[Bug c++/34977] New: GCC 3.4.6 link fails with undefined reference to .hidden symbol __floatdidf (libgcc.a)

[gcc-bugzilla at gcc dot gnu dot org]

        Building Regina-REXX-3.4 from source distribution.  The linker fails
with the following error:

/usr/local/bin/gcc  -O2 -I/usr/local/include  -pthreads -L/usr/local/lib -o
execiser32 execiser.o -L. -lregina -lfl  -lm -lnsl -lsocket -lcrypt -ldl  
-lpthread
/usr/local/bin/ld: execiser32: hidden symbol `__floatdidf' in
/usr/local/lib/gcc/sparc-sun-solaris2.9/3.4.6/libgcc.a(_floatdidf.oS) is
referenced by DSO
/usr/local/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status

I've verified that the compiled code has undefined references to the
__floatdidf function.

This means one of the libraries are you are using did not link against libgcc. 
This is not a bug in GCC but rather how the build one of the libraries is done,
most likely regina.

Subject: RE:  GCC 3.4.6 link fails with undefined reference to .hidden symbol
__floatdidf (libgcc.a)

I now understand what was going on...

The configure script for REXX was incorrectly linking the regina.so
using 'ld' instead of 'gcc'.  Thus, all the libraries that gcc would
normally add were missing from the ld command line.

I corrected the configuration to use gcc to perform the link of
regina.so and that fixed the problem.

I've seen many threads on this issue.  Any way to publicize the
solution?

Reid
