Hi, a user of rakarrack was getting startup exception SIGILL [1].
Seems the config/make/compile process for this app checks CPU capability of the machine it is being compiled on, and applies optimisations that are available on that processor.
The user has a much older processor.
Upstream suggest [2] that distros could add a script to detect runtime CPU, and call the appropriately compiled executable.
To do that in rpm, I think I would need to call configure a second time. Also, the new compile would overwrite the first compile, so it doesn't seem that easy.
Any suggestions on a way forward ?
Rpm's and Fedora's philosophy is to let rpm specify/dictate CFLAGS, which packages are supposed to respect.
