Message-Id: <[🔎] 199908241737.KAA32596@opus.davidb.org>
To: submit@bugs.debian.org
Subject: libieee.a and libm.so shared problem.
From: David Brown <ug-debianbug@davidb.org>
Package: libc6
Version: 2.1.2-0pre10
I discovered this while trying to build the TK library for Erlang.
If when making a shared library, -lm is referenced before -lieee, a
strange error occurs.
--t1.c----------------------------------------------------------------------
/* A very small shared library. */
nothing ()
{
}
--build------------------------------------------------------------
gcc -c -o t1.o t1.c -fPIC
gcc -shared -o mylib.so t1.o -lm -lieee
----------------------------------------------------------------------
Running build on the given file produces the following error:
----------------------------------------------------------------------
+ gcc -c -o t1.o t1.c -fPIC
+ gcc -shared -o mylib.so t1.o -lm -lieee
/usr/bin/ld: mylib.so: undefined versioned symbol name _LIB_VERSION@@GLIBC_2.0
/usr/bin/ld: failed to set dynamic section sizes: Bad value
collect2: ld returned 1 exit status
----------------------------------------------------------------------
If I swap -lieee and -lm, then it builds fine.
