building info

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.

issue:  GNU Fortran is not working
It seems like gfortran is misconfigred, as mentions below:
recipe libgfortran-9.2.0-r0: task do_configure: Failed

Attachment:
1. petalinux-build.log: use "petalinux-build" to evoke bitbake and record building info in this file.
2. gfortran_do_config_err.log: libgfortran do_configure related failure info.
3. gfortran_config.log: libgfortran configuration info.

I'm new to yocto, any hints is very appreciated. Thanks in advance!

More info here~~~

I grep "libgfortran configure info" and find "aarch64-xilinx-linux-gfortran: command not found". So aarch64-xilinx-linux-gfortran is not installed?

Also, more suspectible options are:
    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'


For detailed suspectible items, see below (grep from "libgfortran configure info"): 

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

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

To be more specific:
According to oe-core/meta/recipes-kernel/linux/linux-yocto_5.2.bb, 
LINUX_VERSION ?= "5.2.28"

According to oe-core/meta/recipes-kernel/linux/linux-yocto_4.19.bb, 
LINUX_VERSION ?= "4.19.87"
Comment 6 Randy MacLeod 2020-11-05 07:49:31 UTC 
Assigning to Ross. We think there's an example in local.conf.extended - Ross?
Comment 7 Ross Burton 2020-11-05 07:51:38 UTC 
Do you actually enable fortran support?  As per local.conf.sample.extended, you need to set:

FORTRAN_forcevariable = ",fortran"

Typically in local.conf, but the distro can do this.

Hi Ross,
There's no FORTRAN_forcevariable = ",fortran" in conf/local.conf. 

Three files constains "FORTRAN_forcevariable = ",fortran"", and they are:
1. core/meta/lib/oeqa/selftest/cases/buildoptions.py
2. meta-ros/meta-ros-common/conf/ros-distro/include/enable-fortran.inc
3. meta-openembedded/meta-oe/recipes-devtools/lapack/lapack_3.8.0.bb
Comment 10 ninos 2020-11-19 12:59:25 UTC 
Hi Ross

There are other modification I made:
1. in core/meta/recipes-devtools/gcc/gcc-9.2.inc:
   - FORTRAN = ""
   + FORTRAN = ",fortran"

Revert this.

Revert this too.

That was an example of what to put in local.conf. It's also out of date.  Revert that.

I don't know what this is meant to do as I have never used ROS.

The correct approach is to simply add FORTRAN_forcevariable = ",fortran" to your local.conf. Please do just that, reverting your other changes, and see what happens.

I've done those. Build still failed.
I've checked "run.do_configure" and "log.do_configure". They are as same as previous "run.do_configure" and "log.do_configure".

Comment 16 Ross Burton 2020-11-20 11:46:51 UTC 
I did a fresh checkout of poky zeus, added FORTRAN_forcevariable = ",fortran" to local.conf, and libgfortan builds fine.

I suggest that either you're not doing the FORTRAN assignment correctly (double check that), or either meta-ros/petalinux is breaking something.

I'd verify that plain poky/zeus works for you, and then contact xilinx for support.

Thanks. 
Did you integrate meta-ros while trying this?

What's your procedure of doing this. Maybe I can check yours with mine. 
If you're insterested in how I doing this, I can briefly describe my procedure of building.

That'll be great! Thanks again.
What's the different between plain and fresh checkout of poky/zeus?

No.  This is the main Yocto Project bugzilla for oe-core, if meta-ros is breaking the fortran support then that is a meta-ros issue and should be filed with them.  I verified that poky's fortran support is working fine.

By plain I meant "a fresh checkout with no other layers added".

Do a fresh git clone of poky and checkout zeus.  Set FORTRAN_forcevariable in local.conf, build libgfortan, verify it builds.  If that works add the pieces that you are using step by step to determine where it breaks.

Not yet.

The buildinfo log shows that you have gcc-cross from locked sstate:

you need to remove locking for gcc to respect FORTRAN variable.
Comment 23 Ross Burton 2020-12-10 16:22:44 UTC 
So yes, this is the system behaving as expected.  You're using locked sstate so you can't alter locked recipes.  You altered the base recipes, the system warned you that your changes are being ignored (the warning in the top of the build log).

If you want to rebuild gcc then unlock your sstate.

Hi Jansa
Thanks for your reply. It works.
