MSB3073: The command "mc :VCEnd" exited with code 1

Question

I am trying to compile log4cpp_x86 in visual studio 2019, but it gives me the error as below,

I tried to change the location of the project from D: to C:, but still problem persist, and also I unmarked the folder as ReadOnly but it also doesn't work.

also when I click on the error i.e marked with MSB3073 it redirects me to the line in Microsoft.CppCommon.targets, which has the xml tag as:

  <Exec Command="%(CustomBuildStep.Command)$(_BuildSuffix)"/>

@HansPassant But there is no post-build command written in Build Events, however I saw that command in C++ project solution file as under, ` mc $(InputPath) ` — chirag pathak, Sep 13 '19 at 11:41
Somebody else had this problem, consider using [the workaround](https://christophep.wordpress.com/2018/02/22/building-log4cpp-with-vs2017/) he found. — Hans Passant, Sep 13 '19 at 11:52
@HansPassant thanks for that link..I tried that solution ,but after executing **add HAVE_SNPRINTF to the Preprocessor definitions** , it gives me **Error : C2084 log4cpp_x86 function 'int vsnprintf(char *const ,const size_t,const char *const ,va_list)' already has a body** — chirag pathak, Sep 16 '19 at 07:42

As link is suggested by the @HansPassant its the half solution in my case, but before following procedure suggested in that link, I replaced the whole log4cpp project having corrupted solution file with xml tag as below,

<CustomBuildStep> <Command>mc $(InputPath)</Command> </CustomBuildStep>

with old project having solution file with below tags,

<CustomBuild Include="..\NTEventLogCategories.mc">

      <Outputs Condition="'$(Configuration)|$(Platform)'=='Release|x64'">$(OutDir)NTEventLogAppender.dll;%(Outputs)</Outputs>
    </CustomBuild>

And then I followed the steps of the link as suggested by @HansPassant, however I didn't followed first step(i.e. download new version of log4cpp) in that link, rather I replaced the project with old project and then followed all the procedure according to suggestions in that link, and that solved my problem.
