Hello there,

if anyone's still listening on here... (site seems to be down since today?)

wanted to play a bit with DOSBox and DIY programs to run on it.

I went to the DJGPP site and used the file picker to give me the list of
needed files for compiling on a windows host, with Allegro.
(Although I did not link Allegro at this point.)

Unzipped everything into a folder:
C:\DJGPP_GCC9
and set up env variables for DJGPP to the .env file and DJDIR to this dir.

(the gcc9 appendix because I also tried some guy from the internet's
gcc4.2.1 with allegro all-in-one package, and I did get stuff compiled
with it, but when I saw there's actually a GCC9 version, I needed to try
that)

I literally made a helloworld program:

#include <stdio.h>
int main(const int argc, const char** argv)
{
     printf( "Hello World!" );
}

Saved in: C:\DOSBOX_dos_projects\DJGPP\testproj\test.cpp
With Windows7 (32bit) Cmd shell in that folder, called this, and got the
output:

C:\DOSBOX~3\DJGPP\testproj>gcc -g test.cpp -o test.exe
Exiting due to signal SIGSEGV

.
Since the delorie.com site is currently down I looked elsewhere and
found some FAQ where it says this could come from the .env file having
extra whitespace somewhere... although supposedly fixed by now. And I
did not edit that file, it's the one I just unzipped.

Any ideas what could be wrong?
