# 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 eric 25-Jun-1997 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.
