--- Code: ---CC="gcc -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe" CXX="g++ -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe -fno-exceptions -fno-rtti"
--- End code ---

I made mistake again....but this might help me. I set the flags with

--- Code: ---export CFLAGS="gcc -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe"
export CXXFLAGS="g++ -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe -fno-exceptions -fno-rtti"
SNIP
./configure --prefix=/usr/local --with-doc=no
checking for gcc... gcc
checking whether the C compiler works... no
--- End code ---

I closed the terminal to do something and when I returned, I forgot to set the flags and got past that error, but not prepared to proceed any further until hopefully I get some advice.
In repeating above configure line I got

--- Code: ---Prefix  : /usr/local
Compiler   : gcc -g -O2
--- End code ---

and that looks like it might succeed. Any chance you could supply the next best flag set to try if .....as yes I do not know if this is right....if the issue was purely flag related.

thanks for reading in any case ....packages gr* and na* relate

Juanito:
Quite a few source packages were created with autotools before aarch64 was common - if you overwrite config.guess and config.sub in the source with those from the libtool extension, it will usually fix things.

Here is the official way to get the latest and greatest config.guess and config.sub

Also, from your above example.  this is not correct.

--- Code: ---export CFLAGS="gcc -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe"
export CXXFLAGS="g++ -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe -fno-exceptions -fno-rtti"

--- End code ---

CFLAGS should not include the compiler reference

--- Code: ---export CFLAGS="-march=armv8-a+crc -mtune=cortex-a72 -Os -pipe"
export CXXFLAGS="-march=armv8-a+crc -mtune=cortex-a72 -Os -pipe -fno-exceptions -fno-rtti"

--- End code ---

There are of course a million ways to do things, it all depends on how the makefile was built.

thats great. I have a few things to try now.
