It's not cygpath at fault here. It's how make works. Your patsubst
with a shell call in the replacement string simply doesn't work as
intended.
For testing purposes, replace cygpath with this simple test application:
$ cat > mycygpath.c <<EOF
#include <stdio.h>
int
main (int argc, char **argv)
{
int i;
for (i = 1; i < argc; ++i)
{
fprintf (stderr, "ARGV[%d] = '%s'\n", i, argv[i]);
if (argv[i][0] == '-')
continue;
if (argv[i][0] == '/')
{
if (!strncmp (argv[i], "/cygdrive/c/", 7))
printf ("C:/%s\n", argv[i] + 7);
else
printf ("C:/cygwin64/%s\n", argv[i] + 1);
}
else if (!strncmp (argv[i], "./", 2))
printf ("%s\n", argv[i] + 2);
else
printf ("%s\n", argv[i]);
}
return 0;
}
EOF
It works exactly as cygpath for your testcase, but additionally
it reproduces the exact incoming argument string on stderr:
$ gcc -o mycygpath mycygpath.c
$ ./mycygpath lib1 ./relative.vhd /cygdrive/c/Windows/absolute.vhd
ARGV[1] = 'lib1'
lib1
ARGV[2] = './relative.vhd'
relative.vhd
ARGV[3] = '/cygdrive/c/Windows/absolute.vhd'
C:/Windows/absolute.vhd
Now change your Makefile like this:
$ cat > Makefile <<EOF
FILES = lib1 ./relative.vhd \
lib2 /cygdrive/c/Windows/absolute.vhd
convert_absolute_paths_to_windows_paths:
@echo 1: $(patsubst /%,$(shell ./mycygpath -m /%),$(FILES))
@echo 2: $(shell ./mycygpath -m $(FILES))
EOF
And now run make:
$ make
ARGV[1] = '-m'
ARGV[2] = '/%'
ARGV[1] = '-m'
ARGV[2] = 'lib1'
ARGV[3] = './relative.vhd'
ARGV[4] = 'lib2'
ARGV[5] = '/cygdrive/c/Windows/absolute.vhd'
1: lib1 ./relative.vhd lib2 C:/cygwin64/cygdrive/c/Windows/absolute.vhd
2: lib1 relative.vhd lib2 C:/Windows/absolute.vhd
Observe what make gives to the first mycygpath call. cygpath gets
a literal "/%" string. mycygpath as well as cygpath will *correctly*
generate "C:/cygwin64/%", and then, *after* the call to $(shell), the
% substitution of patsubst will be performed.
