#15 better multiarch support

[Reini Urban]

attached patch improves configure for multiarch, at least on debian.
on debian /usr/lib32 is used for 64bit arch.
try also /usr/lib/${host_cpu}-${host_os}
harmonize amd64 to x86_64
try uname -m if uname -p fails

ok I found out how to get email notifications on changes to all trackers here so delays in responding to new items should not happen anymore.

thanks

I applied most of the patch to svn trunk, just not the part where you manually symlink the macros files, because that should already be taken care of in the macros.h file with conditional includes.

please let me know if it works for you and I will close this issue.

my first comment with this information seems to be strangely missing...

thanks

I got this error with svn r5043 on debian amd64:
./configure --enable-optimization

checking for zlib libraries and header files... includes /usr/include libs /usr/lib/x86_64-linux-gnu (shared)
checking for mpfr libraries and header files... configure: error: no mpfr library found

debian only has /usr/lib/x86_64-linux-gnu/libmpfr.so.4, no libmpfr.so symlinked somewhere.

After installing the needed libmpfr-dev it worked fine (gcc/g++).
Compilation with clang++ and clang also worked fine on debian x86_64.

ok great - BTW if you use --enable-optimization then you should use --disable-debug probably

actually in that case --disable-debug is enough because then optimizations are enabled by default

thanks for the confirmation
David
