DJGPP cross compiler crashes.

DJGPP cross compiler crashes.

[Carlo B.]

Hello everyone,
I would like to signal that the DJGPP cross compiler, included into
the available packages, crashes as soon as you try to compile
something with it.
To reproduce the problem, just create a simple source file with just
this line for simplicity:

int main() { return 0; }

and after calling:

i586-pc-msdosdjgpp-gcc c.c -o c.exe

you will get:

collect2: fatal error: ld terminated with signal 11 [Segmentation
fault], core dumped
compilation terminated.

I bypassed the problem by recompiling DJGPP cross compiler myself with
this utility:

https://github.com/andrewwutw/build-djgpp

however, I'm signaling the problem in case somebody would like to fix
the trouble with a working package.

Sincerely.

Doesn't, here.  It just works.

Hello,
well, I tried both versions of CYGWIN, 32 bit and 64 bit, even on different PCs.
I also tried to install different versions, 5.4.0 and 5.3.0 of djgpp-gcc.
I used Windows 7 64bit Home Premium and Windows 7 64 bit Professional.
Always the same result.
I have no idea how you can run it without errors, please note that
i586-pc-msdosdjgpp-gcc works fine until it does not link.

Sincerely.

Please note that this quite probably means that it's not the compiler
package itself that's causing you grief, but rather djgpp-binutils.  Or
it could be the runtime base package.

So: did you run cygcheck -c on your djgpp packages?  Check if getting
them from a different cygwin mirror changes anything?

Have you tried adding options to the gcc command line to see what it's
actually doing in some more detail, like '-v' or '-Wl,-v'?

I checked on Win10 Home, originally just 64-bit.  I've had these
packages installed for years, and they haven't changed since, so there's
not really any good reason to assume they should suddenly be broken this
week.  And at least from what I'm looking at, they aren't.

Just for making extra sure, I just added DJGPP to the Cygwin-32
installation on the same machine, and again, it just worked without a hitch.
