Re: [Openexr-devel] Compile *only* static libs for OS X Uni?

[Russ]

Thanks Paul. I am able to get the libraries to compile when I run your commands 
below as a script, but not when running them against the posted download. So 
perhaps the CVS is more up-to-date than the posted build. Not sure why you 
don't have the listed --enable-osx-universal-binaries. Note that from the 
distributed directions, you'd never know about bootstrap, because it is only in 
the CVS directions.

I'm currently encountering  "different visibility" warnings, followed by 
undefined symbol errors on
Imf::Channel::Channel(Imf::PixelType, int, int)
Imf::Slice::Slice(...
Imf::OutputFile::OutputFile(...
Imf::RgbaInputFile::RgbaInputFile(...

Any hints to resolve this would be appreciated, I'm kinda fried. This was 
previously set up to compile against 1.2.2, though I think I had to build my 
own OpenEXR project to get it to work (helps with debugging anyway)

Thanks,

Russ

Hi Russ,

This seems to be working for me with a fresh download of the source from CVS:

%cvs -z3 -d:pserver:address@hidden:/sources/openexr co IlmBase
%cvs -z3 -d:pserver:address@hidden:/sources/openexr co OpenEXR

%export CXXFLAGS='-isysroot /Developer/SDKs/MacOSX10.5.sdk -arch ppc -arch i386 
-arch ppc64 -arch x86_64'
%export LDFLAGS='-Wl,-syslibroot,/Developer/SDKs/MacOSX10.5.sdk -arch ppc -arch 
i386 -arch ppc64 -arch x86_64'

%cd IlmBase
%./bootstrap
%./configure --disable-dependency-tracking
%make
%sudo make install

%cd ../OpenEXR
%./bootstrap
%./configure --disable-dependency-tracking
%make
%sudo make install

%file /usr/local/lib/libIlmImf.a
/usr/local/lib/libIlmImf.a: Mach-O universal binary with 4 architectures
/usr/local/lib/libIlmImf.a (for architecture ppc):    current ar archive
/usr/local/lib/libIlmImf.a (for architecture i386):    current ar archive
/usr/local/lib/libIlmImf.a (for architecture ppc64):    current ar archive
/usr/local/lib/libIlmImf.a (for architecture x86_64):    current ar archive

%file /usr/local/lib/libIlmImf.dylib
/usr/local/lib/libIlmImf.dylib: Mach-O universal binary with 4 architectures
/usr/local/lib/libIlmImf.dylib (for architecture ppc7400):    Mach-O 
dynamically linked shared library ppc
/usr/local/lib/libIlmImf.dylib (for architecture i386):    Mach-O dynamically 
linked shared library i386
/usr/local/lib/libIlmImf.dylib (for architecture ppc64):    Mach-O 64-bit 
dynamically linked shared library ppc64
/usr/local/lib/libIlmImf.dylib (for architecture x86_64):    Mach-O 64-bit 
dynamically linked shared library x86_64


This is all definitely harder than it needs to be; I'll see about submitting a 
patch that enables 4-way universal builds in a more user-friendly manner.  In 
the meantime, please try the above and let me know if it's not working for you.

- Paul
