- See troubleshooting if you get error messages about functions not

- 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\openssl\* 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 Git 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.
