Re: [ft-devel] [freetype-2.9.1] FT_Init_FreeType is missing with cc on Solaris x64

[suzuki toshiya]

Dear Kanazawa-san,

Thanks! It's my first experience to see Oracle's genuine
binutils output.

It seems that most symbols are not exposed; if you grep
the nm_list, you can find FT_Init_FreeType, but its "Bind"
attribute is LOCL (=local), not GLOB (=global).

I'm afraid something goes wrong during when private symbols
are hidden by linker script.

In the case of gcc is used, GNU libtool invokes it to make
shared library, like:
gcc -shared -fPIC -DPIC <object file> -lz -lbz2 -lpng12 \
-Wl,-soname -Wl,libfreetype.so.6 \
-Wl,-version-script -Wl,/tmp/freetype2/objs/.libs/libfreetype.ver \
-o libfreetype.so.6.6.1

libfreetype.ver is a linker script, its contents is like:
{ global:
FTC_CMapCache_Lookup;
FTC_CMapCache_New;
<snip>
FT_Vector_Unit;
TT_New_Context;
TT_RunIns;
local: *; };

But, as you can see, this "linker script" technique is
basically designed for GNU ld. I'm not sure what kind
of technologies are available on Solaris. I guess
GNU libtool fill this gap.

Now the possibilities in my mind are 2:

a) libfretype.ver (or something like that) is broken
when you build freetype-2.9.1, but it is OK for freetype-2.9.

b) your libfreetype.ver(s) are same between freetype-2.9
and 2.9.1, but compiler or linker is invoked differently.

==

to check a), I have to ask you to compare objs/.libs/libfreetype.ver
or something like that in freetype-2.9 and 2.9.1

to check b), I have to ask you to take the command execution log
for the building 2.9 and 2.9.1, and compare the command executed
to make the shared library.

If it's hard to see what I'm writing here, please let me
know (or, if you prefer discussion in Japanese).

Regards,
mpsuzuki
