Re: Can OpenSSL be built as static libs?
Yes, Read INSTALL.XX file available with the source.

MSVC Application linked against static openssl libs is crashing
Hi All, I am facing a problem in an application (a dll) created in MSVC which links against static libeay32.lib and ssleay32.lib. Problem is that when I use this application and openssl function is called, app crashes. But when I link this application against the dlls of openssl (using the .libs which are created when we compile openssl with ntdll.mak) it works fine. What I have noticed is that when I link my application into the static openssl libraries its size is much smaller than the size of the libs. Linker pulls only that code form openssl libs which it thinks is being used in the application (this perhaps is called dead code striping). But I think there are certain methods which are used by the application (perhaps indirectly) which linker does not include in the resulting app, this results in a crash when app is executed. Or there is some other reason? In GCC on MacOSX we have a linker option -all_load which includes all the code of a static library in the application. And hence the size of the app is greater than the size of the libs put together. Is my above understanding correct, or something else is wrong? Has anyone else run into this problem? How can I use openssl static libraries in an app developed in MSVC or CodeWarrior so that I do not need to have openssl dlls on the machine?

Re: MSVC Application linked against static openssl libs is crashing
Hi Aftab, Thanks for the reply, If you are referring to compiling openssl with /MT switch then, yes, I have compiled openssl with /MT switch (thanks to Rush he had pointed this out). But because I need static library of openss so I used nt.mak file for openssl compilation. But if you mean that /MT should be used in MSVC while compiling the app which is using openssl libraries, then I have just confirmed that in c/c++ tab of project settings /MT is already spcified (because the dll which I am creating is multithread). I am using MSVC6.0 Any other idea?

Re: MSVC Application linked against static openssl libs is crashing
Thanks Brant Thomsen for the reply, My application is actually a Win32 Dynamic-Library with no MFC support. Any other idea? Thanks and regards -- Qadeer Baig On 6/6/05, Brant Thomsen [EMAIL PROTECTED] wrote: I have had problems getting OpenSSL to link correctly if MFC is being used. Try switching from static to dynamic loading of the MFC libraries and see if that solves the problem.

Re: libeay32.lib giving some link errors while using on Windows
Great thanks Rush! This exercise did solve the problems :-) Now I see that this problem with nt.mak has already been pointed out by Matyas Majzik in one of his emails to this group. Thanks and regards, -- Qadeer Baig On 6/1/05, Rush Manbert [EMAIL PROTECTED] wrote: Hi Qadeer, I just went through the exercise of building the openssl libraries for Win32 and for the Mac. I also built and installed libxml, libxslt, and xmlsec. This matters because xmlsec links against openssl. I discovered that the generated makefiles for Win32 hard code /MD into the compiler flags. This causes the link with your program to want the DLL runtime. (Note your error messages that mention dllimport.) I ran into all sorts of problems with the xmlsec link until I fixed this. I think that you can fix your problem if you edit ms\nt.mak after you run the configure. Find the line that begins with: CFLAG= /MD Change the /MD to something better, like /MT (multithreaded using LIBCMT.lib) or /ML (single threaded using LIBC.lib). Whatever you choose here must be the same as what you use for your program that links against this library. Now run the make and the install and try linking to your program. I hope this helps. - Rush __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED] __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
Re: How to link statically openssl in a dylib
Hi Rush, Your solution has been very helpful. (2) does the correct thing. It statically links against your version of libssl.a. It also acts just like it found the library because of a -lssl on the linker command line. (Only the functions that are required are pulled into your executable, NOT the entire library contents.) using -all_load link option pulls the entire contents of the static library. Thanks to all who spared time to solve my problem. -- Qadeer __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
How to link statically openssl in a dylib
Hi, I am using openssl in an application (this application actually is a .dylib on Mac OSX). Currently I am linking openssl calls by using -lssl -lcrypto linker options. Since this links openssl calls dynamcally therefor I can only use resulting application on the computers where libssl.dylib and libcrypto.dylib are already installed. Now what I want is that openssl is statically linked into my application (dll, .dylib on OSX) so that libssl.dylib and libcrypto.dylib are not required on the machines where my application is used. What linker options will I use?, XCode internally uses gcc (I believe). It will be of great help if someone can give a simple make file (or a simple xcode project). I have following libraries available: 1. libssl.dylib 2. libcrypto.dylib 3. libssl.a 4. libcrypto.a I think .a libraries will be used for static linking but how(?) so that the resulting application is a still a .dylib. Any help will be highly appreciated.

Re: How to link statically openssl in a dylib
Thank you Joseph, I also wondered to see ssl libraries in /usr/lib on my machine, when I started using ssl, but before seeing them there I had tried to compile Openssl on my machine so I thought this compilation has placed them there. But still, client says link them statically :( Regards, -- Qadeer OS X ships with openssl pre-installed so you will never find a machine that does not have the dylib's available in /usr/lib. However, the version shipped is 0.9.7b. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
