[mosh-users] mosh configure failure on Darwin/PPC

[James E Keenan]

Today I attempted to build mosh from source on an older Mac, an iBook 
G4.  No binary was available at http://mosh.mit.edu/#getting for OS X 
10.4, hence the attempt to build from source.

I quickly discovered I lacked the 'protobuf' prerequisite.  I got that 
from http://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz and 
successfully built it from source and installed it (in /usr/local/bin), 
as evidenced by:

#####
$ protoc --version
libprotoc 2.5.0
#####

However, when I went back to 'mosh', my run of './configure' ended with 
the following output:

#####
configure: WARNING: C library doesn't advertise wchar_t is Unicode (OS X 
works anyway with workaround).
checking whether IUTF8 is declared... no
configure: WARNING: No IUTF8 termios mode; character-erase of multibyte 
character sequence probably does not work properly in canonical mode on 
this platform.
checking for protobuf... no
configure: error: Package requirements (protobuf) were not met:

No package 'protobuf' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables protobuf_CFLAGS
and protobuf_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
#####

Can you shed any light on:

(1) Why the protobuf package requirements were not met?

(2) What it would mean or take to set the protobuf_CFLAGS and 
protobuf_LIBS environmental variables?

Compressed config.log is attached.

Thank you very much.
