Perhaps I spoke too soon. I got it to build a 64 bit library, which I can use to link up an executable, but when it actually gets into the curl code, it causes a bus error.

It seems that there's something wrong about the byte alignment in this library I've generated. I also compiled it with an option to allow misaligned byte accesses, and then it just crashes, so there's something bigger wrong here.

Anyone else run into byte alignment problems on a 64 bit library, or have any idea how to get rid of them?

Thanks again.

Thanks for the answers, all.

I got it all working with:

CC=cc CFLAGS="-xtarget=ultra -xarch=v9 -xstrconst -xdepend -Xa -xcode=pic32" ./configure --with-ssl=[path to ssl] --prefix=[prefix] --enable-shared --disable-ldap --disable-ipv6 --enable-thread --without-libidn --without-zlib --without-libssh2

Hope this helps someone else. Thanks again.

It's been in OpenSolaris and Nevada (future Solaris 11) since July
2007, both 32- and 64-bit, both SPARC and Intel.
