Compile error on CentOS7

[zhengshuxin]

Thanks for your job, but I got a compiling error as below:

How to fix it?
Thanks.

What are your environment variables? Are you customizing the build in some way?

[zhengshuxin]

My environment is:
CentOS Linux release 7.7.1908 (Core)
gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC)

[jart]

Could you run the following command for me?

env | grep CC\|AS

If you're overriding those variables, could you unset them and retry the build?

Please confirm if it works.

[zhengshuxin]

Nothing got after I run "env | grep CC|AS" in my environment, is something wrong?

[jart]

Could you share the full output of env? Be sure to scrub it for any sensitive information.

Can the cosmopolitan be compiled on CentOS7 ? The full env shown below may give no help:

I just setup a CentOS7 VM and noticed an error: ar failed issue which is now resolved. Cosmopolitan now builds fine on RHEL7 and all tests pass. I even removed the Ragel dependency so you literally don't need to install any packages above the minimum install in order to build the entire Cosmopolitan codebase. I wasn't able to reproduce the specific error you encountered. Give this a try:

cd cosmopolitan
git pull
rm -rf o
make -j12

Thanks for the report.

[zhengshuxin]

Thank you very much. I pulled and tried again, and got the below error:

I can't reproduce this, sorry.
