Odd GCC linker errors
« on: September 13, 2022, 09:15:04 AM »
GCC seems to be always failing now when attempting to link OS4 object files together. No errors/warnings are produced during compilation, but it appears to be producing malformed object files because linking is giving nonsensical error messages such as:

mce.o: In function `no symbol':

etc. I did not use most of these identifiers even once let alone multiple times. These kind of errors are produced no matter which program I am trying to link, even programs that used to build fine. I did not make any changes to makefiles or other settings. I thought GCC may have become corrupted so reinstalled the SDK, but the problem persists.

I've encountered such errors when the makefile was corrupt and missed the "-c" option to produce object files.
Check if the object files were really created - I'm in doubt of that.

That doesn't seem to be the issue, the object files are being generated and the -c flag is present.

Have you tried to compile one of the examples/gui sources, without using any makefile? Does it produce the same errors?

I've now identified the bug; it is the WinUAE filesystem emulation. If the source files are in a host Windows (NTFS) directory, it fails. If instead a HDF is used, it succeeds. I will add a note to the Amiga Coding Guide ( http://amigan.1emu.net/releases/ami-code.txt ) about the issue. Thanks to Joloo and walkero for your help.

I am glad it was resolved and is working fine for you now. I didn't do much of help.
You got some quite useful stuff on that page. I will keep it in mind. Thank you for sharing it.

I've now identified the bug; it is the WinUAE filesystem emulation. If the source files are in a host Windows (NTFS) directory, it fails. If instead a HDF is used, it succeeds.

I can't reproduce it using MS Windows 8.1, WinUAE 4.9.1.0, AmigaOS3.0 up to and including AmigaOS3.9 and either gcc 3.3.0 or gcc 3.4.0.
But as you wrote, you run AmigaOS4 inside WinUAE - so a difference to my test environments. WinUAE is also running as a privileged process here - which could make a difference, but I'm not sure. I'll have to dig a little deeper, but not today.

Nonetheless, I'm glad you figured it out.

I will add a note to the Amiga Coding Guide ( http://amigan.1emu.net/releases/ami-code.txt ) about the issue.

I'll look at it - but there is too much information for me to read at the moment.
So much information, so little time... :-(
Known problem? ;-)

I have now done several tests in order to find out whether the bug you describe is caused by WinUAE or by the host operating system (Windows 8.x, 10).
It is not related to MS-Windows and the used file system (NTFS, FATxxx) - here all tests, regardless if WinUAE was fired up with administrative privileges or not, did not cause any issues (under AmigaOS3.x).
My best guess is that the issue is solely related to AmigaOS4.x, as I can't imagine that QEMU is the cause and no one ever spotted this strange behaviour before.

It would be interesting to know if other Linux tools that store binary data in big-endian format also suffer from this.


Kind regards.
