# Installation of SSLeay.
# It depends on perl for a few bits but those steps can be skipped and
# the top level makefile edited by hand
# When bringing the SSLeay distribution back from the evil intel world
# of Windows NT, do the following to make it nice again under unix :-)
# You don't normally need to run this.
sh util/fixNT.sh # This only works for NT now - eay - 21-Jun-1996
# If you have perl, and it is not in /usr/local/bin, you can run
perl util/perlpath.pl /new/path
# and this will fix the paths in all the scripts. DO NOT put
# /new/path/perl, just /new/path. The build
# environment always run scripts as 'perl perlscript.pl' but some of the
# 'applications' are easier to usr with the path fixed.
# Edit crypto/cryptlib.h, tools/c_rehash, and Makefile.ssl
# to set the install locations if you don't like
# the default location of /usr/local/ssl
# Do this by running
perl util/ssldir.pl /new/ssl/home
# if you have perl, or by hand if not.
# If things have been stuffed up with the sym links, run
make -f Makefile.ssl links
# This will re-populate lib/include with symlinks and for each
# directory, link Makefile to Makefile.ssl
# Setup the machine dependent stuff for the top level makefile
# and some select .h files
# If you don't have perl, this will bomb, in which case just edit the
# top level Makefile.ssl
./Configure 'system type'
# The 'Configure' command contains default configuration parameters
# for lots of machines. Configure edits 5 lines in the top level Makefile
# It modifies the following values in the following files
Makefile.ssl CC CFLAG EX_LIBS BN_MULW
crypto/des/des.h DES_LONG
crypto/des/des_locl.h DES_PTR
crypto/md2/md2.h MD2_INT
crypto/rc4/rc4.h RC4_INT
crypto/rc4/rc4_enc.c RC4_INDEX
crypto/rc2/rc2.h RC2_INT
crypto/bf/bf_locl.h BF_INT
crypto/idea/idea.h IDEA_INT
crypto/bn/bn.h BN_LLONG (and defines one of SIXTY_FOUR_BIT,
SIXTY_FOUR_BIT_LONG, THIRTY_TWO_BIT,
SIXTEEN_BIT or EIGHT_BIT)
Please remember that all these files are actually copies of the file with
a .org extention. So if you change crypto/des/des.h, the next time
you run Configure, it will be runover by a 'configured' version of
crypto/des/des.org. So to make the changer the default, change the .org
files. The reason these files have to be edited is because most of
these modifications change the size of fundamental data types.
While in theory this stuff is optional, it often makes a big
difference in performance and when using assember, it is importaint
for the 'Bignum bits' match those required by the assember code.
A warning for people using gcc with sparc cpu's. Gcc needs the -mv8
flag to use the hardware multiply instruction which was not present in
earlier versions of the sparc CPU. I define it by default. If you
have an old sparc, and it crashes, try rebuilding with this flag
removed. I am leaving this flag on by default because it makes
things run 4 times faster :-)
# clean out all the old stuff
make clean
# Do a make depend only if you have the makedepend command installed
# This is not needed but it does make things nice when developing.
make depend
# make should build everything
make
# fix up the demo certificate hash directory if it has been stuffed up.
make rehash
# test everything
make test
# install the lot
make install
# It is worth noting that all the applications are built into the one
# program, ssleay, which is then has links from the other programs
# names to it.
# The applicatons can be built by themselves, just don't define the
# 'MONOLITH' flag. So to build the 'enc' program stand alone,
gcc -O2 -Iinclude apps/enc.c apps/apps.c libcrypto.a
# Other useful make options are
make makefile.one
# which generate a 'makefile.one' file which will build the complete
# SSLeay distribution with temp. files in './tmp' and 'installable' files
# in './out'
# Have a look at running
perl util/mk1mf.pl help
# this can be used to generate a single makefile and is about the only
# way to generate makefiles for windows.
# There is actually a final way of building SSLeay.
gcc -O2 -c -Icrypto -Iinclude crypto/crypto.c
gcc -O2 -c -Issl -Iinclude ssl/ssl.c
# and you now have the 2 libraries as single object files :-).
# If you want to use the assember code for your particular platform
# (DEC alpha/x86 are the main ones, the other assember is just the
# output from gcc) you will need to link the assember with the above generated
# object file and also do the above compile as
gcc -O2 -DBN_ASM -c -Icrypto -Iinclude crypto/crypto.c
This last option is probably the best way to go when porting to another
platform or building shared libraries. It is not good for development so
I don't normally use it.
To build shared libararies under unix, have a look in shlib, basically
you are on your own, but it is quite easy and all you have to do
is compile 2 (or 3) files.
For mult-threading, have a read of doc/threads.doc. Again it is quite
easy and normally only requires some extra callbacks to be defined
by the application.
The examples for solaris and windows NT/95 are in the mt directory.
have fun

IRIX 5.x will build as a 32 bit system with mips1 assember.
IRIX 6.x will build as a 64 bit system with mips3 assember. It conforms
to n32 standards. In theory you can compile the 64 bit assember under
IRIX 5.x but you will have to have the correct system software installed.
