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. Environment: System: SunOS arcade 5.9 Generic_122300-13 sun4u sparc SUNW,Sun-Fire-V490 Architecture: sun4 host: sparc-sun-solaris2.9 build: sparc-sun-solaris2.9 target: sparc-sun-solaris2.9 configured with: ../src/gcc-3.4.6/configure --prefix=/sea/compilers/native/gcc-3.4.6 --with-local-prefix=/sea/local --enable-threads --enable-languages=c,c++ --disable-multilib --with-gnu-as --with-gnu-ld --with-as=/sea/compilers/native/gcc-3.4.6/bin/as --with-ld=/sea/compilers/native/gcc-3.4.6/bin/ld How-To-Repeat: Untar REXX configure --enable-32bit make
Fix: I know of no workaround.
>/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 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?
