support for cross-compilers #386

Closed BaoshanPang closed 3 years ago

BaoshanPang commented 3 years ago

It is documented there(https://github.com/rizsotto/Bear/wiki/Usage#cross-compilers): Cross compilers should work with Bear. If Bear works with a native compiler then it should work with a cross compiler too. The only catch is that Bear does not know the compiler name to recognize it, so you need to explicitly pass the compiler names. (See --use-cc, --use-c++ or --use-only flags in the help or in the manual page for more.)

But I get this error: bear --library libexec.so --use-cc xyz -- xyz Unrecognized parameter: "--use-cc" Usage: bear [--output ] [--verbose] -- ...

What's the approach now to specify a cross-compiler?

Thanks, Baoshan

Looks like the wiki is out of date. Sorry about that @BaoshanPang .

The wiki page talks about Bear 2.4 version. The 3.x you've been trying using environment variables and configuration file to detect the compiler... CC=/path/to/cross/compiler bear -- make should do the work. Or you can specify the compiler name in a configuration file (read man citnames about that).
