7.55.1 fails to build on Mac OS X PowerPC, expected specifier-qualifier-list before ‘curl_off_t’ #1797

I did this

./configure and make

I expected the following

successful build

curl/libcurl version


operating system

Mac OS X 10.5.8 PowerPC

Here is a log of the failure:


The errors begin with:

../include/curl/curl.h:174: error: expected specifier-qualifier-list before ‘curl_off_t’

I suspect #1774 caused this. 7.55.0 built successfully on the same system.

I'm not in front of a PowerPC system right now, but sources on the Internet show that a PowerPC Mac running Mac OS X 10.4 defines __ppc__ and __POWERPC__ but not __powerpc__.

Is that using gcc?

How about fixing it like this:

Is that using gcc?

Yes, the Apple-modified version of gcc 4.2.1 that comes with Xcode 3.1.4. Apple-modified GCC is the default compiler on Mac OS X 10.6 and earlier.

How about fixing it like this:

That was going to be my suggestion. I've seen other code on the Internet that also checks for __PPC__, but I don't know what systems that's for.

curl/system.h: check for __ppc__ as well
... regression since issue #1774 (commit 10b3df1) since obviously
some older gcc doesn't know __powerpc__ while some newer doesn't know
__ppc__ ...

Fixes #1797
