PearPC is very slow in GNU/Linux

Guest · Post by **Guest** » Mon May 17, 2004 1:22 pm

I try pearpc in linux and windows, I think the windows jitc version is veryyy fast, and in linux I compiled pearpc withc CPU=jict and is very slow, 1/3 more windows...

this is normal?

sorry for my little english

are you sure you built it right?

./configure --enable_cpu=qt --enable-cpu=jitc_x86

Yes... I sure,

is 1/3 ...Â¬Â¬Â¬ (or 1/4...)

I found the same issue it was like half speed or less. after playing around with it I found out that under SUSE 9 one of prorgram need to make JIT copy was missing so it was making the non JIT one. Install Nasm after I install it you then run:

./configure --enable-cpu=jitc_x86
make

and the program will run a lot faster

(read subject line)

well they don't.

Why not? Does it work? Is it useless?

Code: Select all

CFLAGS="-march=i686" CXXFLAGS="-march=i686" ./configure --enable-cpu=jitc_x86 --enable-gui=qt

FAILS! This should not happen!!! Learn to write autoconf! (oops, too much coffee...)

Incrementing ettiquette level...done. You look marvelous! You compute fantastic! I love your code!

Code: Select all

CC="cc -march=i686" CXX="c++ -march=i686" ./configure --enable-cpu=jitc_x86 --enable-gui=qt

Works to propagate -march=i686 to "make".

OH! MY BLUE CANDY CANE IS MOVING SO FAST NOW!

Thx it's work

PearPC is very slow in GNU/Linux

PearPC is very slow in GNU/Linux

None

Fix for this issue

CXXFLAGS and CFLAGS do not contain -march=i686
