Compiling ZPAQ on Mac OSX 10.7.2 (Lion) gcc4.2.1 - problems!

[z3cko]

i am trying to compile ZPAQ on mac osx 10.7.2
gcc version 4.2.1 (Based on Apple Inc. build 565 (LLVM build 2336.1.00)

is there maybe a full how to somewhere out there?
i am getting the error

windows.h: No such file or directory(among other errors)


here are the steps i have taken

1. got libzpaq
2. got zpaq
3. copied both in the same directory.
4. got divsufort (2.0.0) and copied divsufsort.c in the same directory.
5. ran ./configure in the divsufort directory and copied the generated divsufort.h also in the directory.


g++ zpaq.cpp libzpaq.cpp divsufsort.c -O3 -fopenmp -s -DNDEBUG -o zpaq

here is the full error output:
http://pastie.org/3036026

anyone has an idea or pointer on how i can get zpaq compiled?

thanks a lot in advance!

wget http://mattmahoney.net/dc/libzpaq400.zip
wget http://mattmahoney.net/dc/zpaq402.zip
wget http://mattmahoney.net/dc/divsufsort200.zip
unzip libzpaq400.zip
unzip zpaq402.zip
unzip divsufsort200.zip
g++ -O3 -lpthread -s -DNDEBUG zpaq.cpp libzpaq.cpp divsufsort.c -o zpaq

Maybe add -Dunix to that if that's not enough - it worked for me on linux though.

thanks a lot for the answer - unfortunately this still does not compile on Mac OSX.

1) g++ -O3 -lpthread -s -DNDEBUG zpaq.cpp libzpaq.cpp divsufsort.c -o zpaq
produces this error message: http://pastie.org/3038357

2) g++ -O3 -lpthread -s -DNDEBUG -Dunix zpaq.cpp libzpaq.cpp divsufsort.c -o zpaq
produce a shorter error message.

libzpaq.cpp: In function ?void libzpaq::allocx(libzpaq::U8*&, int&, int)?:
libzpaq.cpp:74: error: ?MAP_ANONYMOUS? was not declared in this scope

all in all, nothing works. any other ideas?

thanks a lot in advance!

Edit/redefine that constant to MAP_ANON?

[Matt Mahoney]

Guess I need to fix that in libzpaq. MAP_ANON is deprecated, which is why I used MAP_ANONYMOUS.

I should also mention that JIT only works on x86-32 and x86-64. I have only tested in 32 bit Windows and 64 bit Linux. If it crashes, try compiling with -DNOJIT. It will be slower, but should work.

[Matt Mahoney]

I posted libzpaq v4.01 changing MAP_ANONYMOUS to MAP_ANON.

[z3cko]

Matt, thanks for the information. With -DNOJIT it actually does compile. Is there any way to fix JIT on osx?

thanks and regards,

[Matt Mahoney]

What errors do you get when compiling with -Dunix and without -DNOJIT ?
