Hi Viktor,
To be concluded from your ranks is that POCC is indeed more intersting than
BCC; is POCC the same as Pelles ISO C Compiler 2.70
On their website there's only a download for version 5.00.1 - am i missing sth?
best regards,
frank

Additional information, ranks by executable size in KB, plus
some conclusions:
st-c52bli 271
st-hb-msvc 566
mt-hb-msvc 586
st-hb-bcc 629
mt-hb-bcc 652
st-hb-pocc 669
mt-hb-pocc 695
st-hb-ow 760
mt-hb-ow 807
st-hb-icc 811
mt-hb-icc 843
st-xhb-xcc 962
st-hb-mingw432 1076
st-hb-mingw433 1100
mt-hb-mingw432 1136
mt-hb-mingw433 1160
mt-xpp 252 (shared)
For me the clear winner in all technical aspects is MSVC,
creating almost the quickest executables (probably LTCG
can enhance it a bit), and the smallest ones. It's also
gratis, supports x64, unfortunately it's not free software
and not multiplatform at all, but very-well supported by
3rd parties. Next one is MinGW, which is free, open source
and multiplatform, also very well supported, gives the best speed
amongst free tools (and the smallest MT overhead), but it
generates huge executables on Windows. ICC stays being
a curiosity because it's payware, Open Watcom performs
unfortunately poorly in all aspects, I'm not sure what benefit
can it do us for now, maybe in the future, or maybe it's possible
to tweak performance. BCC and POCC have similar middle-ground
performance, both closed-source and gratis, both with bugs
and largely missing support from 3rd parties, uncertain future.
POCC supports ARM and x64, uses standard COFF libs and
all editions are gratis (not just some old versions with weird
licensing), POCC can also generate proper .dlls, so it clearly
wins over BCC.
So my overall rank goes like this:
- MSVC
- MinGW (top rank, if being free software is important)
- POCC
Maybe owatcom, if it can be made faster, but otherwise,
it's unfortunately useless. I see no reason to deal with
BCC at all, since POCC is a better alternative.
Most of these isn't news, what's new is that POCC is a very
good replacement for BCC (if MSVC and MinGW isn't an option),
and the unfortunate results of Open Watcom.
[ Notice that Open Watcom's .dll support in Harbour is broken.
Anyone to help fixing it? ]
Rgds,
Viktor

Hi Marek,
Yes, I've run tests ST and MT with pocc, ow, bcc, mingw and icc for
comparison,
also included previous Clipper, xpp and xhb tests.

Here is mine, just for fun :) [ BTW, Chen, you'd wonder how
much faster Harbour would be with MSVC or MinGW. ]
