Shouldn't it then depend on BR2_GCC_ENABLE_TLS (and the avr32 toolchain
not select it)?

It wouldn't work with external toolchains, which is the reason why I excluded the AVR32 architecture rather than using a BR2_GCC_ENABLE_TLS condition. Best regards, Thomas

Ok, but from your comment I believe it should also depend on BR2_GCC_ENABLE_TLS (E.G. it would break on other archs if you disable TLS support)? If we start having other packages needing TLS, then we should perhaps provide the option for external toolchains as well, similar to how we do for the other toolchain settings.

If we make the package depend on BR2_GCC_ENABLE_TLS, then it would no longer be visible for any external toolchain. > If we start having other packages needing TLS, then we should perhaps > provide the option for external toolchains as well, similar to how we do > for the other toolchain settings. I'm always a bit reluctant to add more and more toolchain options, since they are a pain to maintain, and do not necessarily reflect real use cases. Is it really an useful use-case to support non-TLS toolchains on architectures where TLS support is available? Best regards, Thomas

libcap-ng doesn't build on AVR32, since it requires TLS support in the compiler and C library.
