I wanted to install openssl on windows 7 Home Premium 64 bit , i have downloaded the openssl package and extracted it as well in the c directory however i am not able to find something that shows how to link the openssl in Netbeans 7.1.1 . I have got MinGW(4.6.1) compiler with MSYS .
Thanks
Please read INSTALL.W32 file in OpenSSL that explains the build procedure with different development suite.
In this file you will find
GNU C (MinGW/MSYS)
It explains the procedure to build it using MinGW with MSYS.
To use it in Netbeans, you need to mention the include path of OpenSSL header files (generated during library compilation) and path of OpenSSL library. I never used Netbeans, so I do not know about it. You need to mention include and library in project settings.

Evince3 Source Code link = http://ftp.gnome.org/pub/GNOME/sources/evince/3.26/
I downloaded the Evince3 pdf reader program source code from the above link. and installed msys2 with gcc and gtk3 librares. Evince3 created using gtk3 module in C. but I don't know how to compile source code of Evince3 for using this program on Windows. Is it possible ?
Thanks.
I was curious to learn how to build Gtk apps on windows, so I did it myself, and it took me around one hour.
I followed this guide, https://blogs.gnome.org/nacho/2014/08/01/how-to-build-your-gtk-application-on-windows.
Note that the author used gedit as example. To install evince, you need to download three files from this directory(get 32 or 64 version of install file), https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-evince.
Modify pkgver to 3.26.0 and sha256sum to the hash value in evince-3.26.0.sha256sum in PKGBUILD file, and follow the rest of instructions.
Other way: It's also possible to install pre-built package from mysys2 repo with compiling the source code. Open the msys2 console and give the following command to install Evince.
pacman -S mingw-w64-x86_64-evince
How to build app with source of openssl, without compiled openssl.dll and libeay.dll ?
I downloaded openssl-0.9.8h, set include paths to path-to-sources/include/. Files located in include/openssl/ it's links to files ../../{crypto/_algo-name_/algosource.h}, and VS do not understand this links.
Actually, you need to build OpenSSL and that will generate the library and header files in the patch specified in makefile. And you should use that include files. These header files are like template files and used while building OpenSSL. See this question.
And search how to build OpenSSL on Windows.
As the problem mentioned by you after compilation, there should not be any need of OpenSSL, you can do it in the following manner:
Generate static library of OpenSSL and use it in your application. Now, after compilation of your application, OpenSSL dlls will not be required.
If your application is very small, you can compile it with OpenSSL static library.
How to build app with source of openssl, without compiled openssl.dll and libeay.dll
You cannot. You need to build the OpenSSL library first.
I downloaded openssl-0.9.8h, set include paths to path-to-sources/include/....
Your next step is to open INSTALL.W32 and read the instructions. Here's an exceprt with most of the steps. But be sure to execute it using a Visual Studio Command Prompt so the tools like cl.exe and link.exe are on path.
If you want to compile in the assembly language routines with Visual
C++, then you will need already mentioned Netwide Assembler binary,
nasmw.exe or nasm.exe, to be available on your %PATH%.
Firstly you should run Configure with platform VC-WIN32:
> perl Configure VC-WIN32 --prefix=c:\some\openssl\dir
Where the prefix argument specifies where OpenSSL will be installed to.
Next you need to build the Makefiles and optionally the assembly
language files:
- If you are using NASM then run:
> ms\do_nasm
- If you don't want to use the assembly language files at all then run:
> perl Configure VC-WIN32 no-asm --prefix=c:/some/openssl/dir
> ms\do_ms
If you get errors about things not having numbers assigned then check the
troubleshooting section: you probably won't be able to compile it as it
stands.
Then from the VC++ environment at a prompt do:
> nmake -f ms\ntdll.mak
If all is well it should compile and you will have some DLLs and
executables in out32dll. If you want to try the tests then do:
> nmake -f ms\ntdll.mak test
To install OpenSSL to the specified location do:
> nmake -f ms\ntdll.mak install
Thomas Hruska of Shining Light Productions offers Win32 OpenSSL. Its a pre-built OpenSSL with a Windows installer. He's been providing it for years.
Once installed, just point to it in Visual Studio. There's no fussing with environments like Cygwin, Perl and scripts to modify source code so that Unix and Linux work on Windows. (That's a dumb idea to me. Windows is Windows, and Linux is Linux. Stop trying to make one act like the other).
From llvm.org I've downloaded llvm-2.6-x86-mingw32.tar.bz2 into c:\llvm and llvm-gcc-4.2-2.6-x86-mingw32-tar.bz2 into c:\llvm-gcc as well as setup a desktop shortcut the following batch file in c:\llvm-gcc which attempts to setup an environment for compiling via the llvm-gcc command line too:
#echo off
color 0E
echo Configuring LLVM environment...
set LLVM_LIB_SEARCH_PATH=%~dp0lib
set PATH=c:\llvm;%~dp0bin;%PATH%
Unfortunately, this setup gives the following error when trying to compile a simple hello world program:
C:\CDev\sandbox>llvm-gcc -o hello.exe hello.c
llvm-gcc: CreateProcess: No such file or directory
I've briefly looked through the LLVM binaries and it appears that the MinGW-based Win32 API and runtime files are already included. I also tried adding the MinGW DLL to c:\llvm-gcc\bin to no avail.
What have I missed in setting up the binary LLVM environment and GCC-based front end on Vista?
Thanks, Jon
Because the GNU/MinGW assembler 'as' was required by 'llvm-gcc' to generate the obj file. The problem can be solved by using:
Install GNU/MinGW binutils, extract the as.exe into c:\llvm-gcc\bin
Install a full MinGW package, add %MinGW%\bin your %PATH%
#rwallace is correct that one needs to also install MinGW's binutils along with the LLVM binary download. I've updated the LLVM documentation appropriately at
http://llvm.org/docs/GettingStarted.html#installcf
As far as I can tell, the answer is that the MinGW distribution supplied by LLVM is not complete, in particular, it doesn't come with the 'binutils' programs.
The recommended solution seems to be to download and install MinGW yourself. However, the MinGW download page seems to be saying this requires 10 different packages to be downloaded and installed separately.
The solution I tried today was to use the MinGW that comes with Qt, which does come in a single package; thus far, that appears to work.
It seems like it is looking for the base MinGW installation in C:\MinGW. I just had this error today using gcc.exe in msys. To solve it, I created a symbolic link from c:\msys to c:\MinGW and everything worked.
Postgres 8.3 is installed on a windows 2008 server.
Ruby 1.8-6 installed.
gem install ruby-postgres.
When trying a simple connect I get
ruby.exe - Ordinal Not Found
The ordinal 284 could not be located in the dynamic link library SSLEAY32.dll.
OK
There seems to be some conflict betweeen the ssleay32 shipped with postgres 8.3 and the ruby 1.8-6
I know I could use the gem postgres-pr but I would prefere to use the ruby-postgres because that is what I use on all my other setup even if most of them is running under linux and not windows.
So the question is, Have any one solved this and how?
Any even better solution, in so far as using the latest binaries for OpenSSL, is to rename both libeay32.dll and ssleay32.dll in both the ruby\bin folder and also the posgresql\lib folder and install the latest OpenSSL from http://www.slproweb.com/products/Win32OpenSSL.html, at the time of writing it was "Win32 OpenSSL v0.9.8j Light" put the dir in the path and away you go, it worked for me! You get the warm feeling of using the most up to date and secure OpenSSL libraries.
Miles Georgi
That is probably the best way to
start, but eventually you will want to
be using ruby-postgres instead. The
trick to getting that driver working
is to copy 2 dll files to your
c:\ruby\bin folder from your
C:\program files\posgresql\lib folder.
I think these 2 files are libeay32.dll
and ssleay32.dll
i think a different approch is to use trust instead of md5 from localhost. Because this need of ssleay should be somthing with authentication I suppose.
To get a minimal thing without doing to much stuff under windows.
use: gem install ruby-postgres
then install the windows version of pgadmin and use all the needed files from there
(cp from pgadmin\bin to ruby\bin or by setting PATH to the pgadmin\bin)
I've never touched ruby or postgres but you are using an old version of openssl than the one it is compiled against. The newest version is openssl-0.9.8j so to build that:
Download and unpack then using visual c++ 2008 express + active perl:
C:\openssl-0.9.8j>perl Configure VC-WIN32
C:\openssl-0.9.8j>ms\do_masm
C:\openssl-0.9.8j>nmake -f ms\ntdll.mak
Just copy the latest binaries for OpenSSL
I'm using libcurl in a Win32 C++ application.
I have the curllib.vcproj project added to my solution and set my other projects to depend on it.
How do I build it with SSL support enabled?
Well, since this post failed badly, I had to dig into the matter myself.
Also check out the other answers and comments for additional info regarding other versions etc.
EDIT: Since I posted this Q there seems to be ready-built binaries made available from the curl homepage. Check out James' answer.
So here goes:
-
Preprocessor
The following two symbols need to be fed to the preprocessor to enable SSL for libcurl:
USE_SSLEAY
USE_OPENSSL
(libcurl uses OpenSSL for SSL support)
Alternatively the symbols can be added directly to a file called setup.h in libcurl, but I'm not too happy about modifying code in 3rd party distributions unless I really have to.
Rebuilding the libcurl library, I now got some errors about OpenSSL include files not being found. Naturally, since I haven't set up the OpenSSL distribution properly yet.
Compiling OpenSSL binaries
I downloaded the OpenSSL 0.9.8 source distribution and unpacked it.
In the root of the source distribution there's a file called INSTALL.W32 which describes how to compile the OpenSSL binaries. The build chain requires perl, so I installed the latest version of ActivePerl.
I had some trouble with the build, which might not be applicable to all systems, but I'll go through it here in case somebody experiences the same.
According to INSTALL.W32:
Run the following commandline tasks with current directory set to the source distribution root:
1> perl Configure VC-WIN32 --prefix=c:/some/openssl/dir
(Where "c:/some/openssl/dir" should be replaced by the dir where OpenSSL should be installed. Don't use spaces in this path. The compilation further ahead will fail in that case)
2> ms\do_ms
For me this step was unsuccessful at first, since I lacked the environment variables OSVERSION and TARGETCPU. I set these to 5.1.2600 and x86 respectively. You may get complaint about OSVERSION being "insane", but look closer, this error is for WinCE and doesn't affect the Win32 setup. To get hold of your OS version, run the 'ver' command from a command prompt or run winver.exe.
3> nmake -f ms\nt.mak (for static library)
or
3> nmake -f ms\ntdll.mak (for DLL)
The source now compiles. Took approx 5 minutes on my laptop.
When compilation is completed, the libs or binaries have been placed in:
distroot/out32 - for static library build
or
distroot/out32dll - for DLL build
Building and linking
Now, back to visual studio and point out the libs and include path for headers. The include files are located in distroot/inc32/openssl.
Remember to add libeay32.lib and ssleay32.lib as linker input.
Rebuild the libcurl project.
Error!
Well at least for me with this version of OpenSSL.
it complained about a struct typedef in one of the OpenSSL headers. I couldn't find any info on this. After an hour of googling I broke my own principle and commented out the typedef from the OpenSSL header, and luckily libcurl wasn't using that symbol so it built fine.
Update: As pointed out by Jason, this issue seems to have dissapeared as of version 1.0.0a.
Now, for confirming that SSL support is enabled for libcurl, run the following code:
curl_version_info_data * vinfo = curl_version_info( CURLVERSION_NOW );
if( vinfo->features & CURL_VERSION_SSL )
// SSL support enabled
else
// No SSL
Simple as that.
Maybe this isn't the answer anyone is looking for, but I simply just downloaded the precompiled DLLs from this link found at http://curl.haxx.se/download.html
I ran the test that sharkin provided, and if( vinfo->features & CURL_VERSION_SSL ) proved to be true.
Following Robert Oschler's advice, here is my comment on the question as answer :
You can build recent libcurl (2012) with native SSL support for windows using the preprocessor symbols: USE_WINDOWS_SSPI and USE_SCHANNEL instead of the OpenSSL ones.
When compiling OpenSSL 1.0.0 on Windows with Visual Studio 2010, it eventually threw a 0x2 error:
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 10.0
\VC\BIN\cl.EXE"' : return code '0x2'
Stop.
It seems that this error will be thrown because of a flag in the perl Configure file, namely -WX.
As the MSDN documentation states:
Treats all compiler warnings as errors. For a new project, it may be best to use /WX in all compilations; resolving all warnings will ensure the fewest possible hard-to-find code defects.
After removing the -WX occurrences in the Configure file and re-entering the commands stated here it built fine and passed all tests.
In my case follow the curl README file was enough.
My configuration is the following:
Visual Studio 2015 (VC14)
Static library
Win64
curl version 7.57.0
OpenSSL 1.0.2
Compilation of libCurl
Download libcurl source there: https://curl.haxx.se/download.html
Uncompress the file and go to the folder curl-7.57.0\projects
Open the README file and follow the instructions, this lead me to do the following:
Downloaded OpenSSL
Extract it and rename it to openssl, put it aside the curl folder, this is important as you'll open the VS project that expect to find openssl there.
Install Perl
Execute the utility build-openssl.bat to perform the compilation of openSSL. With my settings this became the following:
.\build-openssl.bat vc14 x64 release ..\..\openssl\
just runs .\build-openssl.bat -help to know more about the parameters.
After that you can see OpenSSL has been compiled as you got a new folder here: openssl\build\Win64
Open the Visual Studio project curl-7.57.0\projects\Windows\VC14\curl-all.sln
Be sure to set the visual studio project to the build configuration you need (LIB Release - LIB OpenSSL in my case)
Build all
The library is located at curl-7.57.0\build\Win64\VC14\LIB Release - LIB OpenSSL\libcurl.lib
Remarks
Don't forget to define the CURL_STATICLIB preprocessor in your own project
With static library, you will have to links with the dependencies of libcurl, see this answer
You might not want to depend on LDAP, in that case you can disable it by setting the preprocessor CURL_DISABLE_LDAP before you compile libcurl.
If you build with Visual Studio IDE and get 58 odd warnings as the likes of
"inconsistent dll linkage curl_global_init / curl_msnprintf /..."
you should add CURL_STATICLIB to the preproccessor definitions.
so the entire definition line should look like:
USE_SSLEAY;USE_OPENSSL;CURL_STATICLIB.
With this all the warning will disappear.
Some would ignore the warnings and go on using the libs, but then will get corresponding *error*s as the likes of curl_global_init / curl_msnprintf. It can be very annoying.
Hope it can help somebody.
\ fatal error C1083: Cannot open include
file: 'stdlib.h': No such file or directory
NMAKE: fatal error U1077::return code
That error can be solved by executing vcvarsall.bat in Visual Studio.
How to build libcurl C/C++ with OpenSSL (SSL support) on Windows
Install libcurl
Install OpenSSl
Build libcurl with OpenSSL
Installing libcurl
Go to the download page of libcurl and donwnload the ZIP file under Source Archives. In my case it is called curl-7.58.0.zip
Extract the archive and open projects/Windows/VC15/curl_all.sln with Visual Studio.
Installing OpenSSL
Download the windows binary of OpenSSL. In my case, I downloaded the windows installer file Win32 OpenSSL v1.1.0g from the Shining Light Productions distribution.
The installation folder for me is C:\OpenSSL-Win32.
Building libcurl with OpenSSL
In the curl_all.sln Visual Studio solution file, change the build configuration to DLL Debug - DLL OpenSSL.
In the Solution Explorer, right click the project curl and go to Properties.
Under Linker -> General modify Additional Library Directories and add the path to your OpenSSL directory + \lib. In my case, this is C:\OpenSSL-Win32\lib.
Apply and close the properties window.
Right click the project libcurl and do the same as the previous step, add OpenSSL directory + \lib to Additional Library Directories under Linker -> General.
Under C/C++ -> General, add C:\OpenSSL-Win32\include to the Additional Include Directories.
Finally go to Linker -> Input and modify Additional Dependencies. Replace all the lib files to the following:
ws2_32.lib
wldap32.lib
openssl.lib
libssl.lib
libcrypto.lib
Apply and close the properties window.
With the DLL Debug - DLL OpenSSL build configuration still selected, go to Build -> Build Solution.
Copy the two dll files libcrypto-1_1.dll and libssl-1_1.dll from the OpenSSL bin directory (C:\OpenSSL-Win32\bin) to the just created build directory curl-7.58.0\build\Win32\VC15\DLL Debug - DLL OpenSSL.
Validating Build
Inside the build directory, run curld.exe. If it runs with no errors (missing dll, etc.) then your build was successful.
i did "do_nt.bat" for windows 7 rc7100
don't forget "nmake -f ms\nt.mak install" to copy the headers correctly
thanks this did help a lot
Couple of notes in response to and/or in addition to the above..
First, if you don't want to mess with ActivePerl, Strawberry Perl is terrific and worked perfectly for this.
Second, in lieu of using do_ms.bat, I would recommend preferring do_masm if possible since, according to INSTALL.W32,
This is worth doing because it will
result in faster code: for example it
will typically result in a 2 times
speedup in the RSA routines.
Also, build 0.9.8l (L) of OpenSSL was a nightmare so I eventually gave up and reverted to 0.9.8k which built and linked (statically) with libcurl 1.9 without issue.
