What can I change to make it work?

Thanks in advance.

I would try the beta package release linked in this question. It has fixed several issues that seem to have occurred after a major update. It fixed multiple issues for me.

Should work if you remove the dot… I will update it

Thanks for your answer, but the link is no longer active.

i tried this beta-library: ToradexCeLibraries_2.1b4350-20180319, but even this library does not work. It still comes the same error message.

The solution is not in the actual libraries, but in the project file of your application:

The following sections of UpdateLib_Demo.vcxproj have been updated to fix the problem. Particular functions (such as for memory allocation) are available in different flavours in Visual Studio’s standard C library ( libcmt.lib) as well as in the OS. The changes below force the linker to use the OS version of these functions.

Hello andy.tx,
i have changed the project file to your specifications, and now i get this error message:

1>LINK : fatal error LNK1181: cannot open input file ‘corelibc.lib’

Where can I find this Lib?

Dear @troubadix

The corelibc.lib is part of the SDK, typically located at
C:\Program Files (x86)\Windows CE Tools\SDKs\Toradex_CE800\Sdk\lib\ARMV7\retail\

This path should be searched automatically if your Toradex_CE800 SDK is properly installed.

Regards, Andy

i think the SDK is installed properly - but in this path there is no corelibc.lib.

@troubadix,

msvcrt.lib is same as corelibc.lib. So, could you please

 Copy C:\Program Files (x86)\Windows CE Tools\Toradex_CE8_SDK\Sdk\Lib\ARMV7\retail\msvcrt.lib
   to   C:\Program Files (x86)\Windows CE Tools\Toradex_CE8_SDK\Sdk\Lib\ARMV7\retail\corelibc.lib

and use it.

Thanks raja.tx. Now it’s working.
