal.mk after all variable assignments. For example:

  INSTALLDIR=$(firstword $(INSTALLDIR_$(OS)) usr/bin)
  LIBS += EGL GLESv2 screen m
  
  include $(MKFILES_ROOT)/qmacros.mk
  ifndef QNX_INTERNAL
  QNX_INTERNAL=$(PROJECT_ROOT)/.qnx_internal.mk
  endif
  include $(QNX_INTERNAL)
  
  include $(MKFILES_ROOT)/qtargets.mk

  Note:

  This issue doesn't apply to projects that use managed recursive makefiles but are created in the IDE.

Hover-help for lib functions that pass functions is truncated:

• If you try the hover-help for C library functions where the prototype includes a function as a parameter (e.g., atexit(), InterruptAttach(), pthread_create() ), the function prototype in the hover-help is truncated at the first closing bracket in the parameter list; this is the closing bracket for the function parameter, not the proper end of parameters list. (Ref 929140)

  Solution: Hover on functions works with no truncating of functions with closing brackets in their arguments.

To start the IDE:

• On Windows, choose QNX Software Systems > QNX Momentics from the Start menu, or use the desktop icon.
• On Linux, run IDE_base_dir/qde, where IDE_base_dir is where you installed the IDE package.
