#545 Reusing built shipped libraries

[Baykalov Pyotr]

So there are libraries shipped with GraphicksMagic so I have built it seamlessly. But those built libraries are not installed. How can I use them not just for building GraphicksMagick but for developing for Magick++ API?

What operating system and compiler are you using?

I am sorry for not mentionшng that. I am using W7 with MinGW w64, my configure command is:

../configure '--host=x86_64-w64-mingw32' '--disable-shared' --prefix=/usr/x86_64-w64-mingw32/sys-root/mingw CXXFLAGS="-flto -ffat-lto-objects -O3" && make && make install

I use host option because I am using Cygwin's MinGW. Everything builds and installs fine without errors except that I am not getting the libraries.

So you checked /usr/x86_64-w64-mingw32/sys-root/mingw/usr/lib after
'make install' and no static libraries were added by the install?

Since you are using Cygwin, the paths would need to be viewed using
the Cygwin shell (ls -l
usr/x86_64-w64-mingw32/sys-root/mingw/usr/lib),
or externally based on the real path that Cygwin is
using.

Excuse me one more time, I am confused now.
I initially thought that GraphicksMagic has libraries included (libpng, libtiff, libwebp etc) because it was built without issues. Now I understand that it was built without issues because I already have had all these libraries installed by accident beforehand. Therefore original question does not make any sense (as GraphicksMagick package does not include these libraries).

But now I have problem with GraphicsMagic library itself. Complete example:
https://pastebin.com/dXtijW01
This includes full output of configure, make, make install and compilation of demo program (line 1356, after the word "INSTALLED") which fails to link. I have also included output of other commands to make the situation more clear.

Same for shared build:
https://pastebin.com/Hjq0yN5C

So: GM configures, builds and installs but library symbols are not available.

Close this bug please because I totally forgot about that linker flags should follow compiler flags.

g++ `GraphicsMagick++-config --cxxflags --cppflags` ../Magick++/demo/button.cpp `GraphicsMagick++-config --ldflags --libs`

I have no more problems. and those which I had were not caused by GraphicksMagic in any way.
