BUGGED selection of MinGW-w64 toolchain

[b.timofte]

HI all

I am trying to use Mathworks MinGW-w64  compiler

“C:\ProgramData\MATLAB\SupportPackages\R2018a\3P.instrset\mingw_w64.instrset\bin>gcc -v

I selected in the project add new toolchanin by Locating it and it detected it ok

 

When i try to build the project i get this error :

It was already imported at “C:\Users\xxx\Desktop\Study\MATLAB\Matlab_To_C\SFunction\Simple_Function\SFunction\SFunction\SFunction.vcxproj (41,5)”. This is most likely a build authoring error.

Hi,

It looks like Visual Studio might have cached the old toolchain list. Please try restarting it.

Ok Worked .

 

Another issue is when i attach to Matlab.exe it takes 20 minutes to load all dlls. Is this a bug in gdb.exe?

This is how part of the log looks …. It goes on for 20 minutes on a core i7 2.8 Ghz … Wtf 🙁

Hi,

The best way to diagnose this would be to narrow it down to a specific component. Please try attaching to the target process by running gdb directly from command line. Do you observe the same behavior?

If not, please enable the GDB command timing view in the GDB Session window and check if the delay comes after any specific command (you can also enable the creation of detailed gdb logs via Advanced GDB Settings – the created logs will contain timestamps for every line).
