Re: Repeat request for help from icon maintainer.



Thank you so much for your help!

Removing the Msys2 versions of inkscape and then installing the windows package and adjusting my path to

    export PATH=$PATH:"/c/Program Files/Inkscape"

and then commenting out line 33 in zutil.h, recompiling and replacing pngcrush seemed to work.

I am providing details in case others have this challenge.

I am now waiting for the compile to run but it seems happy.

Thanks again!

Thanks for this.

Unfortunately, inkscape and pngcrush seem to be a work in process on Msys.

If I install the package

     $ pacman -S mingw-w64-x86_64-inkscape

and run inkscape I get the error

     $ inkscape
     C:/msys64/mingw64/bin/inkscape.exe: error while loading shared
libraries: libpoppler-89.dll: cannot open shared object file: No such
file or directory

If I build inkscape in MSYS and run make install I get

     [  0%] Built target potrace
     make[2]: Entering directory '/home/bjpic/debug'
     [  0%] Creating 48 pixel tall
     Unknown option --without-gui
     [  0%] Creating 16 pixel tall
     Unknown option --without-gui
     [  0%] Creating cleaned file

running inkscape --without-gui causes the same error.

Similarly, installing the pngcrush package in msys2 pacman -S
mingw-w64-x86_64-pngcrush results in the warning

$ pngcrush
Warning: versions are different between png.h and png.c
   png.h version: 1.6.34
   png.c version: 1.6.37

Making pngcrush under msys2 fails with a forced error.

In general it seems that many related utilities under Msys2 are a dogs

Perhaps for the moment it would be best if I simply made my bitmaps


I have no issues with inkscape and pngcrush.
- Inkscape is installed from binaries coming from Inkscape site.
- pngcrush was built on msys2 by me from pngcrush sources.
This is a very small program and it is easy to build on msys2.
However, to build it, remove (or comment) the line 33 in zutil.h
"typedef long ptrdiff_t;  /* guess -- will be caught if guess is wrong */"
to avoid a conflict with a mingw included file.

the first useful line of my script running cmake is:
export PATH=$WXMSW:$PATH:/d/inkscape:/d/pngcrush

You will have to remove inkscape from msys2.

Attached, my msys2 script to run cmake.

Good luck...

I emailed earlier because when I follow the directions to create a new
icon under MSYS2 it fails.

This means that either

1) the directions are wrong or
2) I am following them incorrectly.

Perhaps an icon maintainer can get in contact with me and work through

I basically need to clone the icons annotate_right_down and
annotate_down_right rotated 90, 180, and 270 degrees. Not complicated.


Hi Brian,

To build the .cpp files the option MAINTAIN_PNGS must be set to ON in

1 - To avoid cache issues, delete your current CMakeCache.txt file in
your build directory.
2 - Run cmake as before, with option -DMAINTAIN_PNGS=ON to recreated the

After that you should be able to rebuild/create the .cpp bitmap files.
