Re: [platform-testers] Emacs 26.2 RC1 is out!

["Nelson H. F. Beebe" <beebe@math.utah.edu>]

Eli Zaretskii <eliz@gnu.org> asks about the Solaris 11.4 problem in
building emacs-26.2: the lmcs2.h header file is not found, because it
is expected in /usr/include, but actually stored in /usr/include/lcms:

>> Does that system have an lcms2/pc file and pkg-config, and does the
>> following command show the correct -I switch:
>>
>> pkg-config --cflags lcms2

The file

	/usr/gnu/lib/pkgconfig/lcms2.pc

is supplied by Oracle in Solaris 11.4, and the command reports

	% pkg-config --cflags lcms2
	-I/usr/include/lcms

So, it seems to be a reasonable solution to have configure.ac
use pkg-config to find the needed -I option.

Eli also asks:

>> I believe Emacs 26.1 also doesn't compile on that system for the

I tried a similar build of emacs-26.1 on Solaris 11.4 with

	set path= ( /opt/developerstudio12.6/bin /bin )
	env CC=cc ./configure --prefix=$prefix --with-gnutls=no --with-pop --with-gif=no && gmake all check

It too fails with

	  CC       lcms.o
	"lcms.c", line 23: cannot find include file: <lcms2.h>

I ran

	gmake CFLAGS="-I${prefix}/include -I/usr/include/lcms"

and got a build and installation to complete.
