Cross build from RasPi5/Linux/Aarch64 to -m=rv64le FAILS [zlib]

[KenDickey]

Greetings,

It has been several years since I used Chez and am interested in a build for StarFive 2 [RV64G].

I am probably doing something incredibly stupid and would appreciate any help.

Thanks!

rv64-make.out.txt

=============
RasPiOS5:Arm64:~/Scheme/ChezScheme >>> ./configure -m=rv64le

Configuring for rv64le, and will create boot files via pb

RasPiOS5:Arm64:~/Scheme/ChezScheme >>> make

bin/zuo rv64le MAKE="make"
checking boot files for rv64le against pb
... ... ...
running pb/bin/pb/scheme to build xc-rv64le/boot/rv64le/heapcheck.inc
cd rv64le/zlib && ./configure
Compiler error reporting is too harsh for ./configure (perhaps remove -Werror).
** ./configure aborting.
libz configure failed

Ah. "configure.log" shows:

gcc -c -mabi=lp64d -O2 ztest169441.c
gcc: error: unrecognized argument in option ‘-mabi=lp64d’
gcc: note: valid arguments to ‘-mabi=’ are: ilp32 lp64; did you mean ‘lp64’?
(exit code 1)

Perhaps a cross-compile tool issue?

tried
./configure --cross -m=trv64le CFLAGS="-march=rv64gc" CC_FOR_BUILD=gcc
but no joy.

However, I discovered that you cleverly used the pb Scheme interpreter to bootstrap natively on RV64GC ! 8^| 8^O 8^) ;^)

So I now have Chez Scheme working on a StarFive Visionfive 2.

Thanks for all the great work!!!
