Hiding internal symbols
Hi Niels,
Tracking which internal symbols exist on different architectures to avoid
errors and warnings when generating the symbols files for Debian is a major
PITA, but I should probably give up on that and simply tag them all
"optional". But have you considered hiding them? https://developer.apple.com/
library/archive/documentation/DeveloperTools/Conceptual/DynamicLibraries/100-
Articles/DynamicLibraryDesignGuidelines.html, https://gcc.gnu.org/onlinedocs/
gcc/Common-Function-Attributes.html#Common-Function-Attributes, and gcc(1)
have some information on this.
What you do is to attach
__attribute__((visibility("default")))
to the symbols to be exported (you can of course #define a macro, say EXPORT,
with this), then compile with -fvisibility=hidden in CFLAGS.
This should be cross-platform, it sounds like, but I'm not 100% sure.

Re: [PATCH] Fix libdir definition on FreeBSD for 32-bit ABI

I tried logging in to the gcc farm machine gcc22.fsffrance.org, and config.guess says mips64-unknown-linux-gnu, probably based on uname -m saying "mips64". So changing to mips64 for the abi check should probably work. > And similar for *sparc*, just above. Unfortunately, sparcs appear to behave differently. Tried logging in to gcc210.fsffrance.org, there uname -m says "sun4u", and config.guess says "sparc-sun-solaris2.10" (not "sparc64*"). Regards, /Niels -- Niels Möller.
