Emacs 26.1: ./configure does not find my GTK

[a***@gmail.com]

I'm trying to compile from the current 26.1 tarball on CentOS.. It stops because it can't find by GTK. Anybody have similar problem?

My GTK libs are in to /usr/lib64:

-bash-4.2$ ls /usr/lib64/libgtk*
/usr/lib64/libgtk-3.so.0 /usr/lib64/libgtk-3.so.0.2200.26 /usr/lib64/libgtk-x11-2.0.so.0 /usr/lib64/libgtk-x11-2.0.so.0.2400.31

There is no GTK in my 32 bit libs, however:

-bash-4.2$ ls /usr/lib/libgtk*
ls: cannot access /usr/lib/libgtk*: No such file or directory
-bash-4.2$

When I run./configure, it does not find the 64 bit libs, apparently:

If you are sure you want Emacs compiled without an X toolkit, pass
--with-x-toolkit=no
to configure. Otherwise, install the development libraries for the toolkit
that you want to use (e.g. Gtk+) and re-run configure.
-bash-4.2$

I did try "yum install gtk+", and it did a bunch of work, but it made no difference. I even tried installing "xaw" from yum, 'cause I saw ./configure was looking for it, but that made no difference either.

I tried setting LD_LIBRARY_PATH, but it did not help

-bash-4.2$ echo $LD_LIBRARY_PATH
/usr/lib64:/usr/lib:/usr/local/lib64:/usr/local/lib
-bash-4.2$

My /etc/ld.so.conf is

-bash-4.2$ cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/lib64
/usr/lib
-bash-4.2$ cat /etc/ld.so.conf.d/*.conf
/usr/local/lib
/usr/local/lib64
/usr/local/lib
/usr/local/lib64
/usr/local/lib
/usr/local/lib64
/usr/lib64/mysql
/usr/pgsql-9.4/lib
-bash-4.2$

It seems like emacs ./configure really doesn't know how to deal with the 64 bit libraries??

Works fine for me on RHEL 7.5.
You seem to be jumping to a conclusion about 64-bit libs based on no evidence.
You can check config.log to see the precise reason a configure test failed.

You can perhaps shortcut the whole process by running:
yum-builddep emacs
as suggested in the INSTALL file.

Try to see in which directory libXaw is.

sudo updatedb ; locate libXaw.so

Thanks, cool command - I didn't know that one..
