If this is the wrong place for this question I apologise and please redirect me to the suitable section.
I'm somewhat rusty on installing from command line, especially on Windows. I decided to install the latest Perl version on my PC, running under Windows 10. I had previously installed it using Strawberry Perl download, but as it was a few versions out of date I decided to remove it and refresh my skills (ha) by installing it manually. I downloaded the lastest Perl release from https://www.perl.org/get.html#win32 and have been reading the README.win32 to make sure I install it correctly.
As I need a compiler, I decided to use Gcc and dmake. I installed and can run them successfully so went back to installing Perl. As per instructions I tried running dmake in the win32 subdirectory in the Perl download folder. Before this I edited makefile.mk, where these variables are uncommented from the Build configuration section:
INST_DRV/INST_TOP (left as is)
INST_VER *= \5.26.0
USE_MULTI *= define
USE_ITHREADS *= define
USE_IMP_SYS *= define
USE_LARGE_FILES *= define
USE_64_BIT_INT *= define
USE_LONG_DOUBLE *= define
DEFAULT_INC_EXCLUDES_DOT *= define
CCTYPE = GCC
GCCWRAPV *=define
CCHOME *= C:\MinGW
(nothing else changed after this)
When I run dmake in the directory, it quickly comes to this error:
gcc -c -I.\include -I. -I.. -DWIN32 -DPERLDLL -DPERL_CORE -s -O2 -

I get a bunch of warnings beforehand about casting from pointers to integers of different sizes, but this is the bit where it stops and produces an error. Am I missing something obvious? I haven't done this for a while, so I'm hoping it is a silly user error on my part! Thanks.
Try obtaining the MinGW source packages, and installing using makepkg-mingw to build them.
Most if not all have patches applied to customize (or fix) them for the MSYS2/MinGW environment.
Stock source downloaded from its author may not compile directly in that environment the way it would on Linux, or OS X using "configure" and "make".
Instructions are available, and there may be other similar instructions out there associated with Arch Linux.
