libCurl x64 build problems Visual Studio 2013 (x64) Visual Studio & CMake

Question

I am trying to build libCurl x64 on Windows 8.1 x64 and I am having linker errors. I need to be able to do this as I need to create a 64 bit debug version of the library so that I can trace some strange FTP related protocol issues I am encountering.

The fundamental error output (trimmed for brevity) is as follows

1>------ Build started: Project: ZERO_CHECK, Configuration: Debug x64

Please help - I have searched the forums and stackoverflow for something similar but to no avail. I was able to successfully build in x86 (win32) mode but I am having linkage errors when I target x64.

Step 1: Download latest CMake 2.8.12.2 & update the Windows PATH environment (in my case I am using the MINMGW32 bash shell prompt, but I get exactly the same linkage problems if I use the native visual studio 2013 x64 shell to run cmake from)

$ export PATH=$PATH:/c/Program\ Files\ (x86)/CMake\ 2.8/bin

verify that the path and version of Cmake on windows

$ cmake --version cmake version 2.8.12.2

Step 2: extract curl-7.35.0 into a folder c:\temp\curl-7.35.0" and make a parallel folder "c:\temp\curl-7.35.0\build".

Step 3: Change into the build folder and run Cmake targeting "Visual Studio 12" as the desired Visual Studio Solution/project combination to create

$ cmake -G "Visual Studio 12" ../curl-7.35.0

This produces a ton of output as follows, but it does also create a workable visual studio solution targeted for a machine type X86.

Step 4: Within Visual Studio change the target type to x64 using the configuration manager (where I had to select a new platform and I selected X64 and copied the settings from Win32). This is a pretty straight forward step that is used to target an X64 machine target, so as not to confuse, I have not included the step by step details here.

Step 5 Select the solution and rebuild all from Visual Studio 2013 and the output above will ensue.

Side note: Although I do not really need SSL for now, it would be nice to know how to tell CMake where the location of the LIBSSL things are located (I downloaded a package of pre-built libraries (both 32 and 64 bit including the SSL and other libraries) from http://www.confusedbycode.com/curl/, however these are release mode and I need to be able to debug libCurl to see what is going on with some strange problems I am encountering. I am a newbie when it comes to configuring CMake however it looks to be a really promising tool for those of us that target multiple platforms but prefer to develop on windows. It certainly is easier than the gnu autotools.

Answer 1

It looks like the CMake generated solution file was not expecting X64 as a potential target. I found a slight variant on the problem here.

This is a pic of the X64 Command Line Options - as you can see after I changed the configuration manager to use X64 the

After making these changes the project finally linked and I was able to generate a debug version of the library.

Answer 2

The trick for building 64-bit libcurl with on a clean x64 / Win 8.1 / VS2013 box is to first run the Visual Studio vcvars.bat batch file with the "amd64" argument. This sets up the make environment properly.

Then you can run the "nmake..." command as outlined in winbuild\BUILD.WINDOWS.txt.

Answer 3

I had the same problem (module machine type 'x64' conflicts with target machine type 'X86') when building CURL from command line in the folder "curl-7.40.0\winbuild" as described by the file "BUILD.WINDOWS.txt" there. I used the following command line: nmake /f Makefile.vc mode=dll ENABLE_WINSSL=no ENABLE_IDN=no GEN_PDB=yes ENABLE_SSPI=no MACHINE=x64 DEBUG=no. It specifies "Using the Visual Studio command prompt Shell", but ... there are more of them: "Visual Studio 2005 Command Prompt" does not work, "Visual Studio 2005 x64 Win64 Command Prompt" does (for 64-bit). It worked for me with Visual Studio 2005, but they say it only needs "Platform SDK".

Answer 4

Place this script in Curl's source directory (I name it winbuild.bat) and run it if you don't need the curl project to compile with the rest of your solution:

@ECHO OFF
CALL "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64\vcvars64.bat"
CD winbuild
nmake /f Makefile.vc mode=dll WITH_DEVEL=..\..\dll64 VC=12 WITH_SSL=dll GEN_PDB=yes MACHINE=X64
CD ..
EXIT /B 0
