Did something change wrt swapstack.o?

[mheyer32]

DOpus is not linking anymore, complaining about a missing swapstack.o:

And indeed, I can't find swapstack.o anywhere in the output directory...

Weird, I did a make update today, now compiling DOpus ends up in:

caused by a bogus fix for https://github.com/bebbo/gcc/issues/233 ... test in 30 mins

-stackswap

Please update your own spec file and use -u___stkswap since that file is in the library now. Or don't use an own spec and define the reference in the code:

  unsigned long __stack = 42000;
  extern long __stkswap;
  long * __ref = &__stkswap;

[mheyer32]

Thank you! The compilation error got fixed. Removing the referal to the .spec file and -stackswap and replacing it with -u___stkswap let it compile again. But now the program crashes at startup - could be some other failure.

You can try your own build: checkout https://github.com/mheyer32/dopus5allamigas/tree/new_stackswap

go to /source and build: make os3 release debug=<yes|no>

Then the whole build ends up as a zip file under /release

[bebbo]

if you want to pass -u___stkswap to gcc (and not to the linker directly), then you have to use -Wl,-u___stkswap

[mheyer32]

So, I was able to track down the crash at DOpus' startup to opening sysinfo.library. It is unclear to me why that is, but I don't think its compiler related. Renaming sysinfo.library gets DOpus to start properly.

Is there a way to confirm that the -Wl,-u___stackswap mechanics are working properly?

[bebbo]

grep stkswap bin.os3/DirectoryOpus_unstripped

This is wrong. use -Wl,-u___stkswap

[mheyer32]

Oh, ok, it's typo in my comment. I think I copy&pasted correctly:

https://github.com/mheyer32/dopus5allamigas/commit/ae80ab910defbf63a6d345ff03eb8ea0595b8655

[bebbo]

so what is the grep command printing?

[mheyer32]

Looks good!(?)

➜  source git:(master) ✗ grep stkswap bin.os3/DirectoryOpus_unstripped
grep: bin.os3/DirectoryOpus_unstripped: binary file matches

[bebbo]

And if you are curious you might test -Wl,-u___checkstack too. Use both together.
