Unfortunately this did not solve the problem using clang-7.0 with the
gcc-8.1 backend. Most probably clang is using its own linker, rather
than the mingw-64/gcc linker, and this is causing the problem. In
clang-6.0 everything works properly.
OK, maybe other here might be able to help.
Strangely enough when I use the clang -### option to see what it is
using to link my executable it shows it is using the mingw-64/gcc
linker.
Yes, unless your clang is built with different defaults, it defaults
to use the normal linker in your environment.
Yet even with the changes I made to the linker scripts, to add '. =
ALIGN(4);' before the '__rt_psrelocs_start = .;' line in each
script, I am seeing the original problem I reported as soon as I try
to debug my problem using the mingw-64 gdb debugger. So either the
linker scripts are not being used when the mingw-64/gcc linker is
being used or the problem lies in some other reason.
Just to be really clear, you did recompile your binutils ld linker
and use the newly built copy of the executable after you changed the
linker scripts right?
No, I did not do that. I had a feeling that just changing the linker
scripts was not enough. So how do I rebuild the linker so that it uses
the changes I made to the linker scripts ? I supposed I have to be in
some sort of MSYS2 environment to do this.
Yes, the mingw64/msys2 environment should be good for that; running
"./configure --prefix=/some/path; make; make install" in the
binutils-gdb root directory should give you a ld.exe in the given path.
If this ran fine you should be able to replace your normal
ld.exe/x86_64-w64-mingw32-ld.exe with it.
Where is the binutils-gdb root directory ? Is this from within in a
mingw-w64 installation which I have already installed ? Or is this some
other directory from within an MSYS2 mingw shell ? In either case what
is the actual directory I have to be in to run the "./configure
--prefix=/some/path; make; make install" in order to rebuild ld.exe ?
Sorry, I'm out of time at the moment, hopefully someone else can help you
to finish this. Or someone can provide a prebuilt ld.exe with this patch
applied.
