Install Imager::File::PNG Manually

This section provides a tutorial example on how to install Imager::File::PNG Perl module manually from source code files on macOS. Installation failed with wrong architecture in LIBPNG library.



With the PNG library installed, we can try to install Imager::File::PNG manually.

1. Go to Imager::File::PNG Website at https://metacpan.org/pod/Imager::File::PNG.

2. Click "Download" to get the source code file, Imager-File-PNG-0.94.tar.gz.

3. Unzip and untar it to extract its source files in "Imager-File-PNG-0.94" folder.

4. Try the following commands to install it:

herong$ perl Makefile.PL --libpath=/Users/herong/lib/libpng/lib
  --incpath=/Users/herong/lib/libpng/include --verbose

PNG: building independently
PNG libpath: /Users/herong/lib/libpng/lib
PNG libpath: /Users/herong/lib/libpng/lib
PNG: Searching directories for libraries:
PNG:   /Users/herong/lib/libpng/lib
PNG: Found!
PNG incpath: /Users/herong/lib/libpng/include
PNG: Searching directories for headers:
PNG:   /Users/herong/lib/libpng/include
PNG: Found!
PNG: Generic: includes found - libraries found
Asking liblist for LD_RUN_PATH:
Potential libraries are '-L/Users/herong/lib/libpng/lib -lpng':
'-lpng' found at /Users/herong/lib/libpng/lib/libpng.dylib
Setting LD_RUN_PATH=/Users/herong/lib/libpng/lib for PNG probe
...
ld: warning: ignoring file /Users/herong/lib/libpng/lib/libpng.dylib,

   (i386): /Users/herong/lib/libpng/lib/libpng.dylib
Undefined symbols for architecture i386:
  "_png_access_version_number", referenced from:
      _main in assertlibunQkgKfm-f31b93.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1
PNG: Test code failed: Can't link/include 'png'
...

Looks like there is a problem with the libpng.dylib we generated in the last tutorial.
