Anyway, I have now run your build -library-shared.bat, however i was disappointed that after possibly an hour of build, it merely finished.
Had you followed the advice I gave in the guide and even repeated here (i.e., use the parallel build), it should have taken much less time.
Misleadingly, that window closed, leaving my previous one with the error messages showing...)
I do not see what is misleading about the window with successful build closing, as described in the guide and the batch file, the window is left open only when the build fails, so the build error messages remain available.
I want to install the static build version, if that can coexist with the debug/release versions. Do I just delete the two folders you mention in cleaning the gcc builds, and run the static build batch file?
You are mixing two things here, static/shared (affected by the value of the build parameter "SHARED") and debug/release (affected by the value of the build parameter "BUILD"). They are used together, you cannot have one without other, e.g. you can have a static debug build, a shared release build, and/or any other of the four possible combinations. They do not affect each other. As described in the guide, the libraries for the debug build have an extra "d" in their name so they can coexist in the same folder with the release libraries. Also as described there, static builds are by default generated in "WXDIR/lib/gcc_lib" while the shared ones in "WXDIR/lib/gcc_dll".
You said that my guide is overly detailed for you, but as you can see, in the end you still need to know about all these supposed "details". Had you read the guide, you wouldn't have to ask and could have saved time and effort.
Anyway, I will not nag at you anymore, it seems that that I am either unable to properly explain even the most basic things or the communication between the two of us is somehow utterly broken.
Considering that doing the things described in my guide is actually the easy part and the difficult one comes with the programming itself, I can only wish you good luck.
