Turning on the /analyze flag to run PREFast for Windows builds using MSVC non deterministically throws the below error. I think this is because ninja is trying to optimize builds by compiling files from the same target simultaneously but since each target logs to a single file, MSVC is not able to edit the file while another process is writing to the same log file because the file the other process is compiling belongs to the same target.
fatal error C1258: Failed to save XML Log file '<path to log file>.xml'. The process cannot access the file because it is being used by another process.
Can I write to different files per target ?
Can I make MSVC smarter and force it to attempt to write despte another process writing to it ?
I don't want to set paralell jobs to 1 , so do I have any other options ?

I am trying to create custom snapshot from some Javascript file. I was able to create a snapshot using the command
mksnapshot.exe snapshot11.js --startup_blob snap.bin
but when I was trying to create an Isolate with this snap.bin file I got this message
The Isolate is incompatible with the embedded blob. This is usually caused by incorrect usage of mksnapshot. When generating custom snapshots, embedders must ensure they pass the same flags as during the V8 build process (e.g.: --turbo-instruction-scheduling).
I am guessing that I need recreate the snapshot with the proper flags but I couldn't find which flags I need to use.
My args.gn
is_component_build=true
v8_static_library=false
is_official_build=false
is_debug=true
use_custom_libcxx=false
use_custom_libcxx_for_host=false
target_cpu="x64"
use_goma=false
v8_use_external_startup_data=false
v8_enable_i18n_support = false
symbol_level=2
v8_enable_fast_mksnapshot=true
Any lead will be helpful.

You can invoke ninja with -v to have it print all the commands it executes; e.g. if you compile V8 with:
ninja -v -C out/... v8_monolith
then you'll find a line for the mksnapshot invocation in the output, and can copy the flags from there. (If you have already compiled V8, ninja will say "nothing to do"; in that case you can either clean out everything, or just delete snapshot_blob.bin and libv8_monolith.so.)
I have successfully built OpenDDS 3.13.2 from source. Here is my environment:
Windows 10
Visual Studio 2017 (re-targeted Solution to SDK 10.0.17763.0)
Tried all Configuration/Platform combinations
I successfully used the configure script from the VS command prompt, built everything by opening the generated solution in the same command prompt, and finally ran the Messenger example (publisher and subscriber), and even configured it to use RTPS successfully.
However, when I try to create my own IDL and use the tao_idl, it crashes. Here's my test (using the proper environment from setenv.cmd):
> tao_idl (no args)
IDL: No input files
Second test:
> tao_idl Test.idl (crashes)
I get no error message, and am unable to locate logs or any indication of what went wrong. The same thing happens when I used opendds_idl.
What is the best approach to debug this, and/or are there pre-built binaries available for the IDL compiler(s) (both TAO and OpenDDS)?
After about a day of troubleshooting, I have determined a solution. Despite being able to call tao_idl and opendds_idl yourself, you should basically never do it. There are a good amount of command-line arguments needed to get both to work, and if they're not present, each exe will crash without the proper reasoning why.
I will add my steps below to create a new basic two-exe pub/sub project using OpenDDS:
Create your own IDL file.
Starting with the DCPS Messenger example, modify the .mpc file, replacing Messenger.idl with your IDL file name.
Create a new file called <your project>.mwc, and add the following contents:
workspace {
// the -relative and -include cmdlines make it so this workspace
// does not have to be in the $DDS_ROOT directory tree.
// tell MPC to substitute our DDS_ROOT environment variables for relative paths
cmdline += -relative DDS_ROOT=$DDS_ROOT
// tell the projects where to find the DDS base projects (*.mpb)
cmdline += -include $DDS_ROOT/MPC/config
}
Open a new VS command-line terminal and run $DDS_ROOT/setenv.cmd, or open a regular terminal if you have those environment variables set via Windows settings.
Navigate to your project directory and call: mwc.pl -type vs2017, replacing "vs2017" as needed for your build tool/IDE.
Open up the generated solution, and retarget it as necessary for your Windows SDK version.
Build the <your project>_IDL project first. If you notice in the output window, it is invoking the tao_idl and opendds_idl commands automatically. You can view the .vcxproj files to see the full command-line arguments that were the original problem.
Modify the publisher.cpp, subscriber.cpp, and DataReaderListenerImpl.cpp files to match your new IDL. Run the example as usual and ta-da!
For completeness, the full commands for both tao_idl and opendds_idl are as follows:
> opendds_idl -Sa -St "<your file>.idl"
> tao_idl -Wb,pre_include=ace/pre.h -Wb,post_include=ace/post.h -I$(TAO_ROOT) -Sa -St -I$(DDS_ROOT) "<your file>.idl"
> tao_idl -Wb,pre_include=ace/pre.h -Wb,post_include=ace/post.h -I$(TAO_ROOT) -Sa -St -I$(DDS_ROOT) "<your file>TypeSupport.idl"
I am using QtCreator 4.1rc1 under Windows with the msvc tool chain. The debugger is cdb from the Windows 8.1 SDK. I had the same issue with older versions of QtCreator.
When I debug my application, then there are many messages to the output (and issues) pane in the form
Exception at 0x773596c2, code: 0xe06d7363: C++ exception, flags=0x1 (execution cannot be continued) (first chance) in WinSCard!SCardTransmit
I understand, that this is to be expected under Windows and those exceptions are actually not a problem. But they pollute the output and issues pane and basically render them useless.
So I tried to get rid of the messages. But failed after hours trying. What I tried is the following:
Use the check box 'Ignore first chance access violation' under Tools->Options->Debugger->CDB
Specifying command line arguments to cdb.exe: -xi
Create a script file for cdb.exe to be used at startup to avoid the warnings. The script contained the commands 'SXI 8010000a; SXI 0000071a; SXI e06d7363'. I tried placing the script in several directories and also specifying it with the command line options -cf or -cfr.
When I run cdb.exe from a command line using the startup script, it works! No exceptions are printed to the console. But when I start it from QtCreator, they are there again.
I assume, that QtCreator is using their own startup scripts and those overwrite the ones I specified.
Has anyone succeeded in hiding those exception outputs under QtCreator with cdb?
I am creating setup of large data approximetly 10 GB with NSIS Script and trying to create a single setup (exe). Its giving an Error -
Internal compiler error #12345: error mmapping file (xxxxxxxxxx, xxxxxxxx) is out of range.
Note: you may have one or two (large) stale temporary file(s) left in your temporary directory (Generally this only happens on Windows 9x).
Please tell me how to solve this issue ?
Is there any other way to create a setup for this kinda situation ?
NSIS installers are limited to 2Gb.
If you absolutely need it to be one file and you want to continue to use NSIS you have to append the data to the end of the generated setup. I'm not sure I would recommend that approach but it could work if the appended data is a zip file (or some other format with the header at the end) and you use one of the NSIS zip plugins to extract at run-time...
I have used https://sourceforge.net/projects/nsisbi/ instead of normal NSIS. It solved the problem.
I was using Silent Install Builder 5 and received this same error with a package installer that had LESS that 2 GB total. Once I determined that the NSIS compiler was to blame, I began experimenting with several possible solutions and here's what worked: I downloaded the newer NSISBI compiler from here https://sourceforge.net/projects/nsisbi/ and then did these 3 steps:
Go to C:\Program Files (x86)\Silent Install Builder 5 and renamed the default NSIS folder to a new name.
Copied the NSISBI folder into the C:\Program Files (x86)\Silent Install Builder 5 directory and renamed IT to NSIS.
Tries to compile some large packages above and just below 2GB and the first few tries I would get missing file errors in the Silent Install Builder 5 compiling box. No worries because the missing files are in the old NSIS folder, that's why y9u don't delete it.
Each time find the missing file error displays, find the missing files and copy them into the same folder location in the new NSIS folder. About 3 times you will do this until there are no more errors at all and you can then include the large files without generating the "internal compiler error #12345: error mmapping file xxxx is out of range." error message. NSISBI works!
I am trying to run a program that does not include any opencv files, but for some reason this error keeps popping up and preventing me from running the program.
LNK1104: cannot open file 'opencv_core246d.lib' C:\Users\Public\Documents\imgSwitchingFiles
Please can somebody shed light on this issue?
It looks like your project options state this library should be linked to your binaries. Did you reuse this project from elsewhere?
If you really don't need OpenCV, simply remove its libraries from the project linking options.
In project properties:
VC++ Directories>Library files>C:\OpenCV2.4.3\build\x86\vc9\lib
&
Linker>Input>Additional Dependencies>
Add the following under edit (each on a new line)
opencv_core243d.lib; opencv_imgproc243d.lib; opencv_highgui243d.lib; opencv_ml243d.lib; opencv_video243d.lib; opencv_features2d243d.lib; opencv_calib3d243d.lib; opencv_objdetect243d.lib; opencv_contrib243d.lib; opencv_legacy243d.lib; opencv_flann243d.lib;
Your file paths may be different i.e. vc10 instead of vc9 or u may have x64 instead of x86.
Also u will have 246 in every .lib instead of 243.
