#30127: arm-elf-gcc @4.6.0 presence of hdf4 port prevents arm-elf-gcc from building ---------------------------------------+------------------------------------ Reporter: michael@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.9.2 Keywords: | Port: arm-elf-gcc ---------------------------------------+------------------------------------ Description changed by ryandesign@…: Old description:

If HDF4 is installed (and activated), then arm-elf-gcc (and possibly other gcc versions) fail to build:

{{{ :info:build /usr/bin/gcc-4.2 -I/opt/local/include -c -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-ma ..... :info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_mirror.aarnet.edu .au_macports-portfiles_cross_arm-elf- gcc/work/gcc-4.6.0/gcc/config/arm/arm.c -o arm.o :info:build In file included from /opt/local/include/hdf.h:20, :info:build from /opt/local/include/df.h:35, :info:build from /opt/local/var/macports/build/_opt_local_var_macports_sources_mirror.aarnet.edu .au_macports-portfiles_cross_arm-elf- gcc/work/gcc-4.6.0/gcc/config/arm/arm.c:55: :info:build /opt/local/include/hdfi.h:1613:29: error: attempt to use poisoned "malloc" :info:build /opt/local/include/hdfi.h:1614:29: error: attempt to use poisoned "calloc" :info:build /opt/local/include/hdfi.h:1616:29: error: attempt to use poisoned "realloc" :info:build /opt/local/include/hdfi.h:1636:37: error: attempt to use poisoned "strdup"

}}}

De-activating the HDF4 port before installing gcc fixes this problem.

This seems to be the result of: * unfortunate naming of a global header by hdf (fixed in HDF5) * poor ordering of header paths (gcc internal paths should have priority -- the header is included from arm.c with double quotes not angle brackets, ie #include "df.h" not #include <df.h>)

Can this be fixed with, at the very least, a warning to the unwary? The df.h header is not installed by gcc so it should be safe to reactivate HDF4.
