[gnutls-devel] portability problem in gnutls-3.2.7: rpl_strerror missing

[Thomas Klausner]

Hi!

gnutls decides to replace NetBSD's strerror() with its own; I guess
because this configure test fails:
checking whether strerror(0) succeeds... no

strerror(0) on NetBSD is: "Undefined error: 0"
I don't see how that is a problem, can someone explain please?

However, it later fails to link:
  CCLD     gnutls-cli-debug
../lib/.libs/libgnutls.so: undefined reference to `rpl_strerror'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Where is this function supposed to be defined?
grep -r rpl_strerror doesn't give me a hint:

gnutls-3.2.7/src/gl/string.in.h:#   define strerror rpl_strerror
gnutls-3.2.7/src/gl/string.in.h:#   define strerror_r rpl_strerror_r
gnutls-3.2.7/src/gl/string.h:#   define strerror rpl_strerror
gnutls-3.2.7/src/gl/string.h:#   define strerror_r rpl_strerror_r
gnutls-3.2.7/gl/string.in.h:#   define strerror rpl_strerror
gnutls-3.2.7/gl/string.in.h:#   define strerror_r rpl_strerror_r
gnutls-3.2.7/gl/string.h:#   define strerror rpl_strerror
gnutls-3.2.7/gl/string.h:#   define strerror_r rpl_strerror_r

Ideas?

Thanks,
 Thomas
