clang++ unable to find strerror_s in msvcrt.dll on winxp/2k3

[blueshell]

clang++ got a error:
can't find strerror_s in msvcrt.dll
on win xp/2k3 32bit.
however it works well in win2k8R2 64bit.

I find a similar problem on other projects.
http://sourceforge.net/p/freemat/bugs/588/

FWIW
an bug report for Clang
http://sourceforge.<email address hidden>/
maybe a resolution

The strerror_s function is not available on older versions of windows. The bug is real and I am confirming it, but we don't have plan to make Windows XP compatible builds. You may be able to build cheerp from sources directly on Windows XP.

[blueshell (shell3000)]

The build guide is wrote for Linux users.
i am not familiar with Linux. can you update a guide for windows?
but i will try to build clang++ and clang with your guide.

[blueshell (shell3000)]

According to the experience, the solution to run in winXP/2k3 with no code changed:

1 install VS2012 SP1
2 set PlatformToolset to Visual Studio 2012 - Windows XP (v110_xp)
3 set RuntimeLibrary to MultiThreaded

or just batch replace *.vcxproj
from <PlatformToolset>v110</PlatformToolset> to <PlatformToolset>v110_xp</PlatformToolset>
from <RuntimeLibrary>MultiThreadedDLL</RuntimeLibrary> to <RuntimeLibrary>MultiThreaded</RuntimeLibrary>

I do not find the command in cmake to make above arguments as default.

but i got lots of compile error on VS2012;and i only find the project to generate clang,but no clang++

[Alessandro Pignotti (a-pignotti)]

If you are able to generate the clang executable you are actually done. clang++ on Windows is simply a copy of the same executable with a different name. It would be very helpful if you could document the procedure to build on Windows, including for XP, on our wiki:

https://github.com/leaningtech/cheerp-wiki/wiki/Windows-build-instructions

[blueshell (shell3000)]

yes , i change some code to improved compatibility for vs2012,now it can be run in xp;
the file size is 18M only,but the file you provided is 45M.did i miss something?

but when i replace all things in cheerp\bin

and run the example i got a error.

example.cpp:3:10: fatal error: 'cheerp/clientlib.h' file not found

did i override something important?

i will write a wiki document for my process.

[blueshell (shell3000)]

if i add arg -I"C:\cheerp\include\client" for clang++
i got another error

 C:\cheerp\include\client\cheerp/types.h:24:10: fatal error: 'utility' file not
      found
#include <utility>

[Alessandro Pignotti (a-pignotti)]

What is the cmake command you use to create the visual studio projects?

Also, please create an empty file, for example "empty.cpp" and post the result of the following command

    /opt/cheerp/bin/clang++ -target cheerp -E -x c++ -v empty.cpp

What is the command you are using to build the example?

The different in size depends on the fact that our build is a static build cross-compiled using Mingw, while you are doing regular build. Don't worry about the smaller size, it should work.

[blueshell (shell3000)]

I'v update the wiki with my step and convert log.
i use cmake as follows
cmake -DCMAKE_INSTALL_PREFIX=/opt/cheerp -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="ARM;CheerpBackend;X86" ..

i made empty file named empty.cpp and call
clang++ -target cheerp -E -x c++ -v empty.cpp
the info is:

[blueshell (shell3000)]

i think i need to change

#define LLVM_PREFIX "/opt/cheerp"
llvm\Config\config.h
add
llvm\Config\llvm-config.h

i think i need change the
cmake -DCMAKE_INSTALL_PREFIX=/opt/cheerp also?

but which command should i use?

[blueshell (shell3000)]

I find that the path is hard code as "getProgramPaths().push_back(LLVM_PREFIX "/bin");"
i think we should get the path of the executable file runtime and generate the include path and library path.

I simply #define LLVM_PREFIX c:/cheerp
and i am checking whether it works.

[Alessandro Pignotti (a-pignotti)]

You should change the prefix for the windows build, the right command is

cmake -DCMAKE_INSTALL_PREFIX=c:\cheerp -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="ARM;CheerpBackend;X86" ..

LLVM_PREFIX is automatically defined from the install prefix you tell cmake

[blueshell (shell3000)]

yes, i am compiling.
but i think the better way is get the path of the executable file runtime ,and generate the include path and library path.
or else, if i install the software to d:\cheerp\ the software will not find the correct path.

[blueshell (shell3000)]

can you give me the git version of Cheerp 1.0?

[Alessandro Pignotti (a-pignotti)]

From a cloned git repository you can extract any version using the "git checkout" command, for example

git checkout cheerp-1.0

I have noticed only now that we have not published source packages for LLVM/clang version 1.0. I'm going to fix this, but in the mean time please use the above command to retrieve version 1.0. Remember that, since llvm and clang are two different repositories you need to do "git checkout cheerp-1.0" in both of them.

[Alessandro Pignotti (a-pignotti)]

You can now find the 1.0 Cheerp source for LLVM and clang here: https://launchpad.net/cheerp/+download

[blueshell (shell3000)]

Ok.i will try it.
is my libc.bc(released in 1.0 version) too old for the new clang++?
and then i got the error?

[blueshell (shell3000)]

i'v found the different.
in llvm\Bitcode\LLVMBitCodes.h enum AttributeKindCodes
in v1.0 ATTR_KIND_TYPED_INTRINSIC = 41,
and in the lastest version ATTR_KIND_RESERVED = 41,

so i think it got a error because cheerp/lib/libc.bc is old.
so if i need to use lastest version , i need compile those libs also?

[blueshell (shell3000)]

cheerp-1.0
do not have
#include "llvm/Cheerp/ReplaceNopCasts.h"
#include "llvm/Cheerp/StructMemFuncLowering.h"
those two files.
i copied them from higher version. hopes nothing incompatible form 1.0 version.

[blueshell (shell3000)]

CGBuiltin.cpp(4514): error C2039: “cheerp_make_complete_object"

lots of compile error.
plz publish source packages of v1.0.

[Alessandro Pignotti (a-pignotti)]

The source package is now available here:

https://launchpad.net/cheerp/trunk/cheerp-1.0/+download/cheerp-llvm-clang-1.0.tar.gz

The binary file format has indeed changed since 1.0, but I'm not sure if building the libc library is feasible on windows.

[Alessandro Pignotti (a-pignotti)]

I'm currently working on a build fix to support for XP and 2k3. I will backport the fix and make a new 1.0 windows build after testing.

[blueshell (shell3000)]

i can't generate libc.bc etc. for lastest version,because the makefile and .sh is only for Linux.
can you give me the lastest *.bc of libs?

I generate 1.0 execute files with "cheerp-llvm-clang-1.0.tar.gz"
and get a error

I'v complete the version.
and compile "example.cpp" successfully in windows 2003.

here is a package build from src 1.0.
maybe someone else needed.

[blueshell (shell3000)]

notice:
llvm-tblgen.exe crash when generate ARMCommonTableGen and X86CommonTableGen in vs2012 windows 8.1

Building X86GenRegisterInfo.inc...

I don't know what those 2 projects are.
but clang++ and llvm-link are generate successfully.

You can find a working 1.0 release for Windows XP here: https://launchpad.net/cheerp/trunk/cheerp-1.0/+download/Cheerp-1.0-winxp-compat-Windows.exe

[Alessandro Pignotti (a-pignotti)]

By the way, current git master of Cheerp also builds with VS2012 without any modification
