[Msys2] It will always install to `/usr` regardless of whether `PREFIX` is set or not

[ghost]

@lcn2 For unknown reasons, it will always install to /usr regardless of whether PREFIX is set or not. Please have a look at it. Thank you.

Please 🙏 run make debug and attach the resulting log file so we can better understand your situation and environment.

UPDATE 0

Meanwhile we will investigate more this evening.

@lcn2 Have you found anything wrong in the makefiles?

@lcn2 Have you found anything wrong in the makefiles?

We did find Makefile problems that were fixed in addressing issue #112.

In regards to where calc installs:

For non-macOS hosts, the default for installation is under /usr/bin, /usr/lib, /usr/share/calc and /usr/include/calc.

The Makefile.config contains some relevant comments:

# Where to install calc related things
#
# ${BINDIR}             where to install calc binary files
# ${LIBDIR}             where calc link library (*.a) files are installed
# ${CALC_SHAREDIR}      where to install calc help, .cal, startup, config files
# ${CALC_INCDIR}        where the calc include files are installed
#
# NOTE: The install rule prepends installation paths with ${T}, which
#       by default is empty.  If ${T} is non-empty, then installation
#       locations will be relative to the ${T} directory.
#
# NOTE: If you change LIBDIR to a non-standard location, you will need
#       to make changes to your execution environment so that executables
#       will search LIBDIR when they are resolving dynamic shared libraries.
#
#       On OS X, this means you need to export $DYLD_LIBRARY_PATH
#       to include the LIBDIR path in the value.
#
#       On Linux and BSD, this means you need to export $LD_LIBRARY_PATH
#       to include the LIBDIR path in the value.
#
#       You might be better off not changing LIBDIR in the first place.
#
# If in doubt, for non-macOS hosts set:
#
#       BINDIR= /usr/bin
#       LIBDIR= /usr/lib
#       CALC_SHAREDIR= /usr/share/calc
#       CALC_INCDIR= /usr/include/calc
#
# Or if you prefer everything under /usr/local:
#
#       BINDIR= /usr/local/bin
#       LIBDIR= /usr/local/lib
#       CALC_SHAREDIR= /usr/local/share/calc
#       CALC_INCDIR= /usr/local/include/calc
#
# However, if you are on macOS then set:
#
#       BINDIR= ${PREFIX}/bin
#       LIBDIR= ${PREFIX}/lib
#       CALC_SHAREDIR= ${PREFIX}/share/calc
#       CALC_INCDIR= ${PREFIX}/include/calc
#
#       NOTE: Starting with macOS El Capitan OS X 10.11, root by default
#             could not mkdir under system locations, so macOS must now
#             use the ${PREFIX} tree.

As we do not know when or where your source was obtained, here is how you can be sure that you can uninstall calc fro the default locations:

make uninstall BINDIR=/usr/bin LIBDIR=/usr/lib CALC_SHAREDIR=/usr/share/calc CALC_INCDIR=/usr/include/calc

Here is how you can force calc to install under /usr/local:

make clobber all install BINDIR=/usr/local/bin LIBDIR=/usr/local/lib CALC_SHAREDIR=/usr/local/share/calc CALC_INCDIR=/usr/local/include/calc

Of course, you will need the appropriate permissions on those directories to uninstall and install.

[lcn2]

With commit b54f68a797491be91f8671ae69c3291aeec74e09 we added comments to Makefile.local about how you can force calc to install under /usr/local, regardless of the system.

In particular, if you add these lines to Makefile.local (or uncomment the recently added lines):

BINDIR:= /usr/local/bin
LIBDIR:= /usr/local/lib
CALC_SHAREDIR:= /usr/local/share/calc
CALC_INCDIR:= /usr/local/include/calc

You will get what you want "by default" without having to add the above mentioned 4 args to your make commands.

[lcn2]

So alas, this is not a bug, but a feature as they say.

We hope the above will help.

As an added bonus. we have added a TODO for calc version 3 to "improve how someone can control where calc installs things". See the TODO list in issue #103.

We will now close this issue, but feel free to add comments or questions to this issue if you are still having problems with where calc installs things.

Sorry, @iahung2 for the confusion!
