Shouldn't this be self.get_config_option()? :) This is the problem the CI is complaining about.

[theotherjimmy]

thanks @screamerbg !

There's one PR to change the name of the config (#1968), we should wait to see what's the final name of the config header file.

I'll fetch this and test locally. The CI tests results are good.

cfg is not defined in this context NameError: global name 'cfg' is not defined. should be config

[theotherjimmy]

you're right. the rebase renamed it to config.

[0xc0170]

The uvision requires a fix, it does not use progen_flags() function, like the rest of exporters do, thus it does not get mbed config into c_flags.

I exported to IAR, c_flags look good, not certain if preinclude should be together with mbed_conf, as this puts them on the lines in the misc options in the IDE : --preincludembed_conf.h

{'c_flags': ['--preinclude', 'mbed_conf.h'], 'asm_flags': [], 'common_flags': ['--no_wrap_diagnostics', '-e', '--diag_suppress=Pa050,Pa084,P
a093,Pa082'], 'ld_flags': ['--skip_dynamic_initialization', '--threaded_lib'], 'cxx_flags': ['--guard_calls', '--preinclude', 'mbed_conf.h']
}                                                                                                                                           

Plus now that we have this header file, Warning[Pe047]: incompatible redefinition of macro "UNITY_INCLUDE_CONFIG_H" C:\2\mbed-blinky-morpheus\projectfiles\iar\mbed_conf.h 10

I think we need a new attribute for exporters, something like support_config_header, since we're not going to convert all of them to use prefix headers at once. This will help in eliminating the duplication.

[theotherjimmy]

I can't push to this branch anymore. It's claiming that I don't have permission.

[theotherjimmy]

We could.

@theotherjimmy Please always use the forked branches. Anyway, seems like there was a change within the permission, I don't know :( The fastest way would be to use your own fork and replace this PR with a new one.

[theotherjimmy]

discussion should follow on #1975
