[uClinux-dev] HTTPS library in uCLinux

[Erwin Authried]

Hi,
curl's configure works very well for cross compiling, there's no need to
change anything in the makefiles. You have to make sure that PATH, CC,
CFLAGS and LDFLAGS are set up correctly before you run configure. There
are a lot of configure options, but the most important one is:

--host=arm-elf

I have used curl without ssl, eventually you can try to configure and
build without ssl first.

Regards,
Erwin
