FLTK-full/tiny split question
« on: May 17, 2017, 04:41:01 AM »
Dear Maintainers,
I have understood the main idea to decrease size of main package ('fltk-1.3'), but add possibility use opengl/printer features fltk ('fltk-full').

But when I have tried to migrate from 7.2 - face the following issue the classes for working with images is not available:
  • Fl_RGB_Image - and system independent in-code bitmap manipulation
  • Fl_PNG_Image/Fl_JPEG_Image - working with files
the underlying libraries libpng and libjpeg-turbo is installed in 8.0, so supporting for png/jpeg available in system, but  in fltk it is not native.

Is this behavior a feature, which possibilities I have not seen or a bug?

Those classes are in the fltk_images library, on both 7.x and 8.x?

Dear Curaga, thank you for answer.

Yes, these classes are available with 7.x and 8.x and thank you for idea - so looks I have found reason:

FLTK 1.3.3 - Fl_Image::Fl_Image(int, int, int) and Fl_RGB_Image::Fl_RGB_Image(const uchar *bits, int W, int H, int D=3, int LD=0) are inline-functions.
FLTK 1.3.4 they have been moved to cxx and should be exportable from libfltk.so.1.3.

They are exported correctly in 8.x libfltk.so.1.3. Where exactly do you see this issue?

Dear Curaga,

TinyCore Linux 8.0 x86 32bit image (iso's md5 f7fee34a73a7f8e3adb30778c7c32c51) downloaded from the cite.

It's fltk-1.3.tcz (md5: 6d342fa56...) exports (I will skip all unrelated to items):
Code: newbielink:javascript:void(0); [nonactive]
$nm -D /usr/local/lib/libfltk.so.1.3 | grep Fl_Image
00043b70 T _ZN8Fl_Image10desaturateEv ; Fl_Image::desaturate()
00044192 T _ZN8Fl_Image10draw_emptyEii ; Fl_Image::draw_empty(int, int)
00044240 T _ZN8Fl_Image11RGB_scalingE14Fl_RGB_Scaling ; Fl_Image::RGB_scaling(Fl_RGB_Scaling)
0004425a T _ZN8Fl_Image11RGB_scalingEv ; Fl_Image::RGB_scaling()
000b78ec B _ZN8Fl_Image12RGB_scaling_E ; Fl_Image::RGB_scaling_
00043b6a T _ZN8Fl_Image13color_averageEjf ; Fl_Image::color_average(unsigned int, float)
00043c16 T _ZN8Fl_Image4copyEii ; Fl_Image::copy(int, int)
00044218 T _ZN8Fl_Image4drawEiiiiii ; Fl_Image::draw(int, int, int, int, int, int)
00043c6c T _ZN8Fl_Image5labelEP12Fl_Menu_Item ; Fl_Image::label(Fl_Menu_Item*)
00043b76 T _ZN8Fl_Image5labelEP9Fl_Widget ; Fl_Image::label(Fl_Widget*)
00043b84 T _ZN8Fl_Image7measureEPK8Fl_LabelRiS3_ ; Fl_Image::measure(Fl_Label const*, int&, int&)
00043b70 T _ZN8Fl_Image7uncacheEv ; Fl_Image::uncache()
00044102 T _ZN8Fl_Image9labeltypeEPK8Fl_Labeliiiij ; Fl_Image::labeltype(Fl_Label const*, int, int, int, int, unsigned int)
00043be8 T _ZN8Fl_ImageD0Ev ;Fl_Image::~Fl_Image()
00043b64 T _ZN8Fl_ImageD1Ev ;Fl_Image::~Fl_Image()
000b38a0 V _ZTV8Fl_Image ;vtable for Fl_Image

$nm -D /usr/local/lib/libfltk.so.1.3 | grep Fl_RGB_Image
00043d80 T Fl_RGB_Image::desaturate()
00043ed4 T Fl_RGB_Image::color_average(unsigned int, float)
00044272 T Fl_RGB_Image::copy(int, int)
00043b9e T Fl_RGB_Image::draw(int, int, int, int, int, int)
00043c6c T Fl_RGB_Image::label(Fl_Menu_Item*)
00043bda T Fl_RGB_Image::label(Fl_Widget*)
00043ca6 T Fl_RGB_Image::uncache()
000b5358 D Fl_RGB_Image::max_size_
000448f6 T Fl_RGB_Image::Fl_RGB_Image(Fl_Pixmap const*, unsigned int)
000448f6 T Fl_RGB_Image::Fl_RGB_Image(Fl_Pixmap const*, unsigned int)
00043d52 T Fl_RGB_Image::~Fl_RGB_Image()
00043cfc T Fl_RGB_Image::~Fl_RGB_Image()
00043cfc T Fl_RGB_Image::~Fl_RGB_Image()
000b38cc V vtable for Fl_RGB_Image
So - there are no constructors Fl_Image::Fl_Image(int, int, int) "_ZN8Fl_ImageC1Eiii" and Fl_RGB_Image::Fl_RGB_Image(unsigned char const*, int, int, int, int) "_ZN12Fl_RGB_ImageC1EPKhiiii".

But when installed fltk-full.tcz (md5sum starts 5a25) and its libfltk.so.1.3 (md5sum starts with 799)
Code: newbielink:javascript:void(0); [nonactive]
$nm -D /usr/local/lib/libfltk.so.1.3 | grep Fl_ImageC
0004b570 T _ZN8Fl_ImageC1Eiii Fl_Image::Fl_Image(int, int, int)
0004b570 T _ZN8Fl_ImageC2Eiii : Fl_Image::Fl_Image(int, int, int)

$nm -D /usr/local/lib/libfltk.so.1.3 | grep Fl_RGB_ImageC
0004b6f6 T _ZN12Fl_RGB_ImageC1EPKhiiii ; Fl_RGB_Image::Fl_RGB_Image(unsigned char const*, int, int, int, int)

The 6d.. md5sum is from the older fltk, used in 7.x. Okay, I see the problem: the isos were released a month before the fltk update, so trying to build on them (and not via a TC install) would have mismatched -dev and the normal lib.

Two solutions:
- do a normal install, and update extensions so the fltk lib is the latest one, same version as the -dev
- wait for 8.1 which would include updated extensions
