Re: [Plib-users] (newbie) Compile errors when installing PLIB exa mples + documentation.

[Fay J. F Dr C. U. AFSEO/SK <joh...@eg...>]

Otto,

	Please pardon my delay in answering you.

	From your description below, it looks a lot like you are trying to
compile the "ul" library with a C program instead of with a C++ =
program.
The C language does not distinguish between "inline void
ulEndianSwap(unsigned int *x)" and "inline void ulEndianSwap(unsigned =
short
*x)" while C++ does.  That will cause the compiler errors you are =
getting.

	Why the compiler is doing this with the example files is beyond me.

Subject: [Plib-users] (newbie) Compile errors when installing PLIB =
examples
+ documentation.

It seems that I have managed to install PLIB successfully, because =
although
the terminal displayed strange information, all the files had been =
installed
in their correct locations.

But now, when installing the PLIB examples + documentation package, I =
get
problems.

Calling ./configure

Something seemed to go wrong in the middle of the procedure, but it =

I don't know if I did something wrong or if it's the source, but it =
looks
like there are some errors in the source code. I don't know... As =
always, my
platform is MacMini G4 SD with MacOS X 10.4.6.

So, will I have to edit the source files by hand (again!) or is there =
an
easier way?
