Instructions for building Vectaport software on Solaris 2.6:
Revised April 1999.

0. Create /usr/local if it doesn't already exist.

1. Obtain a gzip Solaris binary from a GNU ftp site that has binaries.
You will need to use the -d option to decompress files. Here is a sun4
binary that still works on Solaris:

	http://www.cl.cam.ac.uk/ftp/hvg/gzip/gzip-sun4

2. acquire a binary gcc for solaris 2.6 from:

http://metalab.unc.edu/pub/solaris/sparc/GNUgcc.2.8.1.SPARC.Solaris.2.6.pkg.tgz

binaries for egcs-1.0.3 would probably work as well.  

3. Add /usr/local/bin, /usr/ccs/bin and /usr/X/bin in that order to
the front of your PATH in the .profile file in your home directory.
Re-login or set it in the current shell before building

4. Install the GNUgcc package:
	zcat GNUgcc.2.8.1.SPARC.Solaris.2.6.pkg.tgz | tar xvf -
	su c "pkgadd -d`pwd` GNUgcc"
   Make a symbolic link from /usr/local/bin/gcc to /usr/local/bin/cc.

5. Obtain libstdc++-2.8.1.tar.gz from a GNU ftp site.  If you desire
to build gcc from source, obtain gcc-2.8.1.tar.gz as well.
Alternately you can obtain a recent copy of egcs.  You might have less
problem with optimization bugs with egcs.

6. Skip this item if you don't care about building gcc from source.
Untar gcc-2.8.1, cd there and configure it without GNU as and GNU ld:
	./configure
	make LANGUAGES=c
	make stage1
	make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2"
	make install CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2"

7. Build and install libstdc++-2.8.1 in the default manner.

8. Build clippoly.
	Edit Makefile:
		Add -fPIC to CFLAGS and CCFLAGS
	make
	Make a shared library: gcc -shared -o libclippoly.so *.o

9. Build ACE-4.6
	Use ace/config-sunos5.5-g++.h as ace/config.h
	Use include/makeinclude/platform_sunos5_g++.GNU as 
	    include/makeinclude/platform_macros.GNU
	Edit platform_macros.GNU PIC line to look like this:
		PIC = -fPIC
	Edit ace/Name_Request_Reply.h line 27 (after includes & before classes)
		#undef MAX_NAME_LEN
	make

10. Build and install qhull in the default manner.

11. Obtain a copy of ivtools from http://www.vectaport.com/ivtools.
If you are building ivtools-0.7.5, read the additional instructions at
http://www.vectaport.com/ivtools/release-note-0.7.5.html (subsequent
versions will have these things fixed).  Read and follow the instructions in
the INSTALL file.  The steps are:

	a. Configure with ./configure. Here is an example of
	using the configure script:

	./configure --with-ace=/proj/ACE_wrappers --with-clippoly=/proj/clippoly --enable-install-relative --enable-use-rpath

	b. Build with:  make World

	c. Install with:  su -c "make install"


12. Build and install PROJ.4.3.3 in the default manner.

13. Optionally build MesaLib-3.0 and vtk-2.2.  For Mesa use the
 "make sunos5-x11r6-gcc-sl" command.  For vtk edit the Mesa pathnames
(MESA_INCLUDE and MESA_LIB) in user.make and then use --with-mesa and
--with-shared for configure:

	./configure --with-mesa --with-shared

14. Obtain vhclmaps from http://www.vectaport.com/vhclmaps/.  If you
are building vhclmaps-0.7, the additional instructions described above
for ivtools-0.7.5 apply as well. Read and follow the instructions in
the INSTALL file.  The steps are:

	a. Configure with ./configure. Here is an example of
	using the configure script:

	./configure --with-ace=/proj/ACE_wrappers --with-clippoly=/proj/clippoly --enable-install-relative --enable-use-rpath --with-vtk=/proj/vtk --with-opengl=/proj/Mesa-3.0 --with-ivtools=/proj/ivtools-0.7 

	b. Build with:  make World

	c. Install with:  su -c "make install"
