| When building FLTK 1.1 with shared libraries, I get the following error message:
g++ -L/usr/lib64 -Wl,-soname,libfltk.so.1.1 -ldl -lm -lXext -lX11 -shared -fPIC -o libfltk.so.1.1 ...
/usr/lib64/gcc/x86_64-suse-linux/4.2.1/../../../../x86_64-suse-linux/bin/ld: Fl.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
Fl.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
This error occurred with the latest svn (r5490), g++ (GCC) 4.2.1 (SUSE Linux) on x86_64.
The problem is that when linking an so, /usr/lib64 is used in the -L switch, but that directory contains an old, non PIC version of libfltk.a.
The fix (for me) was to change DSOFLAGS in makeinclude as follows:
Index: fltk-1.1/makeinclude
===================================================================
--- fltk-1.1.orig/makeinclude
+++ fltk-1.1/makeinclude
@@ -74,7 +74,7 @@ DSOCOMMAND = $(CXX) $(DSOFLAGS) -Wl,-son
# libraries to link with:
AUDIOLIBS = -lasound
-DSOFLAGS = -L/usr/lib64
+DSOFLAGS = -L.
LDFLAGS = $(OPTIM) -L/usr/lib64
LDLIBS = -ldl -lm -lXext -lX11
GLDLIBS = -lGLU -lGL -ldl -lm -lXext -lX11
This is just a hack as the real change needs to be made in the configure scripts and/or data files, but I must leave those for someone that understands them. | |
