[Mono-dev] SGEN support when cross compiling

[Bassam Tabbara]

Thanks Rodrigo. Is there a trick then to bypass the __thread check during configuration?

./configure --host=armv5te-unknown-linux-gnueabi

Fails with:

configure: error: cannot run test program while cross compiling

I worked around it with the following:

Do others not see this?

sgen works fine on ARM and so does cross compiling to it.

Hello,

I'm working in mono master, and it looks like sgen is not support when cross compiling. Sgen requiren with-tls=__thread and during configuration a check is made if __thread is functioning and that fails with the following error when cross compiling:

configure: error: cannot run test program while cross compiling

I can work around this but disable the check during configuration, but I'm now wondering whether anyone is using sgen on ARM platforms? Are you cross compiling for those platforms? I must be missing something simple here.

Thanks!
Bassam
