How to build png22pnm for Mac OS X? #48

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

I'm running Mac OS X 10.7.0 and would like to use pdfsizeopt. I've got 
everything going execept the png22pnm binary because it isnt included for 
sam2p. Where do I get the sourcefiles or a working binary?

Build it from source. You will need libpng as well. Get the source of png22pnm 
from here: http://sam2p.googlecode.com/files/tif22pnm-0.12.tar.gz .

To make future installations easier, I've uploaded prebuilt Mac OS X binaries 
for sam2p and png22pnm:

http://pdfsizeopt.googlecode.com/files/png22pnm-darwin
http://pdfsizeopt.googlecode.com/files/sam2p-darwin

You don't have to compile these if you don't want to. See 
http://code.google.com/p/pdfsizeopt/wiki/InstallationInstructions how to use 
the binaries above with pdfsizeopt.

Thanks. When I try to build png22pnm from source, the bash-script "do.sh" tells 
me "status png22pnm: skipped". Any suggestions? Also one more question 
regarding the compression optimization: every pdf I run through pdfsizeopt 
appears to be just slightly smaller then the original (see the attachment for 
further information). It seems that jbig2 isn't executed properly, but it's 
working when run as a single command. The only why to compile it was through a 
homebrew formula front Misty De Meo:

Do you have a darwin binary for jbig2enc?

Wrong URL for the formula, here is the new one:

Has the png22pnm problem been solved for you with the binaries I have provided?

> the bash-script "do.sh" tells me "status png22pnm: skipped". Any suggestions?

Most probably the bash script hasn't been properly written -- or you don't have 
libpng installed. Feel free to analyze the script if its output is not verbose 
enough.
Is this a blocker for you? Doesn't the precompiled binary work?

About your jbig2 problem: please create another issue for it. Please attach a 
small input .pdf. Please copy-paste the output of pdfsizeopt (rather than 
attaching).

The precompiled binary works but I just wanted to know if you could explain me 
the reason for the skipping of png22pnm.  libpng is installed so it must be 
some other reason. Here's the output from doing ./configure

The most probable reason is that the configure script cannot detect libpng 1.2, 
as indicated by:

checking for library containing png_create_read_struct... no

Where does the script search for libpng? I installed it from macports: 
https://trac.macports.org/browser/trunk/dports/graphics/libpng/Portfile .

Sorry, I don't have the capacity for providing support for this script on the 
Mac OS X. My last hint: you don't need the script at all, you can compile with

  gcc -W -Wall -s -O2 -o png22pnm png22pnm.c -lpng -lz
