Comments

Fixed Makefiles for correct include order of static libraries, fixed …

…error about unused 'status' variable by actually checking the status in the examples and in the test.

This fixes all the build errors I had with the library.

Failed to make mycss with latest myhtml - please sync with modest

Ubuntu 14.04 gcc version 4.8.5 branch: master

Running make returns with error when linked to latest myhtml.

first I cloned latest mycss and myhtml
build myhtml without error
then running make on mycss linking to myhtml: LDFLAGS+="-L../../../myhtml/lib" CFLAGS+="-I../../../myhtml/include" /usr/bin/make -C mycss

returns with error:

I noticed that the repo for Modest actually includes all myhtml and mycss sources. So my guess is that the current mycss repo is not up to date since it also includes "myhtml/incoming.h" which is now in "mycore".

Can you please update the repo with the latest source? That would be great!

Best, f34nk

Many properties are not recognized

I am noticing that many properties are not recognized. Simple properties like 'color' or 'border-radius' just are not showing up in the declarations.

If all the declarations are of the non-supported type, the mycss_selectors_list_t::declaration_entry property is set to NULL (which should never happen IMHO).
