Re: [ft] Freetype2 compilation error

[suzuki toshiya]

Dear Amit,

Thanks! It seems that xlc's cpp cannot handle bitshift for
64-bit constants, at least, if the constants lack the suffix
for long (or unsigned long) integer. I attached yet another
testing code that the constants greater than 32-bit range
have the suffix "L" to indicate long type. Could you execute
/bin/cpp ./cpp-bitshift-test2.c
again?

Regards,
mpsuzuki
