wlink memory could not be read error

[Pokeman2003]

I tried to compile this source code I've been experimenting with using a pretty standard IDE directory, but Resource/M_Main.rc, by all accounts a very standard resource script, causes WRC to crash with a "this memory could not be read" error. For what it's worth, the path that I put this folder in(...\Documents\Projects\Win32 Experiment\Source) has exactly one space, which may be resulting in the crash.

Okay, I somehow misidentified the program that was crashing. None the less, wlink is still crashing, and it looks like the resource files might be involved because removing the RC files from the IDE will cause it to successfully link.

What a trainwreck, I am so sorry for screwing up my original issue. This is the current IDE directory as it stands right now.

I am sorry, but from the messages you can see that your project has redefinition of many symbols. I don't see any issue with wrc. It looks like mismatch in your project. As you see messages, wlink select one of symbol version, each can have different parameters etc. You need to check and fix it first.

Anyway I need fully compilable sample including IDE project definition. The only sources is useless.

[Pokeman2003]

Full Directory.zip Okay. This should be everything. I don't know what else you need.

I don't know what's causing the redefinition errors at all. For example: executionHandle only shows up in Win32.h, and yet Classes.c is complaining that I've somehow redefined it. It gets it from Windows/Windows.h. Not a single one of its other header files(Messages.h, Window/Classes.h, and Resource/Resources.h) includes Win32.h, it's only Windows/Windows.h. executionHandle isn't even USED in Classes.c, there should be no chance of redefinitions in the slightest.

[jmalak]

The duplicity is due to you use definition in header file instead of declaration.

You must define it in single object and in header file must be only declaration. By example for executionHandle in Win32.h you define it by HINSTANCE executionHandle;

but there should be declaration only as extern HINSTANCE executionHandle;

and definition only in one C source file by example in Entry.c HINSTANCE executionHandle;

Cool, well that quirk is now fixed. Weird way of approaching that. I don't recall any other compilers that required me to do this, but then again I haven't coded in C for years at this point and I didn't get far last time.

If anyone wants the updated package, here you go. It'll reduce those warnings to dust... buuut I'm still suffering the same issue illegal instruction error. However, it looks like it's wlink now? It's Error #2.log now. Full Directory 2.zip

Edit: oh no

[jmalak]

Anyway it looks like as bug in wlink if multiple resource files are used and some of them are blank as in your test case. Normaly this issue is not happen because in real case you add non-blank resource file only. I will fix it.

To declaration/definition issue. It cannot be reported by C compiler because it is valid code. It is logical mistake which is reported by linker and it depends on what each linker report as error or warning etc.

[jmalak]

Anyway your IDE project is correct (relative paths) because I used it on my box on different path without problem.

[jmalak]

It should be fixed now. Download new build after build finish.

[Pokeman2003]

Due to circumstances outside of my control, I couldn't download the build last night when you requested me to do the test. The most recent build, 2024-10-11, is spitting out the error "can not connect to batcher spawn server". I'm going to look into trying to compile your commit myself.

[Pokeman2003]

The commit solved it, sweet!

For the record, the installer should probably get updated at some point to request closing EVERY executable found in the bin* folders before trying to selectively install or delete things. Turns out, my issue wasn't that the build was bad, it was that there were some leftover batchserv instances in the binnt folder.
