However, the supposed cross-compiler seems to be trying to build for linux.

A single compiler binary can always compile for all supported targets of
that processor. So as long as all the units are available you simply
need to pass "-Twin64" as additional parameter to compile for x86_64-win64.

Thanks Sven,
I have resolved this issue. It was due to having a distro based fpc
which installs in /usr/lib64 and svn trunk which installs in /usr/lib .
Once I reunited both under /usr/lib64 I was able to compile native and
cross versions. of my test prog.
I'm a little unclear when you say any compiler can always compile for
all supported targets. All I have read indicates a specific make
sequence to get a cross compiler.
make all OS_TARGET=win32 CPU_TARGET=i386
make crossinstall OS_TARGET=win32 CPU_TARGET=i386
Could you clarify ?
Thanks.
