Compiling custom 18.06.2 using menuconfing, how to disable ca-bundle?


I normally build my own image using make menuconfig for an Asus RT-N10+ router (4/32 MB), so I can remove LUCI and add cURL (for some specific scripts that require HTTPS), in order to keep the image small I have created my own 'ca-bundle' with only the 4 root certificates that I need, and put it in /files/...

In previous versions of 18.06 this worked well, but in 18.06.2 menuconfig sets 'ca-bundle' as a required dependency when cURL is selected and I can't seem to disable it (with the full ca-bundle the image will be too big to allow me to save stuff on the overlay), I've edited .config by hand by commenting out the respective line (# CONFIG_PACKAGE_ca-bundle ), however this results in this message when compiling:
"WARNING: your configuration is out of sync. Please run make menuconfig, oldconfig or defconfig!"

Is there a way to disable ca-bundle using menuconfig without disabling curl htttps support?
What's the best way to approach this?

Thanks in advance

Edit curl Makefile and remove the ca-bundle dependency from curl.

Thank you, where is it in the /openwrt dir?

Ok, found it in /package/network/utils/curl

just remove it from "DEPENDS +=" (libcurl)? There's also "CONFIGURE_ARGS += \ ...
--with-ca-bundle=/etc/ssl/certs/ca-certificates.crt " I should probably leave this one.

Sounds right to me

Thank you, that seemed to work, it now allows me to uncheck it in menuconfig.

If you put your own certificate file in files/etc/ssl/certs/ca-certificates.crt then doesn't that overwrite the one ca-bundle puts there before the firmware is built?


I don't know, I didn't actually try that, if that actually works I prefer that behaviour.

I've compiled both by editing the curl Makefile and by putting my ca-certificates.crt in files, the size of the .bin is the same in both situations, so I guess you're right and it replaces the file.
