This is critical for windows 3.1 when - using assember. The values in crypto/bn/bn.h must match the - ones requred for the assember code. (remember that if you - edit crypto/bn/bn.h by hand, it will be clobered the next time - you run Configure by the contents of crypto/bn/bn.org). - SSLeay version -o will list the compile options. - For VC-WIN32 you need bn(64,32) or bn(32,32) - For VC-W31-32/VC-WIN16 you need bn(32,32) - For VC-W31-16 you need bn(32,16) or bn(16,16) - For VC-MSDOS you need bn(32,16) or bn(16,16). - - The first number will be 2 times bigger than the second if - BN_LLONG is defined in bn.h and the size of the second number - depends on the 'bits' defined at the start of bn.h. Have a - look, it's all reasonably clear. - If you want to start messing with 8 bit builds and things like - that, build without the assember by re-generating a makefile - via 'perl util/mk1mf.pl no-asm'. -2) You tried to build under MS-DOS or Windows 3.1 using the /G3 - option. Don't. It is buggy (thats why you just got that - error) and unless you want to work out which optimising flag - to turn off, I'm not going to help you :-). I also noticed - that code often ran slower when compiled with /G3. -3) Under NT/95, malloc goes stupid. You are probably linking with - the wrong library, there are problems if you mix the threaded - and non-threaded libraries (due to the DLL being staticly - linked with one and the applicaion using another. - -Well hopefully thats most of the MS issues handled, see you in ssl-users :-). - -eric 30-Aug-1996 - -SSLeay 0.6.5 -For Windows 95/NT, add CRYPTO_malloc_init() to your program before any -calls to the SSLeay libraries.

Cygwin implements Posix/Unix + calls through cygwin1.dll, and is contrasted to Mingw32 which links + dynamically to msvcrt.dll or crtdll.dll. + + To build OpenSSL using Cygwin: + + * Install Cygwin (see http://cygwin.com/) + + * Install Perl and ensure it is in the path (recent Cygwin perl + (version 5.6.1-2 of the latter has been reported to work) or + ActivePerl) + + * Run the Cygwin bash shell + + * $ tar zxvf openssl-x.x.x.tar.gz + $ cd openssl-x.x.x + $ ./config + [...] + $ make + [...] + $ make test + $ make install + + This will create a default install in /usr/local/ssl. + + Cygwin Notes: + + "make test" and normal file operations may fail in directories + mounted as text (i.e. mount -t c:\somewhere /home) due to Cygwin + stripping of carriage returns. To avoid this ensure that a binary + mount is used, e.g. mount -b c:\somewhere /home. + + "bc" is not provided in older Cygwin distribution. This causes a + non-fatal error in "make test" but is otherwise harmless. If + desired and needed, GNU bc can be built with Cygwin without change. + + + Installation + ------------ + + If you used the Cygwin procedure above, you have already installed and + can skip this section. For all other procedures, there's currently no real + installation procedure for Win32. There are, however, some suggestions: + + - do nothing. The include files are found in the inc32/ subdirectory, + all binaries are found in out32dll/ or out32/ depending if you built + dynamic or static libraries. + + - do as is written in INSTALL.Win32 that comes with modssl: + + $ md c:\openssl + $ md c:\openssl\bin + $ md c:\openssl\lib + $ md c:\openssl\include + $ md c:\openssl\include\openssl + $ copy /b inc32\* c:\openssl\include\openssl + $ copy /b out32dll\ssleay32.lib c:\openssl\lib + $ copy /b out32dll\libeay32.lib c:\openssl\lib + $ copy /b out32dll\ssleay32.dll c:\openssl\bin + $ copy /b out32dll\libeay32.dll c:\openssl\bin + $ copy /b out32dll\openssl.exe c:\openssl\bin + + Of course, you can choose another device than c:. C: is used here + because that's usually the first (and often only) harddisk device. + Note: in the modssl INSTALL.Win32, p: is used rather than c:. + + + Troubleshooting + --------------- + + Since the Win32 build is only occasionally tested it may not always compile + cleanly. If you get an error about functions not having numbers assigned + when you run ms\do_ms then this means the Win32 ordinal files are not up to + date. You can do: + + > perl util\mkdef.pl crypto ssl update + + then ms\do_XXX should not give a warning any more. However the numbers that + get assigned by this technique may not match those that eventually get + assigned in the CVS tree: so anything linked against this version of the + library may need to be recompiled. + + If you get errors about unresolved symbols there are several possible + causes. + + If this happens when the DLL is being linked and you have disabled some + ciphers then it is possible the DEF file generator hasn't removed all + the disabled symbols: the easiest solution is to edit the DEF files manually + to delete them. The DEF files are ms\libeay32.def ms\ssleay32.def. + + Another cause is if you missed or ignored the errors about missing numbers + mentioned above. + + If you get warnings in the code then the compilation will halt. + + The default Makefile for Win32 halts whenever any warnings occur. Since VC++ + has its own ideas about warnings which don't always match up to other + environments this can happen. The best fix is to edit the file with the + warning in and fix it. Alternatively you can turn off the halt on warnings by + editing the CFLAG line in the Makefile and deleting the /WX option. + + You might get compilation errors. Again you will have to fix these or report + them. + + One final comment about compiling applications linked to the OpenSSL library. + If you don't use the multithreaded DLL runtime library (/MD option) your + program will almost certainly crash because malloc gets confused -- the + OpenSSL DLLs are statically linked to one version, the application must + not use a different one. You might be able to work around such problems + by adding CRYPTO_malloc_init() to your program before any calls to the + OpenSSL libraries: This tells the OpenSSL libraries to use the same + malloc(), free() and realloc() as the application. However there are many + standard library functions used by OpenSSL that call malloc() internally + (e.g. fopen()), and OpenSSL cannot change these; so in general you cannot + rely on CRYPTO_malloc_init() solving your problem, and you should + consistently use the multithreaded library.
