I used Borland C++ from 1994-1997
Try:
tcc -ms program.c -oprogram.obj
Long ago when I used Borland C++ there was also command line options to use
floating point emulation (the default) and another to use the x87 library. I
don't know if such is the case with newer versions (that is how long it has
been since I used the Borland compilers.) -f87 for 8087 and -f287 for 80287.
This would precede the input file name.
After you compile and have the .obj(s) then you need to link it. When
I used the compilers, I had to use a memory model.
c0t.obj tiny model(used for things like .com files. The program segment
prefix (PSP) is different for this model and there is no stack segment)
c0s.obj for small model (appropriate for the source given.)
c0c.obj for compact
c0m.obj for medium
c0l.obj for large
c0h.obj for huge
The linker that came with Borland was tlink.
tlink /c \Borlandc\lib\c0s program, program,,\borlandc\lib\maths
\borlandc\lib\cs
The /c makes the symbols case sensitive. the next two items are the .obj
files for this compile. First the small version standard c startup module
(along with the path) then the program.obj we compiled before. the next
item is the output executable: program.exe. the ommited option is for a map
file. Last are the two small version libraries used: maths.lib for the sqrt
function, then cs the small version standard c library.
Keep in mind that I seldom use command line compilers these days and it has
been years since I've used Borland. Let me know if my take on dos-mode
command line compilers is too medieval. I hope this is at least partly
useful. I have the documentation around here somewhere in a box. If I find
it I will scan the relevent sections for you.
