In commit 9b0ac87538 ("package/netsurf:
make sure host libpng can be found"), the netsurf package was modified
to pass -L$(HOST_DIR)/lib so that libpng is found at link time.
However, this is not sufficient: for the host tool to work at runtime,
we need to have the proper RPATH encoded in the host
binary. Otherwise, building netsurf fails with:
build/Linux-framebuffer/tools/convert_image: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory
make[3]: *** [build/Linux-framebuffer/image-caret_image.c] Error 127
So basically, we need to build not only with -L$(HOST_DIR)/lib, but
with the complete HOST_LDFLAGS provided by Buildroot.
For consistency, we also use HOST_CFLAGS instead of hardcoding
-I$(HOST_DIR)/include.
It is worth mentioning that we must use single quotes here, because
the NETSURF_CONFIG variable value then gets put within double quotes
to be passed to the netsurf build system.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
