#44490: libtool build compile error while building poppler
------------------------+--------------------------------
 Reporter:  mparente@…  |      Owner:  macports-tickets@…
     Type:  defect      |     Status:  new
 Priority:  High        |  Milestone:
Component:  ports       |    Version:  2.3.1
 Keywords:              |       Port:  grapviz/poppler
------------------------+--------------------------------
 I was no table to find this error in another ticket.
 I was installing graphviz and the installation hangs while building
 poppler-0.26.3_0.darwin_11.x86_64.tbz2
 I checked the main.log for poppler and it looks like it hangs while
 building libtools.
 If I clean all the packages and unistall poppler, upgrade etc. the
 main.log file hangs to a different part of the compilation associated to
 build libtool

 this is where it hang one time :
 :info:build CairoOutputDev.cc:1653:29: warning: cast from 'unsigned char
 *' to 'uint32_t *' (aka 'unsigned int *') increases required alignment
 from 1 to 4 [-Wcast-align]
 :info:build     uint32_t *source_data =
 (uint32_t*)cairo_image_surface_get_data(source);
 :info:build
 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 :info:build CairoOutputDev.cc:2417:12: warning: cast from 'unsigned char
 *' to 'unsigned int *' increases required alignment from 1 to 4 [-Wcast-
 align]
 :info:build     dest = (unsigned int *) (buffer + y * row_stride);
 :info:build            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 :info:build CairoOutputDev


 this is another time

 :info:build libtool: compile:  /usr/bin/clang++ -DHAVE_CONFIG_H -I. -I..
 -I../poppler -I.. -I../goo -I/opt/local/include/libpng16
