How do you force CLN to build in 64-bit mode?
It's the default on my platform (GNU/Linux/amd64).
None of the "obvious" things I tried worked (e.g. ./configure --build=x86_64
This "obvious" way is plain wrong. First, --build means:
`--build=BUILD-TYPE' the type of system on which the package is being configured and compiled.
So, setting this is pointless, unless you also set --host.
Secondly, the value `x86_64' is wrong. It should be CPU-OS-VENDOR. On GNU/Linux/amd64 it's x86_64-linux-gnu (or something like that).
CFLAGS=-m64 CXXFLAGS=-m64 ./configure
This one should work.
But it would fail to turn on optimization. So, better like: CFLAGS="-m64 -O" CXXFLAGS="-m64 -O" ./configure Regarding the __i386__ definition: There is code in m4/general.m4 that ought to correct the misleading uname -m output if kernelland is 64 bit and userland 32 bit. It's worked for others so far. Why does it fail for Ron? -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>
