[mercury-users] mmc --make and MLLIBS

[Peter Ross]

Hi,

I have the following line in my Mercury.options file

MLLIBS=libexpat.lib

and then call mmc --make

Making Mercury\int3s\generic_xml.int3
Making Mercury\int3s\mexpat.int3
Making Mercury\int3s\mexpat.xml.int3
Making Mercury\ints\mexpat.int
Making Mercury\int0s\mexpat.int0
Making Mercury\ints\mexpat.xml.int
Making Mercury\cs\generic_xml.c
mercury_compile.exe: can't find source for module `libexpat.lib'.
Error: system command received signal 1.
** Error making `Mercury\cs\generic_xml.c'.

I can fix that problem by commenting out the MLLIBS variable.

I add MLLIBS=-lexpat
% Creating initialization file...

You can see the location of -lexpat in the command.

I then change back to MLLIBS=libexpat.lib and it does't appear where
-lexpat is in the command.
