aarch64-xilinx-linux-gfortran: command not found
seems like user error.

FYI
target system: arm64-xilinx-linux
build system: ubuntu 16.04
yocto version: zeus (git commit id unkown, because xilinx provides it)
meta-ros version: https://github.com/ros/meta-ros/tree/zeus, git_commit_id
5707a46
action: use xilinx "petalinux-tools" (wrapping on bitbake) to integrate
meta-ros into xilinx device.

I think aarch64-xilinx-linux-gfortran is the gfortran used in target system, so
it can't be found in build system, which is user system.
Do you know why gfortran is thought to be misconfigured as indicated by
"/home/kn/xlxnew/petalinux/map_loc_os/zcu104/build/tmp/work/aarch64-xilinx-linux/libgfortran/9.2.0-r0/gcc-9.2.0/build.aarch64-xilinx-linux.aarch64-xilinx-linux/aarch64-xilinx-linux/libgfortran/config.log"
(attached as "gfortran config log") ?

I grep "command not found" and find more suspectible items, especially item
"19":
    ac_cv_fc_compiler_gnu=no
    ac_cv_func_dlopen=no
    ac_cv_func_shl_load=no
    ac_cv_header_minix_config_h=no 
    ac_cv_lib_dld_shl_load=no
    ac_cv_prog_fc_g=no
    lt_cv_archive_cmds_need_lc=no
    lt_cv_prog_compiler_c_o_FC=no
    lt_cv_prog_compiler_rtti_exceptions=no
    lt_cv_prog_compiler_static_works_FC=no
    lt_cv_shlibpath_overrides_runpath=no
    enable_static='no'

I googled "ac_cv_fc_compiler_gnu", think it means GNU Fortran Compiler. If
true, the fortran compiler is not enabled?

For detailed suspectible items, see below (grep from "gfortran config log"): 

1. --enable-version-specific-runtime-libs is no

2. "enable maintainer-specific portions of Makefiles" is no

You need to run configure in the toplevel directory.

erh... I don't know what to do to run configure in the toplevel directory.

I have another project last week, so sorry for the late reply.

I've tried, but still failed. 
Warnings and errors are as follows(searched from log.do_configure):

   1. configure: WARNING: unrecognized options: --disable-dependency-tracking,
--with-libtool-sysroot, --enable-languages, --enable-threads,
--enable-default-pie, --enable-c99, --enable-long-long, --enable-symvers,

--enable-libitm, --disable-bootstrap, --disable-libmudflap, --with-system-zlib,

--with-build-sysroot, --disable-nls, --with-glibc-version,
--enable-initfini-array, --enable-__cxa_atexit

   2. configure: error: GNU Fortran is not working

   3. libtool.m4: error: problem compiling FC test program

Any ideas?

'-qversion'; did you mean '--version'?
   aarch64-xilinx-linux-gcc: fatal error: no input files

These seem user's errors. Why do you want to use

--sysroot=/home/base/zynqmp/build/tmp/work/aarch64-xilinx-linux/libgfortran/9.2.0-r0/recipe-sysroot?

If this not a user's error, it is at least a target problem.

It is caused by xilinx bsp setting. Close for now.
