Kushal,
there are a bunch of problems with your branch due to 32bit vs. 64bit
libraries. The main issue is that in recent GNU/Linux distributions
it is common that 64bit libraries are installed in `lib64', not `lib'.
Your current setup covers `lib' only.
Attached you can find a quick patch that I used to make it work (more
or less). As you can see, I loaded a top-level snippet to get access
to the installation directories. Note, however, that this is an
ad-hoc hack that you should not commit.
What you *really* should do is to actually use the already existing
FreeType infrastructure! It is now time that you add a `tests' target
(or proper `test-xxx' subtargets – whatever you need) to a new file
`builds/tests.mk', which must be properly included in `toplevel.mk'.
. As a prerequisite (documented in the README) the user must compile
the `base' version of FreeType manually so that a DLL gets
created. This should *not* be handled automatically. And no need
to install them.
. Similarly, the `test' version of FreeType should be built with a
simple call to `make'. Again there should be no need to install
it.
. The user should then specify the `base' FreeType `.so' file using
a variable, say, `FREETYPE_BASE_DLL'.
. Similarly, I suggest to use variables for the other test
parameters. Example:
FREETYPE_BASE_DLL="/home/wl/base/libfreetype.so.6.12.5" \
PT_SIZE="15 16 17 18 19 20 22 25 30" \
DPI="72 96" \
RENDER_MODE="mono aa" \
make tests
. Alternatively, a makefile snippet, say, `tests.mk', might be
loaded that contains the above variables.
Some more issues that I've noticed.
. `sprite' should be more verbose; it should report which files are
created where.
. I think that the HTML files created by `sprite' should be put into
a separate directory, say, `make_png/html'. Maybe you are going
to create more HTML subfiles later on (e.g., one file per font)...
. Rendering modes should be names, not numbers – please adjust your
`sprite' program accordingly. [I know that the FreeType demo
programs are a bad example for this :-)]
. Please add *a lot* of comments to the C source code files so that
it is easy to understand its features.
. What values have you used for executing `runme.sh'? I tried
sh runme.sh /home/wl/freetype-2.6.5 test.ttf 20 1
and I only got
Empty Glyph in glyph-index 1
Empty Glyph in glyph-index 2
Empty Glyph in glyph-index 3
without a single image. Maybe I did something wrong?
To summarize: `sprite' compiles file, it generates an HTML file but no
images (yet).
