#153 configure script uses incorrect name for tcl & tk libs

[Daniel O'Connor]

I run configure like so..
./configure --prefix=/usr/local --with-tcl=/usr/local/lib/tcl8.6 --with-tk=/usr/local/lib/tk8.6 --with-tclincdir=/usr/local/include/tcl8.6 --with-tkincdir=/usr/local/include/tk8.6 --with-tcllibdir=/usr/local/lib --with-tklibdir=/usr/local/lib --with-xftincdir=/usr/local/include --with-xftlibdir=/usr/local/lib --enable-symbols --exec-prefix=/usr/local

which shows..
...
checking for tclConfig.sh... /usr/local/lib/tcl8.6/tclConfig.sh
checking for tkConfig.sh... /usr/local/lib/tk8.6/tkConfig.sh
...

vyt this results in..
TCL_LIB_SPEC = -L/usr/local/lib -ltcl8.6
...
TK_LIB_SPEC = -L/usr/local/lib -ltk8.6

However tclConfig.sh and tkConfig.sh have the right result here..

[test12 5:52] /tmp/blt-src> . /usr/local/lib/tk8.6/tkConfig.sh
[test12 5:52] /tmp/blt-src> echo $TK_LIB_SPEC

This is on FreeBSD-12.

Does it work without the --with-tcllibdir, --with--tklibdir, --with-tclincdir, and --with-tkincdir switches? The --with-tcl and --with-tk switches should be enough. The config.sh files should provide all the information.

What's happening is that the --with-tcllibdir and --with-tkli dir switches are overriding what was found in the tclConfig.sh and tkConfig.sh files. Are there tcl and tk libraries in /usr/local/lib?

Thank you again for the bug report. Clearly I need better information how to build. I started a doc for Windows. I need to make something for Unix.

I tried with..
./configure --prefix=/usr/local --with-tcl=/usr/local/lib/tcl8.6 --with-tk=/usr/local/lib/tk8.6 --with-xftincdir=/usr/local/include --with-xftlibdir=/usr/local/lib --enable-symbols --exec-prefix=/usr/local

but it still does the same thing.
I've attached config.log if that helps.

This patch fixes it for me.

There has been some naming convention changes in several of the libraries. autoconf should have picked them all up, but I found that under Ubuntu (buster) or Debian (10.2), tcl/tk 8.6.9, I still needed to make this change:

configure.in
490c490
<     ft2_inc_spec=`freetype-config --cflags`
---
>     ft2_inc_spec=`pkg-config freetype2 --cflags`
492c492
<     ft2_inc_spec="-I${blt_with_ft2_include_dir}/freetype2 -I${blt_with_ft2_include_dir}"
---
>     ft2_inc_spec="-I${blt_with_ft2_include_dir}/freetype -I${blt_with_ft2_include_dir}"

After that, it still would not pick up the freetype library, so I had to pass this flag:

./configure --prefix=/usr --with-freetype2incdir=/usr/include/freetype2

and then everything worked like a charm. To fix the last one, it's possible that some form of pkg-config freetype2 --libs is also needed, but I could not make it work.

Ideas?
