Hi Tamas, I tried the commands you suggested but the arch of the generated lib is unaffected on my machine:
Bedarthas... bedartha$ CFLAGS="-arch i386" CXXFLAGS="-arch i386" ./configure
bedartha$ make
bedartha$ file src/.libs/libigraph.0.dylib
src/.libs/libigraph.0.dylib: Mach-O 64-bit dynamically linked shared library x86_64 The detailed shell text is attached.

Hi, Okay, this time I'm trying it on my own machine:
First, I download igraph and extract it. Then I do this (an alternate way of
specifying compile flags at configuration time):
$ CFLAGS="-arch i386" CXXFLAGS="-arch i386" ./configure
$ make Then I check the architecture of the generated lib:
$ file src/.libs/libigraph.0.dylib
src/.libs/libigraph.0.dylib: Mach-O dynamically linked shared library i386 Then I install it and check whether it's really installed:
$ make install
$ file /usr/local/lib/libigraph.0.dylib
/usr/local/lib/libigraph.0.dylib: Mach-O dynamically linked shared library i386 Let me know if this does not work for you.
and repeated the commands. But the error remains the same - only that the "gcc-4.0" phrase is replaced with "gcc-4.2":
Good, at least it's trying it with gcc-4.2 and not gcc-4.0. The funny thing
is that I _do_ have /usr/bin/gcc-4.2 on my machine:
$ ls -la /usr/bin/gcc-4.2
-rwxr-xr-x 1 root wheel 113024 May 16 06:37 /usr/bin/gcc-4.2
It is not a symlink to llvm-gcc-4.2, so I have a non-LLVM gcc from somewhere
(as well as the LLVM-based one). At this point I'm a bit stumped as I don't
know where did I get it from -- as far as I remember, I only installed the
XCode Developer Tools. Have you installed that already?
