Hello,
I’ve been evaluating VisualGDB for use in our company. There have been a few issues that cropped up right away, so I’d like to collect them in this topic.
Additional context: This is a
CMakePresets.json-based CMake project.- Clang IntelliSense can’t find headers when no toolchain is configured for the project.
- Our Gdbserver rejects the port argument when it is given as
:2000. It wants something like123.123.123.123:2000. - Deployed files cannot be checked for whether they are up-to-date with
stat. Our target system doesn’t have that command. - Building only a specific target fails. The command line looks like
cmake.exe --build --target HelloWorld build/debug-linux-arm-gnu. I believe the folder should be after the--build. - Upload fails. On the first try, the file simply doesn’t exist where it was supposedly uploaded to. On subsequent tries, I receive access violation errors from VisualGDB or Visual Studio crashes, which isn’t surprising given the access violation error.
To 1.:
We already define our toolchain via a toolchain file that is also pulled in via the presets file. We really do not want to make our developers configure the toolchains globally as they are checked into VCS and each project might pull in different versions of toolchains. It must be possible to retrieve this information another way to make IntelliSense work.
To 3. and 5.:

Our system is very slow at processing encrypted data and that can cause uploads of ~100 MiB, which is a typical size for our binaries, to take several minutes.
By the way, the upload test procedure always pretends to succeed, but the file still isn’t uploaded.
