| The CMake build system links e.g. libfltk_images.so with libfltk.a which pulls in non PIC object in that shared library.
The attached patch fixes that and makes sure that all the libfltk_*.so files link with libfltk.so, rather than libfltk.a. | |

| Would like to accept the patch, but would like to see the errors and error replication commands so that I can verify the problem, and then verify the patch fixes the problem. | |

| OK, nevermind, maybe this is what I was looking for..
Using these commands to build fltk with cmake:
mkdir unix; cd unix; cmake -D OPTION_BUILD_SHARED_LIBS=on ..
make
Without the patch, the above dies with:
[ 71%] Building CXX object src/CMakeFiles/fltk_forms_SHARED.dir/forms_timer.cxx.o
Linking CXX shared library ../lib/libfltk_forms.so
/usr/bin/ld: ../lib/libfltk.a(Fl.cxx.o): relocation R_X86_64_32S against `.bss' can not be used when making a shared object; recompile with -fPIC
../lib/libfltk.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [lib/libfltk_forms.so.1.3] Error 1
make[1]: *** [src/CMakeFiles/fltk_forms_SHARED.dir/all] Error 2
make: *** [all] Error 2
..and with patch applied, builds without errors.
Fixed in SVN (r9920), marked active, holding for replies before closing. | |

| That was one possible issue, yes. The other was a problem with GNU binutils for solaris, which create bad .so files when you link non-PIC stuff into .so files. | |
