Re: Microsoft visual C++ compilation problems

Robin,

Thanks for this I will take a look a bit latter. I have to agree with you about Cmake seems to be the tool of the devil

Subject: Re: Microsoft visual C++ compilation problems

I am the build-master for the Exiv2 project. http://exiv2.org

I never mix GCC and Microsoft Compiled Code.  I believe name mangling is not part of the C++ language and so the code cannot be linked.  Additionally, I never mix code compiled with different versions of MSVC because I believe the compiler generates run-time and other library references that may cause issues.

To make life even more difficult, I encourage you to avoid CMake/Visual Studio as they dance with the elegance of two sumo wrestlers.

I provide build support for Exiv2 on several popular build systems.  Our current MSVC build environment builds libssh (0.55) with openssl (1.0.1j).  We also provide build support for CMake/Visual Studio.

     2012-05-04  23:35     <DIR>    expat     <--- "vanilla" expat   2.1.0  source tree
     2012-05-04  23:35     <DIR>    zlib      <--- "vanilla" zlib    1.2.7  source tree
     2012-05-04  23:35     <DIR>    curl      <--- "vanilla" curl    7.39.0 source tree
     2012-05-04  23:35     <DIR>    openssl   <--- "vanilla" openssl 1.0.1j source tree
     2012-05-04  23:35     <DIR>    libssh    <--- "vanilla" libssh  0.5.5  source tree

You may find our build code helps you to build libssh with MSVC.  Our build environments support VS 2005/8/10/12/13/15 and 2017/RC.  We also support GCC (and/or clang) on MinGW, Cygwin, Linux and MacOS-X.

It's strange, do you know what's causing problems with openssl ? v0-7
should work with openssl 1.0.1. It's openssl 1.1 that requires important
changes.
About the other compiler question:
I'm not qualified enough with windows to tell if that should work or
not. On sane operating systems, mixing compilers for C is not a problem,
but it's windows here :)

Aris,

Thanks for quick response. The first as you say should be easily fixable.

The second I have pulled from Master and yeah it seems to be the C99 thing. I would use V0-7 branch but this simply does not play nice with openssl 1.0.1. I could I guess try openssl 0.9 but that is now unsupported.

   Hi Mark,

   The first error is caused because VS2008 does not fully support c99. I
   think simply removing the broken include should work, we have
   alternatives to stdint.h at least in other include files.
   Which libssh version are you using? I couldn't map the line numbers to
   v0-7 or master. I think that the problem is caused by c99-style
   structure initializations. There are other places in libssh that use
   them and I'm not sure this can be easily fixed without losing the
   advantage of this 15 years-old C feature.

Hi.



I am really stuck trying to build libssh on MSVC Visual Studio 9. I
have installed and built open ssl 1.0.1 and run cmake on lib ssh and
get a make file but now I have 2 problems.



I get this error



\src\external\blowfish.c(52) : fatal error C1083: Cannot open include
file: 'stdint.h': No such file or directory





and also libcrypto will not compile

2>..\..\src\libcrypto.c(862) : error C2059: syntax error : '}'



I’, guessing this is because the Microsoft compiler is not allowing
the C like code.



Has anybody come up against this or any ideas how I could fix this ?



Any help would be gratefully received
