What I have done is to try to clean up my src location by moving some files into sub-folders. The files I moved don't get changed very often, and when I port to linux, it helps some to only have to deal with files that have been changed.

I took my src directory, and added some sub directories,

src/
src/src_server/
src/src_main/

I moved some cpp files from src/ to src/src_server/ and then added the compile rule,
Code:
# compile src c++ server objects
$(BDIR)/%.o: $(SOURCELOC)/src_server/%.cpp
    $(CC++) $(CFLAGS) $(VFLAGS) -c -o $@ $<

This is what "worked fine". The src files in src/src_server/ got compiled and the objects placed in BDIR.

I tried the same thing with some fortran files, moving them to src/src_main/ and adding the compile rule,
Code:
# compile src gfortran main function objects
# compile src g77 objects
$(BDIR)/%.o: $(SOURCELOC)/src_main/%.FOR \
                      $(SOURCELOC)/src_main/COMMON.BLK \
                      $(SOURCELOC)/src_main/PARAM.DAT \
                      $(SOURCELOC)/src_main/ATSYMB.DAT
    $(FCOMP) $(FCFLAGS) -c -o $@ $<

When I run the make, I get a message that there is no rule to compile the object for the first src file and it quits. I need to reproduce the message and then I will post the output. Under cygwin, I am using make 3.81. I am also doing this in ubuntu, so I will have to boot into that to get the version that is installed there.

At first, I thought the issue may have been with COMMON.BLK, PARAM.DAT, etc, but I thought that would generate a compiler error, not a message about a missing rule. I am not sure why these files need to be included in the compile rule like they are, since they are included in the src, but I don't remember where I got the syntax for this and it's harder to find good information about Fortran make files than other languages.

I made the changes in my cygwin make file, and everything worked fine. I need to go back over to linux and see if the problem persists there or not. I'm not sure if I did anything differently this time or not.

mlib_SignalEmphasize_S16_S16_Sat(3MLIB) 		    mediaLib Library Functions			   mlib_SignalEmphasize_S16_S16_Sat(3MLIB)

NAME

       mlib_SignalEmphasize_S16_S16_Sat, mlib_SignalEmphasize_S16S_S16S_Sat, mlib_SignalEmphasize_F32_F32, mlib_SignalEmphasize_F32S_F32S - signal
       pre-emphasizing

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalEmphasize_S16_S16_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_S16S_S16S_Sat(mlib_s16 *dst, const mlib_s16 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_F32_F32(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);

       mlib_status mlib_SignalEmphasize_F32S_F32S(mlib_f32 *dst, const mlib_f32 *src, void *filter, mlib_s32 n);

DESCRIPTION

       Each of these functions applies the preemphasizer to one signal packet and updates the filter states.

       For monaural signals, the following equation is used:

       dst[i] = src[i] - alpha*src[i - 1]

       where i = 0, 1, ..., (n - 1); src[-1] = 0.

       For stereo signals, the following equation is used:

       dst[2*i]     = src[2*i]	   - alpha*src[2*(i - 1)]
       dst[2*i + 1] = src[2*i + 1] - alpha*src[2*(i - 1) + 1]

       where i = 0, 1, ..., (n - 1); src[-2] = src[-1] = 0.

PARAMETERS

       Each of the functions takes the following arguments:

       dst	       Destination signal array.

       src	       Source signal array.

       filter	       Internal filter structure.

       n	       Number of samples in the source signal array.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
