Hi,

I just found my Outlook was configured to use HTML mail which may have

Hello,

Let's say, you have an executable (foo.exe) and DLL (bar.dll). In debug
build, the DLL is renamed to "bar-d.dll" (See List-1). Now, the
executable wants to LoadLibrary() the DLL. (See List-2). Is it possible
to pass the actual DLL filename to foo.exe so that foo.exe can load the
correct DLL for release / debug builds?

##########################
# List-1
##########################
import virtual-target : add-prefix-and-suffix ;

rule rename ( name : type ? : property-set ) {
    local postfix ;
    local properties = [ $(property-set).raw ] ;
    if <variant>debug in $(properties) { postfix += d ; }
    
    local result = $(name)-$(postfix:J=-) ;
    
    return [ add-prefix-and-suffix $(result) : $(type) : $(property-set)
] ; }

lib bar : bar.cpp
        : <tag>@rename
          <link>shared
;

exe foo : foo.cpp
        : <define>FOO_FILENAME=????
;

install . : bar foo ;

##########################
# List-2
##########################

#define STRING(s) # s
#define XSTRING(s) STRING(s)

int main(){
  // ...
  LoadLibrary(XSTRING(FOO_FILENAME))
  // ...
}
