nghttp2 @1.39.2_2 does not build on PPC Mac OS X 10.5.8, Leopard, because it seems to have a dependency to GCC8

[ballapete (Peter "Pete" Dyballa)]

Could be this sequence c-ares, jansson, libev, libevent, libxml2, openssl, zlib, libgcc8, libgcc7, libgcc6, libgcc, legacy-support is not correct, in the I see:

Where did you get your sequence?

port rdeps nghttp2 does not list any flavor of gcc, much less multiple versions.

Replying to Schamschula:

Where did you get your sequence?

port info nghttp2 -> Library Dependencies.

Replying to ballapete:

I think it's rather libgcc8. I see the same problem with harfbuzz.

[jmroot (Joshua Root)]

FTR, you see different dependencies because of different OS versions. nghttp2 is C++11 and the only option for that on Leopard is gcc.

[ballapete (Peter "Pete" Dyballa)]

Replying to jmroot:

I think the dependency came from libssh2. After this one was up-to-date nghttp2 built.

[jmroot (Joshua Root)]

No, it was definitely from nghttp2; libssh2 does not require C++11.
